Abstract
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.
