5.4 TERRAIN
WARNING: Do not use Terrain information for primary terrain avoidance. Terrain
information is intended only to enhance situational awareness.
NOTE:
Terrain data is not displayed when the aircraft is outside of the installed terrain
database coverage area.
NOTE: Terrain and obstacle alerting is not available north of 89º North latitude
and south of 89º South latitude. This is due to limitations present within the Terrain
database and the system’s ability to process the data representing the affected areas.
NOTE: No terrain or obstacle alerting occurs if Terrain Proximity is the only terrain
function configured.
The following terrain configurations are allowed:
