Hi Torsten,
I just created a merge request for syncing FlightGear with JSBSim prior to
the release 2.10 https://gitorious.org/fg/flightgear/merge_requests/40
I hope it is no already too late...

Hi all,
Just to let you know that Jon fixed a bug in JSBSim that affected the
tank inertia calculations. I think it is worth updating both 2.8.0 and
2.9.0
The fix has been applied on the file
src/FDM/JSBSim/models/FGPropulsion.cpp and is available on JSBSim CVS
repository.
Regards,
Bertrand.

A number of issues have been reported in the bug tracker #184 about

I could reproduce the bug on my computer as well.
There seems to be some confusion about what the

update the initial conditions (IC) of JSBSim. And, when the IC are

Enough of that please.
I would be grateful if both of you AJ MacLeod and Alasdair ould stop
polluting everyone's mail box with your "discussion".
Thank you very much.

The ultimate all-in-one performance too
Correct. JSBSim itself makes no distinction between ground materials (hence
the reason why some aircrafts are able to land on water). This can however
be managed with Nasal scripts. So I would say that this issue is likely
located in one of the C172 Nasal scripts.

Hi all,
I think I have a final bug fix for JSBSim reset issues (bug #204 and
#222). I have investigated James Turner's fix and tried to understand
why it fixes the issue in every case but for gliders.
NaNs (bug #222) were basically generated because the method
JSBSim::unbind() was not implemented

the Flight Gear CVS tree under my project and that the only commit I

commit intended for ? Furthermore, do you honestly th
