Abstract
A device is disclosed by which two paired controls in an aircraft flight control system, such as pitch controls, or the roll controls, which are ordinarily operated in coordination by the pilot by use of a single operating control may, when the control on one side of the airplane is damaged and jammed, accomplish a disconnect of that side, and so free the opposite side control for operation. The aircraft can often be flown with just the one side control in commission, if freed from the opposite side. The device is in the nature of a bell crank, and the disconnect means is in the hub thereof. Also disclosed is a novel bi-directional sensor incorporated in the input arm of the bell crank, and which gives an indication to the pilot when the linkage to the corresponding control surface, or the control surface, is damaged and jammed. This sensor has application other than in aircraft control systems.
