What is the maximum angle of bank allowed during a steep turn?

In aviation, a steep turn is generally defined as a turn that exceeds a 30-degree bank angle. However, in certain flight operations and training exercises, particularly in specific aircraft and under controlled conditions, a maximum bank angle of 45 degrees may be permitted.

A 45-degree bank angle allows for effective maneuvering and greater performance while still providing an adequate safety margin under normal flight operations. This angle facilitates maintaining altitude while turning; however, it also increases the load factor on the aircraft to about 1.4 Gs. Pilots are trained to execute steep turns while managing this increased demand on the aircraft systems and ensuring that the aircraft remains within its performance limits.

Understanding the maximum angle of bank during steep turns is crucial for safe flight management, ensuring that pilots can maximize maneuverability without exceeding the structural limitations of the aircraft or compromising safety.
