Terrain
Grouped obstacles are shown with an asterisk (as shown in the Windmill in
Group example above). The color of the asterisks is tied to the relative altitude
of the highest obstacle in the group, not other obstacles within that group.
Obstacles are grouped when they would otherwise overlap.
10.6.5 TAWS-B Page
TAWS information is displayed on the Map and Terrain pages. The TAWS
page is specialized to show terrain, obstacle, and threat location data in relation
to the aircraft’s current altitude, without clutter from the basemap. Flight plan
information (airports, VORs, and other NAVAIDs) included in the flight plan are
displayed for reference. If an obstacle and the projected flight path of the aircraft
intersect, the display automatically zooms in to the closest threat location on the
TAWS page.
Aircraft orientation on this map is always heading up unless there is no valid
heading. If orientation is not heading up, it will be track up. 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).
