CAUTION: Obstacles 200 feet and higher are in-
cluded in the Obstacle Database. It is very impor-
tant to note that not all obstacles are necessarily
charted and therefore may not be contained in
the Obstacle Database.
Navigation Database
It is therefore important to also have the latest
Navigation Database installed to ensure correct Terrain
alerting.

TERRAIN Alerts

TERRAIN alerts are issued when flight conditions
meet parameters that are set within the TERRAIN system
software algorithms. When an alert is issued, visual
annunciations are displayed. Annunciations appear in a
dedicated field in the lower left corner of the display.
