Garmin G1000 NXi Pilot's Manual page 183

The Nearest Airspaces Page, Airspace Alerts Window, and Airspace Alerts on the PFD provide additional
information about airspaces and the location of the aircraft in relationship to them.
The Airspace Alerts Box allows 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 the aircraft is more than 500 feet above/below an airspace, an alert message is
not generated, but if the aircraft is less than 500 feet above/below an airspace and projected to enter it, the pilot
is notified with an alert message. The default setting for the altitude buffer is 200 feet.
Changing the altitude buffer distance setting:
1) Use the FMS Knob to select the Aux - System Setup 1 Page.
2) Press the FMS Knob momentarily to activate the flashing cursor.
3) Turn the large FMS Knob to highlight the altitude buffer field in the Airspace Alerts Box.
4) Use the FMS Knob to enter an altitude buffer value and press the ENT Key.
5) Press the FMS Knob to remove the flashing cursor.
Turning an airspace alert on or off:
1) Use the FMS Knob to select the Aux - System Setup 1 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 Airspace Alerts Box.
4) Turn the small FMS Knob clockwise to turn the airspace alert On or counterclockwise to turn the alert Off.
5) Press the FMS Knob to remove the flashing cursor.
Map ranges for the airspace boundaries are selected from the Airspace Group in the Map Settings Menu. See
Table 5-3 for the default and maximum ranges for each type of airspace and the symbol used to define the airspace
area.
