FLITELINE AVIONICS SYSTEM PILOT’S GUIDE Page 4 Publication No. 150-047012 Dec 2005 Rev. D Introduction The FliteLine™ Avionics Systems represent the next generation of Chelton avionics. The FliteLine Control Display units are subsystems of the Chelton Avionics FliteLine Systems. The FliteLine NAV/COM/ADF/ATC Control Displays are one of several methods of controlling the Chelton Avionics FliteLine remote-mounted avionics systems. The FliteLine name builds from the reputation and heritage that Wulfsberg™ has enjoyed with the Flitecomm™ and Flitefone® products. The new FliteLine products are the latest line of Chelton's remote-mounted avionics. In addition to the Control Display units, the individual systems within the FliteLine product line include: FliteCOMM™, FliteNAV™, FliteXPDR™, and FliteDME™
FLITELINE AVIONICS SYSTEM PILOT’S GUIDE Publication No. 150-047012 Page 5 Rev. D Dec 2005 FliteLine VHF Communication System (FliteCOMM) General Description CVC-151 The FliteLine CVC-151 is an all digital DSP VHF Comm Transceiver, built and designed to ARINC Air Transport specifications. The Transceiver is designed to meet the latest ATC environment, all future CNS ATN requirements, and has provisions for VDL Mode 2 and VDL Mode 3. The CVC-151 features a 20 watt solid-state transmitter, is compliant with 25 kHz or 8.33 kHz spacing and the architecture is standard ARINC 429 which supports interface to FMS systems and the Chelton RMS 555 Radio Management System. The CVC-151 Transceiver is interchangeable with current Series III VHF Comm Transceivers using a special mounting tray adapter.

The CVC-152 is a direct replacement for the Chelton CD-402B and CD-402C Control Display Units. The CVC-152 Control Display Unit provides a simultaneous readout of two frequencies: The active frequency in the upper display and, immediately below it, the standby frequency. Frequency switching is accomplished by simply pressing a frequency transfer button. The Transmit Annunciator (Tx) appears in the display when RF is present at the output of the transceiver, providing positive proof-of-operation. When the CVC-152 Control Display Unit is turned on, a diagnosis of all critical circuits begins, and continues until the System is turned off. If a fault is detected at any time, a FAIL annunciation appears in the display. The CVC-152 Control Display Unit has a nonvolatile memory which allows it to remember the last frequencies displayed, indefinitely, even when power is removed. This feature prevents momentary power interrupts from affecting the system, and allows the last frequencies used to appear immediately when the System is turned on.
FLITELINE AVIONICS SYSTEM PILOT’S GUIDE Page 6 Publication No. 150-047012 Dec 2005 Rev. D The CVC-152 Communication Control Display Unit is designed to interface with Chelton FliteLine Communications Radios (CVC-151), Chelton Series III Communications Radios (VC-401B and VC-401C in the VCS 40 Systems), and Collins Communication Radios with the ARINC 410 (2x5) Interfaces.

