This is because of the skid-slip indicator problem with JSBSim. Some
code in stream.cxx locks the compass during severe slip/skids.
JSBSim seems to output much larger acceleration vectors in the Y
direction than the other fdms, and thus the skid/slip ball doesn't
work properly. Hence the mag compass also doesn't work properly!!
As a temporary hack to get the compass working, change the following
conditional in steam.cxx to if(0)
if ( fabs(the_TC_rad) > 0.2 )
{ /* Massive sideslip jams it; it stops turning */
the_MH_degps = 0.0;
the_MH_err = fgGetDouble("/orientation/heading-deg") -
the_MH_deg;
} else
Cheers - Dave
