Distance makes a huge difference.
That's true for position jitter, but not for orientation. But even if it's position, the jitter should still cause a change in position of the scenery, not the cockpit. Remember that the cockpit *is* the aircraft -- no matter what the position is, it is always nailed down to the pilot's viewpoint position by definition. But the scenery is always perfectly fine, even the runway right next to the aircraft (not much farther than the cockpit) is rock solid. Really, I don't see any other options -- whatever is causing the jitter is inside the model's scene graph, and not under the scenery. Since the FDM output goes into both, you have to rule it out (or you can put printf's in the update routines and verify that inter-frame distances are never more than 0.1mm or so). Andy -- Andrew J.
