12.3 TERRAIN ALERTS

TERRAIN Alerts are issued when flight conditions

meet parameters that are set within TERRAIN software
algorithms. TERRAIN alerts typically employ either an
ADVISORY or a CAUTION alert severity level, or both.

When an alert is issued, visual annunciations are

displayed.

Annunciations appear in a dedicated field in the lower

left corner of the display (Figure 12-2). Annunciations
are color-coded according to Table 12-2.

NOTE: TERRAIN Advisory Alerts are displayed
as constant black text on a yellow background;
TERRAIN Caution Alerts are displayed as flashing
black text on a yellow background.

Pop-up terrain alerts (Figures 12-3 & 12-4) can also

appear during an alert, but only when the TERRAIN Page
is not displayed.

There are two options when an alert is displayed:

• Press the CLR Key. This acknowledges the

pop-up alert and returns to the currently
viewed page.

• Press the ENT Key. This acknowledges the

pop-up alert and accesses the TERRAIN Page.
