UG212 RTP SLOT A type of split flap that slides backward along curved tracks that force the trailing edge downward, increasing chord and camber without affecting trim or requiring any additional mechanisms. The entire leading edge of the wing rotates downward, effectively increasing camber and also slightly reducing chord. Any flap that allows air to pass between the wing and the flap is considered a slotted flap. Extending the wing flaps increases the camber or curvature of the wing, raising the maximum lift coefficient or the upper limit to the lift a wing can generate.|Open Casebook.
