ABSTRACT:
A redundant steering mechanism for a craft, especially an aircraft, comprs redundant control components which become effective when the normal steering components become disabled as a result of an electrical power supply failure. The redundant control components do not affect the normal control system but are effective even if the electrical power supply of the craft should fail. The redundant control components are operated by a hydraulic or pneumatic medium acting as a signal carrier. The control signal is a multicomponent signal, one component of which is derived from the pilot's control stick and other signal components are derived from such factors as the speed, the angle of attack and so forth. These signal components are superimposed to form the mechanical emergency control signal for operating a hydraulic or pneumatic steering element.
