Excellent. This bug has been annoying me for a long, long time. I think the solution should be simpler, though. Right now, the scene graph looks (from memory) like this: Root/Eye -> Scenery Centroid -> Aircraft Origin -> Cockpit -> ... So the local cockpit coordinates get double-transformed to the centroid and back, losing precision in the process. That comes out to roughly 1 part in a million at single precision, which over a ~1km tile can be as much as a few millimeters, which is several pixels of screen space in a small cockpit. But the solution should be as simple as reorganizing the scene graph: Root/Eye -> Scenery Centroid -> scenery... -> Aircraft Origin -> Cockpit -> ... I wonder if your fix isn't more complicated than it needs to be.
