The National Aeronautic Association has certified the July 13 record for the University of Maryland’s human-powered helicopter called Gamera. It achieved liftoff and hovered for 11.4 seconds, setting U.S. records for flight duration and for flight duration by a female pilot. ( Watch a video of the flight.).
It was designed and built by graduate and undergraduate students at the University of Maryland's A. James Clark School of Engineering and piloted by biology student Judy Wexler.
The NAA has submitted its findings to the Fédération Aéronautique Internationale (FAI) for evaluation as world records in the same categories. The process may take two to three months. A May flight is also under evaluation by FAI.
Now the question is what to do next. Do you set another, better record, or do you just go for it all, represented in this case by the Sikorsky Prize. The American Helicopter Society’s Sikorsky Prize requires a human-powered helicopter to hover for a full minute, and to go as high as three meters, all while remaining in a 10-square-meter area. If you watch the video, you’ll see that the latest record-setting flight hit a chair after going airborne and drifting from its launch area.
AOPA Pilot Senior Editor Alton Marsh has been a pilot since 1970 and has an airline transport pilot certificate and instrument and multiengine flight instructor certificates, aerobatic training, and a commercial seaplane certificate.
Beringer Wheels and Brakes announced the availability of several types of aircraft wheels on July 29 at EAA AirVenture in Oshkosh, Wisconsin, and said a new anti-groundloop tailwheel design is forthcoming.
The widespread presence of angle-of-attack indicators in general aviation aircraft could reduce fatal loss-of-control accidents caused by inadvertent stalls, said the FAA.
Flight Design says production and testing of its four-seat C4 is on target despite the ongoing conflict in Ukraine.
