Any surface usually forming part of the rear portion of a wing, adjustable in flight, the primary function of which is to increase the lift.


Wing flaps are hinged or sliding surfaces mounted at the trailing edges of wings and designed to increase the camber of the wings. As explained previously, the purpose of flaps is to increase the lift of the wing at a particular speed and angle of attack and also to increase the drag. Wing flaps are particularly useful in the approach to a landing to increase the gliding angle and decrease the landing speed of an aircraft.
