ISPLAY NITS
The Display Units Box on the System Setup Page allows configuration of the measurement units used for
the following displayed data:
• Nav angle (auto, true)
• Distance and speed (metric, nautical)
• Altitude and vertical speed (feet, meters)
• Barometric pressure (inches of mercury,
hectopascals)
For the navigation angle, if 'Auto' is selected, all track, course, and heading information is corrected to the
computed magnetic variation, shown as MAG VAR in the Display Units Box . The "True" setting references
all information to true north.
Changing a display units setting:
1) Use the FMS knob to select the System Setup Page.
2) Press the FMS Knob momentarily to activate the flashing cursor.
3) Turn the large FMS Knob to highlight the desired field in the Display Units Box.
4) Turn the small FMS Knob to select from a list of measurement units.
5) Press the ENT Key when the desired unit is highlighted.
6) To cancel the process without changing the units, press the CLR Key.

Per TSO C129a, the WSG 84 map datum should be used in the United States. For use outside the U.S.,
NOTE:
select the geodetic datum required by that country. See Appendix E for a list of available map datums.
The aviation database contains over 100 map datums to adjust position reading, making it conform to
specific paper charts. The default datum setting is WSG 84. If charts based on another datum are being
used, the G1000 should be set to use the same datum. Using a map datum that does not match the
paper charts can result in significant differences in position information. If paper charts are being used
for reference only, the G1000 still provides correct navigation guidance to the waypoints contained in the
database, regardless of the datum selected.
The Map Datum Box on the System Setup Page allows selection of the map datum to be used by the
G1000 from a list of datums available in the current aviation database.
Selecting a Map Datum:
1) Use the FMS knob to select the System Setup Page. Press the FMS Knob momentarily to activate the flashing
cursor.
2) Turn the large FMS Knob to highlight the datum in the Map Datum Box. Turn the small FMS Knob to display
and scroll through the list of available map datums.
3) Press the ENT Key when the desired datum is highlighted.
