Abstract

Methods and systems for managing computer system configuration data are provided. The method includes staging the configuration data in a staging memory accessible to a first application, selecting a path for a transfer of the configuration data from the staging memory to a target memory, emulating a hardware data loader using a second software application adapted to control a transfer of the configuration data from the staging memory to the target memory, and transferring the configuration data from the staging memory to the target memory using the emulator. The method further effectively expands a memory capacity of a Flight Management Computer by providing swappable memory capacity such that a re-certification to Federal Aviation Administration standards of the Flight Management Computer is not triggered.

Claims

1. A method of managing computer system configuration data comprising:

staging the configuration data in a staging memory accessible to a first application;

selecting a path for a transfer of the configuration data from the staging memory to a target memory;

emulating a hardware data loader using a second software application adapted to control a transfer of the configuration data from the staging memory to the target memory; and

transferring the configuration data from the staging memory to the target memory using the emulator.

2. A method in accordance with claim 1 wherein staging the configuration data comprises staging a plurality of selectable configuration data sets in the staging memory.

3. A method in accordance with claim 2 wherein a Flight Management Computer system includes a memory that is substantially constrained in capacity to a current capacity and wherein staging a plurality of selectable configuration data sets in the staging memory comprises effectively expanding a memory capacity of the Flight Management Computer such that a recertification to Federal Aviation Administration standards of the Flight Management Computer is not triggered.

4. A method in accordance with claim 1 further comprising generating a notification that the configuration data is staged in the memory and ready to be installed.

5. A method in accordance with claim 1 wherein selecting a path comprises selecting the staging memory using a first data load switch.

6. A method in accordance with claim 1 wherein selecting a path comprises selecting the target memory using a second data load switch.

7. A method in accordance with claim 6 wherein the second data load switch comprises a hardware switch and wherein selecting a path comprises selecting the target memory by physically manipulating the second data load switch by a user.

8. A method in accordance with claim 1 wherein selecting a path comprises initiating a configuration data load mode on the target memory.

9. A method in accordance with claim 1 further comprising:

entering a maintenance mode in the first application; and

initiating a second application adapted control loading the configuration from the first memory to the second memory by emulating a hardware data load device.

10. A method in accordance with claim 1 wherein emulating a hardware data loader comprises entering an emulation mode for a selectable hardware data loader.

11. A method in accordance with claim 10 wherein emulating a hardware data loader comprises entering an emulation mode for an ARINC 615 compliant data loader.

12. A method in accordance with claim 1 wherein emulating a hardware data loader comprises emulating an ARINC 615 compliant data loader.

13. A method in accordance with claim 1 further comprising monitoring the transfer of the configuration data from the staging memory to the target memory.

14. A method in accordance with claim 1 further comprising:

receiving an error message from the target memory if a transfer of the configuration data from the staging memory to the target memory fails; and

alerting an operator of the data transfer failure.

15. A method in accordance with claim 1 further comprising re-initiating a transfer of the configuration data from the staging memory to the target memory.

16. A method in accordance with claim 1 wherein transferring the configuration data comprises transferring a navigational database.

17. A method in accordance with claim 1 wherein transferring the configuration data comprises reporting a successful transfer of configuration data.

18. An Electronic Flight Bag system comprising:

an electronic data storage for storing and structuring data stored in the Electronic Flight Bag;

a user interface for accessing the information in the flight bag; and

a cockpit information management aid comprising a software code segment programmed to emulate a hardware data loader, said code segment further programmed to load protocols and functions to permit the Electronic Flight Bag to manage data transfers from at least one source external to the aircraft to and from at least one aircraft line replacement unit.

19. An Electronic Flight Bag system in accordance with claim 18 further comprising a hardware switch configured to select the at least one aircraft line replacement unit.

20. An Electronic Flight Bag system in accordance with claim 18 wherein said software code segment is programmed to emulate a ARINC 615 compliant data loader.

21. An Electronic Flight Bag system in accordance with claim 18 wherein said software code segment is programmed to selectably emulate a plurality of hardware data loaders including an ARINC 615 compliant data loader.

22. An Electronic Flight Bag system in accordance with claim 18 wherein said Electronic Flight Bag is configured to manage a data transfer from a staging memory to a target memory in an aircraft line replacement unit.

23. An Electronic Flight Bag system in accordance with claim 18 wherein a Flight Management Computer system includes a memory that is substantially constrained in capacity to a current capacity, said Electronic Flight Bag system is further configured to effectively expand a memory capacity of the Flight Management Computer such that a re-certification to Federal Aviation Administration standards of the Flight Management Computer is not triggered.

24. An Electronic Flight Bag system in accordance with claim 18 wherein said Electronic Flight Bag is configured to determine that a data transfer to the staging memory is complete.

25. An Electronic Flight Bag system in accordance with claim 18 wherein said Electronic Flight Bag is configured to determine that a data transfer from at least one source external to the aircraft to the staging memory is complete.

26. An Electronic Flight Bag system in accordance with claim 18 wherein said Electronic Flight Bag is configured to determine that a data transfer from the staging memory to said target memory is complete.

27. An Electronic Flight Bag system in accordance with claim 18 wherein said Electronic Flight Bag is configured to transmit a transfer complete message determine that a data transfer from the staging memory to said target memory is complete.

28. An aircraft onboard computer data loading system comprising:

an onboard computer system comprising a communications system configured to receive onboard systems configuration data from a source external to the aircraft;

a staging memory configured to receive the configuration data from the communications system;

an avionics units comprising a target memory configured to receive the configuration data from said staging memory; and
