Communications for the control of the remote transponder are by one-way ARINC 429 bus. If the transponder is part of a TCAS installation, two-way communications by ARINC 429 data bus are also utilized between the transponder and the TCAS. The transponder will perform normal Air Traffic Control (ATC) functions whether it is or is not part of the TCAS system; however the TCAS system cannot function without the transponder. Antenna diversity operation of the transponder is a requirement for TCAS installations. The transponder is capable of accepting altitude (air data) information from a variety of optional sources. These include the ARINC 575 and ARINC 706 Air Data Computers. Furthermore, selection between a primary and secondary input for each of these sources is provided. An input and output ARINC 429 Maintenance Interface is provided that conforms to ARINC 604 and OEM specific requirements. The transponder may also receive ARINC 429 data from a variety of equipment (i.e. Inertial Reference System

(FMS), Data Concentrator, Flight Management Computer (FMC)/Global Navigation Satellite System (GNSS), FMC Gen, Flight Control Computer (FCC)/Maintenance Computer Program (MCP), Control Head, and Air Data System (ADS)). This data will be utilized to populate:

Therefore, the XPDR transponder marking for TSO-C112e is Level 2adens, Class 1. exceeds the minimum output power level of 125 watts required by Class A1 transmit only equipment as defined in RTCA/DO-260B. Therefore, the XPDR transponder marking for TSO-C166b is Class A1 transmit only. ______________________________________________________________________________ Page 42 Copyright Leonardo Finmeccanica S.p.A. All rights reserved UNCLASSIFIED UNCLASSIFIED MAN-1124/01 T02 ___________________________________________________________________________________________________________ 5.1.1 ATCRBS System Operation The ATCRBS system can be defined as a secondary surveillance radar system developed for use within the air traffic control system for more precise position reporting of planes. It is used in conjunction with the primary radar, which is used to determine the presence of planes in the airspace. ATCRBS supplements this positional information with positive identification and altitude information allowing controllers to track each plane more precisely and efficiently .1 In this scenario the ATC ground based interrogator transmits an interrogation by means of sequence of pulses at a frequency of 1030 MHz and call all transponders for a response on the mode being used to reply. The received replies will be displayed on the ATC radar screen. Analog to the ground based interrogator, an airborne TCAS device may transmits interrogation for airborne traffic. TCAS can detects direction and altitude of an aircraft equipped with a transponder. Figure 5-1 ATCRBS System 1"The Story of Mode S: An Air Traffic Control Data-Link Technology" (Emily Chang, Roger Hu, Danny Lai, Richard Li, Quincy Scott, Tina Tyan) ______________________________________________________________________________ Page 43 Copyright Leonardo Finmeccanica S.p.A. All rights reserved UNCLASSIFIED UNCLASSIFIED MAN-1124/01 T02 ___________________________________________________________________________________________________________ 5.1.2 ATCRBS Transmission Overview The Air Traffic Control Radar Beacon System (ATCRBS) interrogates aircraft with either Mode A or Mode C. The Mode A interrogation requests the aircraft identification code. The Mode C interrogation requests the aircraft altitude. Any aircraft in the beam of the radar replies. In order to prevent an undesired reply from an aircraft which are not in the main beam the Side Lobe Suppression (SLS) technique is used. Looking at the radius antenna diagram, leaking signals (called side lobes), can be identified as interrogation by aircrafts which are not the desired targets. The interrogation represented in Figure 5-2 would has multiplies replies from Target 1, 2 and 3. The interrogation represented in Figure 5-3 will receive a reply from Target 1 according to the following diagram:

