Abstract: A flight control computer (FCC) for a rotorcraft includes a processor and a non-transitory computer-readable storage medium storing a program to be executed by the processor, with the program including instructions for providing main rotor overspeed protection. The instructions for providing the main rotor overspeed protection include instructions for monitoring sensor signals indicating a main rotor RPM, determining a target operating parameter, determining one or more flight parameters in response to a relationship between the main rotor RPM and the target operating parameter indicating a main rotor overspeed condition. Determining the one or more flight parameters includes determining a setting for a flight control device of the rotorcraft that changes the main rotor RPM, controlling positioning of a pilot control according to the flight parameters, and controlling the flight control device of the rotorcraft according to positioning of the pilot control.

Abstract: A method of operating a rotorcraft includes receiving multiple first height data signals from multiple first height sensors on the rotorcraft, wherein the first height sensors measure height using a first technique, receiving multiple second height data signals from multiple second height sensors on the rotorcraft, wherein the second height sensors measure height using a second technique that is different than the first technique, determining a first height signal from the multiple first height data signals based on a selection scheme, determining a second height signal from the multiple second height data signals, selecting the first height signal or the second height signal to determine a selected height signal, and generating a flight control signal and controlling operation of the rotorcraft according to the flight control signal, the flight control signal based on the selected height signal.
