An auxiliary drive wheel taxi system for driving an aircraft autonomously without reliance on engine operation during ground travel is designed for installation in an aircraft location other than on nose or main landing gear components. The auxiliary drive wheel taxi system may be mounted in an integral housing located internally or externally on an aircraft's body at a selected location relative to main or nose landing gears and includes one or more auxiliary drive wheels mounted on an extensible strut adapted to extend from and retract into the housing. An electric, hydraulic, or pneumatic non-engine drive means controllable to provide torque required to rotate the drive wheel and drive the aircraft at desired taxi speeds may be mounted in a selected location to drive the auxiliary drive wheel. The manually or automatically controllable auxiliary taxi system is operable only to drive the aircraft during taxi.
