TAWS-B ALERTS
Alerts are issued when flight conditions meet parameters that are set within TAWS-B software algorithms.
TAWS-B alerts typically employ a CAUTION or a WARNING alert severity level, or both. When an alert is
issued, the system displays visual annunciations with voice alerts. Table 6-9 shows TAWS-B alert types with
corresponding annunciations and voice alerts.
When an alert occurs, the system displays annunciations on the PFDs and MFD. The TAWS-B Alert
Annunciation is shown to the upper left of the Altimeter on the PFDs and below the Terrain Legend on the
MFD. If the TAWS-B Page is not displayed at the time of the alert, a pop-up alert appears on the MFD. When
a pop-up alert occurs, do one of the following:
• Press the CLR Key (removes the pop-up alert), or
• Press the ENT Key (accesses the TAWS-B Page)
