ABSTRACT:
A constant force mechanical spring and a varying force hydraulic actuator combine to provide feel to a pilot of his movement of an airplane's elevators. A constant force bias spring works against the hydraulic actuator to reduce the actuators effectiveness to nearly zero at minimum feel force conditions.
