Abstract:
A method for operating a rotorcraft includes providing a power hold by performing monitoring one or more operational parameters of the rotorcraft during flight, determining whether operational parameters need adjustment according to a relationship between the operational parameters and operating limits associated with a power setting for the power hold, and determining a flight parameter for one or more flight control devices of the rotorcraft in response to determining that the operational parameters need adjustment. Providing the power hold further includes sending a position set signal to a trim assembly of the rotorcraft to set a first position of a pilot control connected to the trim assembly according to a pilot control setting generated according to the flight parameter, and controlling a flight control device control according to a second position of the pilot control.
