17 Figure 1-1: System Interface Overview 1.2 FUNCTIONAL DESCRIPTION NGT-1000 The NGT-1000 contains an integrated GPS receiver and UAT transceiver providing output functionality of the Automatic Dependent Surveillance Broadcast (ADS-B). The integrated GPS receiver provides own aircraft information (position, velocity, track (or ground track), etc.) for ADS-B Out messages. The GPS is not intended as a position source to a navigation management unit that outputs deviation commands keyed to a desired flight path. The ADS-B datalink transmits using the 978 MHz Universal Access Transceiver (UAT). The ADS-B out function improves situational awareness and flight safety by providing aircraft position, velocity, and heading/track information that is automatically transmitted to other aircraft and ground stations providing immediate surveillance of air-to-air traffic. The unit uses a DCM that is installed in the wiring bundle of the mating connector to store configuration data. The following paragraphs provide an overview of each of these functions. The unit is equipped with IDENT capability that activates the Special Position Identification (SPI) pulse for 18 seconds. When permitted, the transmission of own ship identification can be inhibited using the Anonymous Mode function provided by the CP-2500 control panel. This may only be accomplished when VFR Mode is active General Information Page 1-3 Revision G

18 1.2.2 NGT-2000/-2500 The NGT-2000/-2500 contains an integrated GPS receiver and UAT transceiver providing input and output functionality of the Automatic Dependent Surveillance Broadcast (ADS-B). Depending on the model/configuration, the unit has ARINC 429, RS-422 (Wx out only), and RS-232 data ports used to interface with traffic (RS-232 and ARINC 429 only), weather (RS-232 and RS-422 only) displays. The unit uses a DCM that is installed in the wiring bundle of the mating connector to store configuration data. The following paragraphs provide an overview of each of these functions. The integrated GPS receiver provides own aircraft information (position, velocity, track (or ground track), etc.) for ADS-B Out messages and traffic display. The GPS is not intended as a position source to a navigation management unit that outputs deviation commands keyed to a desired flight path. The ADS-B datalink receives and transmits using the 978 MHz Universal Access Transceiver (UAT). The ADS-B out function improves situational awareness and flight safety by providing aircraft position, velocity, and heading/track information (DTIF displays only) that is automatically transmitted to other aircraft and ground stations providing immediate surveillance of air-to-air traffic. The ADS-B In function provides own aircraft with Enhanced Visual Acquisition (EVAcq) traffic information and Flight Information Service Broadcast (FIS-B). The NGT-2000/-2500 Interfaces with RS-232 compatible transponders for the input of the Mode A squawk Code and mode of operation from the aircraft s existing Air Traffic Control Radar Beacon System (ATCRBS) transponder or through a dedicated MODE A control panel interface. The unit is equipped with IDENT capability that activates the Special Position Identification (SPI) pulse for 18 seconds. When permitted, the transmission of own ship identification can be inhibited using the Anonymous Mode function provided by the CP-2500 control panel. This may only be accomplished when VFR Mode is active GPS Functional Overview The GPS function utilizes signals from Global Positioning System (GPS) satellite constellation and Satellite-Based Augmentation Systems (SBAS) such as the USA Wide Area Augmentation System (WAAS), European EGNOS, Indian GAGAN and the Japanese MSAS. Currently it supports WAAS and WAAS compatible SBAS systems. This internal GPS function provides position, velocity, time and integrity (NIC, NAC etc) information to the ADS-B functions and is ADS-B rule compliant with the position source requirements of AC20-165A Multiple Source Inputs Operation The NGT-1000/-2000/-2500 have multiple altitude source connections available. There is an option, through the detachable configuration module (DCM), for connecting RS-232 serial altitude source or Grey code altitude source, however only one source can be connected at a time. The pressure altitude source is a required input and must be the same source used for the mode "C" transponder if so equipped. Page 1-4 General Information Revision G

19 1.2.5 Discrete Inputs and Outputs The NGT-1000/-2000/-2500 have discrete inputs and outputs that can be used in place of some functions that are not available to equipment that is compatible with the NGT-1000/-2000/ See Figure 1-1. The discrete input is typically active (ON) when the input is grounded. The WOW input discrete is optional. The input signals the On Ground status to the NGT-1000/- 2000/-2500 via a gear switch, squat switch, airspeed monitor, or a collective switch. The IDENT switch is optional. It is required only if command to activate the SPI and transmit an IDENT pulse is not available with other equipment. It is recommended when using the CP-2500 to allow IDENT entry to both the transponder and the UAT device with one button push. An IDENT pulse highlights the aircraft s symbol on the ATC s radar screen and is identified on the control panel when active. The Standby/Operate Switch is required if a CP-2500 is not a part of the installation. It is used to interrupt ADS-B out transmission (standby position). Setting this discrete to Standby inhibits UAT transmissions and turns the ADS-B Out Fail lamp ON. Note - This discrete input is disabled when using a CP ADS-B Out Fail Lamp is required if a CP-2500 is not a part of the installation and is recommended when the CP-2500 is part of the installation. The lamp provides the following indications: 1. If the Fail lamp is flashing at a fast rate (2 flashes per second), then a Mode A code mismatch is detected between the XPDR Out and the UAT-Out. 2. If the Fail lamp is flashing at a slow rate (1 flash per 2 seconds), then the unit is unable to transmit GPS position data because the aircraft position information is invalid (GPS is acquiring satellites). Note - The lamp stops flashing and remains illuminated (ON) after 2 minutes if GPS satellites are not acquired. 3. If the Fail lamp turns ON and does not flash, then the unit is unable to transmit due to a detected failure. Note - This can also be caused by the CP-2500 or the Operate/Standby switch set to "Standby. The No ADS-B Coverage lamp is required by the NGT-2000/-2500 if the CP-2500 is not installed. The lamp is used to indicate that the unit is not receiving an ADS-B ground station signal Transponder Interface If the aircraft is equipped with a non-compatible transponder, then the aircraft needs a CP-2500 Control Panel installed. When used with the CP-2500, the NGT-1000/-2000/-2500 can wirelessly intercept the Mode A squawk Code from the aircraft s existing ATCRBS transponder and conduct a cross check between the transponder broadcast value and the setting of the NGT-1000/-2000/-2500 Mode A control panel setting to ensure the consistency in selected Mode A squawk code selections. If the code entered from the control panel does not match the Mode A response from the transponder, then a Mode A mismatch failure message is displayed on the control panel and the last known mode A Code is used in the UAT Message transmissions. Pilot action is required to assure that the codes set into the transponder and the CP-2500 always match. If the aircraft is not equipped with a transponder, then the CP-2500 control panel is required to provide squawk code data and operation mode control (i.e. Standby, On, ALT modes). Compatible transponders are listed in Table 1-15 in paragraph General Information Page 1-5 Revision G

