What is the primary effect of increasing the bank angle during a turn?

The primary effect of increasing the bank angle during a turn is that it increases the load factors on the wings. When an aircraft banks to turn, the lift vector tilts along with the aircraft. To maintain a level turn, the aircraft must generate additional lift to counteract the increased load due to the banking angle. This is because as the bank angle increases, a portion of the lift is used to provide centripetal force instead of solely opposing gravity. Consequently, the load factor, which is the ratio of the lift generated to the weight of the aircraft, increases as the bank angle rises. This phenomenon is essential for pilots to understand, as it requires adjustments in airspeed and thrust to ensure that the aircraft remains in a safe operating envelope during the turn.
