The KRT2 VHF transceiver has already been installed in over 10,000 aircraft across Europe. It features an integrated intercom, a dual watch mode (the pilot can monitor two frequencies at the same time) and it has 100 memory slots for preferred frequencies that tie in with airport identifiers. The radio can be updated with new software at any time. Like the transponder, the KRT2 features digital electronics which make it light, compact and reliable.

This article has been updated… Technology company TQ Group established a reputation for high quality engineering and precision products. The German enterprise will debut two of their general aviation products for the AirVenture attendees at the end of July 2018. One is an ADS-B transponder in the final stages of certification and the other is a VHF Transceiver that boasts a strong following in Europe. You may already know the name Dittel. Walter Dittel has been a respected manufacturer of small, high quality, low current drain aviation radios and accessories. With the acquisition of leading European avionics manufacturer Dittel in 2016 TQ was able to expand its core capabilities and expertise, while substantially enhancing its R&D resources. Through its business unit TQ-Aviation, the company has been serving the aviation sector for more than 15 years, delivering advanced electronic products to well-known aircraft manufacturers and airlines. TQ-Group now employs nearly 1,600 employees at 14 locations throughout Germany, Switzerland, China and the United States.
Infotech in Part 103 ultralight vehicles means far more than GPS or even synthetic vision digital screens (imagine an iPad mated to a 
Developers probably use Part 103 because they can do what they want sooner, easier, and not require a pilot's license — or much FAA oversight. Conversely, any aircraft with two or more seats must use another FAR section inviting much more regulation.
"Infotech" is a catchall word suggesting computer technology or software or algorithms. It may be hard to explain precisely but it conveys an image of modern, fast, and cheap. Many fields are being altered by infotech. Why should aviation be any different?
In a CBS News article, Leng was reported saying, “When you press the thumb-stick to climb, you have absolute full control. When you stop in the middle of the air and go off the joystick, the aircraft freezes." These phrases are hardly the way a pilot would say it; perhaps he stated it this way because he was speaking to a non-pilot reporter.
Although BlackFly claims full amphibious capabilities, "It is primarily designed to easily operate from small grassy areas and travel distances of up to 25 miles at a speed of 62 mph." said Opener. It presently has a 25-minute flight endurance. See 
Tested by Eskil Amdal, Equator reportedly accelerated to 70 knots before leaving the ground and flying down the runway at 100 knots at nine meters (about 30 feet, at the edge of ground effect), before landing smoothly. Amdal reported stable flight with good controllability in all axes. Two more flights were performed the following day, further establishing confidence in the flying characteristics.
"The aircraft is a prototype developed by Equator with very limited means since 2010," explained the company. "It can operate from land or water, and with its small electric motor, low float wings and good aerodynamics, promises to rival land planes on performance."
"Equator's core goal to make flying more available to more people, by supplying, green, silent and practical aircraft to the market," added the company. Equator benefits from a very large space inside (nearby photo), and "a simple intuitive cockpit that makes it easy to learn to fly."

The report continued, "Koivurova said that the accident would not pose a major setback for the small plane manufacturing firm,” while adding that the company will suffer additional loss by taking one customer plane out of the production queue for further testing.
The aircraft retails for 169,000 euros ($199,000 at today's exchange rate). Atol Avian currently has six planes in production. The amphibious side-by-side seating Atol 650 LSA is made out of wood composite with foldable wings. See

In Virus (yes, I've heard most the jokes about the name) Michael refers to the best seller of the comprehensive Pipistrel line. The reference here is to Virus SW. While the company has succeeded with a number of their other models, Virus SW — the shorter wing span and higher cruise speed variation — is the clear front runner among their production.
This particular airplane — nicknamed "Mahi" by its owners — is part of the WE! Expedition project, in which two female pilots, a mother and daughter, intend to fly around the world. Pipistrel will no doubt promote that voyage as they've done other global circumnavigation flights.
If you want to check out the Pipistrel line, you have a great chance coming soon.

"We will also have 10,000 copies of the new Pipistrel Magazine available for giveaway," said Coates. "This magazine features the full history of Pipistrel along with the different projects we have been involved with in the past 30 years." Such company magazines used to be called "house organs" and Pipistrel's features information about the whole aircraft line.
