Terrain Alerts
TERRAIN Failure Alert
The TERRAIN system continually monitors
several system-critical items, such as database validity,
hardware status, and GPS status. Should the system
detect a failure, a message is annunciated “TERRAIN
has failed”.
“TERRAIN has failed” message
“TERRAIN Not Available” Alert
The TERRAIN system requires a 3D GPS
navigation solution along with specific vertical
accuracy minimums. Should the navigation solution
become degraded, if the terrain/obstacle database is
not available, or if the aircraft is out of the database
coverage area, the annunciation “TERRAIN NOT
AVAILABLE” is displayed on the TERRAIN Page.
