1. INTRODUCTION TO THE COSPAS-SARSAT SYSTEM
A. The COSPAS-SARSAT* system
The purpose of the COSPAS-SARSAT satellite system is to detect and locate all distress signals transmitted
by aeronautical, maritime or land-based beacons, for the search and rescue organizations.
This program is the result of an international collaboration between the United States, Canada and France
on the one hand (SARSAT project), and Russia on the other hand (COSPAS project). These two projects
are fully compatible.
Since the first results were obtained several countries have joined the program. Other countries continue to
join the COSPAS-SARSAT system partners.
ELTA in relation with CNES (French National Space Agency) has developed the complete range of products
required for COSPAS-SARSAT system operation. Now ELTA is focusing in the design and production of
ELT’.
Following an in-depth study phase, ELTA has arrived at highly conclusive technical results. Experimental and
operational use of the "ground" equipment have proven this equipment's reliability and ease-of-use.
At the end of 2015 the total estimated Cospas-Sarsat beacon is about 2,000,000.
From 1982 (date of the official Cospas-Sarsat system entry to service) to end of 2015, at least 41,750
persons have been saved thanks to Cospas-Sarsat use.
B. System organization (Ref. Figure 1)
In the COSPAS-SARSAT system, space equipment is placed on board several satellites in low near-polar
orbit to capture transmissions from emergency transmitters and to retransmit these signals to specialized
ground stations called Local User Terminals (LUT). These ground stations determine the position of the
emergency transmitters and then retransmit the position data to the designated Mission Control Centers
(MCC). The MCCs in turn retransmit these data to the appropriate Rescue Coordination Centers (RCC) so
that they can start the search and rescue operations.

There are several advantages to using the 406 MHz frequency:
– Worldwide coverage: locating is not only possible in real-time within a radius of 2,500 km around the
station, but also in global mode outside this zone since the satellites memorize the messages on the
406 MHz frequency. Location process uses Doppler effect.
– Locating accuracy: 2 km as opposed to 10 to 15 km in the 121.5 MHz frequency. It should be noted
however that the 406 MHz beacons also transmit 121.5 MHz signal which enable the final approach of
the rescue teams in homing mode.
– Information reliability: the structure of the digital signal transmitted by these beacons makes it possible
to be sure that there is actually a distress situation, as well as to identify automatically the mobile in
distress which is vital for rescue operations.
– Unique identification: each beacon has it’s own identification information.
– Possibility to incorporate local Position data (GNSS) in the 406 MHz transmitted message
C. ELTA and the COSPAS-SARSAT system
(1) 406 MHz distress beacons:
These beacons transmit to the satellites a digital message which identifies them and gives their position,
as well as a signal that facilitates the final approach of the rescue teams.
They are suitable for all types of use (maritime, aeronautical and land) and can, depending on the model,
be activated manually or automatically. They are designed to function in the most extreme conditions with
a high degree of reliability.
(2) Low earth orbiting satellites:
At least four satellites are permanently operational. Since their orbit is near-polar, in the worst case every
point on Earth is overflown every two hours.
In a ground station's visibility zone, the satellites directly transmit the messages captured in that zone,
and also any messages from the zones not covered that they have stored in memory.
(3) Geo-stationary satellites are now available in the system and offer faster detection capability (close to 5
minutes) but require a GPS receiver to supply location that is sent via C/S message.
(4) Medium earth orbiting satellites:
In a very near future, such satellites will be added to Cospas-Sarsat System. They will improve the
Cospas-Sarsat performances and will allow the introduction of second generation ELT. They are not yet
operational.
(5)Ground reception stations:
The zone effectively covered (or visibility zone) is a circle with a radius of 2,500 km around the station.
These stations receive (via the satellites) and process:
• in real time, the messages from the beacons activated in their visibility zone and,
• in batch mode, the messages from the 406 MHz beacons activated outside that visibility zone and
memorized by the satellites.
Automatic processing of the 406 MHz digital messages allows the beacons to be located and the mobile
carrier to be identified.

