Method for accelerated powered self push back of an aircraft
a self-push back and aircraft technology, applied in the direction of power plant arrangement/mounting, transportation and packaging, ground installation, etc., can solve the problems of increasing the time an aircraft spends on the ground, many aircraft departure delays, and time-consuming processes, so as to reduce the time required, reduce the turnaround time of aircraft, and minimize the total distance driven

Benefits of technology
This method significantly reduces aircraft turnaround time by 3-5 minutes, minimizes reliance on ground personnel, and eliminates the risks associated with reverse thrust, enabling safe and efficient movement of aircraft through congested airport areas.
Problems solved by technology
Many aircraft departure delays are the direct result of tug unavailability.
This process is time-consuming and may significantly increase the time an aircraft spends on the ground.
This process, known as reverse thrust, is problematic when used by jet engines and can be dangerous.
The potential for injury to ground personnel, ground vehicles, and airport structures from FOD and also from jet blast from an operating engine can be significant.
Dependence on the use of a departing aircraft's main engines is neither a safe nor an efficient push back procedure.
The efficiency and speed of aircraft push back operations may be adversely affected by the ground congestion found in most large airports.
This strains not only the available towing equipment, but also the available ground personnel.
Neither the airline nor the flight crew currently has any control over this situation.

Embodiment Construction
[0021]Maximizing the efficiency of aircraft turnaround to reduce the time an aircraft spends on the ground continues to receive attention from airlines and airports in an effort to increase revenues in an era of ever-increasing operating costs. While specific estimates vary, it is generally agreed that even a minute saved during aircraft turnaround may produce substantial annual cost savings. Consequently, modifications to gate structures and turnaround procedures that achieve turnaround reductions are of great interest to airport and airline operators.
[0022]In the most commonly used aircraft turnaround process, an aircraft is towed or powered by thrust from its main engine into a gate or other parking location to park in a nose-in or perpendicular orientation with respect to the gate or terminal. One or more, most commonly only one, passenger loading bridges are connected with aircraft doors, arriving passengers and baggage exit the aircraft, the aircraft is serviced, departing pas...

A method for accelerated power push back of an aircraft equipped with a pilot-controlled engines-off taxi system that drives the aircraft without reliance on the aircraft's main engines or tugs is provided. An aircraft is quickly and efficiently moved out of a gate where it is positioned in a nose-in orientation. The pilot controls the taxi system to drive the aircraft in reverse along a perpendicular path away from the terminal to a location where there is sufficient space for the aircraft to stop and turn, and the aircraft is turned and driven in a forward direction to a takeoff runway. Pilot reliance on ground personnel guidance during push back maneuvers is minimized by providing a monitoring system designed to monitor gate and ramp areas around the aircraft in any visibility or environmental conditions and provide feedback to the pilot.
Description
PRIORITY CLAIM[0001]This application claims priority from U.S. Provisional Patent Application No. 61 / 857,213, filed 22 Jul. 2013, the disclosure of which is fully incorporated herein by reference.TECHNICAL FIELD[0002]The present invention relates generally to a method for moving a parked aircraft on the ground without operation of the aircraft's main engines or tow vehicles and specifically to a method for powered self push back of an aircraft that quickly and autonomously moves an aircraft in reverse and turns the aircraft for travel to a takeoff runway.BACKGROUND OF THE INVENTION[0003]Most airports, especially large airports, currently simultaneously handle large numbers of arriving and departing aircraft of different sizes and body types. The successful management of a large volume of aircraft ground traffic requires careful control of all aircraft ground movement, particularly the movement of departing aircraft. Aircraft parked at a gate or parking area in an airport prior to de...