All rights reserved UNCLASSIFIED UNCLASSIFIED MAN-1124/01 T02 ___________________________________________________________________________________________________________ 5.1.3 OVERVIEW OF MODE S Mode Select (Mode S) is a combined secondary surveillance radar beacon system with ground-

air-ground and air-air data link capability. It includes a 24-bit aircraft technical address which provides more than 16 million unique addresses, allowing the interrogator to select then interrogate a specific aircraft of interest. Each discrete interrogation contains the unique address of the aircraft for which it is intended and elicits a response dependent upon the level of capability of the corresponding transponder. Civil aircraft have a permanently assigned technical address. Implementation of a Mode S interrogation capability improve the existing systems in the following ways:

Aircraft state (heading, speed, etc.) and aircraft intent information is available via Mode S selective interrogations. Adaptive re-interrogation will significantly improve the probability of detecting an aircraft that is in a marginal signal condition. The Mode S signal structure will provide improved error detection and correction. More than sixteen million transponder addresses will allow unique identification of all Refined range and position accuracy is made possible via Mode S GPS squitter and/or aircraft. Mode S datalink. 5.1.3.1 Signal Characteristics Mode S is fully backwards compatible with the existing Air Traffic Control Radar Beacon System

(ATCRBS). Mode S transponders respond to Mode S interrogations. Mode S interrogators can interrogate ATCRBS or Mode S transponders. Both systems use the same interrogation and reply frequencies (1030 MHz and 1090 MHz, respectively). ______________________________________________________________________________ Page 46 Copyright Leonardo Finmeccanica S.p.A. All rights reserved UNCLASSIFIED UNCLASSIFIED MAN-1124/01 T02 ___________________________________________________________________________________________________________ Mode S-only interrogations use binary differential phase shift keying modulation (DPSK) at 4 MB/sec and Mode S replies have binary pulse position modulation (PPM) at 1 MB/sec. The Mode S coding structure provides enhanced error detection and correction (less than 1 undetected error in 108 messages). Mode S is not secure or jam-resistant and is not intended to replace the encrypted military Mode 4. Mode S has two basic message lengths: 56 bits and 112 bits. The 56 bit surveillance formats include a 32 bit command field and a 24 bit address field. The 112 bits communication formats include a 32 bit command field, a 56 bit data field and a 24 bit address field. The 112 bit extended length message formats include an 8 bit command field, an 80 bit data field and a 24 bit address field. Interrogation Process 5.1.3.2 Fully operational Mode S interrogators or clusters of interrogators are allocated on interrogator identification (II) code which, in conjunction with the unique aircraft technical address, enables linking between the interrogator and the aircraft of interest. All-call interrogations are sent to all aircraft in a region to obtain the corresponding 24-bit technical addresses. These addresses are maintained in an internal database and, once the address is obtained, the all-call acquisition doesnt need to be repeated for that aircraft. Upon receiving the technical address, the interrogator sends a lockout message to inhibit the corresponding transponder form replying to further Mode S all-call interrogations from any sensor with that interrogator identification code. Lockout is refreshed each antenna scan as part of the normal surveillance protocol and time-out occurs in 18 seconds if no further lockout commands are received. The interrogator also has the provision (lockout override) to command a transponder to respond regardless of the lockout status effect. Once it has the unique transponder address, the interrogator can selectively interrogate to obtain altitude and Mode 3/A codes for Mode S to Mark XII correlation or other useful information. ______________________________________________________________________________ Page 47 Copyright Leonardo Finmeccanica S.p.A.

It is possible that such a train of pulses would give rise to multiple SSR bracket detections which could overload the plot extractor and effect its proper operation. It is advisable that an SSR plot extractor design should anticipate the introduction of Mode S and include circuitry to provide protection against Mode S replies. In order to detect a Mode S reply it is only necessary to detect the four Mode S preamble pulses. These pulses are detected as follows:

a second pulse leading edge occurs 7-9 clock periods after detection of the first pulse leading edge;

a third pulse leading edge occurs 28-30 clock periods after detection of the first pulse leading edge;

a fourth pulse leading edge occurs 36-38 clock periods after detection of the first pulse leading edge. The detection of a Mode S preamble should suppress bracket detection for a period of 120 s

(994 clock periods). After preamble detection the train of pulse leading edges should be monitored for a gap of at least 22 clock periods. Such a gap would exceed that which is possible in a Mode S reply and would indicate that the preamble had been spurious, possibly owing to chance overlapping fruit replies. If a gap of that size is detected, the bracket detection suppression should be released so that SSR reply processing can resume. Preamble 8.0 S 3.5 4.5 Time (S) 0.0 0.5 1.0 Example.

