Garmin G1000 Pilot's Manual page 287

To display terrain and obstacle data on any page other than the Terrain Proximity Page, press the MAP Softkey,
then press the TERRAIN Softkey. Obstacles with heights greater than 200 feet above ground level (AGL) are
displayed in three color levels (Table 6-6). The G1000 adjusts colors automatically as the aircraft altitude changes.
Terrain Proximity may also be deselected from the Inset Map without affecting the terrain display on the MFD
maps.
Obstacles are displayed only at certain map zoom ranges, on certain maps, and will only be displayed if an
obstacle database is loaded on the SD card. In addition, all map zoom ranges are dependent on the zoom range
setting in the Navigation Map. If the zoom range on the Navigation Map is adjusted to below 20 nm, the highest
zoom range on all other maps is also adjusted proportionally.
Table 6-5 shows the map pages and the highest zoom range at which obstacles are displayed.
LIMITATIONS
Terrain Proximity displays altitudes of terrain and obstructions relative to the aircraft position and altitude
with reference to a database that may contain inaccuracies. Terrain and obstructions are shown only if they
are in the database. Terrain and obstacle information should be used as an aid to situational awareness. They
should never be used to navigate or maneuver around terrain.
Note that all obstructions may not be available in the terrain and obstacle database. No terrain and obstacle
information is shown without a valid 3-D GPS position.