The desired frequency is now active and may be used immediately. 4. Use the VOLUME CONTROL to adjust volume if a station is broadcasting. 5. To set a new standby frequency, rotate the appropriate FREQUENCY KNOB until the desired frequency is displayed in the lower line of the display. NOTE: To tune the active frequency only (without first tuning the standby and then "flipping" the frequencies), press and hold the FREQUENCY TRANSFER button for two seconds, then release it. This removes the standby frequency from the display. The FREQUENCY KNOBS may now be used to change the active frequency. Press and hold the FREQUENCY TRANSFER button for two seconds again to restore the standby frequency to the display, if desired.
FLITELINE AVIONICS SYSTEM PILOT’S GUIDE Publication No. 150-047012 Page 15 Rev. D Dec 2005 CVC-152 Notes 1. The FREQUENCY SELECTOR knobs tune the radio transceiver directly. The display shows the frequencies to which the radio transceiver is actually tuned. In addition to the CVC-152, the Chelton Series III transceivers may also be tuned by an ARINC 429 digital bus. In addition to the CVC-152, the Chelton FliteLine transceivers may be tuned by either ARINC 429 digital bus or Controller Area Network (CAN) Bus. 2. Display intensity and panel lighting are controlled by external dimmer controls. 3. Pressing and holding the FREQUENCY TRANSFER button for at least 7 seconds before releasing it sets the COM active frequency to 121.50 MHz and puts the unit into the active tuning mode. This is true even if segments of the display are faulty or a lighting failure occurs. From this known reference point, any other frequency may be set by counting detents of the FREQUENCY SELECTOR knobs as they are rotated. Each clockwise detent of the outer knob is one Megahertz difference. Each clockwise detent of the inner knob is 25kHz or 8.33 kHz difference. 4. The FREQUENCY SELECTOR knobs rotate continuously through all detents without end stops. After rotating the outer knob clockwise to the highest number, the next detent will be the lowest number (118 MHz). 5. Pressing and holding the left pushbutton (PWR) for more than 1 second will trigger the system to shutdown. A warning screen will display a countdown. Releasing the PWR button before the count has expired will return the unit to the display screen active prior to initiating the shutdown. Should the system become unresponsive, a hardware failsafe shutdown can be initiated. Under this circumstance, press and hold the PWR button for 12-15 seconds. There is no indication other than actual system shutdown and an audible click. 6. The system that is in the off condition may be turned on by simply pressing the PWR button momentarily. 7. Systems configured for ARINC 410 (2x5) Digital Interface will only support fixed channel operation. There is no TX indicator on a system configured for ARINC 410 interface.

FLITELINE AVIONICS SYSTEM PILOT’S GUIDE Page 18 Publication No. 150-047012 Dec 2005 Rev. D General Description CVN-252 The Chelton CVN-252 VHF Navigation Control Display is designed to control VHF navigation receiving systems that combine VOR/LOC, glideslope, and marker beacon reception. The CVN-252 is a direct replacement for the Chelton CD-412B Control Display Unit. The CVN-252 Control Display can digitally display BEARING TO or RADIAL FROM any selected VOR station. When an ILS frequency is selected by the Series III or FliteLine Navigation radio, the letters LOC appear below the frequency on the display when RAD or BRG are selected. The CVC-252 Control Display incorporates microprocessor technology to achieve performance, reliability, accuracy, and features not possible in previous systems. These include advanced filtering techniques, full-time self-diagnostics, non-volatile frequency memory. Special filtering circuits virtually eliminate noise, including rotor modulation noise in helicopter installations. Self-testing begins when the system is turned on, and continues until turnoff. Faults detected result in a FAIL annunciation. Non-volatile memory means that the last frequency selected is in system memory if the system is turned off, if power is interrupted, or even if the system is removed from the aircraft. The CVN-252 Navigation Control Display Unit is designed to interface with Chelton FliteLine Navigation Radios (CVN-251), Chelton Series III Navigation Radios (VN-411B in the VNS 41 System), and Collins Navigation Radios with the ARINC 410 (2x5) Interfaces. Limitations NOTE: Installations of the CVN-252, and CCN-955 with the Series III or ARINC-410 digital interfaces which include the optional DME Hold functionality are subject to certain limitations. In these installations, the aircraft shall provide indication of the DME Hold status on equipment other than the FliteLine Control Display and within the pilot's primary field of view. Failure to meet these limitation guidelines violates the installation guidance set forth in this manual and may lead to an unsafe aircraft operating condition.

