What indicates a successful stall recovery maneuver?

A successful stall recovery maneuver is indicated by the aircraft's nose being level with the horizon and maintaining coordinated flight. This post-stall recovery position demonstrates that the pilot has effectively regained control of the airplane, allowing it to resume a stable and powered flight configuration.

During a stall recovery, it is crucial to return the aircraft to a normal flight attitude and ensure that all flight controls are functioning together harmoniously. Achieving a nose-level position indicates that the pilot has managed to promptly lower the nose of the aircraft and prevent further loss of lift. Coordinated flight ensures that the wings are balanced and not contributing to any additional yaw or unwanted roll tendencies, which are common during and immediately after stall conditions.

The other options involve scenarios that do not reflect the correct recovery from a stall. For example, a rapid descent may suggest continued loss of control rather than recovery, full throttle without a proper pitch adjustment could lead to further stall conditions, and banking during recovery can exacerbate the stall situation, making it critical to level the wings first before any turns are made. Therefore, the successful recovery is characterized by re-establishing level flight and control.