Pipistrel was established in 1987 as a small backyard workshop and registered as a company in 1989. It started as a producer of powered hang-gliders, but in the 30 years of operation it has grown into an influential, internationally renown company
* A very common mistake is to refer to FAA accepted SLSA as "certified." This is incorrect. SLSA that FAA has approved have demonstrated compliance to ASTM standards and have verified their quality processes and best practices to FAA examiner's satisfaction. They may have proven this via an official FAA audit but they are not "type certified." TC aircraft get "Standard" Airworthiness Certificates. SLSA get "Special" AW Certs. Other countries that use ASTM standards as a basis for approval sometimes add their own "certifications."

Ultra Shock also retain its strength. "We loaded and drop tested [Ultra Shock] up to 1,000 kilograms (2,200 pounds) from 120 centimeters (about 4 feet) above the ground without any damage." That may not sound like such a high drop height but I've seen test reports and can attest that is a very demanding test, especially at such weight. The design "virtually eliminates the touchdown rebound," Pascale said. "We proceeded from the original Savage Cub-S," Pascale continued, "reinforcing and refining the fuselage framework, increasing … the cockpit height, improving the accessibility, and generally improving ergonomics on board." In other words, he made sure larger pilots will fit well.
Despite Ultra Shock's lighter weight design, Zlin said the “engine bay can accommodate different engines from the standard 
He managed to reach a targeted and demonstrated minimum empty weight — an impressively slim 649 pounds — with a 100 horsepower Rotax 912 with radio and basic instrumentation and a weight savings program which introduced carbon fiber elements, light weight battery, and Oratex fabric covering (a weight-saving material with already colored cloth) in place of classic heat-shrink Dacron, among other choices.It appears he succeeded well. Ultra Shock is significantly lighter than most of the other Cub-clones, which should translate to great performance with the Rotax 912 and reduced overall expense. Zlin is targeting €95,000 (about $115,000) for a well-equipped Ultra Shock but for U.S. pricing and availability, please 
Many pilots who first set eyes on the SW51, a precisely faithful 70%-scale imitation of the famous North American Aviation P-51 Mustang managed to utter a single word: "WOW!"
Can you blame them? Look at this bird. The shape is classic and the detail is exquisite, finished down to the last rivet to mimic the famous World War II American fighter. Except, it's a kind of fake. I better explain.
We've seen this spectacular execution of Hans Schwöller before. It was then called FK51 and we reported it earlier in 
Thanks to his youthful associate, Christian von Kessel, SW51 has been refunded and reenfranchised, bringing it to reality. The earlier producer group stumbled and this amazing construction never reached market.
Can you handle a machine that looks this awesome? As you hear Hans and Christian state in the video, SW51 is easy to take off and land and docile in flight. Early test flight were done by a Lufthansa airline captain (image). In fact, other P-51 clones also boast relatively manageable flight qualities, unlike the North American original that demanded considerable training and good skills, according to those with experience in the powerful machine. (If you have extra time on your hands, you can 
For those ready for the hottest action, you can build the Experimental version and install a Chevy V-8 engine, but that's well beyond the scope of this website. If you're curious, though, ScaleWings says the airframe can take up to 600 horsepower.
The most distinctive quality of SW51 is its tight adherence to the original look, albeit it as a 70%-scale replica of the historic P-51 Mustang. The earlier report referenced above goes into more detail but I must repeat that although this looks remarkably like a riveted structure, it is not. SW51 is a carbon fiber execution of the original so true that a reported 100,000 rivets are molded into the finish. I saw people examining the example at Aero Friedrichshafen run their hand over the skin and they may still not have realized it was something of an illusion. Yes, it's that good!
SW 51 also bests the original with detachable outer wing sections that feature an autoconnect design; wing locking connects flaps, ailerons, pitot tube, electric and fuel lines. The developer reports the process takes one person a mere five minutes to complete.
