Nearest Airspace Page

The last page in the NRST group, the nearest
airspace page, provides information for up to nine
controlled or special-use airspaces near or in your
flight path. Airspace information appears on this page
based upon the same criteria used for airspace alert
messages. Nearby airspace information and airspace
alert messages are provided according to the following
conditions:
• If your projected course will take you inside an
airspace within the next ten minutes, the mes-
sage "Airspace ahead -- less than 10 minutes" will
appear.
• 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.
• 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.
• If you have entered an airspace, the message
"Inside Airspace" will appear.
By default, airspace alert messages are turned off.
When turned on, the message (MSG) annunciator
located directly above the MSG key will flash to alert
you to the airspace message. (See Section 9 Aux Pages
- Setup 1 for information on enabling airspace alert
messages.)

Note that the airspace alerts are based upon three-
dimensional data (latitude, longitude and altitude) to
avoid nuisance alerts. The alert boundaries for con-
trolled airspace are also sectorized to provide complete
information on any nearby airspace. Additional infor-
mation about a nearby airspace—such as controlling
agency, frequency and floor/ceiling limits—is available
from the nearest airspace page.
