Hi Mike, There are actually two different AI systems in FlightGear. The first one was written by David Luff and is called AI-Traffic. This system puts AI Cessnas in the traffic pattern at the smaller airports. I'm not familiar with this one, but there are others on this list who are. I don't know if it's possible for this system to create traffic at KSFO. The second AI system is called AI, and is the system that creates a wide array of AI objects, including ships, storms, thermals, static objects, airplanes, and ballistic objects. This system is controlled by an AI scenario file (XML). You will find several demo scenario files in the directory data/Data/AI. Each scenario file defines one or more AI objects. You may have as many AI objects as you like in each scenario, but there can only be one scenario running at a time. Overall control of this AI system is done in preferences.xml under the <ai> section. Here you turn the system on and define which AI scenario file you want to run. This causes the scenario to start at the start of the simulation, and it will run until the simulation ends. If you look at the aircraft_demo.xml scenario file you'll see how to create a 737 AI aircraft. To have this airplane fly approaches to 28L you just need to change the <flightplan> to KSFO_ILS28L.xml. (Note that the flight plans are in the FlightPlans subdirectory, and you can make your own to put in there). A new feature, available only in the CVS version of FlightGear so far, is the <repeat> tag, which will cause the aircraft to vanish at the end of its flight plan and reappear at the beginning, which it will do indefinitely. You do this by setting <repeat> to any non-zero value, for example <repeat>1</repeat>. That's a quick look at it. There's a document on this system at the wiki (which doesn't display properly), but I need to write an HTML doc for the Docs collection. Let me know if you have any questions.
