Nearest Airspace Page

The last page in the NRST group, the nearest airspace page, will alert you to as many
as nine controlled or special use airspaces near or in your fl ight path. Alerts are provided
according to the following conditions:
• If your projected course will take you inside an airspace within the
next ten minutes, the alert message "Airspace ahead -- less than 10 minutes" will
appear. The nearest airspace page will show the airspace as "Ahead".
• If you are within two nautical miles of an airspace and your current course will
take you inside, the message "Airspace near and ahead" will appear. The nearest
airspace page will show "Within 2nm of airspace".
• If you are within two nautical miles of an airspace and your current course will not
take you inside, the message "Near airspace less than 2nm" will appear. The near-
est airspace page will show the airspace as "Ahead < 2nm".
• If you have entered an airspace, the message "Inside Airspace" will appear. The
nearest airspace page will show "Inside of airspace".
Note that the airspace alerts are based on three-dimensional data (latitude, longitude
and altitude) to avoid nuisance alerts. The alert boundaries for controlled airspace are
also sectorized to provide complete information on any nearby airspace. Once one of the
described conditions exists, the message annunciator will fl ash, alerting you of an airspace
message.
