Jon is still waiting on me to put together a thin (but conformant) XML parser for JSBSim, probably a stripped-down version of Expat. Right now, Jon's just using a sort-of-XML-like lexical scanner that's easily confused. There probably won't be any progress on external inclusions until a general config-file overhaul, but I'd think it would be a high priority. > Also, does JSBSim accept aero data in the body axes as well as the > stability axes? I'm not sure, but I think it doesn't. Jon or Tony will have to provide more information. > Can JSBSim do 3D interpolation for, say, data as a function of angle of > attack, sideslip and flaps?

Jon and Tony have talked about extending it to allow n-dimensional tables. It might be necessary to try to uncouple some of the data for now, though.
