Airport/Heliport Terrain “Cutouts”
For software version 4.00 and later: when con-
figured for helicopters (the helicopter icon will be
displayed), black, circular or oblong “cutouts” will be
displayed on the Terrain Page around airports and heli-
ports, to enhance viewing of the information displayed
for those locations. The Terrain legend (shown in the
lower right of the display on the Terrain Page) defines
the color black as -500 ft. However, this does not apply
to the black cutouts surrounding the airports and
heliports.
