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?).
