IRSPACE LERTS
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. Alerts for the following airspaces can be turned on/off in the Airspace Alerts Box:
• Class B/TMA
• Class C/TCA
• Class D
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 will not be 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 System Setup 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) Enter an altitude buffer value and press the ENT Key.

RRIVAL LERTS
The Arrival Alert Box on the System Setup Page allows arrival alerts to be turned on/off and the alert
trigger distance set. An arrival alert can be set to notify the pilot with a message upon reaching a user-
specified distance from the final destination (the direct-to waypoint or the last waypoint in a flight plan).
Once the set distance (up to 99.9 units) has been reached, an "Arrival at [waypoint]" message is displayed
in the PFD Navigation Status Box.
