The c.g. isn't a fixed location. It moves when you burn fuel, load cargo or drop bombs, sometimes quite significantly. When I looked, actually, all of the model stuff was relative to the airfame. I can promise that YASim's position output is that of the aircraft nose (well, not necessesarily the nose, but all the current aircraft configurations use this by convention), and I'm all but certain JSBSim works the same way. Which parts are still using the c.g.? we should fix that. Andy -- Andrew J.
