10.8.4 TAWS-A Page
The TAWS-A page shows terrain, obstacle, and threat location data in relation
to the aircraft’s current altitude, without clutter from the basemap. Aviation
data (airports, VORs, and other NAVAIDs) can be displayed for reference. If
an obstacle and the projected flight path of the aircraft intersect, the display
automatically zooms in to the closest potential point of impact on the TAWS-A
page.
Aircraft orientation on this map is always heading up unless there is no valid
heading. Two views are available relative to the position of the aircraft: the 360°
default display and the radar-like ARC (120°) display. Map range is adjustable
with the
In
and
Out
keys from 1 to 200 NM, as indicated by the map range rings
(or arcs).