If you want the LSA version, it will be supplied with a fixed gear configuration; the manufacturer understands what is needed for the U.S. market. For those that want the whole Walter Mitty effect with big engine and high speeds, 
Gulp! Can you afford this beauty? Budgets vary by person, but SW51 is roughly comparable to other higher-end Special LSA. In Europe, the assembled base price is about $182,900, though shipping to the U.S. and other countries will add expense. Yankees wanting the retractable version will indeed have to choose a kit, with the cost starting at around $140,000 for a quick-build version, however, this does not include the engine. A wide range is available if you kit build, up to a very powerful V8 engine. Given what you may be acquiring, those prices are reasonably affordable if you yearn for the full fighter jock sensation of flying your own 70%-scale P-51 Mustang lookalike.

Years ago, back in the late 1990s, I flew an aircraft called JetFox 97. It resembled the Flightstar of the day and both were modeled on talented European designer Hans Gygax's designs. Along came Light-Sport Aircraft in 2004; years passed with not much word about the increasingly aged JetFox 97.
It's back and looking handsome, cloaked in a carbon fiber fuselage. Since this is an Italian design, it has the beauty we often associate with products from that country. I am describing Alfredo Di Cesare's FX1.
You can 
While FX1 clearly follows the Jetfox 97 — its overall shape, planform, and layout are very similar — the new model is very different in some ways not obvious in the nearby photos.
To start, FX1 uses a chrome moly steel internal structure, with a beautifully-shaped carbon fiber exterior, and riveted aluminum wings and tail.
No doubt, Alfredo's latest is a dramatic update from the one of two decades back.
Today, as then, the main engine choice is the Rotax 912 ULS carbureted engine but InnovAviation will soon begin offering the Rotax 912iS Sport fuel injected version.
We've got the answers and more.
FX1 will make its first showing at

The big Italian company that LSA enthusiasts know very well through models such as P92, Sierra, and P2008 has a large and growing presence in global aviation. Their developments are broad and delve into aviation segments large and small. They are also getting ready to celebrate a benchmark birthday.
This year Tecnam Costruzioni Aeronautiche — most pilots simply say “
The Leica CityMapper is specifically designed for 3D city modelling and urban mapping. It is the world’s first hybrid airborne sensor combining both oblique and nadir imaging as well as a LiDAR system.
Tecnam has a large staff to accomplish these diverse projects while building as many as four aircraft a week. Even with many employees, however, this is a impressive penetration of all aviation's nooks and crannies.
BRM Aero boss and chief design, Milan Bristela, has convincingly proven his visionary credentials. Here's 
All that space might be useful for another kind of enjoyment: bush flying, landing on river beds, camping …that sort of adventure.
For the new "bush" version of TDO, BRM again did a great job of finishing the interior, both in creature comforts (as seen in the nearby photo) or equipment.
To mount big Alaska tundra tires on their TDO, BRM teamed up with 
What's great about the Beringer/Alaska adaptation is that it follows Milan's mantra to keep as many new innovations as possible retrofittable to older models. That works here, too, but owners get a bonus.
Through the design of this Bush TDO model, Milan made sure a mechanically-savvy owner can switch back and forth. Use your fiberglass gear and wheel pants to go fast for travel but swap to bush mode when you want to fly for fun on the weekend, maybe at your cottage. Cool, huh? What wonderful versatility.

"Oh, don't worry," your friend replies. "Just move the joystick as you'd expect. If anything goes wrong, just hit the big red button and it will safely return you to precisely where you took off."
"But what about the batteries …what I run low on juice?"
"Ah, don't sweat that either. The machine knows and it will land you safely before you run out of power."
Would you, the expert fixed wing pilot, take the offer? Would someone else who always wanted to fly, but who was put off by the challenges of learning to fly conventional aircraft, want to take the offer?
Safety, low noise, performance, ease of control, and maintenance cost reduction are the selling points of Whisper, company officials said. They plan to move towards manufacture and marketing by 2020, hoping to sell ten machines in 2020, twenty in 2021, and forty in 2022. Those targets sound refreshingly sane to me, as opposed to other builders boasting huge volumes just over the horizon.
Current flight time is up to thirty minutes, they said, but representatives — like pretty much everybody else in the electric airplane development game — expect battery life to be increased with future technology.
An emergency parachute is part of the concept, however, it will also be possible to land in the case of a single rotor failure. It's actually quite believable that with eight motors/rotors, the loss of one could be fairly easily remedied with the others. It's just software …although that unveils the vulnerability in the near-future forecasts by some media.
