Subject: Change nav->get_elev() to nav->get_elev_ft() to convey the actual units
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=2caa017a79761637f04375eaa7642a5d3483f66d;p=flightgear.git

Change nav->get_elev() to nav->get_elev_ft() to convey the actual units
explicitely.  This value has always been feet, but there were a couple places
in the code that assumed this elevation was meters.  The result was that you
could park directly over the top of the Black Forest VOR (112.50) NE of KCOS
and get a dme reading of 2.5 or so.  This problem is now resolved.
