11. A control unit comprising:
-
an input to couple directly to pilot control device input; an output to couple directly to an actuator to control a flight control surface; and a processor coupled to the input and to the output to directly control the flight control surface via the actuator, while complying with predetermined control laws and safety monitoring independently performed by the processor, as a direct function of pilot control device input. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
