1. A method to modify flight control laws associated with a flight control computer with a portable computer during flight, comprising:

  • certifying the flight control computer to be qualified;

    receiving a range of control law limits in an authority limiter;

    creating a qualified actuator command with a qualified control law with the flight control computer;

    creating an unqualified actuator command with an unqualified control law with the portable computer;

    creating a delta actuator command as the mathematical difference between the qualified actuator command and the unqualified actuator command;

    limiting the delta actuator command with the authority limiter based upon the range of control law limits;

    creating a final actuator command as the mathematical sum of the delta actuator command and the qualified actuator command;

    commanding a commanded actuator with the final actuator command;

    sensing movement of the commanded actuator with a first displacement sensor;

    sensing movement of a pilot controlled actuator with a second displacement sensor; and

    relaying the movement of the pilot controlled actuator to the portable computer.
