A method is provided for increasing the number of takeoff and landing slots and increasing gate capacity at airports with slot controls, including airports that are constrained from operation by curfews that limit the hours when aircraft can operate. The present method is intended to be used in connection with an aircraft that is equipped with onboard wheel drive means capable of translating torque through aircraft wheels and controllable to move the aircraft independently on the ground quietly and efficiently to a runway for takeoff without reliance on the aircraft's engines or the use of external tow vehicles.
