Hi. Is there something other than what I'd expect done in determining the value of the property /position/ground-elev-m ? Is it taken from the terrain point immediately below the aircraft; or below it in some cone of some angular size, or something like that?
I ask because at fixed lat/lon, the value you get for this property
depends on the altitude you're at when you check it. If you're at
16,000 feet and you check this property, the value you get is different
from if you're at 5,000 feet over the exact same lat/lon. The difference
is normally not that large -- a few centimeters, typically. But sometimes
it's a meter or more. This matters for e.g. scripts used to place scenery
objects that move from point to point around the landscape and measure
this quantity through the telnet interface, such as what Curt's written
and what Jon and I are using. In my case, one out of a hundred or so
airport signs is half-buried or slightly levitating . . .
