Map Datums
The Map Datum section of the System Setup Page allows
selection of map datums to be used by the G1000 from a
list of datums available in the current aviation database
(See Appendix D for a list of available map datums).
NOTE: Per TSO C129a, the WGS-84 map datum should
be used in the United States. For use outside the U.S.,
select the geodetic datum required by that country.
To select a Map Datum:
1. 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 ‘MAP DATUM’ field.
4. Turn the
small FMS
knob to display the Map
Datum list.
5. Turn the
small or large FMS
knob to highlight
the new datum.
6. Press the
ENT
key.
Airspace Alerts
The Airspace Alerts fields allow the pilot to turn the
controlled/special-use airspace message alerts on or
off. This does not affect the alerts listed on the Nearest
Airspaces Page or the airspace boundaries depicted
on the Navigation Map Page. It simply turns on/off the
warning provided when the aircraft is approaching or
near an airspace. An altitude buffer is also provided which
“expands” the vertical range above or below an airspace.
For example, if the buffer is set at 500 feet, and you are
more than 500 feet above or below an airspace, you will
not be notified with an alert message; if you are less than
500 feet above or below an airspace and projected to enter
it, you will be notified with an alert message. The default
setting is 200 feet.
The Airspace Alerts section of the System Setup Page
displays the following information:
• Class B TMA airspace alert setting
• Class C TCA airspace alert setting
• Class D
• Restricted airspace alert setting
• MOA
• Other airspace alert settings
• Altitude buffer distance setting
The Airspace Alerts section of the System Setup Page
allows for the following operations:
• Selecting class B TMA airspace alert setting (on,
off)
• Selecting class C TCA airspace alert setting (on,
off)
• Class D (on, off)
• Selecting restricted airspace alert setting (on, off)
• Selecting MOA (on, off)
• Other airspace alert settings (on, off)
• Selecting altitude buffer distance setting
