A wide range of people sat in a room used all day long by the ASTM Committee that develops the LSA certificate standards. Apparently sitting in a room all day — while the sun shown brightly and the flying would have been great — was not enough punishment for this hard working crowd. Indeed, nearly 30 persons willingly stayed into the evening. What drove such dedication? Electric-powered aircraft. *** The G-30 assembled to work at forming the Electric Aircraft Development Alliance (EADA), a brand new industry organization specifically aimed at electric-powered aircraft. Representatives came from Sikorsky, Yuneec, Pipistrel, Sonex, Alternair, Electra One, Cessna, Bye Aerospace, Lockwood Aircraft, Embry Riddle, FAA, EASA, LAMA, and others. LEAP, the Lindbergh organization, lent energy to help assemble the group and, indeed, they drew a number of people that had not traveled to Tampa, Florida for the ASTM meeting.

Posting from Istanbul, Turkey where I’m on vacation with my family, but just couldn’t wait another day to talk a bit about what most everybody in aviation’s been talking about these last several days: the CAFE Green Flight Challenge (GFC). *** History was made when the Pipistrel Taurus Electro G4 twin-fuselage electric-powered aircraft carried four adults, around 1000 lbs. of batteries, one electric motor with a bit prop, and a lot of engineering and piloting savvy to victory in the GFC. They earned themselves $1.35 million in the process. Huge and well-deserved congratulations to Pipistrel!But for my money, the deeper story is not just that they flew off with the biggest aviation dollar prize ever, or even that they accomplished the task of flying 200 miles on one battery charge while also averaging more than 100 mph for the entire flight, or that they did it while “burning” the equivalent of 1 gallon of gas per passenger, or four gallons total…but…that they accomplished all that yet consumed the equivalent of around 1/2 gallon of gas per passenger!

Anyone still in doubt that we’re in the midst of the birth of electric flight need look no further than this story, just posted today on the online tech zine Gizmag.Pascal Chretien, an enterprising electrical/aerospace engineer and chopper pilot, made the world’s first fully electric helicopter flight in the prototype he designed and built almost entirely by himself… in just 12 months! Hang glider and ultralight trike pilots will delight in hearing a weight shift control system is involved. *** For me, the big story here is once again we see that innovation lives, not just in megabuck corporate and government R&D departments but in the garages of individual megabrains as well…as it always has and we can expect always will.Chretien, in making his 2 minute, 10 second test eggbeater flight, threw whipped eggs in Sikorsky’s face since that aviation giant’s well-funded electric project, in development for some time now, has yet to fly.

A crack team of aeronautical whizbrains in the Institute of Aircraft Design at the University of Stuttgart, Germany has just passed its second important milestone in less than two months: its electric aircraft eGenius just flew more than two hours at more than 100 mph. *** Not by coincidence, that’s exactly the kind of performance that will be required to take $1.3 million top prize in the recently postponed (until September 25) CAFE Green Flight Challenge.  *** The GFC will award the prize money to the aircraft that can fly 200 miles at greater than 100 mph on the equivalent of one gallon of gas per occupant. The per occupant proviso is significant…and EGenius carries two people, so it can use enough batteries to store two gallons worth of energy.  *** That’s a lot of batteries given the current relative inefficiency of energy storage of batts vs.

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.

Although this isn’t an LSA story per se, it comes out of Flight Design, the top-notch, top-selling LSA company in America, so I thought you’d be interested to know the company debuted its C4 4-seater at Aero last month and just came out today with some pricing and delivery numbers along with some specs. *** Perhaps the most interesting number to me is the $250,000 “target” price for the American market, along with a €220.000 price for Europe and the rest of the world outside the U.S. *** When’s the last time we saw a new, state-of-the-art 4-seat airplane at a price close to that? *** Also noteworthy is the minimal disparity between the overseas and U.S. prices, reflecting the company’s desire to minimize (yea verily, to almost negate!) the currently soaring euro/dollar exchange rate imbalance. *** Some interesting details about the all-carbon fiber composite airplane: • Engine choice: two engine options to best suit fuel availability and cost in the owner’s region: either a traditional aviation engine that can run on auto fuel, or a turbo diesel engine that burns Jet A fuel.
