What is the main function of the ailerons?

The main function of the ailerons is to control the roll of the aircraft. Ailerons are located on the outer wings and operate in a differential manner; when one aileron moves up, the other moves down. This movement creates a difference in lift between the two wings, causing the aircraft to roll to one side or the other. By altering the aircraft's roll, pilots can effectively execute turns and maintain level flight. Understanding the role of ailerons is essential for effective aircraft handling, as they play a crucial part in managing the aircraft's lateral stability and maneuverability.
