Abstract

A system and method are provided that direct a real time global view with images of an aircraft's entire exterior environment from an external monitoring system located on an aircraft equipped with landing gear wheel-mounted electric taxi drive systems powering ground travel to an integrated head-up display worn by a pilot driving the aircraft with the electric taxi drive systems within an airport ramp area. The real time global view and images produced by the monitoring system are communicated to the integrated head-up display in the form of an actual picture of the ramp area environment exterior to the aircraft viewable by the pilot with the head-up display in real time as the pilot maneuvers the aircraft within the ramp area with the electric taxi systems. The pilot can change the images viewed in the head-up display by changing head position.

First claim

The invention claimed is:

1. An airport ramp area ground movement system for electric taxi drive system-equipped aircraft that integrates a pilot wearable head-up display system with an external aircraft monitoring system to enable pilots of the equipped aircraft to remain head up while safely maneuvering the aircraft with the electric taxi drive systems within the airport ramp area, comprising:
a. a ramp area in an airside area of an airport structured to accommodate multiple arriving and departing aircraft, passenger loading bridges, ground service vehicles, and ground service personnel;
b. aircraft equipped for pilot-controlled ground travel with landing gear wheel-mounted electric taxi drive systems driven within the ramp area by pilots controlling the electric taxi drive systems;
c. one or more programmable pilot head-up display systems responsive to pilot head movements, each said pilot head-up display system comprising at least a wearable head-mounted element supporting a display element viewable by pilots wearing said head-up display systems located in cockpits of said equipped aircraft and responsive to changes in pilot head position and being programmable to receive identical or different displays of said actual real time three-dimensional panoramic images of said volume of ramp space directly from said integrated monitoring system and indirectly from said processing system;
d. an equipped aircraft external monitoring system integrated with said one or more pilot head-up display systems comprising single or multiple scanning monitoring devices positioned in exterior surface locations on said equipped aircraft and operable to produce and transmit actual real time three-dimensional panoramic images of at least a volume of ramp space adjacent to said equipped aircraft extending from said ramp ground surface to just above wings of said equipped aircraft not visible to said pilots in said cockpits directly or indirectly to said programmable pilot head-up display systems, further comprising the single or multiple scanning monitoring devices positioned in equipped aircraft exterior surface locations to provide a view from a nose to a tailskid of the aircraft; and
e. a processing system in communication with said one or more programmable pilot head-up display systems and with said integrated monitoring system to process and transmit said actual real time three-dimensional panoramic images of said volume of ramp space communicated to said processing system by said integrated monitoring system and then to transmit the processed actual real time three-dimensional panoramic images from the processing system to the pilot head-up display systems as the at least one pilot maintains the head-up position, views the processed real time three-dimensional panoramic images received from the processing system, and maneuvers the equipped aircraft through the ramp area in response to the viewed images to avoid collisions and adverse incidents, wherein said processing system comprises a processor located onboard said equipped aircraft in communication with said integrated monitoring system and with said one or more programmable pilot head-up display systems or a processor located offboard said equipped aircraft in communication with an onboard processor and with said one or more programmable pilot head-up display systems.

2. The system of claim 1 , further comprising multiple ones of said programmable head-up display systems worn by multiple pilots in cockpits of said equipped aircraft, said display elements of said multiple programmable head-up display systems being programmed to receive a same or a different display of said actual real time three-dimensional panoramic images.

3. The system of claim 1 , wherein said integrated monitoring system is operable to produce a continuous feed of said actual real time three-dimensional panoramic images from said single or multiple scanning monitoring devices for transmission to said display elements of one or more programmable pilot head-up display systems.

4. A method that enables pilots to maintain a head-up position and to safely maneuver aircraft equipped with pilot-controllable electric taxi drive systems without adverse incidents and collisions during ground travel within an airport ramp area, comprising:
a. at an airport having a ramp area in an airside area of the airport structured to accommodate multiple arriving and departing aircraft, passenger loading bridges, ground service vehicles, and ground service personnel, providing aircraft equipped for pilot-controlled ground travel with landing gear wheel-mounted electric taxi drive systems to maneuver the equipped aircraft within the ramp area;
b. providing one or more programmable pilot head-up display systems responsive to pilot head movements, each pilot head-up display system comprising at least a wearable head-mounted element supporting a display element viewable by pilots wearing the head-up display systems located in cockpits of said equipped aircraft;
c. providing an equipped aircraft external monitoring system integrated with the one or more programmable pilot head-up display systems comprising single or multiple scanning monitoring devices positioned in exterior surface locations on the equipped aircraft and operable to produce and transmit actual real time three-dimensional panoramic images of at least a volume of ramp space adjacent to the equipped aircraft extending from the ramp ground surface to just above wings of said equipped aircraft not visible to pilots in the cockpits, providing a processing system to receive the transmitted actual real time three-dimensional panoramic images in communication with the integrated monitoring system and with the pilot head-up display systems, and programming the pilot head-up display systems to receive and display the same or different ones of the actual real time three dimensional panoramic images communicated by the processing system or by the integrated monitoring system;
d. controlling the electric taxi drive systems and maneuvering the equipped aircraft within the ramp area by at least one pilot in a head-up position wearing one of the programmable head-up display systems, transmitting the actual real time three-dimensional panoramic images of the volume of ramp space adjacent to the equipped aircraft to the programmable pilot head-up display systems directly from the integrated monitoring system or indirectly through the processing system;
e. continuing to maneuver the equipped aircraft within the ramp area with the electric taxi drive systems by the pilot maintaining the head-up position, viewing, and changing views of the actual real time three-dimensional panoramic images of the volume of ramp space adjacent to the equipped aircraft viewed in the display elements in response to the pilot changing head position; and
f. identifying potential adverse and collision incidents within the volume of ramp space in real time by the pilot from the actual real time three-dimensional panoramic images viewed in the display element, and controlling the ramp area ground travel of the equipped aircraft with the electric taxi drive systems to avoid or prevent an adverse or collision incident.

5. The method of claim 4 , wherein said processing system comprises a processor located onboard said equipped aircraft in communication with said integrated monitoring system and with said one or more programmable pilot head-up display systems or a processor located offboard said equipped aircraft in communication with an onboard processor and with said one or more programmable pilot head-up display systems.

6. The method of claim 4 , further comprising programming said one or more programmable pilot head-up display systems to receive on the display elements the same or different displays of
