SECTION 11 – ADDITIONAL
FEATURES
Terrain-SVS and TAWS Alerting
Terrain alerting on the synthetic terrain display is
triggered by Forward-looking Terrain Avoidance (FLTA)
alerts, and corresponds to the red and yellow X symbols
on the Inset Map and MFD map displays. For more
detailed information regarding Terrain-SVS and TAWS,
refer to the Hazard Avoidance Section.
In some instances, a terrain or obstacle alert may be
issued with no conflict shading displayed on the synthetic
terrain. In these cases, the conflict is outside the SVS field
of view to the left or right of the aircraft.

Obstacles are represented on the synthetic terrain
display by standard two-dimensional tower symbols found
on the Inset map and MFD maps and charts. Obstacle
symbols appear in the perspective view with relative height
above terrain and distance from the aircraft. Unlike the
Inset map and MFD moving map display, obstacles on the
synthetic terrain display do not change colors to warn of
potential conflict with the aircraft' s flight path until the
obstacle is associated with an actual FLTA alert. Obstacles
greater than 1000 feet below the aircraft altitude are not
shown. Obstacles are shown behind the airspeed and
altitude displays.
