LSA Update: Pre-AirVenture Oshkosh 2021 — Aircraft, Products, Dealers, Achievements

By Dan Johnson || 10 Comments

Well, FINALLY, AirVenture Oshkosh is barely a week away. It seems like forever, doesn’t it? It has been two years but feels like a decade. I hope you can attend, but if not, I plan to be on-site all week gathering the latest about Light-Sport Aircraft, Sport Pilot kits, and ultralights.

In this edition of “LSA Update,” I’ll cover an update about…

1️⃣ Jabiru and their AirVenture activities; 2️⃣ Beringer’s new SensAir system that works with your smartphone; 3️⃣ an impressive father-and-daughter partnership forming a new dealer for Seamax; 4️⃣ a preview of the new Dragon powered paraglider single-place quad; and, 5️⃣ competition successes for E-Props and Polini engines.

Let’s get this show underway…

Jabiru USA

One of the earliest Light-Sport Aircraft to be approved was the Australian Jabiru brand.

Not only was Jabiru one of the first approved SLSA (#22) but also one of the most prolific with SLSA #22 J250-SP, #23 J170-SP, #40 Calypso SP, #67 J230-SP (redesignated as J230-D in 2013), and #142 J170-D. The “SP models came from an earlier U.S.-based manufacturing arrangement. The “D” denotes the manufacturing now conducted in Australia.

When you are an early entrant you have time to get the details right and flesh out the operation.

Now in the capable hands of Scott Severen, who runs US Sport Planes and took over from Jabiru USA founder Pete Krotje, Jabiru has matured to one of the leading LSA suppliers. It is the only Australian fixed wing aircraft brand to successfully enter the U.S. market.

The company remains a member of a very select club that manufactures both airframe and engine.

All Jabiru models appear compact but actually have spacious interiors; especially the latest J230-D has a cavernous aft area (where people sit when the same base airframe is used to make a four seater). A third door for this purpose serves U.S. pilots by making the loading of luggage (or your pet) easier.

With its 4th Generation six-cylinder engine producing 120 horsepower, Jabiru J230-D will satisfy a lot of pilots. Stop by their space at AirVenture and perhaps you’ll meet some of their owners that will attend another annual Jabiru Owners Group (JOG) gathering.

Beringer

Known far and wide for their distinctive orange-ish wheels, Beringer has built a premium brand serving aircraft from the lightest LSA to Cirrus’ SR-series.

The France-based company with a permanent U.S. operation has numerous products in support of airframes including the unique locking tailwheel and their wheel shocks. Now, they have something new.

Beringer’s SensAIR™ system is connected to a mobile app on your smartphone (image) thanks to pressure and temperature sensors fitted to your Beringer rim. Sensors are normally switched off to save the battery (2 to 3 years lifetime) and are activated when the smartphone is detected within a 30-foot radius (10 m).

Low pressure and temperature levels are set by the user on his smartphone so he or she can receive a notification.

No need to crawl under your plane to check pressure anymore, thanks to SensAIR you can check your pressure before and during each flight! SensAir is available now for 4-, 5-, 6-, and 8-inch wheels.

Seamax

With fabrication in Brazil, Seamax has been in the U.S. market for many years, earning FAA acceptance as #63 in our SLSA List.

In the last few years Seamax has substantially upgraded their U.S. representation with full-time facilities adjacent to the prestigious campus of Embry Riddle Aeronautical University. From this ideal location they can cover the Eastern U.S.

Now, Seamax is pleased to announce a new dealer based in Tulsa, Oklahoma. The seaplane maker now offers support, training, and sales for several Midwestern states. The new business is called Central Seaplanes and they become the official sales agent and brand representative for Oklahoma, Arkansas, Missouri, Kansas, Colorado, New Mexico, and Texas.

Central Seaplanes will provide mechanical and maintenance service to Seamax aircraft in association with Johnson Aviation of Tulsa and plans to provide flight training in association with Destinations Executive Flight Club of Tulsa.

The Oklahoma dealer recently acquired two fully-equipped Seamax M-22 aircraft to their fleet and. One M-22 is equipped with IFR gear, which allows a pilot in training to log instrument hours at competitive rates.

Central Seaplanes, LLC is a father-daughter, veteran-owned business represented by Kira and Todd Lang.

Todd is a former fighter pilot with 40 years of aviation experience and 11,000 logged hours with CFI, CFII, and MEI instructor credentials. Currently, he is an international Boeing 767 Captain for a major U.S. airline. Todd also holds a Master’s degree in Business Administration from Embry Riddle.

Kira has an Associate degree in aircrew safety systems technology, a Bachelor’s degree in aviation management and a Master’s degree in aviation and space science. She is currently finishing her doctorate. Kira received her Private Pilot certificate when she was 18 years old.

Kira said she has always dreamed of starting her own business with her dad. She has a passion for aviation and has thrived in the industry. She intends to dedicate her time to the success of Central Seaplanes and their association with Seamax aircraft.

Dragon PPG

Welcome to Dragon PPG (powered paraglider).

This quad — a term describing the four wheeled carriage some powered paraglider enthusiasts prefer — “is a new concept,” said Erin Thorson about designer Dan Feldman‘s work. Dragon will make its official debut at AirVenture 2021. Thorson is a 30+ year A&P and former Air Force aviator.

“Considerable research and thought have been put into producing a high quality seated powered paraglider that meets all FAR 103 requirements,” wrote Erin. Dragon PPG is aimed at taller and heavier PPG pilots. The design features a roll cage for protection. Such a configuration is common in powered parachutes (different aircraft, if you aren’t familiar) but quads have previously been very light weight construction that mainly aimed to provide some structure to accommodate wheels, and not much more.

Based on Rotax 503 power, Erin described thrust of the engine as “incredible!” Dragon was weight tested at 4Gs assuming a 220-pound pilot. Commonly, powered paragliders prefer the lightweight, higher-revving Polini engine (see next news item).

“Last week, Eric Dufour, a world-renowned paragliding pioneer and well respected paramotor instructor, personally flew the Dragon PPG and loved everything about it,” wrote Erin. “I have witnessed the Dragon fly; it is a rocket!”

Dragon PPG is made in the USA.

“The challenge (and frustration) for many quad PPG pilots is a lack of power and thrust and overall structural integrity,” continued Erin. “Dan set out to design a wheeled powered paraglider [carriage] using heavy-wall aluminum for the main structural components with aluminum clamp devices and U-channels clamps to secure the tubing. The reason is primarily to add strength to the tubing without drilling of holes which can weaken the structural integrity of the frame.”

He reported the Dragon frame and engine have been designed to meet FAR 103 requirements. The Dragon frame itself can also be purchased as a stand alone frame without engine if the customer desires.

E-Props and Polini Engines

In early July 2021 flying enthusiasts participated in the second edition of a STOL competition for ultralights (with engines limited to 100 horsepower) in the south of France. The contest was organized by the French Federation, FFPLUM.

“The propeller is a very important equipment to succeed in this kind of competition,” the company wrote. “E-Props is proud to have won the first three places.”

Earlier, on the weekend of June 17, 18, and 19, the French Open Training Slalom 2021 at Sevins Le Lac, “the podium was monopolized by pilots using Polini Thor engines,” boasted the Italian engine maker. Champion Alexandre Mateos, an ace of this sport, dominated results winning in his debut with the new Thor 303. Commonly, E-Props have been paired successfully with Polini.

In second position was Jeremy Penone using the super-tested Thor 250.

In third, winning the bronze medal, was Marie Mateos also using the new Thor 303. Marie reached a new goal with Thor Polini engines. After previously winning the female category, in this recent competition she was the first woman to be on the winner’s podium ranked equally with male pilots.

In a similarly timed event called “Slalomania,” in Bornos in the south of Spain, the Slalom Open Spanish Championship took place. “Once again the pilots powered by Thor 303 engines confirmed this engine is superior for powered Paragliders,” reported Polini.

Of the 21 pilots that took part to the competitions, 16 chose Polini Thor engines.

…but, of course, all the above is merely the tip of a large iceberg.

I hope to achieve sensory overload at Oshkosh ’21 and I will do my best to transmit that excitement to you. Watch for the bright orange logo denoting coverage from the big show.

Off we go!

Streaking through the Sky — JMB Aircraft’s VL3 Gets Clean and Goes Fast

By Dan Johnson || 10 Comments

The age of Light Personal Aircraft is not far off in the future but is that where “fast-glass” LSA are headed?

Certainly, some LSA producers have ambitions for four seat cruisers or tougher bush aircraft or larger load-carrying aircraft to satisfy pilots that want more capability from their aircraft.

Those goals are fine, of course, but they are not what stimulates leaders and engineers at JMB Aircraft, a restless bunch that loves flying their screaming machine as fast as they can.

How fast is it? I went aloft with dealer Kyle Schluter to find out.

I also learned about the fuller product line and what Sport Pilot certificate holders can do to own and fly one of these impressive aircraft. (Article updated 7/17/21)

Orange Lightning in the Sky

Maybe it doesn’t look familiar but VL3 has already been seen by Yankee pilots under the brand name Gobosh and with the model designation 800XP. Gobosh emerged in the early days of LSA. Today you know this aircraft as VL3 and it doesn’t seem the same.

The fellows importing 800XP from then-producer Aveko rebadged the aircraft for the American market. It featured fixed gear and a fixed prop to meet the LSA regulations of the day. They also added wing area and for good marketing measure, they added sexy upward-curved winglets.

Irony: The older model is essentially the LSA version that JMB plans for the U.S. market. So, yep, while the model in this report is the speediest version, a simpler — and LSA compatible today, even before the 2023 regulations — model is already waiting for American pilots that many need or prefer an LSA.

No question though… what gets most pilot hearts beating harder is the speed VL3 has been able to achieve with a Rotax engine.

VL3 was already known as a very fast flyer …and then Rotax introduced their 141-horsepower 915iS. Engineers at JMB eagerly accepted the challenge of adding the potent new powerplant to their sleek airframe and the results are strong.

In the present time — before big changes coming with the so-called Mosaic regulation — everyone knows LSA are limited to 120 knots indicated at maximum cruise at sea level. Note that most of the speed references in this article are true airspeed, and FAA does not dispute that this figure can be significantly higher than at sea level.

When American builders go the Czech and work on building their kit to qualify, as presently needed, as an Experimental Amateur Built aircraft, they can take full advantage of the speed potential of this airplane. Of course, that procedure may change after 2023 when LSA are allowed to fly faster or when VL3 can become a Light Personal Aircraft with even more capability.

You should note that JMB, along with most Euro designers, likes to quote max speeds in not only true airspeed but in kilometers per hour. I don’t blame them. It makes the number higher and if you don’t think this has any meaning then you probably don’t understand a product priced at $29.95, either. People are affected by a number and 370 kilometers per hour certainly does sound fast.

VL3 has retractable gear with full gear door covers.

VL3 is able to achieve these speeds thanks to a very clean all-carbon-fiber airframe. The model also has a relatively short span (under 28 feet).

The company lists climb rate at 2,000 feet per minute, a 2,000-kilometer (1,250 statute mile) range and a fairly modest 600-foot takeoff roll. Those are certainly very strong bragging rights, and on my recent flight, I found these numbers believable.

Safety Figures High, Too

Safety is important to JMB engineers as well. I flew in a VL3 with an airframe ballistic parachute. That’s one feature but hardly all. In fact, it’s for last-resort use.

JMB reports that VL3’s airframe has been subjected to a rather amazing +15 Gs of positive load and –8 Gs of negative load. That occurred in a test to failure; normal operational limits are +5 –2.5 Gs. VL3 is not intended for aerobatics but can stand up to the rigor of higher speed flight.

Kyle Schluter fills VL3’s left tank (32 gallons can be carried). In the foreground you see the parachute mount location with the breakaway edges.

Pilots have tested VL3 up to 248 knots indicated airspeed (459 kph or 285 mph) to determine if flutter appears. It did not.

An Angle of Attack (AoA) indicator appeared on the Garmin G3X to help the pilot stay within safe speeds. As do many LSA producers, JMB includes an ELT, promotes on-screen traffic advisories, plus stall strips have been fitted near the wing/fuselage junction to improve controllability at slower speeds.

Given JMB salesman talk about speed all the time, you may start to wonder as I did. OK, fine, it blazes, I thought, but what are its slow speed characteristics? Some previous fast-glass designs have so focused on speed that a short off-field landing could be threatening because landing speeds remain high. Not on VL3.

VL3 has a well-refined automotive-like interior finish.

As Kyle approached to land, he lowered flaps to 15 degrees; this setting is used for takeoff as well. Using 33 degrees substantially steepened approach and the full-down 55 degrees of split flaps are needed only for the shortest field.

As he lowered flaps and worked to slow down this race horse, I was pleased to see how well behaved VL3 remained.

I had a clue because we did a series of stalls and VL3 had already shown great slow speed stability and control but also remarkably slow speeds. Stall happens modestly in the low 40 knot range. From 42 knots or so stall to 165 indicated top cruise, we see the 4:1 slow-to-max ratio that is the holy grail of airplane design.

