Description

A Flight Control Lock (sometimes referred to as a Gust Lock) is a means by which control surfaces on an aircraft not in flight can be prevented from random movement caused by wind, jet blast or propeller wash and thus possible damage to the surface, attachment points or control system. Most aircraft have some means of preventing, or at least limiting, flight control surface movement when parked but some light aircraft manufacturers recommend rather informal methods of achieving locking of the aileron and elevator controls by, in one case, "looping the safety belt through the control wheel and pulling it snug."
