During a steep turn, what must be applied to prevent an increase in bank?

During a steep turn, pressure to the aileron controls is essential to maintain the desired bank angle. As the aircraft enters a steep turn, an increase in load factor occurs due to the increased centripetal force, which can inadvertently lead to an increase in bank if not properly managed.

Applying outward pressure on the ailerons helps to counteract any tendency for the bank to increase further. This requires continuous coordination and input from the pilot to ensure the aircraft maintains a steady bank angle while not exceeding the aircraft's limitations.

Maintaining a constant bank angle during a steep turn is crucial not just for flight performance, but also for the safety of the flight, as exceeding the maximum bank or load factor can lead to a stall or loss of control. Therefore, it's important for pilots to be aware of the necessary aileron inputs required to stabilize their turn.