Now in the US of A

With import operations based on the West Coast, Alion Aviation engaged dealers in the Midwest and the east to help promote and service the aircraft.

Left arrow identifies the prop control on VL3. The right arrow shows presets you can make, in this case, takeoff setting. Note parachute handle at right.

One of these is a father and son team, Dirk and Kyle Schluter, located in Ohio. They will provide sales and service to many eastern states from Maine to Florida. Another dealer group, David Pauly and Aaron Young, is based in Wichita, Kansas serving the central states while Alion Aviation importer and company CEO Adam Coubal is based in California and serves the West Coast.

More to Come… On the flight I took with Kyle, we shot video for a Video Pilot Report to follow in which you will learn more about speeds, power settings, engine temperatures, flight controls, stall characteristics, slow flight, maneuvering, takeoff and landing and more. Watch for that video after AirVenture 2021.

No question about it — VL3 is one of those aircraft that will catch your attention.

Good luck catching one in the sky.

Newest SLSA in the Fleet: Flight Design’s F2 (also a Precursor to LPA?)

By Dan Johnson || 7 Comments

Taking a welcome break from FAA news, let’s check out our favorite topic: cool new airplanes.

Welcome to the New F2

F2 seen on approach to landing after a pilot report at 2020’s Midwest LSA Expo.

“Wait,” you exclaim! “F2 isn’t new.” Excellent, you’ve been keeping up.

What you don’t know is that Flight Design’s latest and greatest just earned FAA acceptance, winning a Special Airworthiness certificate as the latest Special LSA to enter the market.

Announcing Number 156 on our SLSA List.

Flight Design put years into this thorough evolution of their market-leading model and it has so many new qualities, we present two videos below trying to tell you about all of them.

Now Available as a
Ready-to-Fly Special LSA

“On July 8th, 2021 in Tulsa, Oklahoma, the first production Flight Design F2-LSA to reach the USA was inspected by an FAA representative and issued a certificate of airworthiness as a Special Light Sport Aircraft,” beamed Flight Design USA leader Tom Peghiny. “The aircraft is owned by a gentleman from the Milwaukee area and will be delivered this month at EAA AirVenture Oshkosh 2021,” he added.

Flight Design has elected an entire Garmin suite of avionics. See the first video below for more on F2’s redesigned panel.

“We were very happy to take part in this review. We’ve been waiting for nearly two years”, said Tom Gutmann Jr. of Airtime Aviation, identifying some of the challenges the globe experience over the last year and a half. “We are excited to receive the first F2-LSA in the USA and we are very impressed by the improvements made by Flight Design.” 

“The Special LSA version of F2 is the new high-end edition of the existing line of Flight Design aircraft, complementing the popular CTLS and CT-Super Sport models also sold in the USA,” reported Peghiny. The very popular CTLSi and more affordable SuperSport remain in production and are actively being delivered.

“This is an important day for our company, our customers and our dealers,” said Peghiny. “While F Series is a big step up for Flight Design, this just the first of many F-series airplanes that will come to the USA.”

He clarified that the Flight Design F-series of aircraft include the F2-LSA; the F2-UL, which is a German Ultralight; the F2 CS-23, a certified version that is currently being reviewed by EASA in Europe; and soon, the F4 which is the four-place version of F-series. An electric model, F2e, is also in development.

F2’s throttle handle does double duty: forward to go; backward of a neutral detent for braking. Keep your hand where it belongs.

“The First Article Inspection by the FAA is a review of the documentation provided by a manufacturer to show compliance to the applicable FARs and the ASTM standards used for a particular Light-Sport model,” Tom finished.

FAA has the option perform a full audit or other inspections such as they first-article inspection. Since the German manufacturer has approved so many models and has a long track record with the FAA (and other government agencies), the American regulator deemed a first-article inspection was satisfactory to accept the new model. (Note that new Special LSA are not technically “certified.” FAA prefers to call the process “acceptance.”)

With Flight Design’s F-series family of models, it appears the German designer and producer is taking square aim at the Light Personal Aircraft category FAA has proposed in its new regulation. One piece of evidence: check out the carvernous aft cabin of F2.

Here are two videos further explaining the F-series from Flight Design, focused on the new F2 SLSA:

FAA’s Big Stumble — While the Debate Rages, Students Don’t Get Trained

By Roy Beisswenger || 17 Comments

UPDATE 7/8/21 — BREAKING NEWS:

EAA issued a report today saying FAA took some steps to resolve this matter, but it is far from an elegant solution and does not fully address the problem. You can get a lot from Pelton’s concluding remark but I urge reading the whole article. ••• This thing is far from over, I suspect.

Here’s what Jack wrote, “This entire episode is a scary example of how new interpretations of the regulations can upend the entire community. While this short-term fix allows operations to continue, it never should have come to this point. Creating more than 30,000 new LODAs and exemptions is a paperwork exercise that does nothing to advance safety.”

A most worrisome thing happened recently and it definitely fired up journalists in cyberspace.

Conflict in the skies? A court’s ruling could have an enormous impact on warbirds and Light-Sport Aircraft such as powered parachutes.

FAA’s Orlando Flight Standards District Office took an organization called Warbirds Adventures to court over them charging students they were instructing in a Curtiss P-40 Warhawk.

“That doesn’t affect me,” you might say. Don’t be too sure.

FAA’s regulatory enforcement action “has left CFIs confused and at risk from the greater future liability of ‘flying for hire,’ along with potential regulatory and medical consequences,” reported SAFE, a flight instructor group. “Needless to say, this case has cause a firestorm in the aviation media.”

Flying magazine reported, “[According to a] 1995 Fretwell FAA Legal Interpretation, the trainee is compensating the instructor not for piloting the aircraft, but for the instruction they are providing.”

However, Flying continued, “FAA is now essentially arguing that, for regulatory purposes, ‘paying-passenger’ carriage is exactly what flight instructors are doing every time they take a student into the air for a lesson.”

The magazine concluded (correctly, in my opinion), “If paid flight instruction is now considered ‘carriage of persons for compensation or hire,’ an entire sector of flight instructor licensure — the sport pilot flight instructor — has now been rendered null and void.” … “The recent decision in [the legal case of] Warbird Adventures has the potential to drastically change the foundation of aviation knowledge and safety — flight instruction — as we know it.”

“This departs from the long-standing premise that the compensation a flight instructor receives for instruction is not compensation for piloting the aircraft, but rather is compensation for the instruction,” concurred Justine Harrison, AOPA’s general counsel.

EAA also senses danger, writing, “[An] overly broadly worded ruling by the court could interfere with the right of Limited Category and Experimental Category owners to receive training in their own aircraft. While hiring such aircraft for training has usually been conducted via exemption or LODA, owners and operators have always been able to pay instructors to fly in their own aircraft.”

That may now change, and here’s something none of the other articles touched upon: insurance. When the insurance industry gets wind of this (as they already have according to one account), they may refuse to provide insurance for compensated training by a CFI-S in a LSA. Beyond FAA’s action, a lack of insurance could close down many flight instruction operations.

My FAA advocacy partner Roy Beisswenger (Powered Sport Flying magazine publisher and EasyFlight YouTube channel personality) wrote a spot-on editorial on the subject. I urge you to read his words carefully. —DJ

Training Really Is for Hire

An interesting thing happened on the way to federal court.

Instructors are blown away by the potential disruptions the court ruling may trigger.

The FAA wanted to make sure that a warbird training operation went through some special hoops in order to train in warbirds. The training operation refused. The FAA took the company to court arguing that under 14 C.F.R § 91.315, “[n]o person may operate a limited category civil aircraft carrying persons or property for compensation or hire.” And since the aircraft in question is a limited category aircraft, it could not be operated for training. 

The Court of Appeals agreed and stated that, “the aircraft is not certified for paid flight instruction and substantial evidence supports the order.” 

And then they said “Instead, Warbird argues that § 91.315 does not prohibit paid flight training. We disagree. A flight student is a “person.” Id. § 91.315; see also id. § 1.1. When a student is learning to fly in an airplane, the student is “carr[ied].” Id. § 91.315. And when the student is paying for the instruction, the student is being carried “for compensation.” Id.

Hmmm… Gotta hate it when judges use logic and stuff.

But, here’s the problem.

You see, for years, the FAA has kind of wanted things both ways. 

On the pilot side, the FAA has said that flight instruction isn’t a compensation or for hire activity. The reason for this is that they know in order for a pilot to receive compensation, they have to have a Commercial Pilot Certificate and a current 2nd Class Medical. The way the regulations work, all GA flight instructors need a Commercial Pilot Certificate in order to qualify initially for a Flight Instructor Certificate, but many didn’t want or weren’t able to maintain a 2nd Class Medical to just instruct.

Yet on the aircraft side, the FAA says that certain aircraft can’t be flown for flight instruction for compensation or hire… well at least not without special permission from the FAA in the form of a Letter of Deviation Authority or LODA.

This ruling creates all kinds of problems for flight instructors wanting to provide training to students who own their own experimental, limited category, and primary category aircraft. The big aircraft organizations are pointing this out to the FAA and are beginning the fight to correct this.

But what about Sport Pilot Flight Instructors (CFI-S)? Sport Pilot Flight Instructors are often simply Sport Pilots with the additional Sport CFI certificate. No Commercial Pilot Certificate. No 1st, 2nd, or 3rd Class Medical at all.

And the FAA is very strict about whether Sport Pilots can fly for “compensation or hire.” They can’t. The FAA makes that abundantly clear in the regulations. How’s this for making things painfully obvious?

§61.315   What are the privileges and limits of my Sport Pilot certificate?

(c) You may not act as pilot in command of a Light-Sport Aircraft:

(1) That is carrying a passenger or property for compensation or hire.

(2) For compensation or hire.

(3) In furtherance of a business.

Did the FAA expect to win a ruling that said that flight instruction is “carrying a passenger for compensation or hire” and thereby shut down the entire Sport Pilot flight instruction industry? I don’t think so, but it sure looks like that is exactly what might have happened.

It seems to get worse, too. Does this ruling mean that the best of the GA flight instructors, those seasoned instructors who don’t have 2nd Class Medicals anymore are out of business, too?

It seems to me that the FAA discharged its weapon at its own foot. Give those attorneys a bonus.

Now there is a solution. At least for the FAA’s Sport Pilot problem. LAMA and USUA have written the FAA and proposed additional language to both the GA flight instructor regulations and the Sport Pilot flight instructor regulations. It’s really pretty simple. We just want the FAA to include language saying that flight instructors have the privilege of providing flight instruction “for compensation or hire.”

Pretty simple, huh? 

Maybe it’s too simple.

Of course, there was a little more to the letter, but not that much more.

In the meantime, should Sport Pilot flight instructors stop instructing? I don’t see any evidence that the FAA is going to shut down flight instruction immediately. I look at this as a legal stitch that needs correcting and that the FAA will be motivated to correct. So for now, I personally intend to continue to flight instruct for compensation or hire. At least until the FAA says I can’t anymore.

Enjoy the summer and get your flight instruction while you can!

UPDATE 7/8/21 — BREAKING NEWS: EAA issued a report today saying FAA took some steps to resolve this matter, but it is far from an elegant solution and does not fully address the problem. You can get a lot from Pelton’s concluding remark but I urge reading the whole article. ••• This thing is far from over, I suspect. Here’s what Jack wrote, “This entire episode is a scary example of how new interpretations of the regulations can upend the entire community. While this short-term fix allows operations to continue, it never should have come to this point. Creating more than 30,000 new LODAs and exemptions is a paperwork exercise that does nothing to advance safety.” A most worrisome thing happened recently and it definitely fired up journalists in cyberspace. FAA’s Orlando Flight Standards District Office took an organization called Warbirds Adventures to court over them charging students they were instructing in a Curtiss P-40 Warhawk.

A Threat? Yes, Possibly! Density Altitude Commands Your Respect

By Paul Hamilton || 4 Comments

Normally, this website focuses tightly on airplanes and the equipment and services needed to keep them flying. However, on regular occasions, I receive questions about density altitude and light aircraft. A surprising number believe LSA perform less well than legacy airplanes in these conditions. (They’re wrong.)

Since I also hear questions regarding techniques to fly in mountains, why not combine these two challenges? This information can be useful to anyone who flies any kind of aircraft anywhere in the world.

To provide the best information, I went to an expert. I know a thing or two about airplanes but Paul Hamilton, founder of the Sport Aviation Center, is an expert trainer, not only writing and making videos on the subject for years but regularly providing flight instruction. Further demonstrating his versatility he does so in three-axis and weight shift.

I asked Paul to compose a short lesson about density altitude and he quickly complied. —DJ

Hot days at high elevations with a full load means you need much more runway.

It was a hot day (80 degrees Fahrenheit) at Lake Tahoe Airport (6,268 feet MSL). The airplane was loaded with a big guy (who reported 250 pounds) and nearly full fuel. We had a light tailwind because the airport has rising terrain to the south and we needed to take off to the north over flat terrain towards the lake.

Applying full throttle, we began moving down the runway …rolling, rolling, rolling. It felt like eternity to accelerate and finally lift off and we were going way faster over the ground while climbing sluggishly over the marshland to the lake.

