Abstract

The powered sailplane gives its pilot maximum freedom of the skies with a minimum of the trouble and waiting usually associated with gliding activities. WINDEX 1200 is primarily a high-performance sailplane, but its concept of a low-drag fin-mounted engine installation and a variable pitch propeller turns it into an efficient touring aircraft with a cruising speed of 210 km/h ( 130 mph) at 50% power. In addition the airframe is stressed for aerobatic maneuvers and designed to JAR 22 A. This may be exploited accordingly or could be regarded as an extra safely margin in normal flying.
