The Archaeopteryx is more than just a good word for spelling bees, it’s a high-end hang-glider – and now, depending on your bankroll and perspective, a low-end electric motorglider.  Its low weight (54 kilograms or 118.8 pounds in its most basic state) and high performance (around 25:1 lift-to-drag ratio) has helped this Swiss marvel achieve things like the 498 kilometer (308.76 mile) goal flight by Peter Eicher in Australia last October; or a 407 kilometer (252.34 mile) flight around the Swiss Alps in 2012. A flier can hop off a hill with the lightest and most basic form of Archaeopteryx, which features self-connecting controls, a rocket-deployed full-airplane rescue system, and a wheel brake.   Pilots wanting less local soaring and the …

This represents a significant milestone in gliding history, which marks a new age of technology!” We hope this breakthrough in Germany encourages our own Federal Aviation Administration to review their schedule for electric aircraft certification.  Such rule making would allow sales of existing electric motorgliders and   light aircraft and encourage others to step up development of these alternatives to fuel-burning lightplanes. The Type Certificate gives some clear ideas of the technology incorporated in the very …