Yes, of course. I 
Whatever the eventual solution, it has become more and more clear to me that multiple-rotor aircraft — some with wings that pivot to transition from vertical liftoff to speedier in-flight cruising — remain clearly in the future of flight.
I admit I am slowly being swayed from my love of conventional winged aircraft that I know so well to something with spinney or flippy propulsion. Oh, I don't see anything to replace the efficiency of fixed wings, for example, in the case of a gliding/soaring aircraft (think: sailplane or hang glider) but for many kinds of powered aircraft …well, the times, they may be a-changing.
I'll try not to overdo this reporting and for the next decade or so, developments will keep octocopters and such in the aerial lab, so to say. Meanwhile, the great news is that we have an embarrassment of riches with many choices of ultralights, light kit aircraft, and Light-Sport Aircraft. I hope you can enjoy one on this holiday!
And now… here is our video interview:
https://youtu.be/5kpsjjlR35k
For the moment, Brian is not designing. He's fighting for his very survival. …literally!
I am about to do something I never do on this website — for many reasons — but which I find worthy in this case. Let me have Brian's good buddy Jon Bailey tell you himself.
"I am a very close friend of Brian Austein. I am writing you to inform you that the day after Sun 'n Fun 2018 (on Monday April 16), Brian was diagnosed with Stage 4 lung cancer. It has moved into his brain. Brian is a fighter and he is fighting a tough battle right now. He is currently in Atlanta under evaluation for a second opinion. I will take him to another doctor on Tuesday (May 22nd) for his opinion.
"Please keep Brian and his family in your thoughts and prayers during this time.
"Dan, I know that you are well connected in the ultralight world and I know that a lot of ultralight people are amazed at what Brian has done. Can you share the attached Go Fund Me link? We set it up as a great way to give back and help out a man that has given so much to all of us."
Absolutely, Jon, I will put out the request and I have already contributed myself. Here's the 
From the beginning, Swan was planned with an enclosed cockpit so the pilot could be comfortable in low temperatures without needing a bulky flight suit. A cockpit heating system can be added as an option. Two ventilation systems are provided; one to prevent the windscreen fogging during taxi and another to supply fresh air. Alternatively, when the weather is hot, "the door can be simply removed," said Radu.
Dogs in the Cockpit? A few years ago, various stories began to pop in mainstream media discussing the car industry's newest focus …no, not only on how many cup holders they could install in your new ride — but instead on accommodations for pets, mainly dogs.
Why?
Easy. Some high percentage of all auto trips include bringing the family pet along for the ride. Design to that and you sell more cars.
Does this apply to airplanes?
Think what you will of this, it's a fact of modern life in America. Surveys reveal that 44% of American household have a dog, some 78 million critters. More than half of all dog-owning households take their pets when they travel by car. That's a big market. Cars that can readily allow the family pup to come along — preferably not riding in the driver's lap with its nose out the window — will find many interested buyers.
Should airplanes be different?
Dogs do love to go for a ride. Our last pooch dug it so much she wouldn't leave the car even after we got home. She'd stay inside until you took her out.
So when Scott Severen, now the man behind Jabiru aircraft sales, gave reporters at Sun 'n Fun 2018 a thumb drive with a bunch of photos of dogs inside, I sensed a fun story.
His J-230D LSA sport plane can easily handle the spouse and the family pooch.
No wonder really, as Jabiru sells this same airframe as a four seat kit in Australia, hence a cavernous aft cabin. Three doors is an added bonus.
Jabiru's big third door aft of the pilot's door makes an easy task to load your luggage unlike most low wing airplanes where it can often be challenging. Inside the J-230D you can put several bags of golf clubs or a large amount of luggage or a folding bicycle or two …or a few less bags and the family dog. Even larger dogs won't be cramped.
I used to try this in a Cessna 150/150 (it had a 150-horse Lycoming up front). Our dog at the time weighed more than 100 pounds. Flying with two people and the dog meant a reduced fuel load but for short trips it was fine. Once inside, Sunny had plenty of room in the 150's ample baggage area, but getting the big guy in that space was a challenge.
In flight I used the baggage tie downs and a special dog harness to be sure he didn't get tossed around should we encounter turbulence. The harness also prevented him from distracting or interfering with the pilot. He didn't seem to mind; a few minutes into the flight, he would lay down and sleep.
