Re: [Flightgear-devel] Startup position offsets (fg_init)

2008-08-25 Thread Curtis Olson
Hmmm, ok I suppose that is possible. I have done this with an external FAA certified flight dynamics model, but I am letting the flightgear code compute the final longitude and latitude and altitude and just passing that over. This has worked as recently as 2 weeks ago. I don't know that I've tr

Hi James, I think this was all done intentionally because it's quite common to want to start a flight simulator on a 5 or 7 or 10 mile approach so you can practice ILS landing. The start-offset-m value I believe was added later to account for the difference in aircraft size. A starting position
