I connect FlightGear with my programm (which is external FDM) through
generic protocol. Generic protocol was changed to accept in/out in binary
form (not corresponding to that one in CVS tree which does binary output
only). From FG property tree I take "/position/ground-elev-m" and my FDM
programm calculates altitude above ground level. Landing gear wheels at FG
moves a bit under the ground, but I think this is because LG struts
compression is calculated in my programm but the airplane model does not
simulate strut compression.
With respect,
Alex