FLITELINE AVIONICS SYSTEM PILOT’S GUIDE Page 28 Publication No. 150-047012 Dec 2005 Rev. D Operating the CVN-252 1. Set the MODE SELECTOR to ON. 2. If these are not the desired frequencies, rotate the FREQUENCY KNOBS until the desired frequency is displayed on the bottom portion of the display 3. Press and release the FREQUENCY TRANSFER button. This exchanges the two displayed frequencies. The desired frequency is now active and may be used immediately. 4. Adjust the VOLUME CONTROL for the desired audio level. 5. Rotate the FREQUENCY KNOBS until the desired standby frequency appears on the bottom portion of the display. NOTE: To tune the active frequency only (without first tuning the standby and then "flipping" the frequencies), press and hold the FREQUENCY TRANSFER button for two seconds, then release it. This temporarily removes the standby frequency from the display. Now the FREQUENCY KNOBS may be used to change the active frequency. The active frequency may be used immediately. To restore the standby frequency to the display, press and hold the FREQUENCY TRANSFER button two seconds.
FLITELINE AVIONICS SYSTEM PILOT’S GUIDE Publication No. 150-047012 Page 29 Rev. D Dec 2005 CVN-252 Notes 1. The FREQUENCY SELECTOR KNOBS tune the navigational radio receiver directly. The Series III and FliteLine radios digitally transmit the actual frequency to which the receiver is tuned. The transceiver may also be tuned by an external ARINC 429 digital data bus. 2. The VOLUME control on the CVN-252 Control Display does not adjust the volume of the Marker Beacon receiver in the navigation receiver. This volume is preset. Typically, Marker Beacon volume is adjusted by a control on an audio control panel. 3. Display intensity and panel lighting are controlled by external dimmer controls. 4. Pressing and holding the FREQUENCY TRANSFER button for at least 7 seconds before releasing it sets the active frequency to 108.00 MHZ and puts the unit into active tuning mode. Because the display is controlled by the receiver (see Note 1 above), the receiver will tune to this frequency even if the display is defective. From the known reference of 108.00 MHz as a starting point, any other frequency may be selected by counting detents. Each clockwise detent of the outer knob is one MHz difference (108, 109, 110, etc.). Each clockwise detent of the inner knob is .05 MHz difference (.00, .05, .10, .15, etc.). For example, rotating the outer knob clockwise three detents would put the frequency at 111.00 MHz. Then rotating the inner knob clockwise three detents would then put the frequency at 111.15 MHz. 5. The FREQUENCY SELECTOR knobs rotate continuously through all detents without end stops. For example, the next clockwise detent of the outer knob after 117 is 108; the next clockwise detent of the inner knob after .95 is 00. 6. Pressing and holding the left pushbutton (PWR) for more than 1 second will trigger the system to shutdown. A warning screen will display a countdown. Releasing the PWR button before the count has expired will return the unit to the display screen active prior to initiating the shutdown. Should the system become unresponsive, a hardware failsafe shutdown can be initiated. Under this circumstance, press and hold the PWR button for 12-15 seconds. There is no indication other than actual system shutdown and an audible click.
FLITELINE AVIONICS SYSTEM PILOT’S GUIDE Page 30 Publication No. 150-047012 Dec 2005 Rev. D General Description SD-442 The SD-442 is a panel mounted DME Selector Display providing the pilot the means to control the CDM-451 modes and to display DME information. The unit provides a full time display of distance and ground speed to either the NAV 1 or NAV 2 selected VORTAC. Annunciation of the active NAV system is displayed below the distance readout. The system permits holding the active station frequency in memory, thus freeing the active navigation receiver for channeling. Annunciation of the hold (HLD) mode is provided below the displayed held NAV frequency.
FLITELINE AVIONICS SYSTEM PILOT’S GUIDE Publication No. 150-047012 Page 31 Rev. D Dec 2005 The SD-442 has only three controls. Each is a momentary, spring-loaded type that releases when finger pressure is removed. On-off power is through an external switch such as a radio or avionics master switch, or a dedicated DME switch. Volume control of DME station identification audio is also external, typically located on an audio panel. NAV - Alternately places annunciator 1, 2, or RNV in display. 1 - Selects NAV System 1 as the controller of the DME channel. 2 - Selects NAV System 2 as the controller of the DME channel. RNV - Allows the SD-442 Selector Display to be used as a "repeater" display or RNAV-computed distance to a waypoint and ground speed. This allows RNAV data to be available during times it might not be displayed by the RNAV System (for example, when other data is selected for display on some types of RNAV's). HOLD - Pressing and releasing this switch does the following: A. Locks the appropriate channel of the DME frequency in use. Aircraft wiring will affect the way in which the hold feature works. In some installations, pin 58 ground, the hold switch will only place the corresponding channel in hold. In others, pin 58 open, the hold switch will place the displayed channel into hold. B. Displays the current NAV frequency that determines the DME channel. C. Disconnects control of the DME from the NAV Receiver. D. Displays annunciation HLD. The purpose of this switch is to allow the NAV Receiver to be set to other frequencies without affecting DME operations. The DME continues to function on its "holding" channel. Pressing and releasing this switch while in the HLD mode will return control back to the indicated NAV System (1 or 2).
FLITELINE AVIONICS SYSTEM PILOT’S GUIDE Page 32 Publication No. 150-047012 Dec 2005 Rev. D TTS - (Time-To-Station) While this switch is held pressed, time-to-station will be shown on the display above the switch. When the switch is released, the display returns to its previous readout of ground speed. If in hold when the TTS switch is pressed, the HLD FREQ on the display will blink twice to alert the pilot. NOTE: When DME is being tuned by an MLS, receive DME hold is inhibited.

