Abstract:
A control system having at least a first control loop and a second control loop for determining the upper and lower cyclic limit increments due to the contribution of collective pitch in rotorcraft based at least on nacelle angle and airspeed. The aircraft is more robustly controlled by generating flight control limits for the aircraft, modifying the flight control limits based upon impending hazardous flight conditions, and adjusting a size of a flight control envelope as the aircraft transitions between non-hazardous flight conditions and hazardous flight conditions.
