Hazard Avoidance
• Look Ahead Time—Determines the maximum time when an alert annunciation
occurs. For example, if 120 seconds is selected, the aera 795/796 provides an
alert up to 120 seconds before you reach 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 795/796
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.
