Abstract

A method for displaying vehicle arrival management information is provided by display (200). Display (200) includes an arrival slot display area (222) which is bounded by a relative time scale (214) defining a Y axis and an actual time scale (216) defining an X axis. A multiplicity of symbols (226) representing arrival slots extends from the origin of the display. When used in an aircraft arrival management application, symbols (228) represent aircraft in flight, and symbols (230) represent aircraft still on the ground and whose flight plan is proposed. Those symbols (228, 230) are located on the display at the appropriate estimated arrival time, assigned slot time coordinates corresponding with a respective arrival time slot represented by a respective arrival slot symbol (226). To further aid in controlling the arrival traffic, each of the in-flight aircraft symbols (228) for aircraft associated with the user includes an ETA envelope (244) associated with the in-flight aircraft symbol (228), the symbol (228) being located at coordinates which represent the estimated ETA and slot assignment of the aircraft. Aircraft which have been assigned to an arrival slot, but which have not yet taken off, are indicated by a symbol (230) which is located at coordinates representing the estimated ETA and slot assignment for that flight.

Claims

1. A method for displaying aircraft arrival management information for a particular airport from data supplied from an air traffic management system, including both airport status information and aircraft flight data, said method comprising the steps of:

providing means for processing and displaying the data supplied from an air traffic management system;

establishing a multiplicity of arrival time slots for the airport responsive to the airport status information;

assigning a plurality of flights identified by the aircraft flight data to appropriate ones of said multiplicity of arrival time slots;

forming a two dimensional graphic representation of said multiplicity of arrival time slots, said two dimensional graphic representation having an estimated arrival time coordinate and an assigned slot time coordinate and a multiplicity of first symbols

positioned thereon to respectively represent said multiplicity of arrival time slots;

extracting an estimated time of arrival envelope from the aircraft flight data for at least one of said plurality of assigned flights; and

,

displaying said estimated time of arrival envelope on said two dimensional graphic representation for said at least one assigned flight.

2. The method as recited in claim 1 where said step of forming a two dimensional graphic representation of said multiplicity of arrival time slots includes the step of forming a first axis as said estimated arrival time coordinate and a second orthogonal axis as said assigned slot time coordinate.

3. The method as recited in claim 2 where said step of displaying said estimated time of arrival envelope includes the step of displaying a line having one endpoint defined by a flight'"'"'s latest potential estimated time-of-day of arrival and an opposing endpoint defined by the flight'"'"'s earliest estimated time-of-day of arrival.

4. The method as recited in claim 3 where said estimated time of arrival envelope includes the step of displaying a second symbol positioned on said line to designate a time-of-day representing the flights expected time-of-day of arrival.

5. The method as recited in claim 1 where said step of forming a two dimensional graphic representation of said multiplicity of arrival time slots includes the step of designating a first relative time span for a portion of said assigned flights having a relative time of arrival less than a first predetermined value by displaying said first relative time span with a background color band different from a background color of a second relative time span.

6. The method as recited in claim 5 where said step of forming a two dimensional graphic representation of said multiplicity of arrival time slots includes the step of designating a third relative time span for a portion of said assigned flights having a relative time of arrival greater than a second predetermined value by displaying said third relative time span with a background color band different from a background color of said second relative time span.

7. The method as recited in claim 1 where said step of forming a two dimensional graphic representation of said multiplicity of arrival time slots includes the step of positioning said multiplicity of first symbols along an angular path with respect to said estimated arrival time coordinate and said assigned slot time coordinate.

8. The method as recited in claim 7 where said step of forming a two dimensional graphic representation of said multiplicity of arrival time slots includes the step of spacing said first symbols responsive to an acceptance rate of the particular airport at a corresponding time-of-day.

9. The method as recited in claim 1 where said step of forming a two dimensional graphic representation of said multiplicity of arrival time slots includes the step of zooming in to increase the spacing between increments of said estimated arrival time coordinate and said assigned slot time coordinate responsive to a command input by a user.

10. The method as recited in claim 1 where said step of forming a two dimensional graphic representation of said multiplicity of arrival time slots includes the step of indicating any of the multiplicity of arrival time slots that are closed.

11. The method as recited in claim 4 further comprising the step of assigning a preferred arrival time to a particular one of said assigned flights by using a coordinate input device to drag said second symbol for said assigned flight to new coordinates representing a desired arrival time slot and displaying a third symbol overlaying a respective one of said first symbols.

12. The method as recited in claim 11 where said step of assigning a preferred arrival time includes the step of displaying lead lines extending between said first symbol of said desired arrival time slot and a respective time scale on each of said first and second axes.

13. A method for displaying vehicle arrival management information for a particular terminal having a multiplicity of arrival time slots to which at least a portion thereof are assigned to particular vehicles, said method comprising the steps of:

providing a display device and a processor in communication with a vehicle traffic management system;

forming a two dimensional graphic representation of the multiplicity of arrival time slots, said two dimensional graphic representation having an estimated arrival time coordinate and an assigned slot time coordinate and a multiplicity of first symbols positioned thereon to respectively represent the multiplicity of arrival time slots;

identifying which of the multiplicity of arrival time slots have a vehicle assigned thereto and displaying identification indicia therefor adjacent to a respective first symbol;

obtaining vehicle data including a latest estimated time-of-day of arrival, an expected estimated time-of-day of arrival, and an earliest estimated time-of-day of arrival for at least a portion of the assigned vehicles from the vehicle traffic management system; and

,

displaying a representation of an estimated time-of-day of arrival envelope for said portion of the assigned vehicles, said estimated time of arrival envelope representation including an indication of the latest estimated time-of-day of arrival, the expected estimated time-of-day of arrival, and the earliest estimated time-of-day of arrival.

14. The method as recited in claim 13 where said step of forming a two dimensional graphic representation of the multiplicity of arrival time slots includes the steps of providing a first axis defined by said estimated arrival time coordinate and providing a second orthogonal axis defined by said arrival slot coordinate.

15. The method as recited in claim 13 further comprising the step of inputting a preferred arrival time for at least one vehicle and displaying a symbol representing said at least one vehicle in overlaying relationship with respect to a symbol representing a desired one of said arrival time slots corresponding to said preferred arrival time.

16. The method as recited in claim 13 where said step of displaying a representation of an estimated time-of-day of arrival envelope includes the step of displaying a line positioned at a relative time defined by a respective assigned time slot, said line extending from an endpoint designated by the earliest estimated time-of-day of arrival to an endpoint designated by the latest potential estimated time-of-day of arrival.

17. The method as recited in claim 13 where said step of identifying includes the step identifying proposed flights input by a user and selective display thereof.

18. The method as recited in claim 15 where the step of inputting a preferred arrival time includes the step of assigning a preferred arrival time to said at least one vehicle by using a coordinate input device to drag said symbol for said at least one vehicle to new coordinates representing a desired arrival time slot and displaying another symbol overlaying said symbol representing said desired arrival time slot.

19. A method of temporally displaying arrival management information for a particular terminal having a multiplicity of arrival time slots to which at least a portion thereof are assigned to particular vehicles, said method comprising the steps of:
