Flap

A movable surface at the trailing edge section of the wing used to change the camber of the airfoil thus generating more lift at lower speed sometimes used to control angle of descent through provision to deflect upward offering greater speed over the ground in transitioning between thermals to reduce time spent in a sink. Most usually awing trailing-edge movable surface which can be deployed partially to increase lift, or completely to increase drag.