Three of the basic performance problems which have led many General Aviation aircraft accidents were present here: 

  • High density altitude
  • Max gross weight
  • Tailwind

Mountains and high density altitude demand your attention.

The LSA we were using performed great, but revealed a big difference in performance compared to sea level flying. Let’s break this down into the components and look at why this Nevada attempt took so long to take off. 

FAA’s definition for density altitude:

  • “Pressure altitude corrected for temperature and humidity.”
  • Common sense definition – “less air” (density) resulting in reduced engine power plus faster takeoff, stall and landing speeds — because true air speed goes up.

Starting with the FAA definition, pressure altitude is found by setting the altimeter to 29.92 inches of mercury (standard pressure) and reading the resulting “pressure altitude” on the altimeter. Low barometric pressure, less air above you, results in higher (less dense) pressure altitude. High barometric pressure, more air above you, results in a lower (more dense) pressure altitude.

Pressure Altitude Chart

From the well-known FAA diagram (pressure altitude) we can see that with higher barometric pressure you could lower your pressure altitude by by up to 1,000 feet or so, from 6,500 to 5,500. Falling pressure raises your density altitude by up to 2,000 feet 6,500 to 8,500. Typically, it would be less but for calculation expect atmospheric pressure could raise or lower your standard temperature altitude by 500 feet.

Now let’s look at temperature. Standard temperature for 6,500 altitude is about 37 degrees F. If we have a hot day say 80 degrees F, the pressure altitude is 6,500 feet, but density altitude goes up to 9,500 feet. Note that variations in temperature can cause the density altitude to go up 3,500 feet altitude and pressure altitude only 500 feet variation. Temperature makes a much bigger difference in density altitude.

You can use any app, the classic E6B computer, or an electronic E6B to find density altitude. You can also listen to the AWOS; you have various ways to determine density altitude.

Now, how does density altitude affect performance? Let’s start with the rule of thumb I teach and use as a basic for density altitude performance. Take this with you.

At 8,000 feet density altitude, it takes about twice as long to lift off as it does from sea level.  

This is derived from various performance parameters, and it could be 7,000 foot density altitude but 8,000 feet is a good round number for this rule of thumb. 

Temperature and Density Altitude Chart

Why is this?

First, for every 1,000 feet increase in density altitude, the engine loses about 3% power or thrust. So at 8,000 feet density the 100 horse engine is only producing 76% of the thrust, a 24% loss of thrust.

Second, if you rotate at 60 knots indicated airspeed at sea level, then at 8,000 foot density altitude your true airspeed (ground speed in calm air), rotation speed would be 68 knots. Keep in mind your visual reference to the ground speed for takeoff and landing is going to go up 13%. This is why people tend to stall during takeoff and landing, because they feel they are going faster than they normally do. Indicated airspeed, not true airspeed, is what counts in stall.

Therefore, at 8,000 foot density altitude you have 24% less thrust and must get going 13% faster to rotate. All that weight and mass has to gain that much more momentum with significantly less engine power. Loose/loose or bad/bad situation.

Now look at climb rate, your ability to get away from the earth. A 1,000 foot density altitude decreases climb rate by 8%. An 8,000 foot density altitude reduces climb rate by over 60%.

The Koch Chart is the classic many use to determine performance and a well known standard. General aviation aircraft typically have great performance tables and graphs, but LSA and even more so, ultralights, may come with rather basic performance guidance so this Koch Chart is a great tool.

Let’s go back to my original example and use the rule of thumb  with the density altitude of 9,500 feet MSL, plus that tail wind of 10%. Takeoff speed will increase takeoff roll by 20% to the density altitude factor. Now you have just under three times the takeoff roll as you would at sea lever standard conditions. In such conditions, you will eat up a lot of runway to get off the ground.

Light-Sport Aircraft typically have good performance at high density altitudes because with the typical 100 horsepower and max gross weight or 1,320 pounds the power-to-weight ratio is better than larger, heavier aircraft.

Paul’s Experience with LSA

My 1,000 pound weight-shift control trike and Sling 2 at 1,320 pounds, both with the 100 horsepower Rotax 912iS fuel-injected engine are getting 300 FPM climb at 12,000 foot density altitude, which I typically fly in the mountains. No problem taking off at South Lake Tahoe airport but the increase in takeoff roll is noticeable. The carbureted engine performs almost as good with automatic mixture control. 

Giving lessons in the Evolution Aircraft Revo over mountainous terrain.

I have had a number of people who are thinking about buying a LSA with a 100 horsepower engine who are worried about LSA and density altitude. We go flying and they are really impressed with the performance as we cross the mountains at 10,000 feet (12,000 foot density altitude) and land/takeoff at South Lake Tahoe airport (TVL).

The high-drag Quicksilver with a Rotax 582 (65 horsepower at sea level) barely climbs at Carson Airport 4,700 pressure altitude with 7,000 foot density altitude; it has only 100 FPM climb, not enough to climb out depending on other conditions such as convective lift. 

Ultralights typically do not have that much power to begin with so they also do not climb the best at high density altitudes. You can look at performance at sea level for a guide to how an aircraft will perform at high density altitudes

Paul and Loretta Hamilton enjoy the beautiful area around their home base, flying in a The Airplane Factory Sling 2 LSA.

Overall, you need to take the performance at sea level standard conditions, which the manufacturer typically provides optimum pilot and light weight conditions, and look at the density altitude or Koch chart to determine the performance of your LSA or Ultralight.

The recipe to disaster is the airplane that flies up from sea level to South Lake Tahoe in the cooler morning. Headed home by afternoon, they load family, luggage and fuel. In the heat of the afternoon the airplane easily stalls on takeoff or climbout. Remember, they were facing — high density altitude (high elevation plus heat), were likely near max gross weight, and had a tailwind.

Don’t be that pilot. Density Altitude is a condition to be considered seriously.

An accomplished photographer and videographer for years, Paul captures some marvelous views. In this striking image, a Sierra wave cloud is forming. For years, sailplane pilots have used wave formations to soar to amazing heights (flying the lifting leading edge of the wave).

Electric Record UPDATE — Record Set, Trek Continues…

By Dan Johnson || 9 Comments

“WE DID IT!” boasted the team from down under!

“We are thrilled to announce that this afternoon we achieved a World Endurance Record for an electric aircraft, breaking the previous mark set in Germany last year.” (Note: Official recognition always takes more time.)

Pipistrel distributor Michael Coates, wrote, “South Australian-based Eyre to There Aviation … Flying a Pipistrel Alpha Electro plane, arrived in Port Augusta late yesterday (Friday June 25) after breaking the previous mark of 750 kilometers on the leg between Shoalwater Point Station and Whyalla.”

Lead by Eyre to There Aviation Managing Director, Barrie Rogers, the team will continue to Adelaide aiming to fly 1,350 kilometers by the end of the journey.

More than Distance

“Along the way, the team has also broken other world records for electric aircraft,” Coates reported, “including longest over-water flight (30.8 kilometers); furthest distance in a 24-hour period (330 kilometers); and fastest speed between waypoints (177 kilometers per hour ground speed).”

Barrie reported he and his team battled strong winds and rain as well as below zero morning temperatures to achieve the record. (Australian’s seasons are roughly reversed from America’s; this is not summer in Australia.)

“It’s been a mammoth effort by everyone involved to achieve this incredible feat,” Barrie said. “The weather hasn’t exactly been on our side. We had ice on the wings one morning and were grounded in Port Lincoln due to an intense low pressure system.” One of the criticisms leveled at battery power is a loss of energy in cold conditions so the Eyre to There has been doing additional proving of the propulsion concept.

“On the plus side, the aircraft and the recharging systems have held up incredibly well, said Barrie. “It has gone a long way to proving the endurance and reliability of the Pipistrel Alpha Electro plane.”

“Because we can only fly about 125 kilometers (78 miles) before having to recharge, we’ve been landing in some pretty remote locations.”

As reported earlier, Barrie said Pipistrel Alpha Electro is the first and only serially-produced electric aircraft currently approved in Australia for flight training by the Civil Aviation Safety Authority (Australia’s FAA counterpart).

Showing off some of the sponsors that supported the flight, lead by AvPlan EFB and Aerometrex.

“This record attempt will further demonstrate the overall viability of this aircraft,” Barrie added. “Electric aircraft are cheaper to buy, cheaper to run, significantly quieter and don’t rely on fossil fuels. They are ideally suited for short range flight training activities.”

Eyre to There Aviation anticipates one day setting up an assembly line of Alpha Electros in Adelaide producing up to 40 aircraft per year, Barrie said.

The team will continue but from here forward, with one record claim in its logbook, Electro will be adding to its achievements.

You can follow the flight on Eyre to There Aviation’s Facebook page.

Warp Speed! — Designer Alberto Porto Says, “Make It So” with Risen SuperVeloce

By Dan Johnson || 3 Comments

Most of us would be mighty pleased to sit comfortably and gaze upon our pace-setting aircraft. As reported recently, Alberto Porto, head of Porto Aviation, flew to a higher altitude and managed to squeak past the 400 kilometer per hour (true airspeed) barrier in his supersleek Risen powered by the turbocharged Rotax 914 engine.

Most of us, however, are not Alberto. Apparently, this man does not care to sit idly and admire his past achievements.

When you’ve already designed what may be the fastest LSA-type aircraft in the world, what do you do next?

Shorten Risen’s wing span, install a more powerful engine and go even faster. Duh!

Original Risen wingspan: 29.5 feet — Risen SuperVeloce wingspan: 26.9 feet. How much difference results when span loses 31 inches and power increases 40%? Speed demons want to know.

Can LSA Fly So Fast?

The speed olympics are going on in Europe where authorities do not restrict the velocity of what they call “ultralights” or “microlights.” In the USA, very similar models are called Light-Sport Aircraft, except LSA are trapped by that darn 120 knot speed limit.

It’s worth noting several countries that accept ASTM standards do not limit speed. That’s why ASTM created standards for retracts, adjustable props, and other developments that are not presently permitted in America. (The organization is now called ASTM International for that precise reason.)

Are U.S.-based LSA genuinely limited to 120 knots? Yes, and no.

While this may change in the regulation to come at the end of 2023, present-day American LSA are limited to a maximum of 120 knots in level flight at sea level. Most pilots are aware that indicated speeds translate to higher numbers at, say, 10,000 feet above sea level. Some LSA are advertised as capable of reaching 150 knots at high altitude …and that is perfectly okay.

An original “long wing” Risen making a low pass, gear up.

So, if you make the airplane as clean and slick as possible with a speed wing design and if you use retractable gear and in-flight adjustable prop plus install the highest horsepower engine in the Rotax line, you might fly well beyond 140 knots at altitude (150 knots is 278 kph).

Creator Alberto Porto went up high with the original Risen fitted with a turbocharged Rotax 914 and was able to reach 400.45 kilometers per hour or 216 knots. Most of us would be pleased to hit such a number. Most of us might rest on our laurels but Alberto is not most of us.

Re-Inventing Risen

Take that same speed demon Risen and clip its wings and tail slightly while fitting a 141-horsepower Rotax 915iS turbocharged, intercooled engine. What to expect?

“Risen powered with the Rotax 914 turbo for the first time passed the barrier of 400 kph (249 mph) on a 15 kilometer straight course and 379 kph (235 mph) on a 50-kilometer triangle. Truly spectacular especially with a 115 horsepower engine. Just imagine what would happen with a 915iS?” asked Commercial Director, Stéphan D’haene in the fall of 2020.

“As Porto Aviation, we don’t believe you can just install a 40% more powerful engine in the same airframe,” continued Stéphan. “Either your 100 horsepower version is underpowered, or [an airframe with a] 141 horsepower 915iS will be overpowered. This is just physics. Exceptions are, of course, STOL or other draggy designs that will see only a relative small increase of cruise speed due to drag. Risen has the lowest drag ratio in the industry, so adding 40% more power is a lot for an already-fast aircraft.”

Contrasted to many LSA, SuperVeloce looks like you could reach out of the cockpit and touch the wing tips.

Stéphan also commented on changes in European regulations that permit a higher stall speed. As FAA also appears headed toward higher stall, Alberto looks like a visionary in clipping Risen’s wings a bit.

“As the LTF-UL2019 certification standard for 600 kilogram Ultralights no longer limits the stall speed to 65 kilometers per hour, but a significantly higher 80 kilometers per hour, Alberto decided to leverage the real potential of the magnificent Rotax 915iS,” wrote Stéphan. “The airframe received a set of shorter wings and as a consequence, also the oversized Risen V-tail was reduced for perfect balance. This version of the Risen deserves its own type name:  Risen 915iS SuperVeloce.”

Then he hinted, “We believe it’s the perfect name for a 450 kilometer per hour (243 knot) max cruise two-seater!”

First Impressions

“I got the opportunity to fly with Alberto in this amazing new version of Risen,” reported Stéphan. Without any hesitation I can confirm that the aircraft flies as easy and straight forward as the original Risen, which remains in production in combination with the 912iS 100 horsepower engine.” He noted the 100 horsepower model offers excellent economy and is a range champion.

