tion is supplied through the 3-amp DME/ADF circuit breaker on
AVIONICS. Refer to the Pers Integrated Avionics System Pilot’s
Guide for a general description of the system and its operating modes.
Refer to the Bendix/King DME System Pilot’s Guide for a detailed discus-
sion of the system.
Synthetic Vision System
The Synthetic Vision System (SVS) is intended to provide the pilot with
enhanced situational awareness by placing a three dimensional depiction of
terrain, obstacles, traffic and the desired flight path on the PFD so that
proximity and location is more easily understood during instrument scan-
ning. The SVS database is created from a digital elevation model with a 9
arc-sec (approx. 885 ft (270m)) horizontal resolution.
The synthetic vision system is not intended to be used independently of
traditional attitude instrumentation. Consequently, SVS is disabled when
traditional attitude instrumentation is not available. Otherwise, the tradi-
tional attitude instrumentation will always be visible in the foreground with
SVS features in the background. The PFD with SVS installed includes:
•
Perspective depiction of surrounding terrain,
•
Zero pitch line,
•
Perspective depiction of runways,
•
Perspective depiction of large bodies of water,
•
Perspective depiction of obstacles,
•
Flight path marker,
•
Terrain warning system, and
•
Field of view depiction on the MFD Navigation Page.
Refer to the Pers Integrated Avionics System Pilot’s Guide for a
complete description of the system, its operating modes, and additional
detailed operating procedures.
Max Viz Enhanced Vision System
The Enhanced Vision System is an electro-optical system that uses a
Long-Wave Infrared (IR) camera. Infrared is particularly effective at night,
smoke, haze, and smog in addition to a broad spectrum of rain, snow, and
radiation-type fog. However, penetration is limited during certain environ-
mental conditions associated with heavy rain, heavy snow, coastal fog and
most cloud formations. Therefore, the EVS is not intended for all atmo-
spheric conditions and may only be used for acquisition of objects normally
viewed through the cockpit windows. EVS is an aid to visual acquisitions of:
•
Ground vehicles and other ground-based equipment/obstacles,
•
Aircraft on taxi-ways and runways,
•
Other traffic during takeoff, approach, and landing,
•
Runway and taxi lights, and
