Hazard Avoidance

TERRAIN SETTINGS

Use the terrain settings to set levels for terrain alerts as well as obstacles in or
near your flight path.
• Caution Elevation—The G3X 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 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.