Furthermore the fault location can be performed even on the Transponder itself in order to identify the failed module. The TRA-100B Transponder provides a Built-In-Test function strictly for the purpose of annunciation to the crew of a faulty Transponder system and for the purpose of providing maintenance information for the repair function. The TRA-100B provides several Input/Output interfaces for Built-In-Test capability necessary to perform a diagnostic process to isolate the failure and provide the information related to its location. 7.2 FAILURE DATA STRUCTURE The diagnostic results are stored in a NVM in accordance with the following data::

a) b) c) d) One Hundred (100) Flight legs of storage. Ten (10) subassembly and external faults per flight segment. Three (3) subassembly faults for ground tests. Two Hundred Thirty (230) bytes of storage per Current Flight leg and One Hundred Sixty Seven (167) bytes for each other Flight leg segment. 7.2.1 Flight Information Header For each flight leg, currently available flight information is stored in a fixed header. The flight leg is incremented upon reception from the CFDS of a command label with code of 2, which occurs during the aircraft take-off. From one take-off point to the next, faults is stored for the 'current' flight leg. The flight information header records all the data received on the maintenance port for each flight leg with the exception of GMT, and flight phase as per the following table:

The flight information header records all the data received on the maintenance port for each flight leg with the exception of GMT, and flight phase as per the following table:

LED on the front panel of the TRA-100B transponder illuminate when TRA-100B system failures are detected (Figure 7-3). The TRA-100B transponder's Built-In-Test equipment (BITE) continually monitors the equipment

(both internal and external sources) and if a failure is detected will cause the transponder lamp. System failure indications displayed on the front of the transponder are detected during Functional-Self-Test. The Functional-Self-Test is manually initiated from the TEST pushbutton on the front of the transponder. Some of the transponder faults, are indicated with red LED's on the transponder front panel. The following is a list of the transponder fault LED's. During Power-Up the XPNDR red LED is set and remain set until the equipment is initialized (i.e. Software and Firmware started up). The XPNDR red LED is set while the failure discrete output pins are in the active state. The XPNDR green LED is set to indicate that the equipment is initialized (i.e., Software and Firmware started up) and the failure discrete output pins are not in the active state. The front panel LED's provide a real time report of the validity of the Transponder internally and the external interfaces. The LED's are activated by the Test Push-button. The tests for the "on-ground" condition are performed at the time of the activation of the test push-button. The data from this self-test and the data from the latest passive test sequence is then displayed by the LED's in the following manner:

Within 1 second from the time the push-button is activated, NOGO (RED) and external interfaces LED's is turned on for 3 seconds. NOGO (RED) and external interfaces LED's then go off for 3 seconds. The appropriate LED then is set on and stays lit until the push-button is released. The appropriate LED above is green for the Transponder, if no internal faults are identified, and red for the Transponder, if any internal fault is identified. The test cycle that is initiated by the push-button re-runs after the 3 second, 3 second, 3 second sequence described above is completed, if the push-button is still active. ______________________________________________________________________________ Page 57 Copyright Leonardo Finmeccanica S.p.A.