20 1.2.7 ADS-B System Overview The Automatic Dependent Surveillance-Broadcast (ADS-B) improves situational awareness and flight safety by providing real time traffic information. The ADS-B Out function used by the NGT-1000/-2000/-2500 is used to periodically broadcast (without interrogation) information on a 978 MHz UAT link about the aircraft that includes aircraft identification, position, altitude, velocity and other aircraft status information. The ADS-B In function used by the NGT-2000/-2500 is used to receive ground station supported TIS-B and ADS-R traffic, and direct communication with nearby like equipped aircraft (UAT) using ADS-B Out. The traffic display shows the relative position of ADS-B or standard traffic using text, shapes, and colors. ADS-B also provides similar information on ADS-B equipped ground vehicles. The effective surveillance range is 60 nmi and is capable of maintaining report messages for a minimum of 120 UAT ADS-B participants simultaneously. To reduce display clutter, only a set number of other aircraft of the highest priority are displayed at a time FIS-B Functional Overview The Flight Information Services - Broadcast (FIS-B) function used by the NGT-2000/-2500 provides pilots with a cockpit display of certain aviation weather and aeronautical information for awareness of own aircraft location with respect to reported weather, including hazardous meteorological conditions (CONUS NEXRAD /AIRMETS/ SIGMETS/ NOTAMS/ METARS, etc) and SUA status and TAF (FIS-B products). NOTE CONUS and Regional NEXRAD may not always contain complete data. The data is refreshed every 15 minutes and it is likely to be updated in a future cycle. FIS-B is advisory information only and is intended to enhance pilot decision-making during strategic flight planning. FIS-B augments traditional sources of this information such as ATC and Flight Service Station (FSS). FIS-B information is provided over the ADS-B Services network on the 978 MHz UAT link when in ground station coverage Enhanced Visual Acquisition Functional Overview The Enhanced Visual Acquisition (EVAcq) function used by the NGT-2000/-2500 provides flight crews with a display of nearby traffic relative to own aircraft (Cockpit Display of Traffic Information Traffic Display) to assist with visually acquiring traffic out the window and provide traffic situational awareness beyond visual range. Each displayed traffic symbol conveys aircraft position, vertical trend and altitude information (if available). Traffic on the display (i.e. STIF/CDTI displays or some PED applications) can be selected by the flight crew to obtain additional traffic information such as flight identification and ground speed. The EVAcq function can display traffic on either an integrated traffic display (STIF or DTIF) or an external traffic display (i.e. PED). The maximum number of other aircraft sent to the display is dependent on the interface detailed below: ARINC 429 STIF: 28 In-air aircraft RS-422: 30 In-air and 30 On-Ground aircraft (future option) RS-232: 30 In-air and 30 On-Ground aircraft Data received via a UAT link (Ground stations- when in a coverage area) is the ADS-R Rebroadcast and TIS-B Traffic Information Service Broadcast (traffic information used by EVAcq). ADS-B (UAT) traffic can also be received directly from another UAT equipped aircraft. TIS-B traffic and ADS-R traffic can only be received when in the coverage area of an ADS-B ground station.

21 1.3 EQUIPMENT DESCRIPTIONS The NGT-1000/-2000/-2500 are equipped with a main 62 pin sub-d connector (J2) and RF connectors (UAT and GPS). A USB port (J1) is available to establish communication between the unit and a maintenance computer for installation and maintenance activities. Table 1-3 describes the available builtin interfaces. The NGT-1000 is capable of ADS-B out only. Figure 1-2 shows the NGT-1000 system interface. The NGT-2000/-2500 is capable of the following functionality; ADS-B out, ADS-B in: UAT, ADS-R, TIS-B (traffic), FIS-B weather, TFRs, and NOTAMS. Figure 1-3 shows the NGT-2000 system interface. Figure 1-4 shows the NGT-2500 system interface. The NGT-2000/-2500 provides an RS-232 output that can be used to display UAT ADS-B traffic as well as FIS-B weather information when an external WiFi Serial Adapter is connected to transmit the received weather data to a commercial PED (i.e. Personal Electronic Device) like a PED. The NGT-2500 outputs ARINC 429 to interface with an onboard cockpit display of traffic information display (STIF or DTIF) for the display of own ship (DTIF only) and traffic information. The NGT-2500 can interface with a RS-422 data bus output that may be interfaced to a display to provide weather or traffic (future option) information. The ADS-B Out function is used to broadcast (without interrogation) periodic information about the aircraft that includes aircraft identification, position, altitude, velocity and other aircraft status information. The UAT ADS-B In function supports the reception of ADS-B on a 978 MHz UAT link. The ADS-B In data contains information about proximate UAT aircraft such as aircraft position, velocity, direction, etc. and also receives FIS-B, ADS-R and TIS-B data from ground stations (when within ground station coverage areas). The FIS-B function provides pilots and flight crews with a cockpit display of certain aviation weather and aeronautical information for awareness of own aircraft location with respect to reported weather, including hazardous meteorological conditions and NAS status indicators. FIS-B is advisory information only and is intended to enhance pilot decision-making during strategic flight planning. FIS-B augments traditional sources of this information such as ATC, Flight Service Station (FSS), and Aircraft Operational Communications Center. FIS-B information is provided over the ADS-B Services network on the 978 MHz UAT link when within ground station coverage areas. Refer to Appendix A for detailed information on the interface options. The traffic and weather (RS-232) display interfaces are available to the NGT The traffic (RS-232 and ARINC 429 only) and weather (RS-232 and RS-422 only) display interfaces are available to the NGT An unlock code is required to activate the NGT-2500 from the NGT-2000/-2500 platform.

28 Deviation Notes: Deviation 1: TSO-C145c TSO requires use of DO-160E for environmental qualification testing; DO-160G was used instead. Deviation 2: TSO-C145c, C154c, TSO-C157a, TSO-C195a Per the guidance in FAA Order c, the UAT devices are marked with the primary TSO along with a reference to the for the other TSO information (other applicable TSO s, deviations, etc.). Deviation 3: TSO-C145c, TSO-C154c, TSO-C157a, TSO-C195a The NGT-1000/-2000/-2500 utilizes a Maintenance Computer (i.e., a special tool ) as its primary support tool required for installation and debug effort. All installations will require that the Maintenance Computer be used to verify the software part number that is stored electronically in the unit thereby ensuring the part has been installed in compliance to the type design data. All software updates will also require that the Maintenance Computer be used to verify the software part number that is stored electronically in the unit thereby ensuring the part is in compliance to the type design data. Deviation 4: TSO-C154c The RF radiated emissions to exceed the Category L requirement for the RF radiated emission limit in the following frequency bands: 1956 MHz ± 2.25 MHz (2nd Transmitter harmonic) Exceeds Cat L by as much as 30 db 2934 MHz ± 1 MHz (3rd Transmitter harmonic) Exceeds Cat L by as much as 14 db 3912 MHz ± 1 MHz (4th Transmitter harmonic) Exceeds Cat L by as much as 15 db 4890 MHZ ± 1 MHz (5th Transmitter harmonic) Exceeds Cat L by as much as 8 db 5868 MHZ ± 1 MHz (6th Transmitter harmonic) Exceeds Cat L by as much as 3 db Meets DO-282B spectrum reply bounds. There is limited average radiated power in the deviation magnitudes due to the very low duty cycle. There are no defined aeronautical safety related operations utilizing these frequencies. For this deviation, the NGT-1000/-2000/-2500 will direct the installer to specifically verify noninterference with other avionic systems for these frequencies (See Installation Checkout section) Non-TSO Functions The NGT-1000/-2000/-2500 Release 1 and DCM Release 1 do not have any Non-TSO functions Incomplete-TSO Application FIS-B Equipment Class The NGT-2000/-2500 is compliant to Class 2 of TSO-C157a, except that it does not contain a display Failure Classification The below summarizes the potential hazards associated with the NGT-1000/-2000/-2500 and the associated failure condition severity classifications per AC E. 1.

