The increase in camber also increases the wing drag, which can be beneficial during approach and landing, because it allows the aircraft to descend at a steeper angle. For most aircraft configurations, a useful side effect of flap deployment is a decrease in aircraft pitch angle which lowers the nose thereby improving the pilot's view of the runway over the nose of the aircraft during landing. Another side effect however, depending on the type of flap, location on the wing and deployment speed during their extension, is that the flaps will cause the indicated (or relative to the unchanged airfoil) angle of attack to lower within a short time due to an increase in nose-down pitching moment which is characteristic to all trailing-edge flaps, as well as leading-edge flaps, then followed by a nose rise (pitch-up) due to the increase in lift, thus obscuring the pilot's view of the runway if no action is taken over the pitch inputs.
