Subject: Compute /position/altitude-agl-ft in MagicCarpet FDM
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=e0d30cc412a32207578d6d020da363eb6a229f9e;p=flightgear.git

Compute /position/altitude-agl-ft in MagicCarpet FDM

Add the same computation of /position/altitude-agl-ft for
the magic carpet fdm as it is used in the ufo fdm. This
property is used in the environment controller to interpolate
between the individual weather-condition layers.
