11.3 TAWS ALERTS
TAWS Alerts are issued when flight conditions meet
parameters that are set within TAWS software algorithms.
TAWS alerts typically employ either a CAUTION or a
WARNING alert severity level, or both.
When an alert is issued, visual annunciations are
displayed. Aural alerts are simultaneously issued.
Annunciations appear in a dedicated field in the lower
left corner of the display (Figure 11-2). Annunciations
are color-coded according to Table 11-2.

Pop-up terrain alerts (Figures 11-3 & 11-4) can also
appear during an alert, but only when the TAWS 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 TAWS Page.
NOTE: To further capture the attention of the
pilot, TAWS issues aural (voice) messages that
accompany visual annunciations and pop-up
alerts.

installation-dependent.

constant black text on a yellow background;
TAWS Warning Alerts are displayed as constant
white text on a red background.
