heading, I still see 0 in the /velocities/airspeed-kt property.
Hmm, metar only updates the weather properties (wind, etc), adjusting
the (indicated) airspeed based on that is up to the FDM's. Which FDM are
you talking about?
I see this with the UFO and the default (c172p based on JSB). c172 tested
Don't expect the UFO FDM to do anything more than move you around in the
scenery a bit. So that's not a very good platform to test these kind of
changes.
on the ground, pointed to different direcion (wind on the nose and wind on
the wing), UFO on the ground and 1000AGL, still or flying (when I am
saying still I mean that my ground speed and my airspeed were both zero,
even with the thunderstorm turned on). If it's a bug, then, with the UFO
it is probably not worth fixing, though :-)
The new JSBSim does zero-out the wind forces while stationary on the
ground to prevent ground jitter. That might be the cause of what you are
seeing.
