Abstract

A method for updating aircraft data is provided. The method comprises: receiving one or more messages at a ground system that one or more aircraft is in a safe state on the ground; selecting one or more aircraft in the safe state to receive a software or database update from the ground system; verifying that the selected one or more aircraft in the safe state is in need of the software or database update; initiating a remote loading of the software or database update to the verified selected one or more aircraft in the safe state; and receiving one or more messages at the ground system from the verified selected one or more aircraft indicating a status of the remote loading.

receiving one or more messages at a ground system that one or more aircraft are each parked at an airport terminal gate;

selecting, by the ground system, one or more aircraft parked at respective airport terminal gates to receive a software or database update from the ground system;

determining, by the ground system, whether each of the selected one or more aircraft will be parked at the respective airport terminal gates for an amount of time required to complete the software or database update;

for each of the selected one or more aircraft determined to be parked at the respective airport terminal gates for the required amount of time, verifying, by the ground system, that the selected one or more aircraft parked at the respective airport terminal gates is in need of the software or database update;

initiating, by the ground system, a remote loading of the software or database update to the verified selected one or more aircraft parked at the respective airport terminal gates, wherein the remote loading comprises;

sending an auto update command from the ground system to the communications management function through a datalink message;

forwarding the auto update command from the communications management function to the line replaceable unit for which the software or database update is needed;

saving the auto update command at the line replaceable unit until a different mode for the line replaceable unit is entered; and

when the different mode is entered, sending a request from the line replaceable unit to the data loader to start the software or database update at the line replaceable unit; and

receiving one or more messages at the ground system from the verified selected one or more aircraft indicating a status of the remote loading.

2. The method of claim 1, wherein the ground system comprises one or more database sources, and an operations center where a data loading software application is located.

3. The method of claim 2, wherein the ground system is in operative communication with a ground infrastructure comprising one or more Wi-Fi access points, a cellular communications infrastructure, or a satellite communications infrastructure.

4. The method of claim 3, wherein the ground infrastructure is configured for operative communication with the one or more aircraft parked at the respective airport terminal gates.

5. The method of claim 4, wherein the one or more aircraft includes an aircraft gateway, which is configured to communicate with the ground infrastructure through a wireless connection.

6. The method of claim 5, wherein the aircraft gateway is in operative communication with an on-board data storage, which operatively communicates with one or more onboard target avionics.

7. The method of claim 6, wherein a message received at the ground system that an aircraft is parked at a respective airport terminal gate, is sent from the aircraft gateway through the ground infrastructure.

8. The method of claim 7, wherein the remote loading of the software or database update is initiated by the data loading software application.

9. The method of claim 8, wherein the software or database update is received by the aircraft gateway and is sent to the on-board data storage.

10. The method of claim 9, wherein the software or database update is sent from the on-board data storage to the one or more onboard target avionics.

11. The method of claim 1, wherein the different mode is a maintenance mode.

12. A system for updating aircraft data on one or more aircraft wherein each of the one or more aircraft comprises:

an onboard gateway configured to wirelessly communicate with ground infrastructure;

a data loader in operative communication with the onboard gateway; and

an avionics system comprising;

a communications management function in operative communication with the onboard gateway and the data loader; and

one or more line replaceable units in operative communication with the communications management function and the data loader, the system comprising;

at least one processor located in a ground operations center; and

a non-transitory computer readable medium including instructions executable by the at least one processor to perform a method for updating aircraft data comprising;

receiving one or more messages at the ground operations center that one or more aircraft are each parked at an airport terminal gate;

selecting, by the processor, one or more aircraft parked at respective airport terminal gates to receive a software or database update;

determining, by the processor, whether each of the selected one or more aircraft will be parked at the respective airport terminal gates for an amount of time required to complete the software or database update;

for each of the selected one or more aircraft determined to be parked at the respective airport terminal gates for the required amount of time, verifying, by the processor, that the selected one or more aircraft parked at the respective airport terminal gates is in need of the software or database update;

initiating, by the processor, a remote loading of the software or database update to the verified selected one or more aircraft parked at the respective airport terminal gates, wherein the remote loading comprises;

sending an auto update command from the ground operations center to the communications management function through a datalink message;

forwarding the auto update command from the communications management function to the line replaceable unit for which the software or database update is needed;

saving the auto update command at the line replaceable unit until a different mode for the line replaceable unit is entered; and

when the different mode is entered, sending a request from the line replaceable unit to the data loader to start the software or database update at the line replaceable unit; and

receiving one or more messages at the ground operations center from the verified selected one or more aircraft indicating a status of the remote loading.

13. The system of claim 12, wherein the ground operations center includes at least one database provider.

14. The system of claim 12, wherein the ground operations center is in operative communication with a ground infrastructure comprising one or more Wi-Fi access points, a cellular communications infrastructure, or a satellite communications infrastructure.

15. The system of claim 12, wherein the ground infrastructure is configured for operative communication with the one or more aircraft parked at the respective airport terminal gates.