57 2.3.2 Antenna Installation Guidelines This information provides general installation guidance to ensure the installed antennas meet the requirements for the NGT-1000/-2000/ Installation approval for the GPS and L-band antennas is not provided by the instructions provided in this manual. GPS and L-band antenna cables should be clearly marked as both connections use TNC connectors. Cable requirements are located in paragraph Cable vendors and approved antenna manufactures are located in the General Information section. An example of antenna placement is shown in Figure 2-7. Refer to the aircraft manufacturer's data and the antenna manufacturer's installation instructions to mount the antenna. The installer may use other FAA approved data to gain a separate antenna installation approval. Figure 2-7: Example of Antenna Mounting Locations GPS Antenna The GPS antenna performance is critical to the performance of the NGT-1000/-2000/ The antenna must meet the minimum performance requirements for the NGT-1000/-2000/ The antennas listed in the General Information section meet these requirements. The antenna performance is critical to operation of GPS in the unit. The antennas listed in this manual meet the requirements of TSO-C190. The unit may be installed on aircraft with existing antenna if that antenna complies with TSO-C144a and has been tested for compatibility. The performance of the unit is affected by the gain, noise figure, impedance, and frequency selectivity characteristics of the antenna. The unit should be used only with the recommended antenna and cable. Use of other antennas or cables may not meet all the performance characteristics required by TSO-C190 or if applicable TSO-C144a. The cable including connectors, loss should not exceed 10dB Installation Page 2-13 Revision G

58 GPS Antenna Location The following guidance provides information to aid the installer in determining the best location is selected for the installation of the GPS Antenna. The installation guidelines presented here meet the intent of AC D Chapter 13, Section NOTE Not all the listed installation guidelines may be possible on all aircraft. The guidelines are listed in order of importance. The chances of optimal signal strength are decreased if the guidelines are not followed. 1. The antenna must be located on the top of the aircraft and should be mounted in a location to minimize the effects of airframe shadowing during typical maneuvers. Typically mounting farther away from the tail section reduces signal blockage seen by the antenna. 2. Mount the antenna as close to level as possible with respect to the normal cruise flight attitude of the aircraft. If the normal flight attitude is not known, substitute with the waterline, which is typically referenced as level while performing a weight and balance check. A shim may be used to level the antenna. 3. The antenna should be mounted no closer than 3 feet from any VHF COMM antenna or any other antenna, which may emit harmonic interference at the L1 frequency of MHz. An aircraft EMI check can verify the degradation of GPS in the presence of interference signals. If an EMI check reveals unacceptable interference, either insert a GPS notch filter in line with the offending VHF COMM or select a different GPS Antenna location. 4. To maintain a constant gain pattern and limit degradation by the windscreen, avoid mounting the antenna closer than 3 inches from the windscreen. 5. It is permissible to temporarily locate the GPS Antenna with a coaxial cable connected to the NGT- 1000/-2000/-2500 and check the GPS performance as described in the installation checkout section. Permanently mount the antenna once a suitable location has been verified. 6. Once the antenna mounting position has been established, route the coaxial cable from the antenna to the NGT-1000/-2000/ Proper selection of coaxial cable and assembly of connectors is critical to GPS signal performance. 7. For installations on rotorcraft, ensure that the rotor blades do not interfere with the GPS received signal. This problem has been experienced in some rotorcraft and varies with rotation rate GPS Antenna Installation Refer to the aircraft manufacturer's data and the antenna manufacturer's installation instructions to mount the antenna. The installer may use other FAA approved data to gain a separate antenna installation approval. 1. Electrical Bonding Requirements: The GPS/WAAS antenna requires a minimum ground plane radius of 7.5 inches around the perimeter of the antenna. For metal aircraft, the surrounding metal skin on which the antenna is mounted supplies the ground plane. For non-metal aircraft, the ground plane can be composed of heavy duty aluminum foil tape, such as 3M P/N 438 or other adhesive backed dead soft aluminum foil minimum inches thick. It should be noted that if the antenna is struck by lightning, the foil by itself may not be sufficient to dissipate lightning currents. Additional protection may be needed depending on the construction of the structure to which the antenna is mounted. The electrical bonding requirements stated in paragraph 2.3 step 2 must be met. To prepare an aluminum surface for proper bonding, refer to SAE ARP1870A. 2. Connection to the antenna should be made in accordance with the system interconnect diagram Figure 2-3. Page 2-14 Installation Revision G

59 L-Band (UAT/978) Antenna The UAT/978 antenna must meet the minimum performance requirements for the NGT-1000/-2000/ Only the antennas listed in the General Information section have been tested. Antennas meeting the minimum performance specifications needed by the NGT-1000/-2000/-2500 may already be installed in the aircraft and may be available for use. Use the antenna location information below to verify an existing antenna location is acceptable for use. Installation approval for the UAT Antenna is not provided through this Manual L-Band (UAT/978) Antenna Location The UAT/978 antenna installation should be installed in accordance with AC B Chapter 3. The following guidance provides information to aid the installer in determining that the best location is selected for the installation of the L-band Antenna. The UAT/978 antenna must be mounted vertically on the bottom of the aircraft fuselage. The antenna shall be located to minimize obstruction to fields in the horizontal plane. The total attenuation including connectors shall not exceed 1.5 db. Based on this, the length of the cable can be decided assuming RG-400 cable. RG type coaxial cable insertion loss can vary significantly between manufacturers. Refer to the cable manufacturer's specification sheet for actual attenuation (insertion loss) for the cable being used. The UAT/978 antenna should be located away from major protrusions, such as engine(s), propeller(s), and antenna masts. It should be as far as practical from landing gear doors, access doors, or other openings that could affect its radiation pattern. The UAT/978 antenna must be mounted no closer than 20 inches from any FADEC (Full Authority Digital Engine Control). The UAT/978 antenna must be mounted no closer than 7 feet to any DME antenna. The UAT/978 antenna must be mounted no closer than 36 inches to any TAS/TCAS/Transponder/ Com antenna. Refer to Table 2-1 for maximum transponder distances. Table 2-1: Maximum UAT Antenna to Transponder Antenna Separation UAT ANTENNA CABLE ASSEMBLY CABLE LOSS (1) Up to 1.0 db MAXIMUM ANTENNA SPACING (2) 137 inches 1.0 db < Cable Loss < 1.5 db 129 inches Note (1) Cable assembly cable loss includes loss of the coaxial cable with connectors. Note (2) Measured from center of UAT/978 Antenna to the center of transponder antenna. When the NGT-1000/-2000/-2500 is configured to communicate with the aircraft transponder using the self-interrogation feature (CP-2500 installed), the following antenna guidelines must also be followed: a. Deleted. b. The bottom UAT/978 Antenna must be mounted no further from the transponder antenna than specified in Table Installation Page 2-15 Revision G

