AIRSPACE ALERTS

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 MFD 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

• Restricted

• MOA (Military)

• Other airspaces

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) 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) Turn the FMS Knob to enter an altitude buffer value and press the ENT Key.
