The ASW 20 is an FAI 15-meter Class glider designed by Gerhard Waibel and built by Alexander Schleicher. The ASW20 first flew in 1977 and was an instant success, winning numerous world and national championships. Dick Johnson reported that the ASW20 was the first 15 m glider to demonstrate a measured L/D in excess of 40/1. The ASW-20-B is known as a very pleasant handling glider in most respects. The landing flaps (55° in early models, 38° in later models), in conjunction with very effective air brakes, allow the pilot to make exceptionally steep approaches at slow speeds, permitting very short landings when required. #gliding #soaring #sailplane #glider #aviation #globalgliding #flying #gliderpilot #pilot #plane #sailplanepilot #asw20
