NOTE:
It is very important to note that not all obstacles are necessarily
charted and therefore may not be contained in the Obstacle Database.
11.4.11 HTAWS Alerts
Alerts are issued when flight conditions meet parameters that are set within
HTAWS software algorithms. HTAWS alerts employ either a CAUTION or a
WARNING alert severity level. 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.
Annunciations are color-coded according to the HTAWS Alert Summary
table. Pop-up terrain alerts will occur if an HTAWS alert is activated while not
on the HTAWS page. There are two options when an alert is displayed:
To acknowledge the pop-up alert and return to the currently viewed
page:
Touch the
Close
key.
To acknowledge the pop-up alert and quickly access the HTAWS Page:
Touch the
ENT
key.
NOTE:
To further capture the attention of the pilot, HTAWS issues aural
(voice) messages that accompany visual annunciations and pop-up alerts.
For a summary of aural messages, see the HTAWS Alert Summary table.
