[Flightgear-users] X-Plane/FlightGear Aircraft

2005-10-17 Thread T J
Is it possible to download aircraft models designed for use with X-Plane 
(any version) and use them in FlightGear? It would be good if you could do 
this. If somebody knows how to add X-Plane Aircraft to FlightGear, could 
they please tell me what to do.


Thanks

No this isn't possible. While it might be possible to convert the 3d 
model to a FlightGear supported format, the X-Plane flight model is not 
like anything FlightGear supports. YASim might be the closest match, but 
as far as I know it's still not close enough to be able to convert it go 
YASim properly.

It might be a fun project for someone, if they can get their hands on 
the x-plane format spec.  You could write an offline converter that 
loads an x-plane aircraft and then spits out a yasim config file.  You'd 
have to prompt for the approach/cruise configuration numbers which the 
yasim solver needs so it can match published performance *exactly* 
(hehe, just playing the marketing hype game here a little.) :-)  Then 
you could also extract the 3d model information and you could convert it 
to a .ac file with .xml animation wrappers for FlightGear.  That sounds 
like a good medium-difficulty project if anyone out there has nothing 
better to do. :-)
