Getting the Hang of ItWinds are important to hang gliding and techniques vary according to the terrain and the strength of prevailing winds. Usually, the beginner learns to take off by running down a slope into a slight headwind, holding the kite level and then pushing out on the frame to raise the nose until the glider begins to lift off by itself. It takes a wind of five to 12 mph to become airborne and an average airspeed of 20 mph to remain aloft
