1. A method for controlling an aircraft during flight, the method comprising:
determining that a flight parameter of the aircraft is indicative of an out-of-flight-envelope situation of the aircraft while one or more aspects of operation of the aircraft are controlled using a flight control computer;
while the aircraft is in the out-of-flight-envelope situation:
evaluating one or more control commands output by the flight control computer and associated with the flight parameter;
when the one or more control commands are indicative of the flight control computer attempting to cause the aircraft to return within its flight envelope, allowing the flight control computer to continue controlling the one or more aspects of operation of the aircraft; and
when the one or more control commands are indicative of the flight control computer not attempting to cause the aircraft to return within its flight envelope, preventing the flight control computer from controlling the one or more aspects of operation of the aircraft.
