TERRAIN ALERTS & SETUP
Enabling/Disabling terrain alerts:
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.
Use the Terrain Setup Menu to set levels for terrain alerts as well as obstacles
in or near your flight path.
Caution Elevation• —The G300 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 G300 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 G300
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.
Setting up the Terrain Page:
1)
On the Terrain Page, press MENU to access the Page Menu.
2)
Turn or move the FMS Joystick to highlight ‘Set Up Terrain’ and press
the ENT Key.
3)
Move the FMS Joystick to highlight the desired field.
4)
Turn the FMS Joystick to make changes to the highlighted field.
