Aviation work began in 1971 and has since built many
thousands of motorgliders, lightplanes and other aircraft.
Recent aircraft include the G 103 Twin III and
G 109 series of gliders/motorgliders (production now
ended), piston-engined G 115 two-seat lightplane
(some versions suited to training and aerobatics; first
flown November 1985), GF
GF 200
200 pusher piston-engined
and pressurised 4/5-seat lightplane (first flown November
1991, with six-eight seat versions with piston and
turboshaft engines anticipated as GF 250, GF 300, and
GF 350), turboprop-powered G-520 Egrett and Strato
1 high-altitude and long-duration research platforms
capable of carrying different electronic payloads in 12
separate compartments (first flown June 1987 in G-
500 Egrett form), and the most recent G-850 Strato
2C high-altitude and long-duration atmospheric/ stratospheric/
climatic research aircraft with a unique compound propulsion system using two turbocharged
piston engines and two gas generators (first flown
March 1995).
