What is the purpose of using ailerons during a turn?

The primary purpose of using ailerons during a turn is to maintain the bank angle. When an aircraft enters a turn, the pilot uses ailerons to tilt the aircraft's wings, which creates a bank. This banking allows the aircraft to turn. To keep the desired bank angle consistent throughout the turn, ailerons must be adjusted accordingly. If the ailerons were not employed, the aircraft could either roll back to level flight or increase its bank angle uncontrollably.

Maintaining a specific bank angle is crucial for ensuring a smooth and controlled turn, allowing the aircraft to follow the desired flight path without excessive altitude loss or gain. Other controls, such as the rudder and elevator, work in conjunction with the ailerons to maintain overall flight stability and control during turns.
