nearest Airspace
The Nearest Airspace Page, alerts you to as many as 25 controlled or special
use airspaces near or in your flight 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 ALERT - Airspace entry
in less than 10 minutes
” appears. The Nearest Airspace Page shows the
airspace as “Airspace Ahead.”
• If you are within two nautical miles of an airspace and your current
course will take you inside, the message “
AIRSPACE ALERT - Within
2nm of airspace
” appears. The Nearest Airspace Page shows the air-
space as “Airspace Within 2 NM.”
• If you are within two nautical miles of an airspace and your current
course will take you inside in less than 10 minutes, the message “
AIR-
SPACE ALERT - Airspace within 2nm and entry in less than 10 minutes
”
appears. The Nearest Airspace Page shows the airspace as “Ahead <
2 NM.”
• If you have entered an airspace, the message “
AIRSPACE ALERT
-
Inside Airspace
” appears. The Nearest Airspace Page shows “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 flashes, alerting you of an airspace message (if airspace alert messages
are enabled). See
System-Alerts
to set the Arrival Alert Proximity, Airspace Type,
and Altitude Buffer values.