Jabiru J-230D is way better, easier on you, the dog, and the airplane than my venerable Cessna 150.
I can think of quite a few other reasons you might want to have a closer look at 
Joe knows his light seaplanes. He’s built at least one Searey and he used to fly it daily from Spruce Creek to a lake in Tavares, Florida where Progressive Aerodyne manufactures Searey. For a couple years, Joe was CEO of the operation making him highly aware of this niche of airplanes.
Searey — The most established of the collection is this veteran design from 
AirCam — The lone floatplane of the group is also the only twin engine of the group yet this larger-than-life airplane still qualifies as a light aircraft, easily so. Given its modest weight, the presence of two Rotax 9-series engines on this kit makes it a formidable performer but one that can use that capability at slow speeds, making the airplane an absolute delight for the kind of low-elevation flying that many others aircraft should not attempt. Around 200 are flying. Kit builder 
Aero Adventure — The Aventura model, seen here in its new S-17 configuration, dates back as far as the Searay but because of ownership changes the design also evolved uniquely. Originally known as the Buccaneer, it became of the Aventura when Carlos Pereyra added his exceptional fiberglass skills to the hull. Current owner, Alex Rolinski, has taken the design into the CAD age and beefed up its performance. The S-17 model boasts a 117-horsepower AeroMomentum Suzuki-based engine and attractive options; the package has been attracting strong interest for 
Super Petrel — One of the most unique entries is the bi-wing Super Petrel LS from 
Icon A5 — Thanks to sophisticated, California-style marketing, 
"Wave eVTOL is a four-seat, semi-autonomous hybrid and will harvest 80% of our Wave Light Sport Aircraft model’s DNA," said Paul. "This positions us well down the road of developing shared technology, components and tooling, R&D, materials, manufacturing processes, techniques, and facilities that we have been refining over the years for our LSA."
"Developing an eVTOL with amphibious capabilities opens possibilities not yet explored in this space, and with the New Zealand government leading the world from a regulation standpoint, New Zealand is on track to be the first country to allow approved manned eVTOL passenger flights."
Vickers Aircraft is working closely with the Civil Aviation Authority of New Zealand (CAANZ) throughout the development of the Wave LSA and eVTOL aircraft variants.
As you can see yourself, the proposed Wave eVTOL uses the multicopter approach with wing sections. They aren't the first to do this (
Anticipating a question readers might pose, I asked Paul if this new direction meant he was easing away from the fixed wing LSA.
"The initial design for the Wave was always to have a core base that can be used on a number of different models; the second in this range is the Wave eVTOL," Paul explained. "With facilities and technical ability already established [and with] wider government and regulatory support for the development of next generation aircraft in New Zealand, we feel confident in having a proof of concept ready by 2020."
The Wave LSA seaplane will come much sooner though Vickers Aircraft is cautious about promises given what they've observed from other companies in this space. He offered no update on the fixed wing model.
However, he is enthusiastic about using years of hard work to bring a one-design company closer to the family of aircraft he always foresaw.
"The beauty of the Wave eVTOL is that it can be developed in parallel with [our] LSA, enabling us to maintain our schedule," said Paul. "Both models will share everything from components and tooling to ergonomics and storage, as well as manufacturing procedures and material allowables that will combine to result in a rapid development cycle."
To further communication on the new aircraft in planning, an organization called 
Two years ago at my favorite European airshow, 
The truly good news for Yankees who might want to own such a creation is that Sportair USA boss Bill has placed an initial order. For a tiny company, such a launch customer greatly increases the likelihood that this unqiue entry will makes it way into American skies. Of course, Europeans also recognize both the F4U resemblance and the coolness of this design effort.
While fabric covered (also for lightness), Jörg refers to his internal carbon fiber tube structure as "a unique carbon-spaceframe technology." He added, "This property right-protected technology combines high strength with an unequaled low weight."
Seeking a very low weight is partly a maneuver to steer clear of tough certification rules via the Part 103 / 120-Kilo Class / SSDR 
A light design permits Jörg's design objectives. "Due to the light weight of the structure we were able to include all the ingredients for a high performance aircraft: outstanding aerodynamics, a strong engine with a big, efficient propeller, a short and aerodynamic landing gear, as well as effective flaperons."
