OK, here's how I had understood things: 1. The FDM sets the plane's lat/lon/alt to the ideal pilot viewpoint. 2. /sim/view/pilot/*-offset-m are properties controlled by the user and/or the view manager, and are added to the lat/lon/alt supplied by the FDM. Here's how Andy understands things: 1. The FDM sets the plane's lat/lon/alt to the origin, which is any arbitrary point on the plane's body. 2. /sim/view/pilot/*-offset-m are properties controlled by the FDM to give the offsets from the origin to the ideal pilot viewpoint. I'd like to reserve the /sim/view properties literally for allowing the user to move around inside (or outside) the plane. If my #1 is not correct, perhaps we should all the FDMs to put offsets somewhere under the FDM hierarchy.
