Abstract

Flight information display apparatus and methods compute and display maneuver space (MS) target or ownship aircraft and conflict regions (CR) with surrounding obstacles such as traffic, weather, and terrain. The display utilizes coordinates based upon heading and altitude, and optionally also upon ground speed. Capability for selecting non-conflicting maneuvers and executing the maneuvers may be built in.

Claims

1. A method, comprising:

providing a multidimensional representation of a conceptual space that defines a range of unique maneuvers for an aircraft in flight, the conceptual space including a first dimension represented by a first coordinate range of different heading values for the aircraft and a second dimension represented by a second coordinate range of different altitude values for the aircraft, each different combination of one of the heading values and one of the altitude values representing a different one of the unique maneuvers of the aircraft and corresponding to a unique region of the conceptual space;

determining a subset of the maneuvers predicted to place the aircraft in conflict with one or more objects; and

displaying the conceptual space with a visual distinction made between one or more conflict regions and a conflict avoidance region, the one or more conflict regions being representative of the subset of the maneuvers predicted to place the aircraft in conflict with the one or more objects and the conflict avoidance region being representative of at least one other of the maneuvers predicted to avoid conflict with the object.

2. The method of claim 1, which includes:

determining a margin relative to the one or more conflict regions to enhance maneuver efficiency; and

selecting a subset of the one or more other of the maneuvers predicted to avoid conflict with the one or more objects and that are within the margin.

3. The method of claim 1, wherein the conceptual space includes a third dimension representing a third coordinate range of different speed values of the aircraft, and each different combination of the one of the heading values, the one of the altitude values, and one of the speed values represents the different one of the maneuvers.

4. The method of claim 1, which includes selecting one of the other of the maneuvers corresponding to the conflict avoidance region and executing the one of the other of the maneuvers.

5. The method of claim 1, wherein the one or more objects are each another aircraft, terrain, weather, or special-use airspace.

6. The method of claim 1, wherein said determining includes:

establishing a lookahead time; and

calculating present and predicted future position of the aircraft and the one or more objects relative to the representation based on the lookahead time.

7. A computing and displaying apparatus, comprising:

means for defining a multidimensional conceptual representation of a number of maneuvers for an aircraft in flight, the representation including a first dimension representing a directional range of different heading values for the aircraft and a second dimension representing an altitude range of different altitude values for the aircraft, each different combination of one of the heading values and one of the altitude values representing a unique one of the maneuvers;

means for determining a subset of the maneuvers predicted to place the aircraft in conflict with one or more objects based on the representation; and

means for displaying a conceptual space including a first coordinate range to represent the first dimension and a second coordinate range to represent the second dimension, the conceptual space visually presenting one or more conflict regions and a conflict avoidance region, the one or more conflict regions being representative of the subset of maneuvers that place the aircraft in conflict with the one or more objects and the conflict avoidance region being representative of the maneuvers that each avoid conflict with the one or more objects.

8. The apparatus of claim 7, wherein the representation of said defining means further includes a third dimension corresponding to aircraft speed.

9. A method, comprising:

with a computer, defining a multidimensional conceptual space that represents several unique maneuvers for an aircraft in flight, the conceptual space including a first coordinate range of directional values each representing a different direction for the aircraft and a second coordinate range of different altitude values each representing a different altitude for the aircraft, each different combination of one of the directional values and one of the altitude values representing a different one of the maneuvers of the aircraft and corresponding to a different region of the conceptual space;

with the computer, determining a subset of the maneuvers each predicted to place the aircraft in conflict with one or more objects; and

displaying the conceptual space with a visual distinction between one or more conflict regions and a conflict avoidance region, the one or more conflict regions being representative of the subset of the maneuvers predicted to place the aircraft in conflict with the one or more objects and the conflict avoidance region being representative of at least one other of the maneuvers predicted to avoid conflict with the one or more objects.

10. The method of claim 9, which includes maneuvering the aircraft in accordance with a selected one of the other of the maneuvers to avoid conflict the one or more objects.

11. The method of claim 9, wherein the one or more objects include a plurality of different aircraft in flight.

12. The method of claim 11, wherein the conceptual space includes a third coordinate range of different speed values of the aircraft, each different combination of the one of the directional values, the one of the altitude values, and one of the speed values represents a different one of the unique maneuvers.

13. The method of claim 12, which includes selecting one of the other of the maneuvers corresponding to the conflict avoidance region and executing the one of the other of the maneuvers.

14. The method of claim 9, wherein the directional values each correspond to a different heading of the aircraft.

15. The method of claim 14, wherein said determining includes:

establishing a lookahead time; and

calculating present and predicted future position of the aircraft and the one or more objects relative to the conceptual space based on the lookahead time.

16. The method of claim 11, which includes:

selecting a margin relative to the one or more conflict regions to enhance maneuver efficiency; and

determining a different subset of the maneuvers predicted to avoid conflict with the one or more objects that are within the margin.

17. The method of claim 9, wherein:

the conceptual space includes a third dimension representing a third coordinate range of different speed values of the aircraft, each different combination of the one of the directional values, the one of the altitude values, and one of the speed values represents the different one of the unique maneuvers;

the one or more objects are each another aircraft, terrain, weather, or special-use airspace; and

the directional values each correspond to a different heading of the aircraft.