“We performed stalls and saw a 10 kilometer per hour or 6 knot increase compared to the normal Risen,” observed Stéphan. “This is great news as it confirms the computer simulations and allows us to stay within European Microlight regulations, too.”

Going fast pays benefits, at least for buyers that have somewhat thicker wallets.

“Let’s not forget Risen has one of the largest cabins on the market with ultimate comfort for those long trips,” added the commercial director. “Our first 12 months of production are already sold out, even though few outside the factory have seen the aircraft.”

Serial production reportedly commenced three months ago. SuperVeloce #2 will soon take its maiden flight.

Stéphan expressed, “Many U.S. pilots want this aircraft. There are going to be a lot of busy builders!”

Care to be among them?

Going the Distance on Battery Power — Record Attempt Reveals the State of Art in Electric Propulsion

By Dan Johnson || Leave a Comment

Does Alpha have the tiny little motor that could?

Article updated 6/22/21 —DJ

That sounds like an old childhood story (“The Little Engine that Could…”) but here we are in the new millennia with electric cars, huge wind farms, vast solar collector projects, biofuels, and more. Subsidies are pouring in to electric projects around the globe. Hundreds of developers building “urban air transport” multicopters are raising millions of dollars.

Will human-flown conventional aircraft join the electric parade? One company has pursued the electric dream further than most.

This story is about a group in Australia that aimed to set a new world record, one of a rather different sort.

photo from YouTube[/caption]“]

In this case the team plans a “record attempt flying a Pipistrel Alpha Electro plane,” Australia and USA Pipistrel dealer Michael Coates wrote. “[The flight] will start at Parafield Airport at 7:00 a.m. on Saturday June 19, 2021.” Total distance, Michael added, will be 1,150 kilometers, which “will shatter the previous record of 750 kilometers flown in September 2020 in Germany.”

This project hopes to break the previous distance by more than 50 percent. Whatever the outcome, many will admire the effort to fly an electric airplane a lengthy distance. How will they handle the “range anxiety” about which we hear so much?

FYI: The two distances — 1,150 and 750 kilometers — equate to 715 and 466 statute miles, respectively.

Team Alpha Goes the Distance

The attempt to set a new record is being led by Eyre to There Aviation Managing Director, Barrie Rogers, who undertook the first ever electric flight in South Australia in 2020.

Pipistrel Alpha Electro, which the down-under gang has dubbed the “Tesla of flying,” currently has a flight time range of about one hour and cruising speed of 85 knots (98 mph or 157 kph). With this in mind, Barrie said, “We’ve had to very carefully plan each stop and build in contingencies for weather such as strong head winds.”

Barrie clarified that the record attempt flight team and support crew “will include three pilots, five on-the-ground support crew, a second support (petrol-powered) plane, and two vehicles carrying recharging equipment for the aircraft.”

While a strong and notable effort, the attempt and the support it requires puts battery-electric propulsion in perspective. Several current, gasoline-powered Light-Sport Aircraft could fly the entire 1,150 kilometer distance on a single tank (or tanks) of fuel without any need to stop and with no support crew.

Let’s be fair: Electric airplanes are relatively new and they will only get better. It is not reasonable to expect them to perform equally with fossil-fuel-powered aircraft that have been developed over many decades and with billions of dollars invested to help them achieve the high state-of-the-art they possess today.

Yet what this observes once again is that batteries are the weak link in the electric propulsion chain. Energy contained in batteries is a small fraction of that contained in a similar volume or weight of gasoline. That gap is narrowing but the pace seems glacial compared to forecasts of electric enthusiasts. Battery improvements of a few percentage points per year means decades before batteries match fossil fuel in energy per pound.

Give batteries some magical breakthrough to equal fossil fuel energy and the betting will end. Electric propulsion will push out fossil engines quickly — but that day is not here now. It may be years in the future.

FAQs About Alpha Electro

Pipistrel Alpha Electro started development in 2014; it was released to the public in 2017. “Electro was an immediate success with more than two-dozen orders after its initial 2017 release,” boasted Slovenia-based Pipistrel. “Electro has been designed as an entry level circuit training aircraft perfect for flight schools,”

How long will the aircraft fly at cruise/cross-country? — Answer: “45 minutes at 18kW (reduced power) and 75 knots indicated airspeed”

How long does it typically take to charge the batteries with different chargers? — Answer: “Six hours with a 3kW charger; an hour forty with 10 kW charger; an hour and five minutes with a 14 kW; or 45 minutes with the 20 kW charger.”

How heavy are the batteries and can I swap them myself? — Answer: “Each battery pack is 53 kg (117 pounds). Yes, you can remove the pack with no extra help.”

What is the luggage capacity the aircraft? Answer: “There is no luggage compartment. Convenience luggage can be stored in the side pockets on the instrument panel.”

Rotax 915iS Proves a Winner — “Best Powertrain Concept in the Light-Sport Aviation Industry”

By Dan Johnson || 3 Comments

How does modern-day Rotax relate to the Wright Brothers? Here’s a trivia test for light aviation enthusiasts.

Answer:  Both started out in the bicycle business.

A little over a year ago, the engine builder from Gunskirchen, Austria celebrated their 100th anniversary. Check this article that contains a link to a beautifully-presented history of the company. It also describes how the company got its name.

In production for more than 30 years, Rotax’s 9-series engine design was a significant departure from earlier aircraft engines.

The 9-series is physically smaller, uses liquid cooling, an electronic control unit, and a gearbox to change engine revolutions from 5,000 rpm to slower speeds that work for props. The 912 enjoys a much better power-to-weight ratio than familiar models such as Lycoming’s O-233. That veteran engine produces 100 horsepower (at 2300 rpm; higher power is available at increased revolutions) using 233 cubic inches of cylinder displacement. In a sharp comparison Rotax’s 912 ULS makes the same horsepower using only one-third the displacement, 83 cubic inches.

This configuration may not seem so important on larger, heavier airplanes built around such legacy engines. In the world of Light-Sport Aircraft and European-style “ultralights” or microlights, Rotax has delivered a compact, optimized package. It should surprise no one to hear the brand dominates the light aircraft sector with more than 80% of the market.

The Rotax “9-Series”
912—914—912iS—915iS

On June 16, 2021, BRP-Rotax announced “The Rotax 915 iS aircraft engine was awarded best powertrain by the readers of Aerokurier, a leading German aviation magazine.”

Rotax’s certification team celebrates after winning approval for the 915iS engine.

“To be elected by the readers of the magazine proves that we have developed truly the best engine for this market in terms of performance, reliability and ease-of-use,” said Peter Oelsinger, General Manager BRP-Rotax. “Many thanks to the readers for their votes and commitment to our aircraft engines.”

Rotax aircraft engines now number almost 200,000 including both two- and four-stroke powerplants and a global four-stroke 9-series fleet of more than 50,000 engines. Its worldwide network consists of 16 authorized distributors and more than 220 points of sales and service supporting 270 airframe producers that build more than 400 Rotax-powered models worldwide.

Journalists and airframe designers rushed to photograph or examine the 915iS engine after it was introduced at EAA Press Headquarters in summer 2015.

The division assembling Rotax aircraft engines is part of BRP-Rotax GmbH & Co KG, itself a subsidiary of BRP Inc., which develops and manufactures engines for Ski-Doo and Lynx snowmobiles, Sea-Doo watercraft, Can-Am all-terrain, side-by-side vehicles and Can-Am Spyder and Ryker lineup as well for motorcycles, karts, ultra-light and light aircraft.

In the last 50 years, the company has developed more than 350 engine models for recreational vehicles and produced over nine million engines.

BRP also builds propulsion systems for brands such as Alumacraft, Manitou, and Quintrex boats. The company supplies dedicated parts, accessories and apparel. Annual sales total $6 billion (Canadian or U.S. $4.9 billion) generated in more than 130 countries by a global workforce of more than 14,500 people.

SNEAK PREVIEW — In less than 10 days, I will have an announcement regarding how one aircraft may zoom faster than any other LSA. Could it one day eclipse the 500 kilometers per hour barrier (271 knots)? That sounds impossible but so did other records before they were broken. Click or tap back soon!

How does modern-day Rotax relate to the Wright Brothers? Here’s a trivia test for light aviation enthusiasts. Answer:  Both started out in the bicycle business. A little over a year ago, the engine builder from Gunskirchen, Austria celebrated their 100th anniversary. Check this article that contains a link to a beautifully-presented history of the company. It also describes how the company got its name. In production for more than 30 years, Rotax’s 9-series engine design was a significant departure from earlier aircraft engines. The 9-series is physically smaller, uses liquid cooling, an electronic control unit, and a gearbox to change engine revolutions from 5,000 rpm to slower speeds that work for props. The 912 enjoys a much better power-to-weight ratio than familiar models such as Lycoming’s O-233. That veteran engine produces 100 horsepower (at 2300 rpm; higher power is available at increased revolutions) using 233 cubic inches of cylinder displacement.

Family Flying Adventure… AirCam Enthusiasts Flock to Gorgeous Jekyll Island, Georgia.

By Dan Johnson || 1 Comment

“Winds are going to be rather sporty,” observed AirCam developer, Phil Lockwood, as he and Robert Meyer and the AirCam team finalized arrangements for another fly-out, this one to Jekyll Island (09J).

A family that flies together. Son Ian, dad Phil, and mom Tisha flew to Jekyll Island in a three-seat AirCam. The only challenge? They’re all pilots. Who gets to do the flying?   Photo by Ian Lockwood

The single runway near the resort island had a crosswind forecast for arrival day. When it comes from the east, air tumbles down over a tree line to disturb a smooth approach. The air was indeed “sporty.”

I’m an AirCam enthusiast even though I don’t own one. I earned my multi-engine rating in an AirCam some years ago and I’ll take any opportunity to fly one.

Numbering 300 AirCams
(…that’s 600 Rotax engines!)

Many of you know the story by now. AirCam was first developed to fly National Geographic photographers trying to document nature in Namibia. From what I can tell the entire country appears to be one enormous, dense jungle. Where ya gonna land?

Phil to the rescue. After building Drifters for years, Phil had a plan to accomplish what the photographers needed for the beautiful but rather primitive African nation. He designed a potent twin engined airplane that could take off from a tiny field and could position a photographer six feet out in front of the leading edge with an enormous field of unobstructed view.

A three-seat AirCam with full enclosure.

The plan worked perfectly but then a funny thing happened.

Pilots kept saying they wanted one for themselves. Phil and his staff accommodated them and have steadily improved the machine until today, 300 of them fly around the USA and the world. You’ll rarely see a bigger smile than from a pilot who just landed an AirCam.

While some AirCam pilots chose to avoid the bumps at Jekyll on arrival day — flying just a few minutes north to St. Simons airport (SSI) with a runway facing into the wind — all the AirCams were back at Jekyll the next day. Even on that first evening, some of us watched as landing lights switched on when Ian and Robert flew a pair of them back from St. Simons after dark.

AirCam #1 flying in the Congo. See any landing areas? Power came from two Rotax 582s. The aircraft has evolved significantly since.

Since it was late May… since we were in the warm South… and since it’s almost summer, several of the AirCams were mounted atop amphibious floats. Well, why not?

With Twin Rotax 912s (even 915s have been fitted), AirCam can lift off water even with amphibs after a very short, brief water run. Considering an AirCam is capable of taking off from land on one engine (not advised, of course!), jumping off the water with both engines fully spun up is exhilarating.

Leading His Flock

Leading a gaggle of AirCams from Florida, Phil managed the navigation and communications from the middle seat, while son Ian flew up front and wife Tisha spotted traffic from the aft seat. How they decided that seating must be something of a State secret since all three are pilots.

Robert Meyer checked out a pilot who prepared to fly this amphibious AirCam.

The Lockwoods flew in tandem seating — one behind the other — in a Generation Three or “Gen 3” AirCam with the clamshell enclosure (photo). Occupying the aft seat, Tisha reported an abundance of room. AirCam may not look it, but the aircraft is surprisingly spacious.

Using the Whole Runway

Back to Phil’s “sporty” air. His forecast was no understatement. My flight from Spruce Creek near Daytona Beach, Florida to Jekyll took only about an hour. We flew over the ocean (within an easy glide distance from shore) where it was was smooth and effortless. Yet once we arrived near Jekyll and dropped down to pattern altitude the mechanical turbulence from air spilling over the tree-filled island added lots of bumps to the air.

“It’s doesn’t feel that bad,” I told Randee. “I think a landing is doable.”

Once we descended below 300 feet, that gusty air made final approach feel like a roller coaster ride. Woo-hoo!

I decided to keep my speed up and leave the flaps retracted to facilitate an abort if it proved too rough. I was prepared to use the majority of the long, paved runway… and I did. Yet we got down. We flew in a Van’s RV-12 to which I have access and, like all RVs, the handling is superb. I was sure I would not run out of control authority.

With quite a few hours logged in AirCam, I think it could have handled the winds, but such a decision is about pilot skill and experience, not the aircraft or its controls. Phil made a prudent decision to lead his formation four more miles to St. Simons. Not only was the runway better wind-oriented but the airport area is more open with few nearby obstructions.

As the weekend unfolded, the winds died down and Jekyll proved as fetching a place as ever. I tell you what: these AirCam people know where to take their powerful birds for a good time. Learn lots more about AirCam — maybe you can join the next outing.

In this video, LSA expert John Hurst describes his experience flying an AirCam with two 912iS fuel-injected engines from Sebring, Florida to Oshkosh, Wisconsin.

LSA Update — Finland’s ATOL Avion… Ekolot Topaz Wins Another… Fresh SW-51 Video… New FAA Reg Update Video

By Dan Johnson || 2 Comments

Summer is fast approaching and for much of the northern hemisphere, that means seaplane flying. For all pilots, covid fear is dissipating and summer skies beckon.

In this LSA Update…

  1. Learn about the return of Finland’s wood-and-composite LSA seaplane, now rebadged as Avion from new supplier Scandinavian Seaplanes (updated 6/15/21)
  2. Check out another award for Ekolot’s handsome and deluxe Topaz
  3. See a very fresh video of the impressive ScaleWings SW-51 in flight
  4. Watch a video version of our recent FAA regulation update on Mosaic

As the globe slowly emerges from the dark cloud that was Covid, the light aviation industry is doing admirably to move forward with developments and improvements.

Come along for the read — check out these stories.

Atol is Back …with Avion

According to main man Anssi Rekula, “Finland is a true [paradise] of seaplane flying with 188,000 lakes, 45,000 miles of river and 4,000 miles of seafront.” That is surprisingly similar to the United States even though America is 29 times larger by area.

A new enterprise bought all rights and assests from bankruptcy estate of Atol Avion Oy, which filed for bankruptcy on February 2, 2021.

Scandinavian Seaplanes Oy was formed by two Swedish investors Andreas Svensson and Oskar Samuelsson together with Anssi, a co-founder of Atol Avion.

The Samuelssons are both business people. Their new aviation company will also design and manufacture aerospace parts and components to order, once they have Design Organization Approval and Production Organization Approval from EASA.

Rekula has extensive aviation experience from being a Coast Guard helicopter maintenance officer to flying for Finnair airlines as a Captain. He has 10 years history with Atol Avion and Aurora.

Aurora, a two-seat amphibian, has been under development for nine years. Scandinavian Seaplanes forecasts serial production will start by the end of Q2 2022. A core team familiar with Atol Avion has been hired to work for company and this will enable the official transfer of the nearly finished type certification project with EASA (European Aviation Safety Agency, the Union’s counterpart to FAA).

Building airplanes at the Halli airport in Jämsä, Finland, a facility with a long aviation tradition. Scandinavian Seaplanes aims to be profitable latest 2023 stating that the Halli facilities can manufacture 20-30 planes per year. They will concentrate mainly in assembly, while most parts are made by a chain of audited nearby subcontractors. We have been negotiating with the city of Jämsä since the beginning of the year says Anssi Rekula, CEO of Scandinavian Seaplanes.

Jämsä Mayor Anna-Liisa Juurinen said, “The new arrival will strengthen the aviation industry in the area. Halli airport, nearby lakes, and new aviation-related partners motivated Scandinavian Seaplanes to locate in Jämsä,” Juurinen added.

The somewhat faster Saab Draken is also built in the area.

“Each component of the renewed Aurora has been optimized through design and selection of materials which include carbon fiber, aluminum, Kevlar and wood-composites,” explained Anssi. “This material optimization helps Aurora lead the light seaplane industry with 595-pound useful load without compromising strength and durability.”

Scandinavian Seaplanes is proud Aurora uses what some might call an antiquated construction material: wood. Anssi noted, “In today’s environmentally-conscious world one of the nicest features of the wooden structure is its small carbon footprint, which is about 65% less compared to other construction types. Wood binds carbon, whereas the manufacture of aluminium and reinforced plastic materials and carbon fiber release it.”

Flight training will be a part of ”one-stop” customer service from Scandinavian Seaplanes, as buyers will be offered training for type and seaplane ratings plus the Private Pilot License.

Topaz Wins Another Award

Today, many LSA have become quite deluxe with fancier interiors and better avionics. However, Ekolot was ahead in this upgrade game.

The Polish company’s top-of-the-line Topaz is a striking machine outside and inside with its automotive-styled, leather-trimmed interior and nicely-achieved features.

Ekolot has experience with sailplanes and the composite finish shows a glider producer’s attention to an exceptionally smooth finish.

Get factory tech specs (metric) but the U.S. translation is: wing span 35.3 feet; wing area 109 square feet; gross weight 1,232 pounds (the first weight FAA chose for LSA; later updated to 1,320); empty weight 639 pounds, meaning Topaz has a useful load of 593 pounds and a payload with full fuel of 485 pounds; fuel 18 gallons, cruise 123 mph (107 knots); climb 1,575 fpm; stall 34 mph.

Standard power is supplied by Rotax 912 swinging a three-blade composite prop. It is sold standard with an whole-airframe emergency parachute.

At Sun ‘n Fun 2021, importer Krzysztof “Kris” Siuba collected another trophy for his office shelf as Topaz won the “Outstanding Factory-Built Fixed Wing Light-Sport Aircraft” category.

Hopefully, Kris and Topaz are not “tired of winning” as a well-known politician once predicted.

Here’s fresh video of the SW-51 conducting its first flight — lots of good images, courtesy of the factory:

Flight Design Introduces CTLS GT with Rotax 914 Turbo Power

By Dan Johnson || 8 Comments

Recently I interacted with a reader, someone considering a light aircraft for purchase. He inquired about the ability of ultralights or Light-Sport Aircraft to cope with high density altitude. He raised valid and worthy points but showed a certain lack of knowledge about the capabilities of light aircraft. (We are working on a more detailed article on this subject.)

Here’s the simple response: light aircraft with modern (read: powerful and efficient) engines tend to perform admirably well in high elevations, higher heat, and high humidity. If you fly almost any of these aircraft in high density conditions you already know they perform sprightly.

In contrast, I logged hundreds of Cessna 150 hours from my days as a flight instructor, and — with a similar amount of power as most LSA but also quite a few more pounds — that aircraft definitely does not perform as energetically.

So, a higher power-to-weight ratio is good, but do limits exist?

Welcome to CTLS GT 914T

“Flight Design is pleased to announce the availability of the 914T option for the CTLS GT 2020,” the German company announced today. “CTLS GT with the turbocharged Rotax 914 plus a large intercooler greatly improves the climb rate, cruise speed and high-altitude performance on Flight Design’s most popular model.”

CTLS has long been the leader in the American LSA fleet. While the company has also announced their F-series, CTLS remains a key model for the company. The CT-series already fits regulations in many countries.

“We are very excited to finish development of this new variant of the CTLS GT,” said Daniel Guenther, managing director of Flight Design general aviation. “The design team did a beautiful job integrating the Rotax 914 with the turbocharger and intercooler into the new longer cowling of the CTLS GT 2020. From the large NACA inlet (photo) and the custom welded aluminum piping, the engine compartment is just a thing of beauty,” said Daniel.

CTLS GT Turbo incorporates all the new features of the GT 2020 model including the longer, more attractive cowling with improved cooling and cabin heating, new prop spinner, and new low drag wheel pants for improved performance. Equipped with a full Garmin avionics suite including dual G3X screens, the CTLS GT is a thoroughly modern aircraft that can reach 140 knots (TAS at altitude) and can climb at better than 2,000 feet per minute.

“I was very impressed with the performance of the CTLS GT with the Rotax 914 Turbo,” said Flight Design test pilot Nico Stambula. “CTLS GT Turbo climbs like a rocket and easily reaches 140 knots at altitude.” Stambula added that the 914 intercooled engine maintains consistent temperatures. In addition, this is a very smooth flying package.”

The first CTLS GT will be shipped to an owner in South Africa, which has both high temperatures and high elevations. Flight Design believes the new model “should be just great for operating in those more challenging conditions.”

With the addition of the Rotax 914T option, the long-running CTLS extends its range again. Various models are available as a European 600 kilogram (European) Ultralight, an ASTM-compliant Special LSA, or as an EASA-certified aircraft. Models are available with the Rotax 912, the 912iS and now as a turbocharged performer as the CTLS GT 914T.

“What? No Rotax 915?”

Someone was bound to ask why engineers didn’t use the newest 141-horsepower Rotax 915 iS, so I queried the company on this question.

Since the start of Light-Sport Aircraft, Flight Design has been represented in America by Tom Peghiny, proprietor of Flight Design USA. He’s everyone’s go-to guy for all things CT.

“Flight Design chose the Rotax 914 Turbo for the CTLS 2020 GT airframe for several reasons:

  • “Engine weight and size were perfect for the CTLS airframe with no structural modifications required to the existing airframe.
  • “Top speed at altitude was also within the existing CTLS limits, so no long test flight program was required to make the 2020 GT turbocharged variant.
  • “Because the 914 has a similar configuration to the often-installed 912ULS and 912iS, no major firewall-forward changes were needed to fit a 915.”

Tom added that he is gearing up for the company’s display at EAA AirVenture Oshkosh 2021 where he will lead the announcement of other Flight Design products; aircraft will be on exhibit in space 94.

Here’s a review of the CTLSi with the 912iS engine. Most of the video regards the airframe that remains the same on the CTLS GT 914T.

Airborne at Last — Scalewings’ Intricate and Spectacular SW-51 Achieves First Flight

By Dan Johnson || 8 Comments

This flying dream has been years in the making. Admittedly, it’s a big project, but so authentic is this 70%-scale P-51 Mustang lookalike that I think I see you already starting to drool.

Don’t feel too conspicuous. It’s happening to me, too, along with nearly everyone else. [Article updated on 6/4/21 regarding price information; see below. —DJ]

Of the many thousands of airplane designs created since Orville and Wilbur made their first flight 118 years ago, North American’s muscular Mustang consistently ranks as the most-admired flying machine.

You probably can’t afford an original (or even the maintenance it takes to keep one flying) but you might be tempted by this fantastic carbon fiber vision from Euro developer, ScaleWings AeroGroup and its ultra-energetic designer, Hans Schoeller.

SW-51 Finally Flies!

On May 20th, 2021, SW-51 Mustang successfully performed its first flight at Mlada Boleslav airport (LKMB) in the Czech Republic.

ScaleWings reported, “Aircraft serial number #001 took off at 11:37 am into a light cloudy sky.” The all-important first flight went without problems.

“Chief Test Pilot Jirko ‘Jiri’ Hybler praised the balanced and highly maneuverable handling of the aircraft, managing crosswinds of more than 10 knots with superior control,” continued ScaleWings. “Within the first flight hours all systems were checked to prove their functionality.”

The company reported test flights included cycling up and down of the all-electrically-driven landing gear. First flight went exactly to plan and 35 minutes later, the aircraft landed safely.

“This first flight of the serial aircraft configuration of the SW-51 Mustang is an important milestone for our team,” ScaleWings said.

The SW-51 aircraft program was launched in 2013, followed by a successful first flight of a “proof of concept” prototype just one year later in 2014. Since then ScaleWings has been working on both production processes for the aircraft and preparing the company’s production site in Krosno, Poland.

The ScaleWings SW-51 Mustang is a true-to-scale high performance replica modeled precisely upon the original North American P-51 Mustang aircraft dimension but fully built from carbon fiber.

No question, SW-51 deserves the closest possible examination. This is an amazing construction.

SW-51 is an intricate eye-catcher featuring more than 100,000 details such as simulated rivets, screws, fabric and more that were meticulously handcrafted into the manufacturing molds. Even when you physically touch them, rivets and screw heads feel real. They’re not; it’s a marvelous illusion.

Schoeller’s unique treatment combines with a high quality chrome-like finish, allowing SW-51 to almost-identically mirror the original’s aluminum appeal. Without a doubt, this is an unprecedented execution beyond anything I’ve ever seen.

The aircraft is designed for up to 750 kilograms (1,653 pounds) gross weight, while it is currently being flown in a category limited to 600 kilograms (1,320 pounds) in accordance with prevailing European standards. The numbers show SW-51 could fit nicely into FAA’s proposed Light Personal Aircraft but it could also stay a Light-Sport Aircraft. A fixed gear, fixed pitch prop version has been in discussion for some time.

With first flight in its logbook, ScaleWings said, “We will produce and deliver 5 aircraft in 2021 and 12 aircraft in 2022.”

SW-51’s configuration features a Garmin G3X glass cockpit, electrically driven retractable landing gear (main gear and tail-wheel), ballistic emergency airframe parachute by Galaxy GRS and a brand new Rotax 915iS Turbo engine, catapulting the sleek design to a climb rate of more than 2,200 feet per minute. The airframe’s flight envelope is designed for a Vne of not less than 400 kilometers per hour (216 knots). The good news is noise is far less than on an original P-51 with its huge Roll Royce engine, but a clever “sound system” preserves the imagery and a ’51’s historic ramp appeal.

