This is currently normal behavior, but it is a limitation of the current code. Currently, FlightGear finds the node that is nearest the beginning (takeoff) of end (landing) of the runway, and creates a route from/to the parking position using these two points. We are moving towards a more sophisticated runway exit strategy: Last year at LinuxTag, Thomas Foerster and I discussed the idea of adding a performance database that could be used to determine stopping distances, and I'm currently working on adding support for runway "entrance/exit" points. Ideally, I'd want taxidraw to set these automatically, but this is still on my TODO list. Many of the bits and pieces are already in place, but the whole system needs more integration. I hope to address these issues, as I'm moving forward with integrating the AI / ATC code. > > Another question: Should I use a rwyuse.xml file?

Using a rwyprefs file will give you some more control over runway assignments, which might come in handy if you want to do more sophisticated stuff like parallel takeoffs / landings, or assign separate runways for general aviation / commercial and military traffic. If you want the runway choice to be more determined by the wind, you could try to play with the tailwind and crosswind parameters. In particular, setting these to smaller values would allow the wind to have a bigger influence. I realize that there isn't much documentation on the runway prefs file. have a look at one for EHAM, which is the most compliated one I have. If you have any questions regarding this file, please let me know and I'll try to hack together some documentation.
