Does anyone know the meaning of the parameters for the eyepoint tag in the aircraft.cfg file?

That moves your viewpoint around in VC. There's three parameters. The first is measured forward/backward from the CG. The second left/right. The third up/down. So, if you want to lower the pilots viewpoint, decrease the third number. You want to move forward, increase the first number. I think that's how it works since I just made a vertical adjustment on one yesterday. I decreased the third number and the pilot view was lower in the virtual cockpit.
