What role do trailing edge flaps serve in aircraft?

Trailing edge flaps play a crucial role in enhancing the aerodynamic performance of an aircraft during critical phases of flight, particularly during takeoff and landing. When deployed, these flaps increase the curvature of the wing, which in turn increases the lift generated at lower speeds. This enhanced lift capability allows the aircraft to safely take off and land, even in shorter distances or at lower airspeeds, which is essential for optimal performance during these phases.

The design of trailing edge flaps is such that they also enable a higher angle of attack without causing a stall, further contributing to their effectiveness in increasing lift. The ability to effectively manage lift is vital for the safe operation of an aircraft, and this is why trailing edge flaps are integral to the flap system on many commercial and general aviation aircraft.
