The aerotow starts with hooking up a rope to the tow hook on the nose of the glider. When the glider and towplane pilots are both ready to go another person raises the wing tip of the glider, levelling the wings and uses hand signals to tell the towpilot to begin the launch. The glider and towplane only have to accelerate a few feet before the wing runner can let go, and the aerotow is on its way. The glider and towplane fly in formation until the glider releases the tow rope at the desired launch height. Typically this is 2000 feet above the ground.
