EVOLUTION SYNTHETIC VISION (OPTIONAL)
N O T E
Navigation or maneuvering based solely on the EFD1000 or MFD500 Synthetic Vision
background display and associated Terrain Warning System (TWS) is not authorized. The
Pilot in command has the responsibility to use accepted visual procedures to avoid terrain
and other obstacles.
N O T E
Flight with an expired database is not recommended. An expired database does not
prevent terrain or other Synthetic Vision features from being displayed.
N O T E
No Sonalert installed. Only on-screen Alert Annunciations, FPM Alert Colors, and Terrain
Coloring are configured
The EFD1000/500 Evolution Synthetic Vision system provides a computer-derived view of the
nearby terrain, obstacles and airports. The Flight Path Marker graphically presents the aircraft
vertical speed and the GPS track converted to an angular direction. The Terrain Warning System
(TWS) uses the Flight Path Marker to present an estimated time-to-collision function for terrain and
obstacles combined with a terrain proximity view that colorizes nearby terrain based on the relative
aircraft height. Unless inhibited by the pilot, TWS even operates when SV is turned off.
The EFD100/500 display of Synthetic Vision information is advisory only. The pilot is responsible
for terrain and obstacle avoidance by visual means. At system start up the pilot must acknowledge
this operational limitation by pressing either MODE/SYNC knob.
Evolution Synthetic Vision is a computer-generated image of the external scene topography from
the perspective of the flight deck, derived from aircraft altitude, high-precision navigation solution,
and database of terrain, obstacles and cultural features, such as runways. Evolution Synthetic
Vision creates an image relative to terrain, obstacles and airports within the limits of the navigation
source, altimetry and databases. Evolution Synthetic Vision provides situation awareness, but no
operational credit. The intended function is flight crew awareness of the external scene topography.
The Aspen Evolution Synthetic Vision System uses 9 arc-second resolution data enhanced with
3 arcsecond data to provide better depiction of the terrain. The depiction of terrain is most like the
outside view in the narrow FOV1 view, and a more expansive view of the horizon is available in FOV2.
The terrain depicted in FOV2 is closer than it appears.
The intended function of the Flight Path Marker is to display the current vertical and lateral path of
the aircraft based on two parameters, barometric vertical speed and GPS track. These parameters
lag during dynamic maneuvers. Therefore the Flight Path Marker should only be used during steady
state, nonaccelerated flight. It is not intended to provide accurate information during turns,
transitions to climb or descent or acrobatics.
The intended function of the Terrain Warning System associated with the Evolution Synthetic Vision
application is to provide warnings when the system predicts a collision with the terrain or an
obstacle. The Flight Path Marker is an integral part of this system and changes in shape and color
