What is the function of ailerons during a turn?

The function of ailerons during a turn is to create differential lift, which allows the aircraft to roll into the turn. Ailerons are hinged flight control surfaces located on the wings of an aircraft. When the pilot moves the control yoke or stick, one aileron goes up while the other goes down. The aileron that goes up decreases lift on that wing, while the aileron that goes down increases lift on the opposite wing. This differential lift causes the aircraft to roll towards the wing with the descending aileron, initiating a turn.

Understanding the role of ailerons is crucial for pilots, as it directly influences the aircraft's ability to bank and change direction. Proper aileron use combined with coordinated use of rudder and elevator helps maintain control of the aircraft's attitude during turns.