D FliteLine Automatic Direction Finder (ADF) General Description The Chelton CDF-552 ADF Control Display provides control to Automatic Direction Finding radios enabling reception of low-frequency navigational aids and AM broadcast stations in the 190.0 – 1860 kHz frequency range. The CDF-552 provides a direct replacement of the Series III CD-432B Control Display Unit, for control of the DF-431B in the DFS-43A system. The CDF-552 Control Display along with an ADF radio system provides accurate, dependable reception of enroute non-directional beacons (NDB), Locator Outer Markers (LOM), and commercial AM broadcast stations. Microprocessor circuitry controls operation, processes signals, performs self -calibration, and provides full-time self -diagnostics. The CDF-552 may be used with Electronics Flight Instrument Systems (EFIS) or in conjunction with the other Chelton VHF Navigation Systems for course deviation display. The CDF-552 configured for Series III or FliteLine displays frequencies in the range 190 kHz to 1860 kHz and the international marine HF distress frequency of 2182 kHz. The CDF-552 configured for BCD tuning displays frequencies in the range 190.0 kHz to 1749.5 kHz. The active and standby frequency are displayed simultaneously and stored in nonvolatile memory. Switching between the two is done by simply pressing a frequency transfer button below the displayed frequencies. The CDF-552 Automatic Direction Finding (ADF) Control Display Unit is designed to interface with the Chelton Series III ADF Radio (DF-431B in the DFS 43 system), and Collins ADF Radios with the BCD Parallel Tuning Interface.

D FliteLine Dual VHF COM and VHF NAV Control Display System General Description The Chelton CCN-955 Com/Nav Control Display Unit combines the capabilities of the CVC-152 and CVN-252 Control Displays. The CCN-955 splits the screen displaying the communication transceiver data on the upper half and the navigational data on the lower half. Despite combining the two radio functions all functionality remains operationally equivalent. The CCN-955 adds functionality to the Power (on/off) button allowing it to be used as a momentary button to toggle between the Communication and Navigation controls. The CVC-955 is designed to interface with Chelton FliteLine Communications Radios (CVC-151) and Navigation Radios (CVN-251), Chelton Series III Communications Radios (VC-401B and VC-401C in the VCS 40 systems) and Navigation Radio (VN-411B in the VNS 41 system), and Collins Communication and Navigation Radios with the ARINC 410 (2x5) Interfaces. Limitations NOTE: Installations of the CVN-252, and CCN-955 with the Series III or ARINC-410 digital interfaces which include the optional DME Hold functionality are subject to certain limitations. In these installations, the aircraft shall provide indication of the DME Hold status on equipment other than the FliteLine Control Display and within the pilot's primary field of view. Failure to meet these limitation guidelines violates the installation guidance set forth in this manual and may lead to an unsafe aircraft operating condition.

