Nearest Airspace

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.) 

1.   Press the MSG key. The message page appears 

with the alert message. 

2.   Press  MSG  again  to  return  to  the  previous 

display. 

1.   Turn the large right knob to reach the NRST 

function. 

2.  

Turn 

the small right knob to reach the Nearest 
Airspace page. 

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
