This discussion seems to be a little more complicated than it needs to be. I realize c.g. (where g.=gravity) moves around. And I'll wait until the need to know comes up before asking how to determine where the origin is on JSBsim models. This is what I suggested earlier to fix the 747: >>>>> Either move the FDM origin back to c.g. (or some place not at one end of long body aircraft), or create an offset for the startup position on the runway configurable per aircraft. <<<<< The reason for the suggestion is this: When the 3D model origin is set at the nose or cockpit, the aircraft is too far back on the runway at startup. So far back that the main gear is not on the pavement. It looks stupid. Even as it is currently, it sits too far back. If we can agree how to fix that problem, then I can make the adjustments to the 3D model.
