Airplane and Systems Description
28 VDC for ADF System operation is supplied through the 3-amp
DME/ADF circuit breaker on AVIONICS BUS. Refer to the Perspective
Integrated Avionics System Pilot's Guide for a general description of
the system and its operating modes. Refer to the Bendix/King ADF
System Pilot's Guide for a detailed discussion of the system.
Bendix/King KN 63 Distance Measuring Equipment (DME)
The KN 63 DME determines airplane distance to a land-based
transponder by sending and receiving pulse pairs - two pulses of fixed
duration and separation. The ground stations are typically collocated
with VORs. The system consists of an antenna installed on the
airplane exterior and the KN 63 receiver which communicates with the
Integrated Avionics System via the secondary Integrated Avionics
Unit.

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 scanning. 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 traditional 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,
