Nearest Airspace Page

The last page in the NRST group, the nearest air-
space page, will alert you to as many as nine controlled
or special use airspaces near or in your flight path.
Alerts are provided according to the following condi-
tions:
• If your projected course will take you inside an
airspace within the next ten minutes, the alert
message "Airspace ahead -- less than 10 min-
utes" 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 nearest airspace page will show the
airspace as "Ahead < 2nm".
• If you have entered an airspace, the message
"Inside Airspace" will appear. The nearest air-
space page will show "Inside of airspace".
