While some producers add four seaters (or more) to their LSA line, others have taken a different approach. The number of attractive new single-place models at Aero was surprising as most pilots seem to believe two seats are the minimum. *** However, for years AOPA surveys have shown the average occupancy of a GA aircraft — most of which have four seats and several models have more — is, wait for it… 1.6 persons. Given all those extra seats the 1.6 figure means a significant number of all flying is done solo. So, why pay for the extra seats when you fly solo frequently? Cost of acquisition and operation can be dramatically lower in a single seater, and you have no one else to please (or worry about) except yourself. *** I’m sure I didn’t see them all — Aero features a huge display of aircraft — but here’s a few of the new single seaters I discovered.

Most of what our media reports about Iran is bad: Islamic militants. Contested elections. Brutal suppression of dissent. Nuclear ambitions. What we don’t hear is about the country’s light aircraft producers. Then consider Malaysia. Do you think of that country relative to aircraft production? Do you think of it in any way? My guess is most Yankee aviators haven’t given either country much thought (except maybe in a negative context). *** Yet here is Free Bird. An article appearing on Iran’s PressTV began, “Iranian aviation researchers have designed and built an all-composite ultralight aircraft to meet the country’s training, border control, surveillance and recreational needs.” The researchers are evidently employees of manufacturer H. F. Dorna Company, which “was established in Tehran in 1988 as a private company specializing in design and manufacture of light-sport aircraft.” *** Managing director of H. F. Dorna, Yaghoub Entesari, was reported as saying, “[Free Bird’s] full composite structure conforms to ASTM technical standards and falls under the micro-light category under Iranian law.” Free Bird is said to fly more than 500 miles with a maximum airspeed in level flight of more than 150 mph (which is beyond FAA’s LSA rules).

As the battle rages on regarding a replacement fuel for 100 LL avgas, sport aviation enthusiasts already have another, cheaper fuel option. The best news is they potentially have an enormous support group (even bigger than Facebook, if you’ll permit that comparison). Here’s what blogger Kent Misegades wrote… *** “Consider these numbers:  According to GAMA, there are approximately 165,000 piston-engine aircraft registered today in the United States. Since 1982, some 65,000 autogas STCs have been sold by Petersen Aviation and the EAA. A growing part of the GA fleet, America now has around 2,000 new SLSA (and many thousands more ELSA) registered. Nearly all of these use engines designed to run on autogas. Fuel is sold at approximately 3,500 FBOs on the 13,000+ airports registered in the country. Autogas is currently sold at just 100 of these airports.” (Talk about your missed opportunities! —DJ). *** “By contrast, in 2006, the U.S.

As I write an article on the current state of electric flight worldwide, sad word comes that prolific, talented German aeronautical engineer Martin Wezel has died in the crash of the prototype Yuneec International E1000 electric airplane. *** Wezel’s company, Flugzeugtechnik Wezel, was well respected for its gliders and microlights, which included the Sting and Sirius SLSA. His Apis and Viva designs were also being developed by Yuneec for electric power. The E1000 design may also have been Wezel’s. *** A new, tandem-motored four-seat design, it was being developed for market by Yuneec but also to compete in the NASA CAFE Green Flight Challenge, the $1.65 million-prize competition that’s coming up in July. *** E1000 was also entered in EAA’s upcoming Electric Aircraft Competition (Oshkosh 2011 in late July). Not evident at this point is whether another E1000 was built or will be tested.

Weight shift instructor and FAA Designated Airworthiness Representative (DAR) Terri Sipantzi wrote an excellent editorial about the FAA’s plan to start inspecting new SLSA or new companies producing LSA. Terri’s piece was well written and accurate. He quoted me but I find it surprising to be the only one publicly talking about this matter even though FAA has said (at AirVenture 2009) that they would be doing more inspections. This is not new information. I am merely beating the drum louder as FAA gets closer to doing what they said they would do. *** Yet Terri left out an important point… Industry could provide such oversight. In fact, I believe industry oversight could be the more effective method to increase compliance and potentially therefore safety, which — to put a fine point on it — is the ultimate goal of certification schemes. All these parts — standards, certification oversight, manufacturing best practices, quality control systems, third party audits — have one purpose: Safety.
