Terrain Alerts - Garmin G300 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.
AURAL ALERTS
• "Five Hundred"—when the aircraft descends through 500 feet above the
destination airport.
The following aural terrain alerts are issued when flight conditions meet
