Abstract

An air traffic information display system includes a server having data manager. The data manager includes a first interface connected with a first database server and a plurality of second interfaces connected to a plurality of clients. The data manager includes a subscription list for the plurality of clients for providing the clients with data updates. The subscription list also includes criteria for each client. The data updates are distributed based upon the criteria of each client.

Claims

1. An air traffic information display system comprising:

a data manager including a first interface and a plurality of second interfaces;

a first database server connected to the data manager via the first interface; and

a plurality of clients capable of coupling to the data manager via the plurality of second interfaces;

the data manager including a subscription list for the plurality of clients for providing data updates in accordance thereto.

2. A system as claimed in claim 1 wherein the data manager is a primary data manager and further including an alternate data manager capable of coupling to the primary data manager via one of the plurality of second interfaces.

3. A system as claimed in claim 1 wherein one of the plurality of clients is an external input/output server.

4. A system as claimed in claim 1 wherein at least one of the plurality of clients is a workstation having a display screen.

5. A system as claimed in claim 1 wherein the plurality of second interfaces each include a server data manager.

6. A system as claimed in claim 1 wherein the plurality of clients each include a client data manager.

7. A system as claimed in claim 1 wherein the data manager includes a flight data entry object list.

8. A system as claimed in claim 1 wherein the data manager includes a socket connection list.

9. A system as claimed in claim 1 wherein the data manager includes a system list.

10. A system as claimed in claim 1 wherein the first database server includes first tables for current data and second tables for logging changes to current data.

11. A system as claimed in claim 10 wherein the first tables include a flight data table.

12. A system as claimed in claim 10 wherein the first tables include an airport system table.

13. A system as claimed in claim 10 wherein the first tables include a system table.

14. A system as claimed in claim 10 wherein the second tables include a flight data table.

15. A system as claimed in claim 10 wherein the second tables include an airport system table.

16. A system as claimed in claim 10 wherein the second tables include a system table.

17. A system as claimed in claim 1 wherein the first interface is ODBC.

18. A system as claimed in claim 1 further comprising a gateway database server.

19. A system as claimed in claim 18 wherein the gateway database server includes third tables for receiving updates from the second tables.

20. A system as claimed in claim 19 wherein the gateway database server includes fourth tables for logging copies of the third tables.

21. A system as claimed in claim 18 wherein the gateway database server includes fifth tables for storing movements.

22. A system as claimed in claim 21 wherein the gateway database server includes a module for calculating movements in dependence upon changes in the third tables.

23. A method of displaying air traffic information comprising the steps of:

maintaining a list of subscribers for data updates;

receiving a data update request;

changing the data in accordance with the request;

storing the changed data; and

providing the changed data in accordance with the list of subscribers.

24. A method as claimed in claim 23 wherein the step of maintaining a list of subscribers includes storing criteria for each subscriber in the list.

25. A method as claimed in claim 24 wherein the step of providing the changed data includes providing only the data determined by the criteria.

26. A method as claimed in claim 23 wherein the step of storing includes storing the changed data in first tables.

27. A method as claimed in claim 23 wherein the step of storing includes storing a log of data change transactions in second tables.

28. A method as claimed in claim 26 wherein the first tables include a flight data table.

29. A method as claimed in claim 26 wherein the first tables include an airport system table.

30. A method as claimed in claim 26 wherein the first tables include a system table.

31. A method as claimed in claim 27 wherein the second tables include a flight data table.

32. A method as claimed in claim 27 wherein the second tables include an airport system table.

33. A method as claimed in claim 27 wherein the second tables include a system table.

34. A method as claimed in claim 27 wherein the step of storing includes storing updates from the second tables in third tables.

35. A method as claimed in claim 34 wherein the step of storing includes logging copies of the third tables in fourth tables.

36. A method as claimed in claim 34 wherein the step of storing includes calculating movements in dependence upon changes in the third tables.

37. A method as claimed in claim 36 wherein the step of storing includes storing movements in fifth tables.
