BendixKing CNI 5000 - Manual (Page 3)

The CNI 5000 is a compact and light
weight Integrated Avionics System
designed especially for the sophisticated
environment of today’s cockpit.
The integrated design of the CNI 5000
provides the pilot with full-featured
COMM/NAV/IDENT capability in a single
unit. With large, self-dimming gas-dis-
charge displays, the CNI 5000 is easy to
read from virtually any viewing angle in the
cockpit. COMMs, NAVs, and ADF feature
“flip-flop” frequency preselection which
gives the pilot the ability to set up en route
or approach frequency changeovers well in
advance of the actual transition point or
ATC handoff sequence for true “stay-
ahead” flight management.
Innovative non-volatile memory circuits
hold all displayed frequencies in storage—
through aircraft shutdowns or momentary
power interruptions—without the need for
battery power of any kind.
Seven modules make up the CNI 5000.
These include two COMMs, two NAVs, an
ADF and two Transponders (XPDR). The
modular architecture of the CNI 5000
makes it possible to replace a COMM,
NAV, ADF or XPDR portion of the system
with out complete removal of the CNI unit.
Each STANDARD COMM is capable of
tuning 760 frequencies from 118.000MHz
to 136.975MHz with frequency spacing of
25kHz. An optional COMM package is
available with each COMM capable of tun-
ing 2280 frequencies from 118.0000 MHz
to 136.9916 MHz with frequency spacing of
8.33 kHz. An audio-leveling feature auto-
matically amplifies weak audio signals and
mutes signals that are too strong. A safety
feature of the CNI 5000 COMMs is the
stuck-microphone indicator. If the mic is
keyed for more than two minutes, the dis-
play will begin to flash, and the unit will
cease transmitting. This alerts you to the
problem while it prevents you from inadver-
tently jamming a frequency and making it
unusable to other pilots.
The versatile NAVs will tune all 200
VOR/LOC frequencies in addition to the 40
glideslope frequencies. Output is also pro-
vided for automatic changing of the remote
DME system.
The ADF receiver provides accurate
bearing to stations in the 200kHz to
1799kHz frequency range. Complete ADF,
ANT and BFO tuning modes are provided,
along with audio output for station identifi-
cation and monitoring of AM broadcasts.
It’s advanced “coherent detection”
design rejects unwanted interference,
achieves significantly greater range and
has less susceptibility to engine noise, sta-
tic, and atmospheric interference.
The standard CNI 5000 offers dual
Mode S transponders. A version of the
CNI 5000 is also available with dual
ATCRBS Transponders for special interna-
tional applications.
The new Mode S (Mode Select)
transponders are designed to provide ATC
with improved aircraft surveillance and
reporting accuracy, and reduce interfer-
ence in identity and altitude reporting.
These improvements are made possible be
cause each aircraft is assigned a unique
address code. By using this code in the
form of a discrete addressing system, a
Mode S ground installation is able to
selectively interrogate a specific aircraft,
even in high-density situations. This signifi-
cant improves the ability of ATC to monitor
and direct your aircraft—along with those
around it. Offering full Mode A and Mode C
compatibility, Mode S meets all current
ATCRBS technical requirements.
The CNI 5000 Mode S and ATCRBS
Transponders feature digital display of
encoded altitude and ATC code, push but-
ton selection of VFR code, remote-ident
switch capability, and a XPDR 1/2 Select
Switch for quick selection of either
transponder.
The CNI 5000 offers state-of-the-art
technology and pilot-preferred features to
significantly increase cockpit efficiency and
decrease pilot workload.
This Pilots Guide covers basic operat-
ing procedures of the CNI 5000 by function,
i.e. COMM, NAV, ADF and XPDR. Simple
operation and the ease with which you can
learn to use it serve to enhance it’s perfor-
mance and capabilities.
