- Publication Date: January 31, 2012
- Appl. No: 11/835861
- Application Filed: August 08, 2007
- Assignees: Honeywell International Inc. (Morristown, NJ, US)
- Claim: 1. A method of operating a communication system between an aircraft and a communication center, the method comprising: using an aircraft communication addressing and reporting system (ACARS) of the aircraft to enable or disable a gatelink communication system of the aircraft based on a detection of an out, off, on, and in (OOOI) event; wherein the OOOI event is one of an out of gate, off ground, on ground, or into gate event.
- Claim: 2. The method of claim 1 , further comprising: sending an arrival message to the communication center based on the detected OOOI event, wherein the OOOI event indicates the aircraft has arrived at the communication center.
- Claim: 3. The method of claim 2 , wherein the arrival message is sent by the ACARS to an airline ground system of the communication center.
- Claim: 4. The method of claim 3 , wherein using an ACARS of the aircraft to enable or disable a gatelink further comprises: sending an enable message to the ACARS from the airline ground system based on the received arrival message; and in response to the enable message, enabling the gatelink to communicate with a gatelink network.
- Claim: 5. The method of claim 4 , wherein enabling the gatelink further comprises passing at least one of network IDs, encryption keys and authentication keys from the ACARS to the gatelink.
- Claim: 6. The method of claim 2 , further comprising: detecting an OOOI event that indicates the aircraft is leaving; and disabling the gatelink via the ACARS in response to the detected event.
- Claim: 7. The method of claim 1 , further comprising: storing an enable gatelink airport list in a memory of the ACARS, and automatically enabling the gatelink communication system at airports in the gatelink airport list.
- Claim: 8. The method of claim 1 , wherein using an ACARS of the aircraft to enable or disable a gatelink further comprises: monitoring an uplink to a communication management unit (CMU) of the ACARS for a disable gatelink signal; and upon detection of the disable gatelink signal, disabling the gatelink.
- Claim: 9. The method of claim 7 , further comprising: when at an airport not on the gatelink airport list, monitoring an uplink to the CMU of the ACARS for an enable signal; and upon detection of the enable signal, enabling the gatelink.
- Claim: 10. A method of transferring data between an aircraft and a communication center, the method comprising: monitoring out, off, on, and in (OOOI) events for an arrival signal with an aircraft communication addressing and reporting system (ACARS); upon detection of the arrival signal, notifying an associated airline ground system of the arrival with the ACARS; determining if data needs to be communicated between the aircraft and the airline ground system; when data needs to be communicated, providing a communication message to a CMU of the ACARS; determining if a gatelink communication system is to be used for at least a portion of the communication; when the gatelink communication system is to be used for at least a portion of the communication, enabling a gatelink with the ACARS; and communicating between the aircraft and the communication center with the enabled gatelink.
- Claim: 11. The method of claim 10 , further comprising: when the gatelink communication system is not to be used, communicating between the aircraft and the airline ground system via the ACARS.
- Claim: 12. The method of claim 10 , further comprising: displaying a message to a crew of the aircraft regarding data to be communicated.
- Claim: 13. The method of claim 10 , wherein enabling a gatelink with the ACARS further comprises passing at least one of network IDs, encryption keys and authentication keys from the ACARS to the gatelink.
- Claim: 14. The method of claim 10 , wherein determining if data needs to be communicated between the aircraft and the airline ground system further comprises: determining if a flight management computer (FMC) navigation database needs to be uploaded to the aircraft.
- Claim: 15. The method of claim 14 , further comprising: when the gatelink is to be used, the FMC navigation database received by the gatelink is downloaded to a FMC of the aircraft; and when the gatelink is not to be used, communicating the FMC navigation database to the ACARS and then transferring the FMC navigation database to the FMC of the aircraft.
- Claim: 16. A communication system for an aircraft, the system comprising: a gatelink communication system configured to communicate with a gatelink network when within range of the gatelink network; at least one sensor configured to sense data that verifies the proximity of the aircraft to a communication center that includes the gatelink network, wherein an out, off, on, and in (OOOI) event is determined based at least in part on the data from the at least one sensor; an ACARS configured to communicate with an airline ground system of the communication center, the ACARS further configured to enable or disable the gatelink based at least in part on the OOOI event.
- Claim: 17. The system of claim 16 , further comprising: a flight management computer (FMC) in communication with the ACARS and the gatelink of the aircraft to receive updated FMC navigation databases.
- Claim: 18. The system of claim 16 , wherein the ACARS is configured to control the gatelink via an interface that includes at least one of a discrete signal and a datalink interface.
- Claim: 19. The system of claim 16 , wherein the ACARS further comprises a memory configured to store an enable gatelink airport list.
- Claim: 20. The method of claim 10 , further comprising: monitoring OOOI events for a departure signal with the ACARS; and upon detection of the departure signal, disabling the gatelink with the ACARS.
