Hello Dev team,
Are there projects using FlightGear as the ``engine'' of a simulator
with cockpit mockup, multiple projectors, head down display and and
possibly a motion platform?

To be fair, YASim is not necessarily less accurate,

We are a bit behind on this part. There is a project called OpenGC that
has been working with FlightGear, but I don't know the current
Yeah, but the windtunnel or flight-test data woudl include the
individual coefficients in one single value. This means that if there is
data for -180 ... +180 degree AOA and Yaw JSBSim (and UIUC) woudl be
more accurate compared to YASim.
That said, YASim is realy a good alternative for most

Does jsbsim also take yaw angle into account (fuselage drag)? I.e., is
it possible to perform a slip (haven't had a real chance to try yet due
to lack of pedals). For yasim I take it it is possible.
Yes. The sideslip angle is called beta, and several coefficients

I can think of a couple of situations where YASim would have advantages -
*at*present*:
- Calculating any force or moment that is a result of rotational motion
while the aircraft is at zero translational velocity.
- Clearly, any condition that is not covered by

Note that JSBSim would get all of this for free simply by allowing
coefficients to be (optionally) specified for individual surfaces,
each with its own orientation. All JSBSim would have to do is sum up
the moments and forces (mostly forces) for the collection of surfaces.
I think we all

This is actually the first time I've looked at this video, but it is
quite nice to see FlightGear in action this way:

Do you mean the position/orientation, the shape, or the aerodynamic
behaviour?
All the best,

The aero behavior. Coefficients are generally apply only to the whole

means its very hard to split them up arbitrarily.
