Terrain Alerts - Garmin G3X Pilot's Manual

TERRAIN ALERTS

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.
If the Terrain Page is not displayed, a pop-up alert appears in the lower left corner of
the page. The Range Rings on the pop-up alert are spaced every whole mile/kilometer/
nautical mile. Press the CLR Key to acknowledge the pop-up and/or aural alert.
Terrain and obstacle annunciations appear on the PFD and PFD Page in the upper
left corner of the Attitude Indicator. Arrows are depicted on the terrain and obstacle
annunciations if terrain is outside the Synthetic Vision field of view.
Enabling/Disabling terrain alerts:
From the Terrain Page, press the DISABLE Softkey.
Or:
1) From the Terrain Page, press the MENU Key to access the Page Menu.
2) Turn or move the FMS Joystick to highlight 'Disable Alerts' or 'Enable
Alerts' and press the ENT Key. Disabling terrain alerts is only temporary.
Terrain alerts are automatically enabled when the unit is powered on.
