Are you thinking of doing real-world flights? If so, is there a good place to harvest that data? Thoughts on how to convert it into flightplans of the style you use? Many ideas, but no real solutions yet. I have made a few example traffic files by hand, based on airline and airport time tables and some imagination. Flight plans are currently autogenerated by FlightGear. Nothing fancy, but just a set of waypoints connecting the center point of the departure and arrival airports, using a runway for take-off. I don't know of any good data source for traffic schedules. Eventually, I'm hoping to be able to use the data from projectAI (http://www.projectai.com), using a conversion tool that exports their data into a FlightGear format xml file. I'm unable to contact them, however, because their contact email addresses appear not to be working. I'm thinking about making my conversion script available for download, so that users could download their own favorite PAI files and convert them to flightgear format. AFAICT, that wouldn't be in violation of their licence. I've also started writing a small tutorial on creating traffic files, but that's not ready for release yet. Given the work that still needs to be done, there's clearly no urgency to this. I'm just curious what direction you're going . . . Aside from finishing the tutorial and updating the pai-conversion script, I'm trying to add more realistic airport parking and taxi behavior. Once that's in place separation handling would be next. This is indeed not something that I expect to finish off soon. Anyway, cool stuff. -c Cheers, Durk ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d

AFAIK the offer their timetables in an electronic format to download. At least they have them packaged for PDAs and a very cool screen saver where you can see all flights at their current (predicted) position.

Erik I've actually had it up to close to 1200 AI aircraft. :-) It does take a hit on performance. With the traffic manager enabled, Initial performance on my system is about 30fps, which dropped to about 13fps once more than 1130 AIModels were created. It's not likely though that release versions of FlightGear will have to handle so much AI traffic in the near future though. The traffic file I used for testing is one that I converted from projectAI data, which I can't release without their permission and since the main contact email addresses on the projectAI website appear to be non-existent I wouldn't even know how to ask them for permission. Second, in the current version of the code, *every* aircraft that is within 500nm of the user is created as an AIModel. This covers a huge area, and can most likely be shrunk considerably. Third, once an AIModel is created, it is never released again by the AIManager once it flies out of user range again. Modifying the bahavior of the last two points is moving up my prioritylist pretty rapidly.
