Err..umm..foul! ;-)  If you look at the outputs in "/position/altitude-ft" you
will note disagreement about where the ground is at starting KSFO.

JSBSim seems to think KSFO is a 0 elevation by the way.  If it is, then Yasim
is wrong, since it reports a different value for alt and alt-agl on startup at
KSFO.  The other FDM's have a completely different take on the situation
reporting the elevation a foot or two lower than JSBSim and Yasim.

Basically it isn't that much of a problem if FDM's disagree, but the aircraft
model offsets will need to be set for any discrepency from the default FDM if
you use another FDM.

Best,

Jim
