Introduction 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-discharge displays, the CNI 5000 is easy to read from virtually any viewing angle in the cockpit.
System Components ı USE CHAN Dual 760 or optional 2280 frequency COMM tranceivers, each with nine pilot-programable channels. PULL 25K CHAN STBY COMM 1 OFF PULL TEST FAN USE STBY PULL 25K CHAN COMM 2 CHAN OFF Fan-Fail Annunciators provide warning of internal cooling fan failure. PULL TEST FAN USE STBY Dual NAV Receivers that will tune 200 VOR/LOC channels and 40 Glideslope channels.
Operating Instructions - COMM Standard COMM (25 kHz Frequency Spacing) "USE" window shows active frequency Photocell for automatic dimmimg USE "STBY" window shows stored or newly-entered standby frequencies "CHAN" window shows selected channel number STBY CHAN "T" indicates mike button is depressed for transmission Frequency transfer "flip-flop" button PULL 25K CHAN COMM 1 OFF Channel button PULL TEST Frequency selector knobs ON/OFF/Volume control switch. Pull out for manual squelch override.
The Frequency Mode (Normal Operation). Standard COMM 1a. Select a new frequency in the “STBY” window, using the frequency selection knobs. The larger knob controls changes in increments of 1MHz. The smaller knob controls changes in increments of 50kHz when pushed in, and 25kHz when pulled out. Proceed to Step 2. USE STBY CHAN OFF T USE STBY T STBY OFF PULL TEST Optional COMM 1b. Select a new frequency in the “STBY” window, using the frequency selection knobs.
Channel Mode. The Channel Mode is used to recall preset frequencies stored in memory. Direct Tune Mode. The Direct Tune Mode is entered by pressing and holding the transfer button for longer than two seconds. The “STBY” frequency will disappear and the frequency in the active window can be changed with the frequency selection knobs. 1. To enter the Channel Mode, momentarily push the channel (CHAN) button while in the Frequency Mode.
Modes, “dA 1” through “dA 3.” Press the frequency transfer button to exit the Display Adjust Mode. light conditions are less than direct sunlight, such as in a dark cockpit. dA 2 values range from 0-64, with 0 being dimmest and 64 being brightest; the normal dA 2 setting is 20. dA 3 values range from 0 to 255, with 0 being the dimmest and 255 being the brightest. The adjustment varies the amount of ambient light required for the display to reach its full dim and bright levels.
Operating Instructions - NAV The CNI 5000 has two identical NAV receivers. The following operating instructions apply to NAV 1 and NAV 2. in 50kHz steps. At either band edge of the 108.00 to 117.95 MHz frequency spectrum, an off-scale rotation will wrap the display around to the other frequency band-edge (i.e., 117.95 advances to 108.95 with the MHz knob rotation, or 117.00 with the kHz knob rotation). Remote DME and glideslope receivers are also controlled by these selector knobs. Power Up.
Operating Instructions - ADF ANT/ADF mode annunciation Photocell for automatic dimming Flight Timer and Elapsed Timer mode annunciation STANDBY frequency annunciation "USE" window shows active STANDBY frequency, frequency FLIGHT TIME or BFO mode ELAPSED TIME annunciation USE STBY/TIMER ADF ADF Select ANT mode (out position) Select ADF mode (in position) BFO FRQ Select BFO Frequency transfer "flip-flop" button SET ET/FLT VOL RST OFF Select FLIGHT TIMER or ELAPSED TIMER Set and Reset ELAPSED TI
ANT (NOTE: pressing the SET/RST button will reset the elapsed timer whether it is being displayed or not). FLT ET USE STBY/TIMER ADF ADF BFO FRQ ET/FLT SET VOL RST OFF Outside the United States some stations are unmodulated and use an interrupted carrier for identification purposes. The BFO mode, activated and annunciated when the “BFO” button is depressed, permits the carrier wave and the associated morse code identifier broadcast on the carrier wave to be heard.
quency will overlap. For this reason, it is always wise to make positive identification of the station being tuned, by switching the function selector to ANT and listening for the station call letters. these times. If possible, tune to the most powerful station at the lowest frequency. If this is not possible, take the average of pointer oscillations to determine relative station bearing. Electrical Storms.
Operating Instructions - XPDR Ident button Photocell for automatic dimming ALT/ON/GND/SBY mode annunciation Reply indicator Transponder code readout TST GND ON SBY ALT OFF IDT FL XPDR 1 PUSH VFR Flight Level— indicates altitude. Display is in 100 ft. increments and is referenced to 29.92 in. Hg. Transponder Code selector knobs The CNI 5000 has two identical Modes S Transponders. A special international version of the CNI 5000 is available with standard ATCRBS transponders.
FUNCTION SELECTOR The Function Selector on the right side of the transponder portion of the CNI 5000 is used to select the different modes of operation of the Mode S transponder. The different modes are as follows: annunciated on the display in this mode. The altitude display is disabled. TST- (Test) The unit will illuminate all segments of the display for at least four seconds. A series of tests are performed internally that check the integrity of the Mode S system. OFF- The unit is not energized.
then be selected to “ON” or “ALT” on the ground, but will continue to annunciate “GND” and only accept Mode S interrogations. Once the aircraft is airborne and the strut switch relaxes, the unit automatically annunciates the selected mode and operates accordingly. This feature eliminates the possibility of taking off and forgetting to activate the Mode A/C capability of the transponder.
