Method for Monitoring Autonomous Accelerated Aircraft Pushback

Abstract

A method for monitoring an autonomous accelerated pushback process in an aircraft equipped with an engines-off taxi system is provided to maximize safety and facilitate the accelerated pushback process. The aircraft is equipped with a monitoring system including a number of different kinds of sensors and monitoring devices positioned to maximally monitor the aircraft's exterior ground environment and communicate the presence or absence of obstructions in the aircraft's path while the pilot is controlling the engines-off taxi system to drive the aircraft in reverse away from a terminal gate and then turn in place at a selected location before driving forward to a taxiway. The sensors and monitoring devices may be a combination of cameras, ultrasound, global positioning, radar, and LiDAR or LADAR devices, and proximity sensors located at varying heights adapted to continuously or intermittently scan or sweep the aircraft exterior and ground environment during aircraft ground movement.

PRIORITY CLAIM [0001]This application claims priority from United States Provisional Patent Application No. 61 / 866,044, filed 15 Aug. 2013, the disclosure of which is fully incorporated herein by reference.TECHNICAL FIELD [0002]The present invention relates generally to monitoring the pushback of aircraft from a terminal gate or stand and specifically to a method for monitoring autonomous pushback in an aircraft equipped with an engines-off taxi system controllable for autonomous aircraft ground travel.BACKGROUND OF THE INVENTION[0003]Terminal gate and ramp areas in today's airports can be very congested places, with simultaneously arriving and departing aircraft and ground service vehicles and ground personnel servicing and directing aircraft into and out of gates. The avoidance of collision incidents in this area requires careful monitoring and control of the locations and movement of aircraft and other vehicles as they maneuver within these areas. The pushback of departing aircra...

AI Technical Summary

Benefits of technology

This patent is about a method for safely maneuvering an aircraft equipped with an engines-off taxi system in reverse during a pushback process and turning it to a take-off runway. The method involves monitoring the environment around the aircraft to identify potential obstructions and communicating this information to the pilot in real-time. By controlling the engines-off taxi system, the pilot can drive the aircraft safely in reverse, turn it through an angle to optimize ground movement, and then drive forward to a takeoff runway. This method minimizes the assistance needed from ground personnel and also includes the use of a ground leading line or indicators to guide the aircraft along a safe path. The technical effect of this patent is to provide a safer and more efficient method for accelerated pushback and autonomous ground movement in aircraft equipped with an engines-off taxi system.

Problems solved by technology

The pushback of departing aircraft must be guided with even more care because the aircraft is moving in reverse, and the pilot and flight crew are not able to see the entire environment surrounding the aircraft.

Aircraft pushback, as it presently conducted, is a time and labor-intensive process that all too frequently produces delays in an airline's flight schedule.

The efficiency and speed of aircraft pushback operations tends to 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.

None of the foregoing art, however, suggests a method for monitoring a streamlined, accelerated pushback process or autonomous reverse ground travel in an aircraft equipped with an engines-off taxi system, wherein the aircraft is driven safely in reverse along an optimum path and turned at an angle that expedites pushback, so that it may then be driven forward for takeoff.