60 L-Band (UAT/978) Antenna Installation Refer to the aircraft manufacturer's data and the antenna manufacturer's installation instructions to mount the antenna(s). The installer may use other FAA approved data to gain a separate antenna installation approval. Electrical Bonding Requirements: Each L-Band antenna requires a minimum ground plane radius of 12 inches of contiguous metal (no access panels, etc.) around the perimeter of the antenna. For metal aircraft, the surrounding metal skin on which the antenna is mounted supplies the ground plane. For non-metal aircraft, the ground plane can be composed of heavy duty aluminum foil tape, such as 3M P/N 438 or other adhesive backed dead soft aluminum foil minimum inches thick. It should be noted that if the antenna is struck by lightning, the foil by itself may not be sufficient to dissipate lightning currents. Additional protection may be needed depending on the construction of the structure to which the antenna is mounted. The electrical bonding requirements stated in paragraph 2.3 step 2 must be met. Connection to the antenna should be made in accordance with the system interconnect diagram Figure 2-3. GPS and L-band antenna cables should be clearly marked as both connections use TNC connectors. Refer to Table 2-1 for Antenna Cables for UAT Antenna cable loss and minimum antenna spacing requirements. Refer to General Information Section - lists some suitable cable types. Suitable 50 ohm, doubleshielded coaxial cable assembly that meets airworthiness requirements and the acceptable attenuation requirements (including connectors) may be used. When computing cable loss refer to cable/connector manufacture data.

62 If the CP-2500 is not installed then whatever is installed (i.e. compatible control panel, transponder, and cockpit switches/lamps) must be able to support the following functions: o Enter Mode A Squawk Code o Set Operation Mode or Standby / Operate (switch), ON, ALT, and Ident o VFR Code Select o IDENT (or a IDENT switch) o Display Transponder Code Mismatch Message (or ADS-B Out Fail lamp) o Display Fault Messages (or minimum ADS-B Out Fail lamp and No ADS-B Coverage lamp) If installed, the ADS-B Out Fail lamp (amber) has the following functions. o Flashes at a slow rate (1 flash per 2 seconds) while the GPS is initializing. Check by cycling power to the unit. Flashing will last only 2 minutes before the lamp stays ON (this indicates the unit is unable to transmit GPS position due to aircraft position information being invalid.) o Flashes at a fast rate (2 flashes per second) if a code mismatch is detected. Check by entering the different Mode A code from the one being transmitted by the transponder. Note - Occurs with CP-2500 installations only. o The lamp is ON when the ADS-B has failed or if the Standby / Operate switch is set to Standby or CP-2500 (if installed) is set to standby. If installed the No ADS-B Coverage lamp (blue) indicates if a ground station signal is being detected. The lamp is OFF when a signal is detected and ON when a ground station signal is not detected. If installed the IDENT and Standby / Operate switches provide the following functions: o Pressing the remote IDENT switch activates the IDENT message to be sent by the unit via ADS- B Out. An IDENT pulse highlights the aircraft s symbol on the ATC s radar screen and is identified on the control panel when active. o The Standby / Operate switch is used to stop ADS-B Out transmission for standby operation. Setting this switch to Standby turns the ADS-B Out Fail lamp ON. This switch should always be in the "operate" mode unless otherwise directed by ATC CP-2500 Control Panel The CP-2500 is specifically designed for operation with the NGT-1000/-2000/ The operational information provided in this section is limited.

68 3.6 SELECT CONFIGURATION OPTIONS This procedure is used to configure the NGT-1000/-2000/-2500s and must be completed prior to performing the Installation Checkout for first time installations. The Log Sheet provided in Appendix C should be filled out prior to this procedure and maintained with the aircraft s permanent records. If a configuration file has already been created using the Lynx MAT Backup function, then it may be used to load the data options. The configuration restore procedure is located in the maintenance section of this manual. An unlock code is required to enable the model NGT Contact L-3 Avionics Systems Customer Service to obtain the code. If the Lynx MAT is not connected or is disconnected the left side panel color changes to a light gray and the Not Connected message is displayed at the bottom of the tool screen. Re-connect by doing the following - from the Lynx MAT panel select Connect Appliance USB. This is required each time the unit power is cycled. Place the curser over option titles to view tool tips (not always available). A DCM read monitor that checks the interface of the unit and DCM is located at the top of the each configuration page. A Warning message is shown when the user first attempts an operation that requires confirmation from the user stating Changes should be done by trained service personnel. The user will need to press the confirm button to acknowledge this warning. No configuration changes take effect until they are entered, applied, and power is cycled to the unit. Pressing Apply from any setup/configuration/modify screen applies all changes from all screens. These procedures assume the following: Power is being supplied to the NGT-1000/-2000/-2500 and system components (i.e. antenna, display, and controllers). The Lynx MAT is active on the MPC.

