12.56.2 Show how CL varies with use of flaps and control surfaces
The coefficient of lift (CL) is a measure of the lift generated by an aircraft's wings.
The CL varies with the use of flaps and control surfaces in the following ways:
Flaps are used to increase the lift generated by the wings at low speeds, such as during takeoff and landing.
By increasing the surface area of the wing, flaps increase the CL of the wing. T
his allows the aircraft to take off and land at lower speeds, which can improve safety and reduce the length of the runway required.
