Abstract
A control unit for controlling movement of a stabilizer and an elevator on an aircraft, the control unit comprising a processor which is configured to receive a pitch reference command from a flight control input device of the aircraft, determine, based on the pitch reference command, an elevator command configured to command the elevator in the aircraft nose-up or nose-down direction, determine a difference between the elevator command and a desired elevator value corresponding to the pitch reference command, determine a threshold value as a desired maximum elevator deflection at a given pitch reference command, compare the difference with the threshold value and in response thereto generate a command signal configured to retain a current position of the stabilizer when the difference is smaller than or equal to the threshold value, and to command the elevator in the aircraft nose-up or nose-down direction based on the pitch reference command.
