GENERAL NOTES ON AIRSPACE ALERTS
Once an airspace alert has been selected, associated information concerning the specific airspace is
provided. The information includes Airspace Name, Status, and Time to Entry. The status and time to entry
(if applicable) are based on the following conditions:
• If the projected course will take the aircraft inside an airspace within the next ten minutes, the status field
shows the airspace as ‘Ahead’.
• If the aircraft is within two nautical miles of an airspace and the current course will take the aircraft inside,
the status field shows the airspace as ‘Ahead < 2 nm’.
• If the aircraft is within two nautical miles of an airspace and the current course will not take the aircraft
inside, the status field shows ‘Within 2 nm’.
• If the aircraft has entered an airspace, the status field shows ‘Inside’.
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 sectored to provide complete information on any
nearby airspace. Once the described conditions exists, the status and time of entry is shown if the airspace alert
messages are enabled on the System Setup Page (Auxiliary Page Group; see the System Overview Section).
At most three airspace alerts are displayed at any given time. The user can change the airspace alerts that
are currently visible. For each airspace alert the name of the airspace, the proximity status (Inside, Ahead <
2nm, Ahead, Within 2nm), and the time until the current path of the aircraft will intercept the airspace (only
when the airspace is Ahead, or Ahead < 2nm, otherwise “__:__:__” is used) is displayed. If there are more
than three airspace alerts they are displayed in a scrollable list box with only three visible at one time.