It starts with a visual inspection of the Transponder to verify eventual damage that can be occurred during the handling, packaging and/or transportation. In case of damage the maintainer has to verify if it is reported on the Failure Report supplied with the Equipment. In case of missing information the maintainer shall record the damage updating the Failure Report. Therefore the equipment shall be connected to the STTE (see Figure 7-1) and shall verify the data reported in the NVM (see Figure 7-7). The STTE provides the necessary supplies, command and control signals and maintenance interface. The first information on the Transponder health status is provided by the Front Panel. The TRA-

100B is equipped with a set of LED which provide the status of the Transponder itself and the status of the Transponder interfaces. Figure 7-3 TRA-100B - Front Panel LED ______________________________________________________________________________ Page 70 Copyright Leonardo Finmeccanica S.p.A. All rights reserved UNCLASSIFIED UNCLASSIFIED MAN-1124/01 T02 ___________________________________________________________________________________________________________ As showed in Figure 7-3 the following LED are present on the Front Panel with the following meaning:

The NOGO (RED) LED is set while the failure discrete output pins are in the active state. The GO (GREEN) LED is set to indicate that the equipment is initialized (i.e., Software and Firmware started up) and the failure discrete output pins are not in the active state. The front panel LED's provide a real time report of the validity of the Transponder internally and the external interfaces. The LED's are activated by the Test Push-button. The tests for the "on-ground" condition are performed at the time of the activation of the test push-button. The data from this self-test and the data from the latest passive test sequence is then displayed by the LED's in the following manner:

______________________________________________________________________________ Page 71 Copyright Leonardo Finmeccanica S.p.A. All rights reserved UNCLASSIFIED UNCLASSIFIED MAN-1124/01 T02 ___________________________________________________________________________________________________________ Within 1 second from the time the push-button is activated, NOGO (RED) and external interfaces LED's is turned on for 3 seconds. NOGO (RED) and external interfaces LED's then go off for 3 seconds. The appropriate LED then is set on and stays lit until the push-button is released. The appropriate LED above is green for the Transponder, if no internal faults are identified, and red for the Transponder, if any internal fault is identified. The test cycle that is initiated by the push-button re-runs after the 3 second, 3 second, 3 second sequence described above is completed, if the push-button is still active. However, the LEDs remains in their status annunciation state, and will change in response to any new array of fault data picked up by the latest test cycle. 7.4.3 Connection procedure The procedure to connect the TRA-100B to the STTE is following reported (ref. Figure 7-1):

1. Install the TRA-100B into the mounting tray (pos. 6 and 7) and push it until the rear connectors are mated. Securing the TRA-100B to the mounting tray using the two hold down screws Connect the Ethernet connector Connect the Test connector. 2. 3. 4. 7.4.4 Fault Finding The TRA-100B stores the failures occurred during the operation in the NVM. Nevertheless if a failure arise in a section of DPIO the Transponder is not operative and the NVM content cannot be read. The procedure to perform the fault finding on TRA-100B is following reported:

1. Verify the status of the front panel LED. 2. If the red LED NO GO is on the DPIO SRU is failed but no data cannot be written in the NVM. Therefore follows the procedure for DPIO Removal (Ref. 8.4.1). 3. If the green LED GO is on, the TRA-100B is able to perform the auto test phase. After 30 sec. the results of test will be reported in the NVM Maintenance Interface box (see Figure 7-7) 4. The data are organized as follows:

a. Current Flight Information data pack: This field contains data related to flight information such as departure location (From), arrival location (to), flight number

This checkout consist mainly in running the ATP procedure as described following:

7.4.5.1 Check of lightning protection devices presence The testing in this section consists of applying an AC voltage through a current-limit resistor to the UUT rear connector discrete pins. The voltage level has been selected to provide enough current to activate the transzorbs. With this AC voltage applied, the Minimum and Maximum DC voltage levels on discrete output pins are measured to ensure that the transzorbs perform voltage clamping at the device rated values. Care is taken to apply the AC voltage for less than 15 seconds in order to prevent damage to the discrete output circuit in case of a transzorb failure. The following table defines the series resistor value, the external AC voltage to be used for each single pin and the expected clamping voltage to be verified. ______________________________________________________________________________ Page 73 Copyright Leonardo Finmeccanica S.p.A.
