SECTION 11: ADDITIONAL
FEATURES
11.1 SYNTHETIC VISION SYSTEM (SVS)
(OPTIONAL)
WARNING: Use appropriate primary systems
for navigation, and for terrain, obstacle, and
traffic avoidance. SVS is intended as an aid to
situational awareness only and may not provide
either the accuracy or reliability upon which to
solely base decisions and/or plan maneuvers to
avoid terrain, obstacles, or traffic.
The optional Synthetic Vision System depicts a forward-
looking attitude display of the topography immediately in
front of the aircraft. The field of view is 30 degrees to the
left and 35 degrees to the right. The depicted imagery
is derived from the aircraft attitude, heading, GPS three-
dimensional position, and a nine arc-second database of
terrain, obstacles, and other relevant features. Loss of any
of the required data, including temporary loss of the GPS
signal, will cause SVS to be disabled until the required data
is restored.
The SVS terrain display shows land contours (colors are
consistent with those of the topographical map display),
large water features, towers, and other obstacles over 200’
AGL that are included in the obstacle database. Cultural
features on the ground such as roads, highways, railroad
tracks, cities, and state boundaries are not displayed even
if those features are found on the MFD map. The terrain
display also includes a north–south east–west grid with
lines oriented with true north and spaced at one arc-minute
intervals to assist in orientation relative to the terrain.
The optional Terrain Awareness and Warning System
(TAWS) or standard Terrain-SVS is integrated within SVS to
provide visual and auditory alerts to indicate the presence
of terrain and obstacle threats relevant to the projected
flight path. Terrain alerts are displayed in red and yellow
shading on the PFD.
The terrain display is intended for situational awareness
only. It may not provide the accuracy or fidelity on which
to base decisions and plan maneuvers to avoid terrain or
obstacles. Navigation must not be predicated solely upon
the use of the Terrain–SVS or TAWS terrain or obstacle
data displayed by the SVS.

SVS Operation
SVS is activated from the PFD using the softkeys
located along the bottom edge of the display. Pressing the
softkeys turns the related function on or off. When SVS
is enabled, the pitch ladder increments are reduced to 10
degrees up and 7.5 degrees down.
SVS functions are displayed on three levels of softkeys.
The PFD Softkey leads into the PFD function Softkeys,
including synthetic vision. Pressing the SYN VIS Softkey
displays the SVS feature softkeys. The softkeys are labeled
PATHWAY, SYN TERR, HRZN HDG, and APTSIGNS.
The BACK Softkey returns to the previous level of
softkeys. Synthetic Terrain must be active before any
other SVS feature may be activated.