The carbon-spaceframe is effective, resulting in a calculated +9 and –6g ultimate load strength. "Furthermore," Jörg said, "the complete cockpit area is constructed as a Kevlar-reinforced safety cell." A ballistic parachute will further enhance safety.

I will cover many aircraft stories, but allow me to take the most recent first: flying the brand-new Rotax 915iS and comparing it to the 912iS, although not in the same airframe. Other than official Rotax pilots and select airframe builders, we were among the first to experience the powerful new engine from the world’s leading producer of engines for light aircraft.
Fuel consumption was higher than I expected, but speed was also higher. To get below 3 gph, a surprisingly low consumption rate, speed dropped below 100 knots true or 85 indicated. When zipping along faster than 170 miles an hour true, consumption rose to the 7-9 gph range.
The 915iS fuel injected, turbocharged, and intercooled engine can produce 141 horsepower for five minutes, then sustain 135 horsepower indefinitely.
Once at altitude, Christian demonstrated use of the throttle and prop controls — this was not a single lever control airplane — to adjust for speed or economy. As you can see in the contrasting Stock Box images, we saw as low as 2.8 gallons per hour resulting, of course, in lower speed flight.
Christian demonstrated that you can move the throttle and prop control without my experience of adjusting each very cautiously and slowly. Christian jockeyed them around liberally without detriment. A key reason this is possible is because of liquid cooling versus my older experience in air-cooled legacy engines, for example, in a Cessna 182 Skylane.
A fellow aviation journalist — a pilot of 300 different aircraft — Dave Unwin felt the 915 started "softer." He also felt it seemed to run slightly smoother. Rotax engine experts felt most of this is attributable to software and the same code can also be applied to the 912iS.
Yet for those who yearn for more power or are building an aircraft of higher capabilities, the 915iS is going to be a welcome powerplant. It does come with a few costs, as did the 912iS fuel injected engine compared to the 912ULS carbureted engine.
Marc Becker summarized, "The 915iS is about 12 kilos (26 pounds) more for the engine only; 40-50 more pounds when installed and about €3,000 ($3,750 at today's exchange rates) more than the 914." It is significantly more than the 912iS, as you should expect for an engine with substantially more power and the ability to use that power up to higher altitudes.
Fuel needs of both 915iS and 912iS are essentially the same. Thomas Uhr, head of Rotax's Austria plant and a longtime engine expert and enthusiast — and also a pilot — advises the highest octane auto fuel, preferably without alcohol, to get the most power and best results.
Immediately following 
Igor appears to achieved his goal.
SD Planes' show aircraft at Aero 2018, its first production example, is powered by the Rotax 912 ULS2 engine, which should yield sprightly performance from this very light aircraft. SD-2 weighs in at a lean 578 pounds. Given a 1,320 maximum takeoff weight, it can carry 125% of its empty weight. Even with full fuel (26 gallons) SD-2 can carry a payload slightly greater than its empty weight. Few two seaters can match that feat. It's largely wood structure is tough enough to handle a +5/-3 g limit load.
SD-2 can run at LSA speeds of around 120 knots and stalls at a low 34 knots, very close to the 4:1 holy grail of maximum to minimum speed.
Similar to SD-1 Minisport, SD-2's fuselage employs primarily a wood truss design although the wing has a carbon main spar with composite integral fuel tank. Covered with thin (1.5 mm) plywood, SD-2 is a genuine composite aircraft. Wingtips are built of glass and PVC foam sandwich, but wood does most duty as it is low cost and proven. Big slotted flaps are made of carbon with PVC foam sandwich while counterbalanced ailerons are built of plywood and XPS foam. Wings attach to the fuselage using two main and two auxiliary pins that Spacek said allows disassembly in only 10 minutes.
Side by seats seats are equipped with in-flight adjustable pedals with 6-inch (150 mm) range, that the designer said will accommodate someone 6.6 feet tall (200 cm) tall. Inside, SD-2 is spacious with a 46-inch (117 cm) cockpit width at the shoulders. A fairly roomy baggage compartment holds 44 pounds (20 kg) behind the seats.
