What must pilots be prepared to do during recovery from an airplane upset?

Utilizing full control authority is essential during recovery from an airplane upset because it allows pilots to maximize their ability to stabilize the aircraft effectively. During an upset, the aircraft may be in a state where it is not flying as intended, potentially involving unusual attitudes or conditions that challenge the pilot's control. By using full control authority, pilots can take full advantage of the flight controls available, including ailerons, elevators, and rudders, to regain a normal flight attitude and restore stability.

To successfully manage an upset scenario, it is crucial that pilots do not hold back their inputs or limit their control usage. Proper and assertive use of the flight controls enables a quicker return to normal flight conditions and reduces the risk of escalating the situation. Being trained to react decisively ensures that pilots can act swiftly and confidently in response to the conditions they are facing.

This approach is supported by upset recovery training that emphasizes the importance of immediate and effective control inputs to counteract the effects of the upset and return the aircraft to stable flight mode.
