What are "flaps" on an aircraft?

Flaps are movable surfaces located on the wings of an aircraft that play a crucial role in enhancing lift during takeoff and landing phases of flight, particularly at lower speeds. When deployed, they extend outward and downward from the trailing edge of the wings. This alteration in wing shape increases both the camber and the surface area of the wing, allowing for greater lift generation even when the aircraft is flying at lower airspeeds.

This ability to increase lift is essential for enabling an aircraft to take off and land safely, as it allows pilots to operate the aircraft at slower speeds without stalling. The use of flaps enhances the performance characteristics of the aircraft during critical phases of flight, making them a vital component for safe operation in various conditions.
