• Look Ahead Time—Determines the maximum time when an alert annunciation
occurs. For example, if 120 seconds is selected, the G3X 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 G3X 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.
