At UKUUG Linux 2001 in Manchester, the open source flight simulator FlightGear was proudly presented and demonstrated to an enthusiastic audience. Today it is even better.
Customization has become significantly easier by use of XML files. The range of aircraft and flight data models has increased significantly. The user and developer base has expanded. Hardware is more powerful. Much better terrain data is now available.
Improvements from other open source projects benefit it too. eg, the 2.6 kernel improves latencies, important for co-simulation performance.
This talk introduces FlightGear, It discusses challenges in terms of recent advances, applications, and current work in progress.
