Ah, now I think I understand what you mean. I agree, the model placement looks dumb. But it's correctly dumb. If we were modeling off-runway ground handling, the aircraft would be bouncing (or sinking!) because YASim really *does* think the aircraft is off the runway. Moving the model origin only fixes the problem on the screen. The bug you are trying to fix is in the runway placement initialization code, not the model geometry. Right now it puts the origin just barely past the threshold, which is fine for light planes but not for jumbo jets. Even if you were going to try to do the Right Thing, you would have to deal with aircraft geometry. Real aircraft pull onto the runway with their nosegear on the taxi lines, and have to pull forward by different amounts depending on their gear geometry. Just moving the aircraft origin will never be sufficient. I agree, we need a per-aircraft runway startup offset (which would basically be the length of the fuselage). Alternatively, we could pick the *tail* of the aircraft as the coordinate origin. That would behave correctly under these conditions. Andy -- Andrew J.
