A command bar gives pitch and roll commands to an aircraft pilot. The command bar is carried on a magnet assembly which is supported to pivot on a pair of perpendicular edges that correspond to the pitch and roll axes. A permanent bar magnet included in the assembly has its opposite ends received within bobbins on which coils are wound. The coils are arranged in a plurality of separate tiers located above and below the ends of the magnet. Fields are generated by the coils to selectively deflect the magnet in a manner to effect pitch and roll movement of the command bar.

A caging mechanism for caging the inner gimbal of a directional gyroscope to a horizontal position. Depression of an actuator rod turns a caging disc which is simultaneously moved linearly toward the inner gimbal by an angled ramp surface. A pair of pins pushed by the disc have enlarged heads that act against cams on the inner gimbal to provide the caging action. The actuator rod is equipped with an override spring that cushions the caging force and permits additional depression of the rod for caging of the outer gimbal.
