Abstract

An aircraft load management system determines a cargo through a wireless communication system to rapidly position the cargo. RFID emitter tags on each piece of cargo are triangulated relative to an aircraft internal cargo bay. Real time cargo position information is displayed to facilitate direction of drivers, loadmasters and aircrew. Cargo data is also relayed to onboard systems for mission planning, and for communication to a global information network to prioritize cargo delivery and dynamic mission re-planning. Even prior to onloading, cargo data is wirelessly communicated to the load management system to automatically plan the cargo load sequence. The load management system also autonomously loads remote controlled ground vehicles and equipment through communication therewith.

Claims

1. A system to manage a load relative an internal cargo bay, comprising:

a wireless communication system adjacent an internal cargo bay, said wireless communication system comprises a sensor system adjacent the internal cargo bay to wirelessly communicate with a cargo external to the internal cargo bay and within the internal cargo bay; and

a load management system in communication with said wireless communication system to determine a cargo position relative the internal cargo bay.

5. The system as recited in claim 1, wherein said sensor system comprises a multiple of sensors operable to determine a three dimensional cargo position.

6. The system as recited in claim 1, wherein said wireless communication system is in communication with said sensor system to determine a three dimensional cargo position of the cargo within said internal cargo bay and external to said internal cargo bay.

7. The system as recited in claim 1, wherein said load management system is operable to determine a cargo position within the aircraft internal cargo while the cargo is external to the internal cargo bay, the cargo position determined to maintain an aircraft C.G. within a predefined limit.

8. The system as recited in claim 1, further comprising a display in communication with said load management system, said display operable to display symbology which represents the cargo relative a Cargo Bay Floor Plan View representative of the position of the cargo relative the internal cargo bay.

9. The system as recited in claim 1, wherein said load management system is an aircraft load management system for a rotary-wing aircraft.

10. The system as recited in claim 9, wherein said wireless communication system comprises at least one sensor mounted external to said internal cargo bay.

11. The system as recited in claim 1, further comprising an active controlled floor roller system in communication with said load management system.

12. The system as recited in claim 11, further comprising an active cargo-locking system within said active controlled floor roller system.

2-4. -4. (canceled)

13-15. -15. (canceled)

16. A method of managing an aircraft load for an aircraft with an internal cargo bay comprising:

(A) wirelessly communicating with a set of emitters attached to a cargo external to said internal cargo bay and within said internal cargo bay;

(B) calculating a three-dimensional position of the cargo within the internal cargo bay and external to the internal cargo bay with a load management system; and

(C) displaying symbology representing the cargo relative a Cargo Bay Floor Plan View of the aircraft in response to said step (B).

17. The method as recited in claim 16, further comprising:

(D) determining an aircraft cargo arrangement to maintain an aircraft C.G. within a predefined limit.

18. The method as recited in claim 17, wherein said step (D) further comprising the steps of:

(a) determining a position within the aircraft internal cargo bay for the cargo while the aircraft cargo is external to the internal cargo bay.

19. The method as recited in claim 18, wherein said step (a) further comprising:

(i) moving the cargo along an active controlled floor roller system in communication with the aircraft load management system; and

(ii) locking the cargo with an active cargo-locking system at the position after said step (i).

20. The method as recited in claim 18, wherein said step (a) further comprising:

(i) wireless detecting a set of emitters attached to each of a multiple of cargo pieces; and

(ii) determining a position within the aircraft for each of the multiple of cargo pieces prior to the cargo being loaded within the aircraft internal cargo bay

21. The method as recited in claim 16, further comprising:

(D) wirelessly communicating with a remote control vehicle; and

(E) controlling movement of the remote control vehicle relative the aircraft internal cargo bay in response to said step (D) through the load management system.

22. The method as recited in claim 16, wherein said step (D) further comprising:

(a) triangulating the three dimensional cargo position of the cargo relative the aircraft internal cargo bay.

23. The method as recited in claim 16, wherein said step (D) further comprising:

(a) triangulating the three dimensional cargo position of the cargo within the aircraft internal cargo bay.

24. The method as recited in claim 16, further comprising:

(D) communicating cargo data from the set of emitters attached to the cargo to the load management system.
