Use the Terrain Setup Menu to set levels for terrain alerts as well as obstacles in

• Caution Elevation—The aera 760 will provide an alert if the terrain or obstacle is
within the default Caution Elevation or user-defined Caution Elevation
• Look Ahead Time—Determines the maximum time when an alert annunciation
occurs. For example, if 120 seconds is selected, the aera 760 provides an alert up
to 120 seconds before reaching the terrain or obstacle
• Alert Sensitivity—The three Alert Sensitivity settings (Terrain, Obstacle, and Descent
Rate) determine what level of alerts are annunciated. The aera 760 defaults to
‘High’ sensitivity, which annunciates all red and yellow alerts at the time set in
Look Ahead Time. ‘Medium’ sensitivity annunciates all of the red and the highest
priority of yellow alerts. ‘Low’ only annunciates red alerts. ‘Off’ disables the alert.

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.
