Ground incursion avoidance system and display
First Claim
1. A flight deck display system for an aircraft, comprising:
- a processor adapted to receive identification data from an aircraft identification database, the identification data representative of an aircraft during a ground maneuver, the processor operable, in response thereto, to determine a zone of protection about the aircraft and supply one or more image rendering display commands; and
a display device coupled to receive the image rendering display commands and operable, in response thereto, to render an image of an envelope encompassing the aircraft that is representative of the zone of protection.

Abstract
An airborne processor is linked to a ground-based, vehicle based, or satellite-based supplier of approaching aircraft data and/or terrain data, including airfield structures. The processor also has access to the aircraft'"'"'s state, e.g. position, speed, intended route, aircraft dimensional data, or the like. Algorithms within the processor calculate a zone of protection about the aircraft in light of aircraft type, turning radius, and other identifying data. The processor combines the present and estimated future positions of the aircraft with the approaching aircraft and/or airfield structure data, and creates an alert to the crew if a threat of a ground incursion is detected. The display provides a visual of the zone of protection about the aircraft, and approaching aircraft and/or airfield structure to draw the attention of the crew to the threat.

8. A flight deck display system for an aircraft, comprising:
-
a processor adapted to receive identification data from an aircraft identification database, the identification data representative of a first structure during a ground maneuver and at least a second structure, the processor operable, in response to the identification data, to determine a first zone of protection associated with the first structure and a second zone of protection associated with the second structure and supply one or more image rendering display commands; and a display device coupled to receive the image rendering display commands and operable, in response thereto, to render an image of an envelope encompassing each of the first structure and the second structure and representative of the first and second zones of protection. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A method of displaying a zone of protection during a ground maneuver on an aircraft flight deck display system, the method comprising the steps of:
-
obtaining real-time vehicle ownship identification data during a ground maneuver from an aircraft identification database and at least one of real-time additional vehicle identification data and airfield structure data; determining a zone of protection associated with the vehicle ownship, and a zone of protection associated with at least one of the additional vehicle and the airfield structure based at least in part on the processed data; calculating whether at a present position, heading, and speed, the zone of protection associated with the vehicle ownship will encroach upon the zone of protection associated with at least one of the additional vehicle and the airfield structure; and displaying an image of an envelope encompassing each of the vehicle ownship, the additional vehicle and the airfield structure and representative of the determined zones of protection on the aircraft flight deck display system. - View Dependent Claims (17, 18, 19)
