Claim:
1. A system for simultaneously controlling autonomous ground movement and direction of ground travel of an aircraft with landing gear wheels equipped with non-engine drive means, comprising: a. one or more pairs of main landing gears connected to an aircraft at selected locations on opposite sides of a central axis of an aircraft, each said one or more pairs of main landing gears comprising at least one bogie unit with a plurality of paired main wheels connected by a truck beam, wherein one or more of said main wheels on said at least one bogie unit comprise drive wheels equipped with a non-engine drive means comprising an electric motor controllable to drive said one or more main wheels to move said aircraft autonomously during taxi on a ground surface; b. a nose landing gear comprising at least a pair of nose wheels and a nose wheel steering system controllable to move said aircraft in a required ground travel direction; c. a nose landing gear steering angle detection and measurement means for determining data from a turning angle of said nose landing gear comprising at least a steering angle sensor; and d. a processor in electronic communication with said nose landing gear steering angle detection and measurement means adapted to receive and process said turning angle data, wherein said processor is in communication with said non-engine drive means to simultaneously control aircraft autonomous ground travel and ground travel direction in response to said turning angle data.