70 Aircraft Emitter Category. This information provides an indication of the aircrafts size and performance capabilities. Emitter categories are defined below: EMITTER CATEGORY Unknown Light Small Large High Vortex Large Heavy High Performance Rotorcraft Glider/Sailplane Lighter than Air Parachutist Ultra Light UAV Space Surface - Emergency Surface - Service Point Obstacle Cluster Obstacle Line Obstacle DESCRIPTION No aircraft type information. If no emitter category fits the installation, seek guidance from the FAA. Light (ICAO) < 15,500 lbs. This includes very light aircraft (light sport aircraft) that do not meet the requirements of 14 CFR Small 15,500 to 75,000 lbs. Large 75,000 to 300,000 lbs. High Vortex Large - 75,000 to 300,000 lbs. that has been determined to generate a high wake vortex. (e.g. B757). Heavy (ICAO) - > 300,000 lbs Highly Maneuverable > 5G acceleration and > TAS high speed. Any rotorcraft regardless of weight. Any Glider/Sailplane regardless of weight. Any lighter than air (airship or balloon) regardless of weight. Sky diver A vehicle that meets the requirements of 14 CFR Light sport aircraft should not use the ultra light emitter category unless they meet 14 CFR Any unmanned aerial vehicle or unmanned aircraft system regardless of weight. Trans-atmospheric vehicle Emergency vehicle Service vehicle Includes tethered balloons Cluster Obstacle Line Obstacle Aircraft Length (feet). This parameter sets the aircraft dimension that will be transmitted to ATC and other aircraft. Aircraft Width (feet). This parameter sets the aircraft dimension that will be transmitted to ATC and other aircraft. Air/Ground Indication: This setting is based on the interconnect wiring for Pin 53 (Discrete Input 3 WOW). The Aircraft ground indication can be wired for electrically Open or Ground. Determine the correct setting by referring to the interconnect wiring diagram for the aircraft to. If Pin 53 (WOW input) is not part of the installation then select Not Available. Note: Selecting Ground on Ground or Open on Ground forces the Aircraft Min Ground Speed Threshold When In Air and Altitude Change For Ground To Air to be zero. Aircraft Max Ground Speed Threshold When On Ground is editable. The Ground Speed Threshold for True Track Validity is always set to 7. Aircraft Min Ground Speed Threshold When In Air (knots). This sets the minimum ground speed of the aircraft, used in determination of air - ground status while the aircraft is in - air. This may be set only when the Air/Ground Indication is set for Not Available. o For an aircraft with an air/ground discrete, this value is automatically hard coded to 0, therefore only using the discrete. o For an aircraft without an air/ground discrete, the ground speed threshold is set below which the aircraft status changes to on-ground. For non-rotorcraft, set a value of 50 % below Vs0 to be certain the on-ground setting occurs conservatively. The value is set up as the minimum speed of the aircraft in knots while in air. This value is not available for Rotorcraft because rotorcraft will not be set to on-ground after having been in-air within a given power cycle. Page 3-10 Installation Checkout Revision G

71 Aircraft Max Ground Speed Threshold When On Ground (knots). This sets the max ground speed of the aircraft, used in determination of air - ground status while the aircraft is on - Ground. This threshold must be manually set. This sets the maximum ground speed threshold at which the air/ground switch is declared as stuck on ground and at which the aircraft status is overwritten to in-air. o For a non-rotorcraft with an air/ground discrete set the threshold to the value of half the takeoff speed (Vr -50%). o For a non-rotorcraft without an air/ground discrete, set the threshold to VS0 to be conservative. o For a Rotorcraft (either with or without an air/ground discrete) set the threshold to a stationary GPS ground speed error level to ensure stationary readings are not mistakenly placing aircraft in air around 3 knots. Ground Speed Threshold for True Track Validity (knots). This is to provide an indication of the groundspeed threshold for the ownship track angle to be considered valid. This is always set to 7 and is not editable. Altitude change for ground to air (feet). This provides the minimum elevation above the ground reference for the air/ground status to be considered as In - Air. This may be set only when the Air/Ground Indication is set for Not Available. GPS Antenna Offset Lateral (feet). The GPS Antenna Offset lateral indicates the lateral distance between the longitudinal center line of the aircraft and the GPS Antenna. GPS Antenna Offset Longitudinal (feet). The GPS antenna offset longitudinal indicates the longitudinal distance between the nose of the aircraft and the GPS antenna. GPS Antenna Direction (with respect to lateral axis). Sets the direction of the GPS antenna lateral offset (left or right of the longitudinal centerline). Audio Volume. (NGT-2000/-2500 only) Use for Installation adjustment of audio output volume (Future). 3. Click on Apply after all information is entered.

78 3.8 INSTALLATION CHECKOUT This procedure validates the installation and configuration setup of the NGT-1000/-2000/-2500 and secondary equipment. Installers are advised to read through the entire procedure before performing the checkout. Take the following into consideration prior to installation. NOTE The compatible display/control panel/ped may not operate exactly as stated in this checkout. Refer to the operating instructions for the controller/display/ped for details. Perform the installation checkout procedure with aircraft on ground. Perform only those checks that are applicable to the installation. To conserve aircraft battery power, it is recommended that the aircraft be connected to an external aircraft power source during installation and checkout. An IFR-6000 (or equivalent) Ramp Test Set with UAT capabilities is required. These checks assume familiarity with the set up and operation of the ramp test set. All test equipment shall be calibrated in accordance with the manufacturer's recommendations. The CP-2500 Control Panel is specifically designed to interface with the NGT-1000/-2000/-2500 and may be used during the checkout to verify the operation of the NGT-1000/-2000/ Depending on the installation - when power is applied to the unit the following indication is observed while the GPS is initializing (acquiring a signal). o The CP-2500 shows a GPS INIT message. o The ADS-B Out Fail indicator lamp flashes at a slow rate. o (NGT-2000/-2500 only) Compatible equipment may have its own kind of message or indication. It is normal for STIF displays to indicate "DATA-FAIL" until GPS signal is acquired. (NGT-2000/-2500 only) It is normal for the No ADS-B Coverage lamp to be ON during checkout if there is not an ADS-B ground station or signal within range. Note: The lamp will not extinguish even when simulating signals with the IFR Some tests require the unit be set to Ground Test Mode. This is accomplished from the Lynx MAT by selecting Service Ground Test Overrides and setting the ground speed to greater than 7kts (which sets the unit to Operate mode) and setting the track to match the present aircraft true heading (which points the traffic on the traffic screen in the correct orientation). Press the Enable button to enter ground test mode and disable to return to normal operation mode. See Figure Note The Ground Test Override selection is removed when the unit and MPC are connected via WiFi. NOTES 1. When entering heading information into the IFR-6000 UUT HDG entry field make sure to enter either the same simulated heading as was entered into the Lynx MAT own direction field or the actual aircraft heading (true heading) as appropriate. 2. Determine true heading by adding the East Variation to the aircraft current magnetic heading or subtracting the West Variation to the aircraft current magnetic heading (e.g. airport KGRR has a 04W variation so with a magnetic heading of 290 the true heading would be 286). Go to AirNav.com and type in the airport location to find the variation for that area. Page 3-18 Installation Checkout Revision G

