What is the recommended bank angle when flying in a holding pattern?

In a holding pattern, the recommended bank angle is primarily determined by the need to maintain a specific turn radius while also ensuring a safe and comfortable environment for passengers and crew. A bank angle of 25° is often recommended for heavier aircraft because it strikes a good balance between maintaining the required rate of turn and managing the aircraft's load factors efficiently.

The phrase "or at a rate of 3° per second" provides pilots with additional flexibility to manage their turns, particularly when flying in varied conditions such as turbulent air or when the aircraft is under heavy load. However, the emphasis is on using the lesser bank angle if the required bank for given conditions indicates a smaller angle, as safety is paramount.

This understanding of banking requirements is applicable to maintaining a properly controlled and standardized flight in a holding pattern, thereby minimizing the risk of overstressing the aircraft or making the maneuver uncomfortable for those onboard.
