What is the function of the ailerons?

The function of the ailerons is to control roll around the longitudinal axis of the aircraft. They are typically located on the outer trailing edges of each wing and work by changing the lift characteristics of each wing independently. When one aileron is deflected upward, it decreases lift on that wing, while the other aileron deflected downward increases lift on the opposite wing. This differential lift causes the aircraft to roll in the direction of the wing with the downward-deflected aileron, allowing the pilot to maneuver the aircraft effectively during turns and other flight conditions.

Understanding this function is crucial for pilots, as controlling roll is essential for maintaining stability and maneuverability in flight. This operation primarily influences how the aircraft banks and turns, making it an integral part of the overall flight control system.
