That's fine, but this is really anybody's eye (as far as the viewer is concerned). It could for example be a passenger in 5A on a dc3. It doesn't need to be tied to the FDM. Now the origin location for the 3d model itself is a different story and that probably should be addressed. Right now it is set to whatever the fdm is reporting for lon/lat/alt (plus model offsets that I think aren't being used any more?).
