Abstract

An aircraft management system and method includes a flight plan diversion prediction system including a rerouting control unit that is configured to generate one or more reroute options for an aircraft based on an analysis of a current position of the aircraft, a predicted future position of the aircraft, a current position of an in-flight hazard, and a predicted future position of the in-flight hazard.

First claim

The invention claimed is:

1. An aircraft management system, comprising:
a flight plan diversion prediction system including a rerouting control unit that is configured to generate one or more reroute options for an aircraft based on an analysis of a current position of the aircraft, a predicted future position of the aircraft, a current position of an in-flight hazard, and a predicted future position of the in-flight hazard, wherein the one or more reroute options comprise one or more flight aspects including remaining fuel and weight for the aircraft at a destination location.

2. The aircraft management system of claim 1 , wherein the flight plan diversion prediction system further comprises a monitor in communication with the rerouting control unit, wherein the rerouting control unit is configured to show the one or more reroute options on the monitor.

3. The aircraft management system of claim 2 , wherein the rerouting control unit shows a reroute information indicator for each of the one or more reroute options on the monitor.

4. The aircraft management system of claim 3 , wherein the reroute information indicator comprises predicted landing weight, predicted fuel on board (FOB), predicted fuel remaining upon arrival, and predicted estimated time of arrival (ETA).

5. The aircraft management system of claim 1 , wherein the flight plan diversion prediction system is onboard the aircraft.

6. The aircraft management system of claim 1 , further comprising a tracking system that is configured to track the current position of the aircraft.

7. The aircraft management system of claim 1 , further comprising a flight plan database that stores a current flight plan of the aircraft.

8. The aircraft management system of claim 7 , wherein the flight plan database also stores the one or more reroute options.

9. The aircraft management system of claim 1 , further comprising an in-flight hazard tracking system that is configured to track the current position of the in-flight hazard.

10. The aircraft management system of claim 9 , wherein the in-flight hazard tracking system comprises a weather tracking sub-system that tracks weather, and wherein the in-flight hazard includes a weather cell.

11. The aircraft management system of claim 9 , wherein the in-flight hazard tracking system comprises an air turbulence tracking sub-system that tracks air turbulence, and wherein the in-flight hazard includes the air turbulence.

12. The aircraft management system of claim 9 , wherein the in-flight hazard tracking system comprises a restricted airspace tracking sub-system that tracks restricted airspace, and wherein the in-flight hazard includes the restricted airspace.

13. The aircraft management system of claim 1 , wherein the rerouting control unit is configured to determine a clearpoint for the one or more reroute options, and wherein the clearpoint is a location at which the aircraft will be clear of the in-flight hazard.

14. The aircraft management system of claim 13 , wherein the rerouting control unit is configured to determine the clearpoint by comparing the predicted future position of the aircraft and the predicted future position of the in-flight hazard.

15. The aircraft management system of claim 1 , wherein the rerouting control unit is further configured to generate the one or more reroute options based on an analysis of flight plans of previous aircraft.

16. An aircraft management method, comprising:
determining a current position of an aircraft within an airspace;
determining a current position of an in-flight hazard within the airspace;
predicting, by a rerouting control unit of a flight plan diversion prediction system, a predicted future position of the aircraft;
predicting, by the rerouting control unit, a predicted future position of the in-flight hazard; and
generating one or more reroute options for the aircraft based on an analysis of the current position of the aircraft, the predicted future position of the aircraft, the current position of an in-flight hazard, and the predicted future position of the in-flight hazard, wherein the one or more reroute options comprise one or more flight aspects including remaining fuel and weight for the aircraft at a destination location.

17. The aircraft management method of claim 16 , further comprising showing the one or more reroute options on a monitor that is in communication with the rerouting control unit.

18. The aircraft management method of claim 17 wherein the showing comprises showing a reroute information indicator for each of the one or more reroute options on the monitor.

19. The aircraft management method of claim 18 wherein the reroute information indicator comprises predicted landing weight, predicted fuel on board (FOB), predicted fuel remaining upon arrival, and predicted estimated time of arrival (ETA).

20. The aircraft management method of claim 16 , further comprising tracking, by a tracking system, the current position of the aircraft.

21. The aircraft management method of claim 16 , further comprising storing a current flight plan of the aircraft within a flight plan database.

22. The aircraft management method of claim 21 , further comprising storing the one or more reroute options within the flight plan database.

23. The aircraft management method of claim 16 , wherein the determining the current position of the in-flight hazard within the airspace comprises tracking, by an in-flight hazard tracking system, the current position of the in-flight hazard.

24. The aircraft management method of claim 16 , wherein the generating comprises determining a clearpoint for the one or more reroute options, wherein the clearpoint is a location at which the aircraft will be clear of the in-flight hazard.

25. The aircraft management method of claim 24 , wherein the determining the clearpoint comprises comparing the predicted future position of the aircraft and the predicted future position of the in-flight hazard.

26. The aircraft management method of claim 16 , wherein the generating comprises analyzing flight plans of previous aircraft.

27. The aircraft management method of claim 16 , wherein the rerouting control unit determines and predicts the one or more flight path aspects based on one or more current flight path aspects of the aircraft at the current position and a length of the one or more reroute options.
