What are the max bank and airspeed tolerances for steep spirals?

The maximum bank angle and airspeed tolerances for steep spirals are critical for maintaining control and ensuring safety during the maneuver. The correct answer indicates that the maximum bank angle is 60 degrees with an allowable airspeed variation of plus or minus 10 knots. This reflects the general parameters used in training and regulation regarding steep spirals, as this specific combination of bank angle and airspeed provides a balance between maneuverability and the risk of loss of control.

When performing a steep spiral, pilots must exercise care to ensure they do not exceed the maximum bank angle, as greater angles can lead to increased load factors and complicate recovery. The airspeed limits ensure that the maneuver remains within a manageable envelope, preventing stall conditions or structural stresses on the aircraft. This combination emphasizes safety and operational control, highlighting how pilots need to adhere to specified limits for effective maneuver execution.
