An apparatus for moving parked aircraft with a tractor via an aircraft lift dolly which includes a hinged gate to entrap the aircraft nose gear. The aircraft lift dolly may be removably detachably coupled to the tractor through two attachment points to an intermediate connecting towbar. The aircraft lift dolly includes a lift mechanism having a lift carriage which is selectively elevated. The lift carriage includes a fixed forward chock and a rear chock that it repositioned longitudinally with respect to the forward chock and is hingedly coupled. The chocks are positioned about the aircraft nose gear without movement of the aircraft. Elevating the lift cradle elevates the chocks and the nose gear cradled therebetween.
