[Paparazzi-devel] Fix: Engine problems with latest JSBSim CVS version

[Andreas Gaeb]

Hello everybody,

with the latest JSBSim CVS version, the propulsion system seems to need
to be initialized explicitly from the simulation program. With my
airframe, the simulation diverged because I got astronomic RPMs while
the Malolo1 simply dropped to the ground because the engines did not start.

This can be cured by adding the line
FDMExec->GetPropulsion()->InitRunning(-1);
to sw/simulator/sim_ac_jsbsim.c before the RunIC() call in line 224.
This starts up all engines.
I didn't check this with earlier JSBSim versions, but it seems this
function or something similar was called automatically before the
changes from . The explicit call shouldn't hurt in this case.

Best regards,
        Andreas
