OPERATION
5.1 TRA-100B MODE S TRANSPONDER – MODES OPERATION
The basic XPDR System consists of a transponder, a control unit, two antennas, and installation
hardware. 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 (IRS)/Flight Management 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:



Flight Identification required for Elementary Surveillance
Downlink Aircraft Parameters required for Enhanced Surveillance
ADS-B Extended Squitters.
The XPDR performs its intended function and not create a hazard to users of the National
Airspace System (NAS).
The Transponder TRA-100B is a avionics equipment capable to provide the Mode S Transponder
function required by Technical Standard Order (ETSO-C112d/TSO-C112e).
It also provides Extended Squitter ADS-B Out function required by ETSO-C166b/TSO-C166b.

___________________________________________________________________________________________________________
The TRA-100B is designed to be a Level 2 transponder.
For Level 1 includes the following capabilities:
 Mode A identity and Mode C pressure-altitude reporting,
 Air Traffic Control Radar Beacon System (ATCRBS)/Mode-S and Mode S all-call
transactions,
 Addressed surveillance altitude and identity transaction,
 Lockout protocols,
 Basic data protocols except data link capability reporting, and
 Air-to-air service and squitter transactions.
For Level 2 includes the following capabilities:
 Bi-directional air-to-air information exchange
 Ground-to-air data uplink, Comm-A
 Air-to-ground data downlink, Comm-B
 Multisite message protocol
 Data link capability reporting
 Aircraft identification reporting
 Traffic Alert and Collision Avoidance System (TCAS)/Airborne Collision Avoidance System
(ACAS) crosslink capability
Furthermore the TRA-100B contains the following optional additional features (associated ID code
for transponder marking):
 TCAS Compatibility (a)
 Antenna Diversity (d)
 Extended Squitter (e)
 Enhanced Surveillance (including Elementary Surveillance) (n)
 Surveillance Identifier Code (s)
Among the above characteristics, the Transponder TRA-100B:

exceeds the minimum output power level of 125 watts required by Class 1 equipment as
defined in RTCA/DO-181E. 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.

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.

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:

5.1.3
OVERVIEW OF MODE S
Mode Select (Mode S) is a combined secondary surveillance radar beacon system with groundair-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
aircraft.

Refined range and position accuracy is made possible via Mode S GPS squitter and/or
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).

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.
5.1.3.2
Interrogation Process
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 doesn’t 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.

The mode S reply consist of a long train of 0.5 s and 1.0 s pulses lasting for up to 130 s. 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.

FAULT ISOLATION
7.1 GENERAL
Fault Location procedure allows the maintainer to isolate the failure the source of a failure at the
system level or aircraft wiring level. 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)
One Hundred (100) Flight legs of storage.
b)
Ten (10) subassembly and external faults per flight segment.
c)
Three (3) subassembly faults for ground tests.
d)
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:

7.3 FAILURE LOCATION ON AIRCRAFT
The Fault Location procedure permits to find out the origin of a undesired symptoms.
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.

OFF A/C Troubleshooting procedure
The OFF A/C troubleshooting procedure is performed in the Repair Station in order to identify or
confirm the failure of received equipment.
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 TRA100B is equipped with a set of LED which provide the status of the Transponder itself and the
status of the Transponder interfaces.

During Power-Up the NOGO (RED) LED is set and remain set until the equipment is initialized (i.e.
Software and Firmware started up).
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:

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.
2.
3.
4.
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.
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
(Flight Nr.), aircraft identification (Aircraft Id.) and date (Date)
b. Failure Localization data pack (flight): This field contains data related Failure code
as per plus time of occurrence (GMT), Flight Phase, Error Repetition Counter (Fail

5. After the completion of test cycle, the operator shall select “Diagnostic Procedure” from
Tool Menu (Figure 7-8)
6. The Diagnostic Procedure screen (Figure 7-9) shows the Fail Code information together
with Module affected and Fail Description. The last column of section “Page” reports the
CMM number of page where the maintenance procedure to be performed in order to
restore the Transponder is recalled.
7. Clicking on the number of page reported in this column, the “Maintenance” section of this
manual will be opened showing the maintenance task to be performed to replace the failed
module.
7.4.5
Checkout procedure
In order to verify if the maintenance procedure restored the TRA-100B to its operating conditions,
a checkout procedure has to be performed.
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.

b. Determine the minimum RF signal level required to produce 90% transponder reply
efficiency (MTL).
c. Verify that MTL is in the range -75dBm ± 3dB
d. Repeat steps a,b,c interrogating the transponder on Bottom antenna.
Note: the -78dBm is obtained from best sensitivity (-77dBm) + best cable loss (-1dB), -72dBm is obtained from worst
sensitivity (-69dBm) + worst cable loss (-3dB)
Step 2 Sensitivity @ Low Sensitivity
a. Interrogate the transponder with a standard Mode C ATCRBS/Mode S All-Call interrogation
on Top antenna at MTL+3dB.
b. Verify that the reply ratio is ≥ 99%.
c. Set Low_Sense Activate discrete to GND
d. Verify that the reply ratio is 0%.
e. Increase the level of the interrogation to MTL+9dB
f. Verify that the reply ratio is ≥ 99%.
g. Set Low_Sense Activate discrete to OPEN
Step 3 ATCRBS and ATCRBS/Mode S All-Call Dynamic Range
a. Interrogate the transponder with a standard Mode A interrogation at RF levels at the
following levels: MTL +3 dB, -60dBm, -50dBm, -40dBm, -30dBm, -22dBm
b. For each of the above levels determine reply ratio and verify that it is ≥ 99%.
c. Interrogate the transponder with a standard Mode C ATCRBS/Mode S All-Call interrogation
at RF levels at the following levels: MTL +3 dB, -60dBm, -50dBm, -40dBm, -30dBm, 22dBm
d. For each of the above levels determine reply ratio and verify that it is ≥ 99%.
Note: -22dBm is obtained from -21dBm considering the best antenna cable attenuation equal to 1dB
Step 4 Mode S Sensitivity
a. Interrogate the transponder with a Mode S Only All-Call interrogation at a standard rate
with PR=0.
b. Determine the minimum RF level to produce 90% proper reply efficiency (MTL).
c. Verify that MTL is in the range -76dBm ± 2dB
Note: the -78dBm is obtained from best sensitivity (-77dBm) + best cable loss (-1dB), -74dBm is obtained from worst
sensitivity (-71dBm) + worst cable loss (-3dB)
