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.
Claims10
A command bar device for providing pitch and roll information, said device comprising:
- a frame;
- a magnet assembly including a permanent magnet;
- means mounting said magnet assembly to said frame for pivotal movement about a pair of mutually perpendicular axes corresponding to pitch and roll axes;
- a command bar coupled with said magnet assembly for movement therewith about said axes;
- a pair of coils supported on said frame in proximity to said magnet, said coils being operable to receive current to produce fields for selectively deflecting said magnet in a manner to pivot said magnet assembly about each of said axes, thereby displacing said command bar with respect to said axes in movement corresponding to pitch and roll movement;
- and
- means providing an indication of the direction and extent to which said command bar is displaced with respect to said axes.
