At what bank angle should a turning power-off stall be performed?

The correct bank angle for performing a turning power-off stall is around 20 degrees. This angle is significant because it simulates a more realistic scenario that a pilot may encounter during flight when transitioning from straight flight to a turn.

In a real-world application, many pilots operate in a setting where turns are common, and using a 20-degree bank provides an adequate balance between stability and the onset of stall conditions. At this angle, the aircraft can still maintain reasonable control authority while allowing the pilot to understand how the aircraft responds as airspeed decreases.

Furthermore, a 30-degree bank might result in more pronounced stall characteristics and can introduce unwanted complications during the stall recovery process, whereas a 10 or 15-degree bank may not sufficiently demonstrate the critical aspects of stall recognition and recovery in a turn. Therefore, a bank angle of approximately 20 degrees is preferred to effectively teach or demonstrate the dynamics of a power-off stall while ensuring safety and control.
