System and Method for Rotorcraft Collective Power Hold

A rotorcraft, comprising:

• a collective control;
• a collective position sensor connected to the collective control, wherein the collective position sensor is operable to generate collective position signals indicating a position of the collective control;
• a flight control computer (FCC) in signal communication with the collective position sensor and operable to provide a power hold for the rotorcraft in response to a power hold activation signal and further in response to a first one of the collective position signals indicating that the collective control is overdriven, wherein the FCC is further operable to determine a power setting for the power hold and one or more operational limits associated with the power hold;
• a collective trim motor connected to the collective control and in signal communication with the FCC;
• and
• one or more flight control devices connected to the FCC and operable to control flight of the rotorcraft in response to a flight control device control signal received from the FCC;
• wherein the FCC is operable to determine a flight parameter for the one or more flight control devices according to a relationship between the one or more operational limits and one or more operational parameters indicated by one or more sensor signals received at the FCC, wherein the FCC is further operable to determine a pilot control setting according to the flight parameter and generate a collective set command according to the pilot control setting;
• wherein the collective trim motor is operable to move the collective control according to the collective set command;
• and
• wherein the FCC is operable to generate the flight control device control signal according to a second one of the collective position signals, and to send the flight control device control signal to the one or more flight control devices.
