I haven't even got pre2 to run yet! Curt: if you've not done it yourself yet, the file data/Huds/Instruments/Default/runwayinstr.xml has duff permissions. There's one thing I really like to see solved preferably before 0.9.9 (but it is a must for 1.0) and that's the sun/moon azimuth calculation code to be replaced. That's certainly not getting in before 0.9.9! Turns out to be wy more tricky than it looked. It would seem that the entire handling of sun/moon azimuth/altitude as it's done now in flightgear needs replacing, with the alt/az calculations themselves done in Simgear. Everything else to do with the ephemeris happens in Simgear. To some extent, I'd argue that the whole ephemeris thing needs splitting out from Simgear into Ephemlib or something. After all, there are quite a few planetarium programs out there, each with its own unique ephemeris calculations. It would make sense to try and draw them together. There's little incentive for anyone writing an astronomical program to want to use Simgear for the ephemeris calculations because it comes with so much flightsim-related baggage. But that's for another day, another year.

Ok, now I tried the brute force method, eliminate every function which isn't really needed or which is supplied by SimGear already. I got a version that doesn't use any of the offending code with one small glitch; the azimuth is offset by 90 degrees.

If you are talking about code from xglobe ( src/Time/sunpos.cxx, moonpos.cxx) , which licence is quite problematic, I hope it would be solved as soon as possible. This licence issue causes that FG is not included in box SuSE Linux. If fixed, it can be distributed within next SuSE release.

I got lost in the mass of 3D vector stuff that was working out how to light the scene and shift the skyglobe based on knowledge (from Xearth) of what point on earth had the sun directly overhead! I got as far as replacing the Xearth stuff with a simple get the sun's alt and azim for a given place on earth routine, but couldn't untangle the rest.
