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
