Abstract: A shift mechanism for an aircraft control system for reversibly shifting the control system of the aircraft between a power mode and a manual mode of operation. The shift mechanism has a stick control input connection, a primary control surface output connection and a secondary control surface output connection. The input connection is made to a bell crank-shaped housing which is pivoted to the aircraft structure and the output connections are connected to an idler arm and connecting member, respectively, that are pivoted to the housing. The connecting member is moved by an actuator between a first position wherein its pivotal connection to the secondary control surface output connection is aligned with the pivotal connection of the housing to the aircraft and a second position of non-alignment. During this second position, the primary control surface output connection is disconnected from the idler arm.

Abstract: A high visibility man-overboard rescue beacon is provided having a strobe light that is automatically energized in a flashing mode by the act of removing the beacon from its holder on board boat. Upon removal from the holder, a set of self-erecting radar reflective coated flags are also automatically deployed.

Abstract: A control system including a jam isolating coupling for use in an aircraft including a plurality of related movable control members adapted to be moved in unison under normal operation conditions by appropriate separate and interconnected actuators. The related movable members are each provided with separate actuating shafts joined by a coupling which includes a sleeve which connects both shafts. Shearable rivets pass through suitable apertures in the sleeve and in one of the actuating shafts while the related actuating shaft is securely fastened to the sleeve by a plurality of bolts. The coupling structure is capable of accommodating any loads associated with the normal operation of the control system.