Verify this by viewing the Status information provided by the Lynx MAT as follows: 1. From the Lynx MAT select Service UAT GPS Status. See Figure Figure 3-16: Lynx MAT UAT GPS Status 2. Review the Bite Status and verify that no failures, indicated by a 0 in the right column. A BITE Status of 1 for BIT Value 0 indicates that the Self Test has not completed and is in progress. 3. If a failure is observed the problem must be resolved before continuing with the checkout. If the BITE Status for BIT Values 1, 2, 3, 5, 7, 9, 10, 11, 12, 14, 15, 16, 17, 18, 21, 22, 23, 25, 26, 27, 30, or 31 are 1 (failed) then cycle power to the unit and check if the fault persists. Contact L 3 Field Service before removal of the unit. If the BITE Status for BIT Value 29 (GPS Antenna is short) is 1 (failed) then cycle power to the unit. If the fault persists refer to the troubleshooting information in the maintenance section to resolve. Page 3-20 Installation Checkout Revision G

81 3.8.2 UAT GPS Functional Status The power ON self-test (PBIT) and continuous self-test (CBIT) checks for the proper operation of input/output signals. Verify this by viewing the functional status of the UAT GPS provided by the Lynx MAT as follows: 1. From the Lynx MAT select Service UAT GPS Functional Status. See Figure Review the Status and verify that no failures, indicated by a 1 in the right column, are present. 3. If a failure is observed the problem must be resolved before continuing with the checkout. Use Table 3-1 and the troubleshooting help in the maintenance section to resolve the issue.

83 3.8.3 Indicator Lamp Check Verify the following indicator lamps are functioning properly (if installed) during the checkout. These lamps are required if the control panel installed on the aircraft does not provide the indications stated below. Note The CP-2500 is capable of displaying messages for both these indications. 1. ADS-B Out Fail This lamp does the following depending on the situation: Flashes at a slow rate (1 flash per 2 seconds) while the GPS is initializing. Check by cycling power to the unit. If no GPS signal is available, the flashing lasts only 2 minutes before the lamp stays ON. Normally GPS position is acquired within 2 minutes, and the lamp extinguishes. Flashes at a fast rate (2 flashes per second) if a code mismatch is detected. Check by entering the different Mode A Code from the one being transmitted by the transponder. The amber lamp is ON when the ADS-B has failed or if the Standby / Operate switch or CP is set to Standby. 2. (NGT-2000/-2500 only) No ADS-B Coverage This blue lamp is ON if no ground station signal is detected. The lamp is OFF when a signal is detected by a ground station Discrete Switch Checks Verify the following external switches are functioning properly (if installed) during the checkout. The Ident and Standby / Operate switches are required if the control panel installed on the aircraft does not provide the functions stated below. Note The CP-2500 is capable of performing these functions. 1. Verify that the IDENT Input switch causes an IDENT annunciation on the IFR-6000 for approximately 18 +/- 10 seconds. Note Due to sampling interval of the IFR-6000, a precise reading is not obtainable on ground. 2. Set the Standby / Operate switch to Standby and verify that the ADS-B Out Fail lamp is ON, indicating a fail condition. Set the switch to Operate and verify that the ADS-B Out Fail lamp is OFF. 3. The On -Ground switch function is verified by viewing the On Ground status message on the IFR-6000 during other checkout procedures Control Panel Check The NGT-1000/-2000/-2500 requires a compatible control panel (RS-232) to operate. The instructions provided in this manual for a compatible control panel is limited. Refer to the manufacturers control panel manual for operation and checkout procedures. When interfacing to a compatible transponder there may be set up steps for the transponder that need to be done before it will communicate with the NGT-1000/-2000/ As an example the GTX 327 is required to be configured for Remote to establish communication with the NGT-1000/-2000/ Display Check The NGT-2500 may be interfaced to a compatible traffic display (ARINC 429) and weather display (RS-422). The instructions provided in this manual are generic. Refer to the manufacturers display manual for operation and checkout procedures. A functional check with the NGT-2500 is accomplished during the check of the ADS-B In, TIS-B, FIS-B and any other checks requiring the use of a Display Installation Checkout Page 3-23 Revision G

84 3.8.7 PED Check The NGT-2000/-2500 may be interfaced to a compatible PED (i.e. Tablet or Smartphone). The PED interface requires that a WiFi Serial Adapter be connected to the wiring harness and the WiFi configuration option be set up. The PED requires a compatible APP. The PED and NGT-2000/-2500 WiFi interface must be configured. Refer to paragraph 3.4. A functional check with the NGT-2000/-2500 is accomplished during the check of the ADS-B In, TIS-B, FIS-B and any other checks requiring the use of a PED GPS Operation Check This check requires that the GPS antenna to be open to a clear sky or a GPS Simulator or repeater to generate the necessary signal. 1. From the Lynx MAT select Service Live Data GPS. 2. Cycle power to the NGT-1000/-2000/-2500 and allow the GPS to acquire the position Acquisition of signal can take up to 2 minutes. 3. Observe that the GPS data is being received and signal strength is within 30 to 50 db. Note The Navigation State always shows RAIM even though the device is actually in WAAS mode. See Figure If the GPS reception is a problem, check the following: The GPS signal may be blocked; move the aircraft to an open environment or input a GPS signal using test equipment. Check the GPS antenna or wiring for installation issues. Check that the L-Band and GPS antenna cables are not swapped. Check the fault log (Info Fault Log) for issues. Figure 3-18: Lynx MAT Live Data-GPS Page 3-24 Installation Checkout Revision G

85 4. Verify that the ADS-B Out Fail Lamp (if installed) is flashing until the position is available and then remains OFF indicating that the GPS position is computed by the Unit. If a CP-2500 Control Panel is installed the GPS INIT and ADS-B SYSTEM FAIL messages are removed from its display. 5. Verify that the GPS position agrees with a known reference point. 6. Verify that the Day, Month, and Year data is correct. 7. Verify that the signal Strength (C/No) of 30-50dB is displayed in the GPS signal strength for all the GPS/SBAS satellites in view. 8. Turn ON other avionics and verify that the signal Strength (C/No) of db is displayed in the GPS signal strength for the satellites do not degrade significantly and position remains steady. 9.

