Winch launching requires about 4,000 feet of light-weight wire or composite cable. When the glider pilot is ready a wing runner levels the wings of the glider and signals the winch operator near the cable drum to start reeling in the cable. Quite quickly the glider is flying on its own and flying skywards at a 45 degree angle. The whole launch is often done in about two minutes when the cable is released by the glider. A small parachute is deployed when the cable is released that gently guides it to the ground. It is then stretched out to launch the next glider.
