Synthetic Vision
Synthetic Vision (SVN) gives users a forward looking perspective of the terrain ahead. This includes
mountains, rivers/waterways, obstacles and runways. The Synthetic Vision database requires a Map Data
card be installed in the unit. While the mapping option isn't necessary for SVN to work, the two share the same
databases on the Map Data card. Grid lines are displayed on the ground of SVN. They are 1 arc minute lines,
meaning at the equator they are 1nm by 1nm squares. As the aircraft is positioned farther North or South of
the equator, the East/West lines of the grid are drawn closer together.
Note: Having synthetic vision changes the way the attitude indicator behaves; users will want to spend time flying with
SVN in visual conditions before attempting to fly in IMC.
The biggest change new SVN users will notice is the lack of a definite horizon like a standard attitude
indicator. Attitude indicators traditionally represent level flight when the miniature airplane is on the intersection
of the blue and brown shading. Since in real life the aircraft is not level with the horizon in level flight, a
synthetic zero pitch line has to be displayed over the primary flight display. This zero pitch line is shown as at
thin white line extending from the left side of the PFD page all the way to the far right side of the PFD page.
SVN will show a maximum distance of 3nm
ahead of the aircraft when on the ground and
achieves the maximum possible distance of
50nm when at 1,800AGL and above.
Synthetic Vision Settings
Enable/Disable - Press EFIS -> SETTINGS -> MORE -> ON/OFF
Instrument Calibration: 35: Synthetic Vision
1. Synthetic Vision ON/OFF - Enables/Disables
SVT (if the software key is installed)
2. Altitude Source - (AUTO, GPS ONLY, BARO
ONLY) - Selects the altitude source for SVN
Terrain Awareness and Warning System
(TAWS)
TAWS is a system designed to keep the pilot
alert of altitudes that could result in Controlled
Flight into Terrain (CFIT). Terrain is shaded in
yellow or red based on the altitude of the aircraft
and the altitude of the terrain below. When the
distance between the aircraft and terrain below
becomes close enough to present a conflict, the
terrain is colored yellow or red. TAWS is drawn in
a 6nm square around the aircraft.
When enabled, TAWS arms automatically when
climbing through 1,200ft AGL. This is to prevent false warnings in the traffic pattern. TAWS is disabled when
the aircraft slows to the shutoff speed set in Instrument Calibration under
TAWS Terrain Colors:
RED - Aircraft is within 100ft AGL of the terrain
YELLOW - Aircraft is between 1,000ft AGL and 100ft AGL of the terrain.
