Terrain, Obstacle, and Descent Rate Alerts are issued when flight conditions meet
parameters that are set within the software algorithms. Terrain alerts typically employ
a CAUTION or a WARNING alert severity level, or both. When an alert is issued, visual
annunciations are displayed and aural alerts are simultaneously issued. When the
aircraft descends through 500 feet above the destination airport an audible “Five
Hundred” altitude reminder occurs.
The Terrain Alert Annunciation is shown to the lower left corner of the screen. If the
Terrain Map is not displayed, a pop-up alert appears. The Range Rings on the pop-
up alert are spaced every whole mile/kilometer/nautical mile. Touch the Terrain Alert
Annunciation to acknowledge the pop-up and/or aural alert.
