【News to watch】What is a flap?

Flap refers to a movable wing device on the edge of the aircraft wing. Its main function is to improve the lift coefficient of the aircraft wing and provide additional lift for the aircraft. Flaps can be installed on the trailing edge or leading edge of the wing, and can be deflected downward or/and slid backward (forward) to increase the curvature of the wing.