89 Section 4 Maintenance 4.1 INTRODUCTION This section contains general flightline maintenance and fault isolation procedures. Fault isolation is intended to aid in identifying and correcting invalidities or isolating failures to a defective assembly. 4.2 CONTINUED AIRWORTHINESS Regular maintenance of the NGT-1000/-2000/-2500 is not required except as included in this section and is to be maintained on a Condition Monitored basis. Condition monitoring is based upon the following: Visual observation by the user. All units have unlimited service life, where service life is defined as that point in time when repair is no longer economical Periodic Maintenance Perform the following at regular aircraft inspection intervals: Visually inspect for signs of corrosion. Visually inspect for condition of wiring, shield terminations for proper grounding, routing, and attachment/clamping. Check the security of the mounting hardware. It is recommended that an electrical bond check be performed between the unit and nearby exposed portion of the aircraft metallic structure and verify that the measured value is less than or equal to 2.5 milliohms. In the event of bonding check failure, remove the unit and clean it and its mounting holes at both the unit and the aircraft structure and reattach the unit. Re-verify the resistance between the unit and nearby exposed portion of aircraft metallic structure, and ensure it is less than or equal to 2.5 milliohms Maintenance Page 4-1 Revision G

90 4.3 FAULT ISOLATION Use the troubleshooting help provided in Table 4-1 for initial installations and debugging issues that may appear during operation. Use Table 4-1 to view observed failures or conditions and possible cause and corrective actions. The symptoms listed are for all the possible equipment installations. It is up to the user to identify their particular installation. Failures are typically observed via the indicator lamps (ADS-B Out Fail and No ADS-B Coverage) or through messages displayed on the control panel or display screens depending on the particular installation. A MPC connected to the USB port of the NGT-1000/-2000/-2500 is essential in troubleshooting. Refer to paragraph and Table 4-2 for instructions on viewing fault logs and using the service functions of the Lynx MAT. The information provided here should be in conjunction with the information provided in Table 4-1. In addition, devices connected to the NGT-1000/2000/2500, such as a control panel or display can be useful for determining whether the NGT-1000/-2000/-2500 is functioning properly or if there are problems with the installation. NOTE The information listed in the Symptoms column encompass many of the possible issues that a technician may observe, but only some of the items may actually be seen depending on the model and the installation of optional equipment. If the CP-2500 is not installed, a locked standby/operate switch must also be installed. It should be noted that the ADS-B Out Fail Lamp is ON when the unit is in maintenance mode (via the Lynx MAT) or if the control panel or transmit switch is set to Standby. If the only corrective action left is to contact L-3 Field Service, then L-3 Field service personnel may request that a file be created using the MPC that would provide them with information on the unit (i.e. version, faults, and configuration). Create this file by going to the File menu of the Lynx MAT, selecting Save, and placing the file in a location that can be easily located for transfer to L-3 Field Service FieldService.Avionics@l-3com.com.

If GTX-327 or 330 is installed, verify that the RS-232 output is set to "REMOTE". 4. Verify correct wiring to the standby/operate switch. The switch needs to be wired to ground (operate) for the unit to transmit, 5. Connect to MAT and view fault logs and status screens to troubleshoot cause of the failure. Replacement of the unit may be required. Contact L-3 Field Service before removal of the unit Maintenance Page 4-3 Revision G

92 Table 4-1: Troubleshooting SYMPTOMS ADS-B Out Fail lamp and No ADS-B Coverage lamp (NGT- 2000/-2500 only) are ON. If installed, CP-2500 indicates ADS-B SYSTEM FAIL. The ADS-B Out Fail lamp Flashes (slow rate) for 120 seconds and then remains ON. (NGT-2000/-2500 only) The No ADS-B Coverage lamp is illuminated. (NGT-2000/-2500 only) Traffic (STIF) displays indicate "DATA-FAIL" and WI-FI information is not available. NOTE: If the traffic (STIF) display is in Standby mode, then that is an indication that GPS signal was available at least once during this power cycle, but has been lost. CP-2500 displays "GPS-INIT" for 2 minutes, followed by "ADS-B SYSTEM FAIL". The No ADS-B Coverage lamp stays illuminated. Note: No ADS-B Coverage lamp remains illuminated even when testing with an IFR Displays Normal operation. CP-2500 displays No ADS-B Coverage. CAUSE / CORRECTIVE ACTIONS 1. Verify standby/operate switch is set to operate. If a CP-2500 is installed, verify mode set to "ALT". ( SBY mode on the CP-2500 indicates "FAIL" of the unit to indicate that it is not transmitting). 2. Check the fault log and live signals with the MPC. Failure can also be caused by loss of control panel signal to the NGT-1000/-2000/ NOTE: If CP-2500 is installed, verify it is turned on. If using a GTX-327/330, verify it is turned on. 3. Replacement of the unit may be required. Contact L-3 Field Service before removal of the unit. GPS attempts to acquire for 2 minutes, and then a FAIL indication shown (fail lamp, etc). This indicates that the GPS cannot acquire a position: 1. Verify correct wiring of the GPS antenna. Verify that the GPS and L-band antenna cables are not swapped. 2. If inside a hangar, verify GPS repeater is operational and is within line of site of the aircraft GPS antenna. 3. If outside the hangar, verify the GPS antenna has a clear view of the sky. 4. Connect the MAT and verify fault logs and check for GPS reception status. Signal strengths should be between 30-50db to be usable. 5. Remove the GPS antenna connector from the unit, and verify that approx +12 VDC is available at the center pin of the GPS connector of the unit. 6. Remove power from other broadcasting equipment and wait 2 minutes for the GPS to acquire a signal. Replacement of the unit may be required. Contact L-3 Field Service before removal of the unit. (NGT-2000/-2500 only) A ground station is not being detected by the unit. 1. Aircraft may not be within range of a local ground station. 2. If No ADS-B Coverage lamp continues to remain illuminated even when airborne within range of a ground station, check the lamp wiring for proper connection to the unit. 3. Replacement of the unit may be required. Contact L-3 Field Service before removal of the unit. NOTE When crossing boundaries between ground station coverage areas, out of coverage indications are possible. Page 4-4 Maintenance Revision G

93 Table 4-1: Troubleshooting SYMPTOMS The ADS-B Out Fail lamp flashes (fast rate). (NGT-2000/-2500 only) Displays Normal operation. CP-2500 displays CODE MISMATCH -CHECK TRANSPONDER". Note: This does not apply if using GTX-327/330 as a control panel, as there cannot be a mismatch. CAUSE / CORRECTIVE ACTIONS The unit cannot detect a mode "A" code being transmitted from the transponder. 1. Transponder is not powered or is in Standby (STB) mode. The transponder must be in ALT or ON mode to remove this message. 2. Transponder antenna and the L-band antenna (for UAT operation) are located too far apart so that the unit cannot detect the transmitted Mode A Code from the transponder. Refer to the installation section for the chart for maximum distance between antennas. 3. Replacement of the unit may be required. Contact L-3 Field Service before removal of the unit. NOTE Occasional mismatch detections may occur due to interference conditions. However, flashing should not be continuous when matching Mode A code is present. The ADS-B Out Fail lamp flashes (fast rate). (NGT-2000/-2500 only) Displays Normal operation. CP-2500 displays CODE MISMATCH - PUSH TO ACCEPT XXXX. Note: This does not apply if using GTX-327/330 as the control panel; as there cannot be a mismatch. Lamps - Normal operation. Traffic (STIF) displays continues to show "DATA- FAIL" even though no ADS-B Out Fail lamp or message is indicated. CP Normal operation. Lamps - Normal operation. Traffic symbols on the Traffic display are open diamonds and not directional traffic (arrowheads or triangles). CP Normal operation. The unit is detecting a different code selected in the transponder from the code entered into the CP Press the small knob on the CP-2500 to change it to the same squawk code as the selection set in the CP Or, alternately, change the squawk code in the transponder to match the code entered into the CP (NGT-2000/-2500 only) Display is not receiving 429 STIF data. Normal operation is that "DATA-FAIL" is displayed until GPS is acquired, and then the STIF display should indicate Standby mode. 1. Verify DCM and display are configured for STIF traffic and the correct speed. The unit emulates L-3 Avionics System SKY497 format. This is a high speed 429 bus. Consult display manufacturer's installation manual for proper set-up procedures. 2. Replacement of the unit may be required. Contact L-3 Field Service before removal of the unit. (NGT-2000/-2500 only) This is normal for all STIF displays. Directional symbology can only be displayed on a DTIF display. 1. The traffic display does not support the DTIF format necessary to show directional data provided by ADS-B. 2. The directional information that is being received by the unit does not have directional data. The unit continues to transmit non-directional data to the traffic display Maintenance Page 4-5 Revision G

