Abstract
The invention relates to a control column (2) for a copilot of an aircraft, coupled for control of roll and pitch by a linkage (5) to the pilot's control column (1). This linkage comprises two parallel rods (6,7) pivoted on the one hand to the column (1) and on the other hand to a member (13) connected to the column (2) by a double universal joint (14, 17). When operative, the column (2) is locked to the member (13) by a lock bolt (19). This control column can be put out of action by releasing the said bolt and can be secured by hooking to a fixed point, in which case the double universal joint (14, 17) ensures its disconnection from the column (1) and thus prevents any misoperation.
