DEFINITION

Classification: 244/76

(under subclass 75) Devices and systems for automatically

controlling aircraft along a predetermined course or in response to changing conditions. This includes aircraft arranged to automatically maintain stable equilibrium.

(1) Note. For similar subject matter for controlling missiles continue the search in this class, subclasses 3.1+.

(2) Note. These are the generic subclasses for the steering of dirigible craft automatically in two or three dimensions. See subclass 175 for a statement as to the line between the various vehicle and motor classes and for the classes which provide for electrically controlled or actuated steering for mobile craft.

SEE OR SEARCH CLASS

73, Measuring and Testing,

178+, for navigating instruments in general where no control of the craft is involved. 91, Motors: Expansible Chamber Type, appropriate subclasses for fluid servo-motors and controls therefor.

102, Ammunition and Explosives,

384, for drop bombs having automatic means for controlling the course of their flight.

114, Ships,

21.1, and 23+ for torpedoes with automatically actuated steering mechanism; see subclass 24 where the control mechanism includes a gyroscope, and subclasses 144+ for miscellaneous devices, including the automatically actuated devices for changing the direction or speed of a ship.

180, Motor Vehicles,

167+, and 170+ as explained in the reference to that class (180) appearing in subclass 75 above.

364, Electrical Computers and Data Processing Systems,

130+, for generic data processing control systems.

395, Information Processing System Organization,

500.29, for the mathematical simulation of a vehicle.

701, Data Processing: Vehicles, Navigation, and Relative Location, 3+, for computing systems for vehicle control or vehicle condition indication and subclasses 200+ for computations in the application of navigation.