94 Table 4-1: Troubleshooting SYMPTOMS ADS-B Out Fail lamp is OFF, and no other fail indications are showing. The No ADS-B Coverage lamp is ON unless the aircraft is receiving an actual ground station. Use of the IFR-6000 does NOT extinguish the lamp. Traffic not appearing on the Traffic Displays and they indicate Standby mode. Also, no traffic showing on the WI-FI device while simulating ADS-B (UAT) traffic with a ramp tester such as the IFR CP Normal operation. Baro Altitude (Pressure altitude) is not being transmitted as indicated by the IFR-6000 in Monitor mode. Geometric altitude is being transmitted from the unit, and all other information is available. ADS-B Out Fail lamp is OFF. (NGT-2000/-2500 only) Display/PED Altitude information is shown as dashes. The CP-2500 altitude page displays "INVLD PA". CAUSE / CORRECTIVE ACTIONS (NGT-2000/-2500 only) The Traffic (STIF) displays revert to standby whenever the GPS groundspeed is below 7 knots. This speed assures a valid aircraft track for orientation of traffic on the displays. 1. Run Self Test on unit using the CP-2500, if available (instructions are located in installation checkout section). If 3-track traffic image does not appear, an open wire or other connection problem exists. If traffic does appear, the below override setting should be observed. 2. Place the unit in ground test mode using the MAT tool. This screen gives the technician the option to simulate a groundspeed value of 10 knots and also the aircraft heading. NOTE: Once in Ground test mode with a ground speed of 10 knots, the STIF displays should automatically switch to Operate mode. 3. Certain software versions of the IFR-6000 may inhibit traffic if the vertical rate on the simulated target is set to "LEVEL". It is recommended to set the simulated targets to either climbing or descending targets. Note - This issue has been resolved on the IFR-6000 Version and later. Either the unit is not receiving BARO-ALT (Pressure altitude), or the control panel is set to ON mode. 1. Verify that the GTX-327/330, or CP-2500 is set to ALT Mode. 2. Verify that the unit is receiving BARO-ALT (Pressure altitude). If a CP-2500 is being used it can be viewed by going to the Altitude page. The page should display the altitude for example as: 800PA (for 800 ft pressure altitude). In the case of missing altitude, it displays "INVLD PA". Pressure altitude is a required output for FAA compliance. In the event of the loss of Pressure altitude, the UAT device continues to operate by reverting to GPS altitude as a back-up. The GPS altitude can be viewed with the MAT device. NOTE Some altitude encoders can take 1-3 minutes to output data. Page 4-6 Maintenance Revision G

95 Table 4-1: Troubleshooting SYMPTOMS Lamps - Normal operation. No traffic or weather information is being displayed on the PED over WI-FI. CP Normal operation. Lamps - Normal operation. FIS-B weather (such as METARS, NEXRAD, CONUS Data) is not being seen on the weather displays. CP Normal operation. Cannot connect to the unit with the MPC/MAT tool. Lamps - Normal operation. CP Normal operation. (NGT-2000/-2500 only) Displays - Normal operation. The four digit squawk code is missing from the ALT and ON screen of the CP The ADS-B Out Fail lamp Flashes (slow rate) for seconds and then remains ON. Note: Code appears OK in SBY mode. CAUSE / CORRECTIVE ACTIONS (NGT-2000/-2500 only) 1. Verify WI-FI module is receiving data from the unit. For example, on the RN-370M models, this is indicated from visually seeing the blue flashing light on the unit. If indicator light is not flashing, verify WI-FI is configured properly in the DCM settings. Also verify the device has power (batteries) and that the connections between the WI-FI module and the unit are correct. 2. If WI-FI module is indicating it is receiving data, verify that the PED Wi-Fi connection is configured to receive the correct device name. (I.E. "WI-FLY-100"). 3. Verify PED App is compatible with the unit. 4. Verify the configuration setting for the PED App being used. 5. Replacement of the unit may be required. Contact L-3 Field Service before removal of the unit. (NGT-2000/-2500 only) Ground testing with the IFR-6000 can only simulate textural data such as METARS. 1. When used in flight, the aircraft must be within range of a ground station No OUT OF COVERAGE message (CP-2500) or No ADS-B Coverage lamp is OFF. NEXRAD information is only transmitted every 5 minutes, and CONUS information is only available from certain ground stations, and is only transmitted every 15 minutes. 1. The USB connection to the unit requires special drivers that must be installed on the MPC being used (see the general information section for details). If that has been successfully accomplished, replacement of the unit may be required. Contact L-3 Field Service before removal of the unit. 2. Verify that the MAT being used is compatible with the software in the unit being serviced. Contact L-3 Field service for more information. This is an indication that the Lynx MSS has failed and may also be seen if the aircraft is in the hanger with no GPS signal for > 2 minutes. 1) Move the aircraft into an area with access to a GPS signal. 2) Cycle power to the Lynx MSS. 3) Replacement of the Lynx MSS or system component may be required. Contact L-3 Field Service before removal of the unit Maintenance Page 4-7 Revision G

96 4.4 USING THE MAINTENANCE PC The Maintenance PC (MPC) and Lynx Maintenance Application Tool (Lynx MAT) are used to interface with the NGT-1000/-2000/-2500 to load software/firmware/, view factory / version data, retrieve fault logs, data recording, and simulating live data. NOTE The screen information for Lynx MAT is very similar between the NGT- 1000, NGT-2000, and NGT Differences in appearance are either noted or will be shown in the following procedures. These procedures assume the following: Power is being supplied to the NGT-1000/-2000/-2500 and system components (i.e. antenna, display, and controllers). The correct Lynx MAT software is being used to load software. See the General Information section (Software Versions) for software details. The software to be loaded is available on the MPC being used. The Lynx MAT is active on the MPC. The MPC is connected to the unit via the USB interface The MPC and unit are communicating.