Updated Info — Some readers were intrigued enough to ask about price. SW-51 is not cheap but at this level of complexity to manufacture, I doubt many readers expected anything different. Here’s what Christian wrote in response to my request, “Depending on the configuration, expect something starting in the range of €240,000 in Europe (about $292,000 at today’s exchange rates). While ScaleWings is not ready to start U.S. deliveries yet, Christian did state that an N-number-registered Experimental Amateur Built version will be offered. —DJ

ScaleWings is a German aircraft design and manufacturing company with offices in Austria and Poland. The company runs its own production plant in the renowned “Aviation Valley” in southeast Poland, where the SW-51 Mustang is built by a workforce of 30 full-time employees in a 25,000 square foot facility. The company reported, “[We] have now entered serial production of the aircraft with a current production output of twelve aircraft per year.

“SW-51 Mustang costs less than 10% to acquire, less than 1% to maintain and it burns less than 15% of the fuel of an original North American P-51 Mustang aircraft. That’s a big savings but this is not an inexpensive kit.

Due to the simplicity of the design ScaleWings stated and its test pilot confirmed SW-51 does not require exceptional pilot credibility, reducing costs of training and operation and costs such as aircraft insurance and annual inspections.

If you, like so many, have dreamed about flying a P-51 (but probably never will), SW-51 might be an answer to prayers.

As Christian concluded, “[SW-51] facilitates the entry for anybody to finally … own and fly a Mustang by him or herself.” Affordable means something different to every individual but this striking light aircraft may encourage you to save all you can.

Here’s my video interview and review of Scalewings SW-51 from Aero 2018. Learn many additional facts from my conversation with Marketing and Sales leader Christian von Kessel and designer Hans Schoeller:

Faster and Faster — Porto Aviation’s Risen Eclipses the 400 Kilometer per Hour Barrier

By Dan Johnson || 3 Comments

The appeal is obvious. What pilot doesn’t like the idea of flying faster? Even those of us who enjoy low-and-slow Part 103 ultralights remain intrigued by the idea of going fast, eating up the miles en route to a destination. [Article updated 5/31/21 with additional information. —DJ]

Alberto Porto put a smile on the face of Troy Jones’ daughter after flying in Italy.

Since I first saw this aircraft when it was unveiled to the world at Aero 2015, I have kept my eye on Risen. It was clear this design was going places… literally.

I used a bit of English humor in the lead photo saying “Risen Shine,” meant to play off “Rise and shine,” a get-out-of-bed-and-get-to-work phrase common in the U.S. The truth is, you don’t pronounce it RYE-sen. Porto Aviation Group marketing man Stéphan D’haene clarified that they say REE-sen.

However you may say the name, Risen is one ripping-fast aircraft. Below you’ll read about its latest speed record but Americans may be interested to hear the first example is now tearing up the skies over Montana.

First in America

At the end of 2020, on December 10th Porto Aviation Group celebrated an accomplishment: “We got the first ‘November’ tail in the air.” They refer to a a Risen with N-numbers on it as the first U.S.-registered model in America.

A family that flies together, visiting Risen at its home airfield.

Their launch customer is a long, tall medical doctor looking for a fast, efficient, and economical commuter and travel aircraft. “Troy Jones was exhausted with long car drives and hotel overnights,” said Porto Aviation. “He preferred to fly his own aircraft so he could get home to his family by end of day.”

Jones stands 6 feet 9 inches so finding an aircraft that could accommodate his tall frame was not easy. After discovering Risen, Troy emailed with designer Alberto Porto subsequently booking a trip to Italy to see if he actually fit.

According to Porto, Risen has “a fully modular cockpit that can be adjusted to any owner requirements.” They believed the sleek aircraft could easily accommodate a pilot of Troy’s height. It did and a purchase was arranged.

In 2019 and early 2020, before Covid, Troy spent time in Italy building his Risen using Porto Aviation’s building-assist program. His family joined him, enjoying the beautiful surroundings of Lake Como and the Italian Alps while Troy worked on his aircraft. Porto is located near the Swiss/Italian border.

Checking out Risen at Porto’s home airfield in northern Italy; gear is shown partially retracted.

As summer 2020 arrived, the building was completed and Porto Aviation finished the task by painting the aircraft and packing it in a standard 20-foot container for shipment to the USA. After long delays related to Covid, Alberto Porto traveled in early December to Lander, Wyoming to be present during the aircraft inspection by a DAR. Giving his first U.S. bird a careful introduction, Alberto provided ground training with Troy and his flight instructor, John Larsen.

Including his 40 hours of flying in a designated area as is common for all Experimental-Amateur Built aircraft, Troy has now logged about 50 hours in the 48-inch-wide speed machine. His Risen is powered by a turbocharged Rotax 914 as Lander airfield (KLND) has a 5,588 foot field elevation. With this engine, his Risen can handle the density altitude well and can hit 200 knots while boasting a typical cruise of 180 knots. Climb exceeds 1,500 feet per minute.

Amplifying its speedy ways, Risen boasts a most impressive 23:1 glide ratio. A shorter wing version is also available.

Troy’s Risen is equipped with a Dynon HDX system combined with Garmin’s latest GPS navigator for IFR compliance. The Italian company also offers a full Garmin suite.

If you are intrigued by Risen but not sure you want the cost, complexity, or maintenance of a retractable-gear aircraft, Porto Aviation offers a fixed-gear version called Siren. Besides stiff-legged gear, Siren uses a simpler split flap system.

400-Kilometer Barrier Falls

Porto Aviation excitedly released this news: “Friday early morning, April 16th 2021, Alberto Porto and Yasemin Arslan van Deursen flew a Risen to 400.45 kilometers per hour (248.8 mph) on a 15-kilometer straight course, a first for any [European] ultralight.

Alberto Porto gives further instruction to instructor John Larsen.

On the same day Porto and van Deursen flew another record: a new all-time high record 378.94 kilometers per hour on a 50-kilometer triangle track.

Staying within European guidelines, the speedy Risen weighed a maximum of 472.5 kilograms (1,042 pounds) and demonstrated stall at less than 65 kilometers per hour or 35 knots). While the Europe-wide EASA now has a 600 kilogram (1,320 pound) class matching international LSA, individual European nations also have the “ultralight” class. In this classification, max weights are 450 kilograms without an emergency airframe parachute or 472.5 kilograms when so equipped; parachutes are mandatory in Germany and other nations accept this safety allowance.

Powered by the same standard 115 horsepower Rotax 914UL engine, Risen was exactly the same ultralight (serial number) that set previous records on December 15th, 2019. The same sponsor stickers still appear on the fuselage.

Troy Jones’ Risen is now N-numbered, based in Montana, and free to fly American skies.

Some give-and-take between producers of speedy light aircraft — reported here — prompted Alberto Porto go show his design’s prowess in a more similar comparison. FAI record attempts are done in multiple categories to accommodate aircraft of many types. Of course, rules exist for each of them but rules are sometimes changed or viewed differently by new judges. Rather than getting caught up in rule writing, Alberto vowed to recover his record.

For technical people, Porto Aviation wrote, “The 2015 Risen 912ULS record (323.84 km/h or 175 knots) was beaten in 2019 by the Risen 914 (337.51 km/h or 182 knots). Both are MSL and ISA and you are comparing apples with apples. It’s a difference in speed that is in line with the increase of horsepower, laws of physics-compliant. Yet, we claim today with the same Risen 914 at FL100 a speed of 400.45 kilometers per hour or 216 knots.”

“Can anyone see us claiming that our Risen 914 is now 62.94 kilometers per hour (34 knots) faster than the same Risen 914,” Porto Aviation asked? “Of course not. It’s still exactly the same aircraft, but at different flight conditions.”

This article explains the record-setting task in more detail. For now, suffice it to say that whatever the records body, FAI, says, Troy Jones’ Risen is one of the fastest light planes in the USA. I’ll bet it won’t be the last.

Porto Aviation is now offering this full Garmin suite in Risen.

The followings video, recorded at Aero 2015, has been viewed more than 600,000 times. The design was new then but it has continued to attract interest. Designer Alberto Porto shows us around his intense speed machine. The company website changed since the video was uploaded. Go here for more.

A few readers asked if Risen uses flaperons. This image shows the answer and further reveals the air-flow efficiency of Fowler flaps plus the compound shape of the leading edge.

The appeal is obvious. What pilot doesn’t like the idea of flying faster? Even those of us who enjoy low-and-slow Part 103 ultralights remain intrigued by the idea of going fast, eating up the miles en route to a destination. [Article updated 5/31/21 with additional information. —DJ] Since I first saw this aircraft when it was unveiled to the world at Aero 2015, I have kept my eye on Risen. It was clear this design was going places… literally. I used a bit of English humor in the lead photo saying “Risen Shine,” meant to play off “Rise and shine,” a get-out-of-bed-and-get-to-work phrase common in the U.S. The truth is, you don’t pronounce it RYE-sen. Porto Aviation Group marketing man Stéphan D’haene clarified that they say REE-sen. However you may say the name, Risen is one ripping-fast aircraft. Below you’ll read about its latest speed record but Americans may be interested to hear the first example is now tearing up the skies over Montana.

Wave Theory — After Years of Thoughtful, Thorough Development, First Flight Is Getting Closer

By Dan Johnson || 2 Comments

Down under, heads are down and wrenches are wrenching. A team in New Zealand has been working for years on what might be the most sophisticated new aircraft to emerge …well, anywhere among Light-Sport Aircraft but certainly in LSA seaplanes.

Look out, Icon A5! Here comes Wave and it should be quite exciting.

Designer Paul Vickers (see video interview below) has a history in boat-hull design. This history forms a logical path to a LSA seaplane with its boat hull and water control features. Paul employed that experience but has widened his history to encompass a flying boat, the Wave.

From the images that accompany this article, you may see a artist’s sense of style, an engineer’s focus on efficiency, and a creator’s close attention to detail. I think these fresh photos convey those qualities quite well.

Visual Clues

We can pick up a few clues from these “teaser photos.” (Somebody appears to know a thing or two about taking intriguing photos.)

In one image you notice the Rotax 915iS hiding inside its shapely engine nacelle.

Over the years, Wave has evaluated different engines. At one time, they contemplated Continental‘s 180-horsepower Titan. That would have provided ample power but uses a heavier construction. Vickers finally settled on the latest 141-horsepower Rotax 915iS that is seeing growing use and enjoys worldwide technical support.

With around 20% more weight than Icon A5 — assuming Vickers uses 100% of their FAA-granted weight exemption — but with 40% more power, Wave may turn out to be a lively performer although the real proof of this will be in the flying. Vickers projects Wave to have a cruise speed close to 120 knots and a climb rate of more than 1,400 feet per minute.

In other images, we see that Vickers is working with MT propellers. This established, higher-end company has been involved with exploratory work on a Searey to implement and test Single Lever Control. As that feature is coming for LSA in 2024, Vickers may be getting ahead in another way by working with MT Props. Add the 915’s higher power to the efficiency of an adjustable prop and Wave’s performance advantage may stretch further. (Until the new reg emerges, 915 has been approved by Rotax to work with fixed pitch props.)

Good or Bad Timing?

What about the coming LSA regulation and the likelihood of LSA being allowed more weight (see this article)? This question is answered because Wave, like Icon, won a weight increase. While other manufacturers wait to find out exactly what the design parameters will be, Vickers is ahead of the game, having already been granted extra weight. Afterward, Paul observed, “Some of our safety features [allowed by the weight bump] include water-maneuvering thrusters, CrossOver™ landing gear, increased horsepower, and the required fuel capacity to ensure the Wave is operated safely and can perform its mission.”

With FAA’s weight blessing, Vickers need not wait on the new FAA regulation as they prepare to launch their LSA seaplane.

First flight is ahead — though this is one of those nailing-jello-to-a-wall stories. First flight is something a designer never wishes to rush. Yet after all the time spent working on this design, the desire to see Wave go aloft must be tremendous — not even considering what pressure those waiting for the design may be exerting.

Paul and his Vickers team have worked hard, not only to make a dashing design but creating one that is easier to build. Vickers reports their total part count is a fraction of Icon’s for the A5, which should translate into quicker, easier, surer building and that in turn may help the New Zealand company keep their prices well below A5’s. Wave is composed of around 400 parts where Vickers said 1,800 or more parts is more common. Each part adds a material and labor cost.

In another photo, you can see a door leaning up against the hangar wall. Reportedly, Wave will use an aft-sliding door to enter a rather spacious compartment.

Wave also planned to use a novel arrangement of main gear — called “CrossOver” gear — such that it could handle the expected duties without needing to be retracted. Until the company gets first flight in their logbook, they’re concentrating on the essentials so it’s too early for confirmation of specific features.

Despite the uncertainties, Paul Vickers planned the design so meticulously that the first flight aircraft looks highly finished and not the sort of roughed-out prototype that often flies as a “proof-of-concept.” If Paul achieves what I think he might with this impressive aircraft, the POC first-flight example might end up being very similar to the production aircraft that will follow.

Here’s a video I recorded with Paul Vickers as he visited my home airport in 2017 (although Paul has since changed from the Titan engine to the Rotax 915iS)…

Better News on Proposed LSA Regulation — Clearing the Air on FAA’s Latest Information

By Dan Johnson || 88 Comments

In about one year, FAA may announce their new regulation for Light-Sport Aircraft.

This rule, sometimes called MOSAIC, proposes wide changes for the light aircraft segment, including an entirely new term: Light Personal Aircraft (LPA).

