Introduction to Glider Flying > Components and Systems > The Empennage > Tow Hook Devices

An approved towhook is a vital part of glider equip-ment. The towhook is designed for quick release when the pilot applies pressure to the release handle. As a safety feature, if back pressure from either getting out of position during the tow or over running the towrope, the release will automatically open. Part of the glider pilot’s preflight is to ensure the towhook releases prop-erly with applied forward and back pressure.

The glider may have a towhook located on or under the nose and/or under the center of gravity (CG), near the main landing gear. The forward towhook is used for aerotow. The CG hook is used for ground launch. If the glider has only a CG hook, it may be approved for aero-tow in accordance with the Glider Flight Manual/ Pilot’s Operating Handbook. [Figure 2-6]
