Section 3: TAWS Alerts
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. Annunciations appear in a dedicated field in the lower
left corner of the display (Figure 3-1). Annunciations are color-coded according to Table 3-2 (page 63).
Pop-up terrain alerts can also appear during an alert, but only when the TAWS Page is not displayed.
There are two options when an alert is displayed:
To acknowledge the pop-up alert and return to the currently viewed page:
1. Press the CLR button.
To acknowledge the pop-up alert and quickly access the TAWS Page:
1. Press the ENT button.
To further capture the attention of the pilot, TAWS issues aural (voice) messages that accompany visual
annunciations and pop-up alerts. Some aural messages are configurable during installation of the
system. For a summary of aural messages, see Table 3-2.