Here in early summer 2021, new information was discovered that shines additional light on what is ahead.

I am privileged to have recent information in which I have very high confidence.

While we do not know everything yet — neither does FAA itself — we are getting a clearer picture. Nonetheless, you should remember this is a proposal still in deliberation. It is not a completed regulation. We will know definitely what FAA recommends only when the NPRM (Notice of Proposed Rule Making) is released. My best guess for that is EAA AirVenture Oshkosh 2022 …about one year in the future. The final rule, after assessing all comments, is not expected until the end of 2023.

LPA and Sport Pilot Certificate

The first time anyone outside FAA heard about Light Personal Aircraft was one year ago, in May 2020. In this time of great society-wide distraction many became aware of new term later in the year.

Icon secured a weight increase for their A5 seaplane using a petition process.

LPA represent the full range of aircraft the FAA will likely propose as suitable for issuance of a Special Airworthiness Certificate using a manufacturer’s statement of compliance to FAA-accepted, industry consensus standards.

LSA would be those LPA that meet an expanded definition of LSA as described in previous articles, that is, in the new reg, LSA would become a subset of LPA. LSA may continue to be operated by Sport Pilots and maintained by LSRM. LPA that exceed the LSA definition would require higher certificates for pilots and repairman.

Another way to say this is: all LSA will be LPA, but not all LPA will be eligible for LSA.

Rulemaking is a machine with a lot of moving parts. Many people are involved but close to the heart of this proposal are two divisions or departments in FAA. One is dedicated to aircraft certification. A different one is dedicated to pilot certification and flight operations. A Sport Pilot does not receive the same training as a Private or better and may not have the same experience as a higher rated pilot. Therefore, it is reasonable to give greater privilege to the higher certificate levels.

When I write “Sport Pilot,” I mean those who hold an actual Sport Pilot certificate and those who have a higher certificate but wish to exercise the privileges of Sport Pilot. For many of the latter, this relieves them of the need to obtain an aviation medical or use Basic Med in order to fly Light-Sport Aircraft.

This point needs to be stressed: Even as LPA arrives, LSA will see “expansions.”

Setting the Record Straighter

Agency personnel are still very actively discussing this internally and many points are still being deliberated and refined. However, one person said, “The original ideas we shared with you [in previous discussions] remain as we informed you then. The plan is to expand LSA significantly.”

With the following, I will seek to address reader comments I received. These issues appeared to be of greatest importance.

I start with one that garnered the most response and I’m pleased to restate this.

Weight ••• Light-Sport Aircraft will be allowed more weight although this evolved somewhat differently than once expected. LPA entered the picture and will be the larger aircraft …but LSA will also benefit.

How much weight an LSA can increase will be determined with Power Index — essentially wing loading and horsepower considerations. Few readers might fully understand Power Index (details here) yet use of this formula allows weight flexibility well beyond currently-prescribed values.

Those of you who lamented the likelihood of no weight increase for LSA can breathe a sigh of relief.

Sport Pilot Privileges ••• Sport Pilots will be allowed to use their certificate to fly LPA that meet the parameters of the new definition of LSA, which will include (somewhat) heavier airplanes and all LSA meeting the present day definition of LSA. When a Light Personal Aircraft exceeds the final definition of LSA, you will need a Private Pilot certificate or higher.

How heavy an airplane can a Sport Pilot fly? That is still in discussion. Sport Pilots will not be able to fly an LPA that exceeds LSA parameters as described in the new regulation, but Sport Pilots will be able to fly a heavier airplane than a present-day 1,320-pound LSA landplane. Where precisely is the separating line? We’ll learn more about that later.

Maintenance ••• Since heavier airplanes than today’s LSA could be flown by a Sport Pilot, it seems reasonable that a Light Sport Repairman-Maintenance (LSRM) could work on an airplane that a Sport Pilot is permitted to fly. For those already using or contemplating earning that credential, an LSRM will be able to maintain LSA as described later. LSRMs will not be able to work on LPA that are beyond the eventual LSA description.

Legacy GA Airplanes ••• A good number of you yearn to operate a Cessna 150 or 172, a Cherokee, or some similar aircraft using a Sport Pilot certificate. If such airplane meets the description of a LSA under the new regulation, yes, it may be possible to fly one as a Sport Pilot. A Cessna 150 or a Cherokee 140 may qualify but a Cessna 210 or a Bonanza will not. The boundary line relates to Power Index, but some of you who wish to fly a legacy GA aircraft may be satisfied.

Single Lever Control ••• While this automated prop control is something that can be installed on LSA in 2024, it will not be limited to LSA. LPA may also use SLC and could have additional prop control options.

Fully-Built Gyroplanes ••• This request remains on track. After more than 15 years, Special LSA gyroplanes should become a reality.

Electric Propulsion ••• This remains in the proposal for LSA (as well as LPA). Hybrid systems will also be permitted.

Aerial Work ••• Not the same as “commercial operations,” aerial work remains under consideration although what pilot certificate may be needed is to be decided by the flight standards people. LSA (the aircraft) will be able to do such work, as eventually described, but a higher pilot certificate may be needed for certain activities or certain airplanes. This statement in the May 16th article still stands: “Aerial Work is actually defined as a pilot privilege and not an aircraft limitation.”

Light Personal Aircraft ••• These will take the lead position in the new regulation and LSA will become a part of LPA. Both will be allowed to get heavier than today’s LSA. However, I add that not all LSA need to get heavier. Weight shift and powered parachutes are two obvious examples that are well optimized under today’s weight limits.

ASTM Standards Work ••• LPA will be built to FAA-accepted, industry consensus standards like present-day LSA, but updated standards are needed to address all the changes that will be part of the final MOSAIC rule. Revision of all LSA standards is taking place now based on information the FAA has shared, but newly-approved aircraft like gyroplanes or technologies like electric propulsion may not have completed standards when the rule becomes final. So, these newly-approved aircraft are coming, but there will probably be some time lapse from when the rule becomes final and when compliant designs are available for purchase.

Working Together

LAMA, represented by myself and Roy Beisswenger, had numerous fruitful discussions with FAA. We went to many meetings and made several trips to FAA headquarters in Washington, DC. In most of these meetings we found FAA people interested to advance LSA in the aviation world and interested to hear what changes we wanted. LAMA was satisfied with those discussions and, indeed, FAA incorporated into the proposal every LAMA request. All LAMA’s “asks” are captioned in this article. In the end, we got more than we asked for.

I am pleased discussions continue so we can all learn more about what lies ahead.

Youth In Aviation — Is Aviation in Trouble? Or, Are Kids Finding their Way into the Sky?

By Dan Johnson || 3 Comments

I don’t believe the line about young people ignoring aviation. Maybe we older pilots don’t see enough action at flight schools, but not all flying happens at major flight centers.

Lots of other avenues are available. For example, EAA has an endowment from the late-aviation philanthropist James Ray that allows the Oshkosh organization to give scholarships for around 100 pilots per year. LAMA is working with EAA right now to add more scholarships; these will be specific to Sport Pilot and must occur in Light-Sport Aircraft. EAA chapters around the country can participate.

Regarding youth coming into aviation, my earlier work shows key numbers. Here’s part of what I wrote…

Most pilots I know think the pilot population is graying quickly and that we may be in danger of running out of pilots. GAMA’s stats say otherwise. The biggest single category may be what you expect with those aged 50-64 counting 179,277 pilots but the surprising second largest segment is close behind. Those aged a young 20-35 years old number 173,396 pilots. The 35-50 cohort is much smaller, perhaps as they are busy raising families and paying for mortgages and college eductions for their kids.

Welcome New Sport Pilot,
Jatniel Acevedo

For 15 years at Sun ‘n Fun, LAMA has hosted the LSA Mall in Paradise City. Over that decade and a half, it has become a fixture of the Lakeland, Florida airshow — officially on the map visitors receive as a place of interest. LAMA is grateful to Sun ‘n Fun for helping to make this feature possible.

Setting up the LSA Mall takes some extra hands, so LAMA has used various great volunteers over the years. One young fellow joined us a few years back. His name is Jatniel Acevedo and he is the subject of this article, but not because he’s a volunteer, helpful as that has been.

I was introduced to Jat by my wife, Randee Laskewitz, who is essential in the operation of the LSA Mall. We’ve worked together on the Mall for a decade and a half but I have to give credit where it belongs. As I zoom around the grounds collecting great airplane content for you readers, Randee and the volunteers hold down the fort. Jat is a valuable member of the team.

Randee and I have observed him for several years and have come to be very impressed with him and his aviation-oriented family. The video will provide more detail about this lifelong experience in aviation.

Jatniel attends the Central Florida Aerospace Academy across the street from the Florida Air Museum. It has been a key part of the ever-expanding Sun ‘n Fun campus. At this year’s event, Jat had two big announcements.

Jatniel’s first passenger after winning his Sport Pilot certificate was a very important person: MOM! Wanda Acevedo and her pilot husband, Ariel, are the kind of family support vital to Jat’s success in aviation.

He had passed his flight check to become a Sport Pilot. That’s noteworthy by itself. Determination and hard work on his part led to this success but his very supportive family was essential.

In mere weeks, Jat will graduate from CFAA and continue on into college with aviation as his goal.

I’m telling you, folks — if this young man is any example of what’s ahead for aviation in America, all is well. The stories of gloom and doom for aviation are either overblown or just plain wrong.

Jat’s not alone, of course. Many young people around the country — EAA’s flight instruction scholarship winners among them — are pursing aviation. This is only one story but it’s a good one and I am honored to know this young man and wish him all the best as he moves on in his education and then his flying career.

I hope you’ll join me in applauding Jat, other young pilots, plus the mentors, professors, and instructors who have helped these aspiring aviators.

These people are the future of aviation. Dad Ariel and Mom Wanda have good reason to be proud of their son!

Special Thanks!

Troy Townsend — of ITEC Maverick (video) development fame — is a FAA-designated DPE who can help give a check ride to a pilot of a sub-87 knot aircraft.

Ariel Acevedo, Jatniel’s Dad, wanted to express his deep appreciation for CFI Bo Feldman and Designated Pilot Examiner, Troy Townsend of FliteChek.com for their efforts to help Jat earn his Sport Pilot certificate.

“These days, it is kind of hard to find a DPE that is willing to do the check ride in a Light-Sport Aircraft,” Ariel said, “particularly for aircraft that fly under 87 knots. Bo and Troy were a great resource to keep alive Light-Sport Aircraft [that fly] under 87 knots.”

Lots of LSA enthusiasts are not truly aware that FAA makes a distinction between sub-87 knot aircraft and faster ones. Most fixed wing LSA cruise faster.

Yet Quicksilver, Hawk, Kolb, Smithsilver, Challenger, most trikes, all powered parachutes, and many more flying machines operate at speeds below 87 knots or 100 miles an hour.

Jatniel’s Dad, Ariel, got his son started at a tender young age and clearly gave him good guidance and counsel on top of providing a thrill for a young man.

When cross-country speed is not the goal, these sub-87s offer a special joy of flight that is not available to most faster aircraft. You can see the countryside at what I call “human speed.” The terrain slips by slowly enough for you to take in the nature, wildlife, and overall beauty of this world. You can’t do that in a biz jet at 500 miles an hour at 25,000 feet.

However, most CFI or Sport Pilot Instructors are focused on the faster aircraft and lack experience themselves in slower flying aircraft.

That’s why Ariel wanted to thank Bo and Troy and FliteChek.com for their willingness and experience with these slower flying machines. Low and slow has a beauty missed by some but these fellows are a great help. I add my thanks to that of Ariel.

Here’s my interview with Jatniel Acevedo. I hope you will watch it and share it. More young people need to learn this story.

For more information about young people headed toward careers in aviation, I recommend you look into AviNation, a publication focused on this subject by a good friend, Jacob Peed.

Sun ‘n Fun 2021 / Reflections 2.0… Powrachute, Gyro Technic, Stick-On Autopilot, Duc Props

By Dan Johnson || 4 Comments

We continue with further coverage from the first major airshow in almost two years… THANKS to Sun ‘n Fun 2021 for helping present these interesting aircraft and more.

This article has news …about two aircraft in a category I refer to as “alternative aircraft” …about an easily-mounted autopilot you can actually afford …and the success story of a French prop maker now well established in the USA.

Alternative aircraft is my umbrella term for weight shift aircraft (trikes), powered parachutes, gyroplanes, carriage-equipped powered paragliders (not the same as powered parachutes), Light-Sport motorgliders, and Light-Sport Lighter-than-Air flying machines. These unorthodox, not-mainstream aircraft have maintained a steady share of sales; around 100 new such aircraft enter the U.S. market every year.

Counting all types, the “alternative aircraft” sector may account for a quarter or more of all LSA sales. Alternative aircraft have attributes that drive customer inquiries: better affordability and unique flying qualities.

Not interested in alternative aircraft? That’s hardly surprising as most American pilots were trained in conventional, three-axis, tractor-engined aircraft, usually with a control wheel and rudder pedals. Most of those pilots will stick with a familiar configuration and therefore the LSA market caters to that large pilot community. Others yearn for something different or something more affordable.

