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
tried this with any internal FDM's recently though.

Can you give me an example that fails?  This initial position code is a bit
complicated since it perhaps tries too hard to decide what you *want* based
on limited or missing inputs, but as far as I know it does work correctly.

Regards,

Curt.
