Abstract
A flight control system includes a flight control computer operable in a flight state and a ground state. A high demand trim relief logic is operable by the flight control computer in the ground state. The high demand trim relief logic is configured to automatically modify the neutral position of a rotor when a command input to the flight control computer to control the rotor is near an allowable limit.
Claims17
A flight control system, comprising:
- a flight control computer operable in a flight state and a ground state;
- and
- a high demand trim relief logic operable by the flight control computer when in the ground state, the high demand trim relief logic being configured to automatically modify a neutral position of a rotor when a command input to the flight control computer to control the rotor is near an allowable limit.
A method of flight, comprising:
- detecting that a command input to a flight control computer is near an allowable limit;
- and
- modifying a neutral position of a rotor via a high demand trim relief logic when flight control computer is in a “ground” state.
A method of flying an aircraft, comprising:
- operating a flight control system of the aircraft in a ground state when the aircraft is in flight;
- providing a command input to a flight control computer;
- detecting that a command input to a flight control computer is near an allowable limit;
- and
- modifying a neutral position of a rotor via a high demand trim relief logic.
