Note that the airspace alerts are based on 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. Once one of the 
described conditions exists, the message annunciator 
will flash, alerting you of an airspace message. 

1.   When  the  message  annunciator  above  the 

MSG key flashes, press MSG. 

2.   Press  MSG  again  to  return  to  the  previous 

page. 

Once you have been provided an airspace alert 

message, detailed information concerning the specific 
airspace is provided on the nearest airspace page. The 
nearest airspace page displays the airspace name, status 
(“Ahead”, “Ahead < 2nm”, etc. as described on the 
previous page), and a time to entry (if applicable). By 
selecting any airspace name listed on the nearest air-

space page, additional details will be provided—includ-
ing controlling agency, communication frequencies 
and floor/ceiling limits. 

1.   Select the nearest airspace page. 

2.   Press  the  small  right  knob  to  activate  the 

cursor. 

3.   Turn the large right knob to scroll through 

the list, highlighting the desired airspace. 

4.   Press ENT to display the airspace page for the 

selected nearby airspace.

that “Done?”  is  highlighted  by  the  flashing 
cursor and press ENT.
