Abstract

A method for enhancing pilot and cockpit crew efficiency and increasing aircraft safety during aircraft ground travel between landing and takeoff is provided. The present method is most effective in enhancing pilot efficiency and aircraft safety in an aircraft equipped with at least one powered, self-propelled drive wheel that drives the aircraft on the ground independently of the aircraft main engines or external tow vehicles that is controlled by the pilot and cockpit crew to maneuver the aircraft during ground travel.

Claims (12)

1. A method for improving safety and efficiency of aircraft cockpit operations and pushback in an aircraft equipped with at least one powered self-propelled drive wheel controllable to drive the aircraft on the ground without operation of aircraft main engines or attachment to a tow vehicle, comprising:

a. equipping the aircraft with the at least one electric powered self-propelled drive wheel controllable from the aircraft's cockpit by the aircraft's pilot or cockpit crew to control ground travel of the aircraft without operation of aircraft main engines or attachment to a tow vehicle;

b. while the aircraft is parked at a gate, determining a time during the aircraft's travel to a takeoff taxiway when selected aircraft departure and pushback procedures or checklists can be performed to enhance efficiency and safety of aircraft ground travel and cockpit operations;

c. completing appropriate selected procedures or checklists while the aircraft is parked at the gate using ground power or an auxiliary power unit;

d. after the aircraft is approved for pushback, activating the at least one electric powered self-propelled drive wheel and controlling movement of the aircraft in reverse away from the gate while the pilot and crew maintain heads up and focus on the aircraft external environment during aircraft movement to a selected safe location away from the gate, and performing additional appropriate selected procedures or checklists while the aircraft is stopped at the selected safe location; and

e. controlling movement of the aircraft in a forward direction and, if any additional appropriate procedures or checklists have not been performed, performing the additional appropriate procedures or checklists at a safe time or location, comprising when the aircraft is stopped near a runway or in a runway queue, wherein when all appropriate procedures or checklists have been performed, the pilot controls the at least one electric powered self-propelled drive wheel to move the aircraft forward to a takeoff taxiway location where aircraft main engines are safely started and the aircraft takes off.

2. The method described in claim 1 , further comprising

a. equipping the aircraft with electric powered self-propelled drive wheel assemblies mounted in nose wheels activatable and controllable from the aircraft's cockpit by the pilot or cockpit crew; and

b. when the aircraft has taken off and then landed, at a selected taxi speed eliminating operation of aircraft engines and activating and controlling the electric powered self-propelled drive wheel assemblies to drive the aircraft safely in a forward direction to a parking location with pilot and crew heads up while maintaining improved pilot situational awareness of and focus on the aircraft external environment while driving the aircraft on the ground and performing arrival checklist tasks at a location that enhances safety of cockpit operations.

3. The method described in claim 1 , further comprising completing any selected aircraft departure and pushback procedures or checklists not completed at the gate when the aircraft is stopped at the selected safe location.

4. The method described in claim 1 , further comprising completing any selected aircraft departure and pushback procedures or checklists not completed at the selected safe location when the aircraft is stopped near a runway.

5. The method described in claim 1 , further comprising completing any selected aircraft departure and pushback procedures or checklists not completed at the selected safe location when the aircraft is stopped in a runway queue.
