Instrument panel indicator lights report fully extended, fully retracted, and intermediate wing positions. Both the flaps and the wing extensions have the same maximum extend speed limitations. Airspeed sensing limit switches prevent inadvertent extension at high speeds. The appropriate flap and wing extension airspeed range is marked on the airspeed indicator. Small wing area improves ride quality in rough air.
Hangar space is minimized.
Small aileron area provides light stick forces at high speed. Provides protection from ice accumulation on half of the wing span until needed for landing. Simulates high performance jet aircraft for economic pilot training. Can be used as test vehicle for full scale aerodynamic testing of new wing geometries on the extension sections. Drag reduction improves speed and efficiency.
