Terrain Awareness coloring is inhibited in an area immediately
surrounding airports to allow for enhanced visual distinction of those
facilities. If the orientation of runways at the airport can be
determined, then the inhibited area will be based on the outlines of
the runways. Otherwise, coloring will be inhibited in a circular area
around the airport, including airports that have been designated as
an airfield (see page 2-52).
Inhibited Terrain Awareness Coloring
Terrain Awareness coloring can be turned off via the Setup Page
(see page 4-63), but that setting will not affect Terrain Awareness for
obstacles, which cannot be turned off.