D Dec 2005 FliteLine ATC Transponder System (FliteXPDR) General Description CTR-352 The CTR-352 Control Display Unit provides a simultaneous control of up to two Mode A/C transponders. The CTR-352 Control display provides tuning of the ATC 4096 Code with a special VFR Quicktune feature to rapidly change the ATC code to 1200. The IDENT Annunciator (ID) appears in the display when the Transponder is replying to interrogation from the ATC ground station. When the CTR-352 Control Display Unit is turned on, a diagnosis of all critical circuits begins, and continues until the System is turned off. If a fault is detected at any time, a failure annunciation appears in the display. The CTR-352 Control Display Unit has a nonvolatile memory which allows it to remember the code displayed, indefinitely, even when power is removed. This feature prevents momentary power interrupts from affecting the system, and allows the last code used to appear immediately when the System is turned on. The CVC-352 Communication Control Display Unit is designed to interface with Chelton FliteLine ATC Transponder Radios (CTR-351), and Collins Transponder Radios with the ARINC 410 (2x5) Interfaces.

FLITELINE AVIONICS SYSTEM PILOT’S GUIDE Page 60 Publication No. 150-047012 Dec 2005 Rev. D Operating the CTR-352 ARINC-410 (Octal) Interface 1. Set the MODE SELECTOR to ON. 2. If the code displayed is not the one desired, rotate the CURSOR CONTROL until the ATC Code surrounds CURSOR BOX. Rotate the right inner knob to adjust the lower two digits from 00-77. Rotate the right outer knob to adjust the upper two digits from 00-77. 3. If the VFR code is desired press and hold the right pushbutton until “1200” is displayed. 4. To enable Altitude Reporting on aircraft equipped with an optional digitizing pressure encoder rotate the MODE SELECTOR to ALT. 5. If it becomes necessary to suppress all replies from the ATC ground station, rotate the MODE SELECTOR to SBY.
FLITELINE AVIONICS SYSTEM PILOT’S GUIDE Publication No. 150-047012 Page 61 Rev. D Dec 2005 CTR-352 Notes 1. When changing the ATC code, care should be made so as to avoid inadvertently selection of codes 7500, 7600, and 7700. For example, tuning upwards from 2700 to 7200 (rather than downward which would pass through the emergency frequencies) will help avoid triggering automated grounds stations. 2. Pressing and holding the left pushbutton (PWR) for more than 1 second will trigger the system to shutdown. A warning screen will display a countdown. Releasing the PWR button before the count has expired will return the unit to the display screen active prior to initiating the shutdown. Should the system become unresponsive, a hardware failsafe shutdown can be initiated. Under this circumstance, press and hold the PWR button for 12-15 seconds. There is no indication other than actual system shutdown and an audible click.

FLITELINE AVIONICS SYSTEM PILOT’S GUIDE Publication No. 150-047012 Page 63 Rev. D Dec 2005 FliteLogic EFIS Tuning Features General Description The CVC-152, CVN-252, and CCN-955 are designed to integrate with the Chelton FliteLogic Electronics Flight Instrument System (EFIS). The Control Displays receive COM and NAV tuning frequencies from the EFIS database to reduce pilot workload. Operating the Control Displays with EFIS 1. On the EFIS, display the information for the facility (see Waypoint Information (NavData), page 5-38 EFIS Manual). 2. On the EFIS, turn the control knob to highlight the desired frequency. 3. Menu functions will appear as appropriate to send the frequency to the com or nav radios. 3. On the EFIS, press TO COM1 or TO COM2 (or TO NAV1 or TO NAV2) to send the frequency to the standby position of the COM (or NAV) radio. 4. On the Control Display, when in ARINC410 mode, observe the standby frequency flashes and the frequency instantly changes. 5. On the Control Display, when in Series III or FliteLine mode, observe the standby frequency briefly flashes the word EFIS for up to 2 seconds while the frequency synchronizes between the Control Display and Radio. 4. On the EFIS, Press BACK or EXIT when finished. 5. On the Control Display, press the frequency transfer button (right pushbutton) to move the frequency from standby to active. EFIS and Control Display Integration notes: 1. The standby area will not flash when in COM and NAV modes where the actual standby frequency is not normally displayed a. NAV – HLD, BRG, RAD, b. COM – 2. The control display executes the last EFIS frequency update upon entering a mode in which the standby frequency is displayed.