Looking Further
Sun ‘n Fun 2021

Powrachute Powerhouse — Powered parachutes (PPCs) grew nicely last yet after a dip in 2019 registrations, but nearly all of that came from the Powrachute brand. This Michigan producer — which does significant work for Evolution Trikes and manufactures parts for other producers — nearly doubled its registrations from 2019 to 2020.

From its heyday back in the ’90s, powered parachutes have become a “mature” segment within recreational aviation. You can get a Sport Pilot certificate in a PPC in just 12 hours (assuming an apt student). Cost of a 912-powered rig is less than $40,000 for a well-equipped 100-horsepower Rotax 912-powered Airwolf; the engine alone is nearly half the total, making this machine “affordable.” Even if you are most tuned into fixed-wing flying, those facts may get your attention.

Here’s your cockpit …with a great big view. Pretty simple, huh? Even the joystick is only for taxiing; otherwise you fly with your feet.

Other active PPC developers and producers include SkyRunner and it’s gnarly, large, and “twin-engined” combo powered parachute and ground vehicle; several sales are underway to the U.S. government and military. Infinity Powered Parachutes has also been active at airshows, including last year’s Midwest LSA Expo.

If a $38,000 aircraft with perhaps the broadest viewing platform in aviation catches your interest, how are you going to learn to fly one? As powered parachute manufacturing has matured the training market has tightened …yet gotten better. Roy Beisswenger‘s Easy Flight — which sells the Powrachute line including Airwolf (pictured nearby) — offers a premium course in two locations: Illinois in the summer, or Florida the rest of the year. Roy knows what he’s teaching …heck, he wrote the book on it, a veritable PPC Bible.

Gyro Technic’s VX1 Gyroplane — In the rush to build ever-slicker models, the gyroplane industry has dedicated itself almost exclusively to two-seat aircraft. Some are now side-by-side though much more common is tandem, fore-and-aft seating. Enclosures have become common.

Those older American gyroplanes — think: Bensen Gyrocopter — were nearly all single seaters. Maybe that was best then, when stability was different than today. Then I discovered the VX1 at the Midwest LSA Expo. Hmmm, a modern gyroplane with all the present-day knowledge but in single seat form. Intriguing. It doesn’t look like other modern gyros and the video below will explain.

Lots of buyers want a second seat for a friend or their spouse yet more often than not aircraft are flown solo. A single seat aircraft has some advantages and the pilot can merely enjoy him or herself without have to assure their passenger is comfortable. Single seaters can also cost less partly because they don’t need as much engine.

Combine these attributes with some of the finest, beautifully-accented machine work you’ll ever see and Gyro Technic truly has something in their VX1. Finally, the Minnesota company is rare in that it also makes its own rotor blades and can supply other producers.

Levil’s Sticky-Backed Autopilot —Ruben Leon, the leader of Levil Aviation, nearly always wears a friendly, excited smile on his face. He also seems to always have some new development of interest and Sun ‘n Fun 2021 proved this theory once again.

Levil Aviation greatly empowered the role of tablets in the cockpit today by pioneering the first iPad-compatible wireless avionics suite in 2009. Today’s iLevil Sport ($795) is a portable unit bringing AHRS, GPS technology, and data recording. Compatible with both iOS and Android, this friendly user device can connect with a wide variety of apps in the market.

You might pair iLevil Sport with ADS-B receiver Astro Link ($599) to have real-time weather and traffic. Link both to your iPad and have a full-fledged panel for less than $2,500 that can compare to panel-mounted digital instruments costing two to ten times more in LSA. Astro Link boasts a low power consumption, has no need for remote antennas, and Levil said, “It captures the weather and traffic information even where other devices won’t reach.”

Carlos of Aircraft Automation (center) shows the Super Eco stick-on autopilot to a prospect.

A few years ago, by collaborating with TruTrak, Levil was a partner in developing the Eco, a simple autopilot that some have called an “anti-servo tab.” This is a simple, carbon fiber, electric tab that can literally (and advisably, to avoid drilling holes) be stuck to your aileron and elevator to produce a low-cost ($2,700) autopilot. The cockpit control for the unit is itself a fairly capable instrument.

“Autopilot HSI AP2000 controls the airplane by the sole use of trimtabs,” said partner Aircraft Automation. “[This] makes it extremely reliable, light, safe and easy to install. It also serves as a nice backup instrument for your EFIS [or iPad].”

“Super Eco is supplied with two model airplane servos, wiring harness, pushrods, and respective trim tabs for the roll and the pitch axis,” said Carlos of Aircraft Automation. “Since Trim Tabs are used for primary control there are no mechanical links with flight controls, pilots can override the trim tabs easily. Control links and cables are free to move with no additional friction since there are no conventional servos installed. The aircraft will be automatically return to trim should the autopilot disconnect.”

Duc Prop Success Story — Industry observers have seen this unfold before. An international company enters the U.S. market but comes to recognize the complexities of a large, mature aviation culture as exists in America. To do it right, you really need true U.S. presence. A few years ago, Duc Hélices set up shop in Sebring, Florida as Duc Propellers USA. Up against many solid players lead by Sensenich providing vigorous competition, Duc has worked hard and it’s working.

Duc took the challenge in hand and found in Gaetan Fouozing (photos) the right manager for the job. The company has gone from sales in the low hundreds of thousands into a low multimillion dollar enterprise. Plus, these days, Gaetan is the man. He does it all.

Of course, he is a sales and service outlet for Duc Hélices. Manufacturing occurs in Frontenas, France. According to Gaetan, the French enterprise is humming at its still-new headquarters with new space and new personnel. Good for Duc!

Of course, think about it. Whatever the powerplant, a prop is needed. Rotax power. Continental power. Viking or Aeromentum power. Electric motor power, single engine, twin engine, multicopter …they all need props (or rotor blades) — and in the case of the multicopters, they’ll need six, eight, 10, or more, a gold mine for a prop maker. Duc also makes rotor blades for gyroplanes and specialized blades for eVTOLs.

To reach all this action in the USA, you gotta be here. Duc is home in America.

We continue with further coverage from the first major airshow in almost two years… THANKS to Sun ‘n Fun 2021 for helping present these interesting aircraft and more. This article has news …about two aircraft in a category I refer to as “alternative aircraft” …about an easily-mounted autopilot you can actually afford …and the success story of a French prop maker now well established in the USA. Alternative aircraft is my umbrella term for weight shift aircraft (trikes), powered parachutes, gyroplanes, carriage-equipped powered paragliders (not the same as powered parachutes), Light-Sport motorgliders, and Light-Sport Lighter-than-Air flying machines. These unorthodox, not-mainstream aircraft have maintained a steady share of sales; around 100 new such aircraft enter the U.S. market every year. Counting all types, the “alternative aircraft” sector may account for a quarter or more of all LSA sales. Alternative aircraft have attributes that drive customer inquiries: better affordability and unique flying qualities.

Sun ‘n Fun 2021 / Reflections… Skyleader, Luscombe, Rev XS Winner

By Dan Johnson || 4 Comments

Continuing news from Sun ‘n Fun 2021 is rolling in from across the country. Even while most international enthusiasts were unable to attend because of covid-induced travel restrictions, Americans turned out in strong numbers — and had a great time.

FAA personnel casually (not officially) reported some 70,000 tickets bought on Saturday alone. I have no idea about such numbers historically, but by any measure, that’s a darn fine performance, the equivalent of a major football stadium stuffed full of fans. I am so relieved for Sun ‘n Fun. Inc., and I’m sure my relief is but a drop in the bucket compared to that felt by Team Sun ‘n Fun.

If Oshkosh goes similarly, then I think it will be fair to say recreational aviation is nearly back to normal. Fortunately, in the Year of Fear that may be ending, tons of builders worked on kit airplanes, loads of LSA owners got out and flew their birds, and Part 103 ultralights probably set a record for shipments and kept sport pilots up in the air.

Update on the Part 103 List — The survey of Part 103 producers slowed while I attended and worked Sun ‘n Fun but I’m back on the project. I still need to hear from many manufacturers. If you own a Part 103 aircraft of any kind from any supplier, you can help by asking your producer to respond to my inquiries.

3 Distinctive Aircraft
from Sun ‘n Fun 2021

Now let’s continue our look at airplanes of interest to those seeking light recreational, affordable aircraft. I highlight three aircraft, each quite different in its own way.

—Luscombe is an all-American original. The company now based in Jamestown, New York made an appearance at Sun ‘n Fun 2021. I finally found it in vintage parking. It was well located; this was a genuine vintage example, nicely polished and prepared for the faithful to admire. Meanwhile, the company is taking a measured approach to re-entering the Light-Sport Aircraft market.

Steve Testrake, whom I met in Lakeland, has explained that the newly-reorganized company (see link above) will begin by supplying much-needed replacement parts to the existing Luscombe fleet. As the renewed factory sets up, they will add to the list of components. This effort will be treasured by many Luscombe owners. They love their aircraft like few other models I have ever investigated, making a maintenance-grounded Luscombe agonizing for those enthusiasts. Steve and his team aim to resolve that. Bravo!

Then, he described a plan to go slowly at a return to manufacturing the vintage aircraft as a Special, fully-built LSA. Another bravo, including for taking the time to get it right. Readers should understand getting semi-tractor trailer loads of inventory, tooling, jigs and more will take some time to get set up properly.

It was 14 years ago on the EAA Sport Pilot Tour, not long after the first emergence of Light-Sport Aircraft, when Luscombe won acceptance as a SLSA. That’s when I had my first crack at this much-beloved aircraft. Here’s what I had to say about this storied model from America’s past. This one stands the test of time well flying as wonderfully as I’d always heard. That’s worth another Bravo!

—Skyleader 600 looks familiar to some viewers. It should, though a lack of immediate recognition is understandable.

Early LSA enthusiasts knew this aircraft as the Jhilivan (or Kappa) KP-5. It was one of the first Special LSA to win FAA acceptance; here’s my review of it back in 2006. Then the design went away… for years. It came back once as the refashioned Skyleader, faltered again in America, and is now back with stronger representation.

I recorded a new interview with importer Michael Tomazin and that will follow after editing. Meanwhile, here’s a video review of Skyleader 600 with the former importer.

Michael’s enthusiasm for the aircraft is evident as he talks about the model. Several features are worth observing.

First, entry is over the wing as with all low-wing models but the canopy arrangements is great at least two ways: it slides aft on a carbon fiber-reinforced rail that makes moving the large covering easy. While not intended as a roll bar, the carbon bar does aid entry. A canopy articulated in this fashion is also likely to be more secure in gusty winds.

Once up on the wing, you can simply stand on the floor in front of the seat and sit down. Unlike its predecessor from Kappa, Skyleader 600 has both seats side-by-side; KP-5 had a slimmer cockpit width and staggered the right seat aft a few inches to give more room and a wider view. While the current configuration is more commonplace and will probably please more buyers, I rather liked the staggered seating; it gave the pilot in command great visibility out both sides.

Another nice bit of engineering is the far-extending Fowler-style flaps (nearby photo). This flap construction is more complicated than simple hinged flaps but the Fowler design allows lots more airflow making the surface much more effective. When the flaps extend, the elevator trim automatically adjusts to reduce pitch changes when deploying the large flaps. Of course, this level of sophistication is more costly than simpler constructions.

—Rev XS from Evolution Aircraft, America’s premium trike developer, extends an amazing run starting with the letters “R-E-V.” First, Revo. Then, Rev. Then, Rev X. Then, RevoLT. And now, Rev XS. I don’t recall for sure, but it may be that each of these won an award; they’re that well done.

So, no surprise that Rev XS won an award at Sun ‘n Fun 2021, except this time with an attractive difference. This winner was built by Amy Mednick. Until a few years ago when Larry and Amy Mednick got married — at Sun ‘n Fun, of course 😎 — you knew her as Amy Saunders. She’s been in this game a while.

Only a couple weeks before Sun ‘n Fun, I heard from her. “I thought you would to know, since I have talked about it for years,” she texted. “I am officially a Weight Shift Control (WSC) Certified Flight Instructor with Private privileges!! …as of this morning,” she added enthusiastically!

Then at the airshow she won the “Outstanding LSA — Trike” award. Indeed, it’s been quite a year for Amy.

I’m not sure I recall ever seeing Amy when she wasn’t smiling but this one-two set of accomplishments really had her beaming. Right behind her was very capable designer and husband, Larry Mednick. His smile was nearly as broad, understandably.

Evolution Aircraft enjoyed a banner year in 2020, despite all the covid anxiety.

It turns out that open-cockpit trike flying was embraced by many last year and Larry noted that the enthusiasm is continuing into 2021. This husband-and-wife team appears set to have another good year in 2021. Contratulations to Amy in particular and Evolution more broadly.

A Tribute to Mike Collins — One of the most famous photos taken during the 1960s moonshot was this one by Mike Collins, who just died at age 90. His photograph reveals Neil Armstrong and Buzz Aldrin returning from the first steps on the moon, plus the entire planet… meaning everyone alive at the time — except himself. I was a young flight instructor when this monumental event in human history occurred. Like most people, it left a lasting memory on me. Rest in peace, Michael Collins.