2. GENERAL DETAILS OF THE ELiTe ELT
A. Purpose of the ELiTe ELT (Ref. Fig. 2)
With ELiTe ELT, ELTA proposes a new patented concept based on the supply of one unique Cospas-Sarsat
distress transmitter available for both Automatic Fixed and Survival ELT applications.
The ELiTe ELT is designed to transmit a digital distress signal to satellites that are part of the
COSPAS/SARSAT SYSTEM.
These satellites transmits the captured signal to the reception stations on the ground (LUT).
This signal is transmitted on the 406.040 MHz frequency and is used to precisely locate and identify the
ELiTe ELT.
It also transmits a 121.5 MHz signal to facilitate the final approach of the distress scene (final homing).
This ELT meets the latest ICAO and EOPS recommendations. It is ETSO C126b, ETSO C142a approuved.
Through the current EASA/FAA bilateral agreement it is automatically recognized as TSO C126b and TSO
C42a.
B. ELiTe ELT principle
ELiTe ELT principle is based on the association of the unique transmitter (ELiTe TRANSMITTER) and
dedicated mounting brackets (ELiTe AF-BRACKET or ELiTe S-BRACKET, or alternative storage and
transportation bag ELiTe S-Bag). It is this association that offers the final ELT type i.e. Automatic Fixed (AF)
or Survival (S).
The purpose of the ELiTe Coding Tag is to store on board the A/C the Cospas-Sarsat identification.
The Cospas-Sarsat Identification is memorized in an independent non-volatile memory located in this
dedicated passive wireless radio frequency device (very short range RFID technology).
This part is located on the ELiTe AF-BRACKET, or in ELiTe S-BRACKET or in ELiTe S-Bag, the alternative
storage and transportation bag of ELiTe S-BRACKET.
This part can be attached to the A/C structure by the mean of a metallic strap, when required.
It will keep, on board the A/C, the Cospas-Sarsat Identification code.
Upon any type of activation (automatic of manual) or after each self-test, ELiTe TRANSMITTER is acquiring
this relevant Cospas-Sarsat Identification Code and will use it to transmit the correct distress signal on
406.040 MHz.
The operator is then sure that any new ELiTe TRANSMITTER installed on/in its relevant bracket will transmit
the correct Cospas-Sarsat message upon it’s activation.
NOTE: Such wireless communication between ELiTe TRANSMITTER and ELiTe Coding Tag is a very short
range one, only few mm avoiding any risk of duplication/error.
NOTE: A copy of this Cospas-Sarsat ID code is made internally by ELiTe TRANSMITTER in non volatile
memory at each self-test or activation request allowing correct transmission even when the transmitter is
removed from its bracket (case of the Survival configuration) or in case of ELiTe Coding Tag access failure
(any type of ELiTe configuration).
During self-test process, the transmitter indicates the presence or absence of a valid ELiTe Coding Tag
content. Any change i.e. new ELiTe Coding Tag, (so new Cospas-Sarsat ID code) is detected.
If the ELiTe Coding Tag is absent or damaged (after the first installation correct reading), the transmitter will
use its internal copy for Cospas-Sarsat identification for the distress transmission (backup mode).
Documentation P/N: 15E64259 Rev A Page 15
Oct. 10/17
As a consequence when the transmitter is removed from its bracket it can transmit the relevant C/S ID (from
its internal backup memory).
Transmission will be made with the “last acquired” ELiTe Coding Tag content.
NOTE: When ELiTe TRANSMITTER is removed for maintenance or transportation it is important to put it in
the “OFF” mode avoiding any transmission (false alert possibility).
Valid Cospas-Sarsat Identification is indicated on the ELiTe Coding Tag label and is also displayed on the
ELiTe TRANSMITTER LCD display at each self-test or activation.
If the ELT ownership change, the ELiTe Coding Tag shall be re-coded in order to get a new unique 15 digit
Hex Code, with the appropriate new country code and new coding protocol as selected or required by the
country of the new final operator. Contact ELTA for additional details (www.elta.fr ) as necessary.
Coding of the ELiTe Coding Tag is realized using the dedicated ELiTe C/S ID ENCODER TOOL
P/N 17N23476 (see CMM 25-60-17 for detail) constituted of a PC software and RFID tag reader/writer USB
interface.
NOTE: In addition to the Cospas-Sarsat identification data, additional “configuration data” are stored inside
the nonvolatile memory of the ELiTe Coding Tag. As a consequence an ELiTe Coding Tag encoded for and
Automatic Fixed configuration shall not be used for Survival configuration and vice versa.
These “configuration data” are factory set at ELTA and cannot be modified by the dedicated
ELiTe C/S ID ENCODER TOOL P/N 17N23476 avoiding any wrong use of the intended ELiTe ELT
(Automatic Fixed or Survival).
C. ELiTe ELT Configurations
(1) ELiTe ELT in the AUTOMATIC FIXED CONFIGURATION
In this configuration, ELiTe is an Automatic Fixed Emergency Locator Transmitter (ELT) distress beacon.
ELiTe TRANSMITTER can be removed (example for maintenance) and ELiTe AF-BRACKET remains
installed and connected onboard the A/C (reliability improvement).
ELiTe TRANSMITTER gets the relevant COSPAS-SARSAT Identification from ELiTe Coding Tag located on
ELiTe AF-BRACKET.
In this Automatic Fixed (AF) configuration, It can be triggered manually (either from remote control panel
located in the cockpit or from ELiTe TRANSMITTER keypad) or automatically by means of an acceleration
sensor (G-switch, located on ELiTe AF-BRACKET) in accordance to EUROCAE ED-62A / RTCA DO-204A
standards.
Any encoding User, User Location and Standard Location protocols defined by Cospas/Sarsat can be used
in this configuration including country code assignation.
When ELiTe AF-BRACKET is connected to A/C +28 Vdc and A/C ARINC 429 Data Bus, it can receive the
A/C location (Latitude & Longitude). This information is then incorporated in the Cospas-Sarsat Identification
encoded as “Long”. Message location accuracy transmitted is truncated to 4’ of angle (about 5 Km) for User
Location protocol or 4” of angle (about 500 m) for Standard Location protocol as specified by Cospas-
Sarsat).
Basic User Protocols can be use with the Automatic Fixed configuration when there is no possibility to get
access to location data from the A/C.

(2) ELiTe ELT in the SURVIVAL CONFIGURATION
In Survival (S) configuration it can be triggered manually from ELiTe TRANSMITTER keypad in accordance
with EUROCAE ED-62A / RTCA DO-204A standards.
In addition ELiTe ELT proposes another mean of activation using a water sensor located on ELiTe
TRANSMITTER.
NOTE: It is not considered as “Automatic activation” per ICAO standard.
NOTE: This water sensor is inoperative in automatic fixed configurations.
Any encoding User Location or Standard Location protocols defined by COSPAS/SARSAT (C/S) can be
used in this configuration including country code assignation.
NOTE: Basic User protocols cannot be used with the Survival configuration as it not type approved by
Cospas-Sarsat.

(a) Standard solution using ELiTe S-BRACKET
In this configuration ELiTe is a Survival Emergency Locator Transmitter (ELT) distress beacon.
ELiTe TRANSMITTER can be removed (example for maintenance) and ELiTe S-BRACKET remains
installed onboard the A/C. There is no connection/wiring with the A/C in this configuration.
ELiTe TRANSMITTER gets the relevant COSPAS-SARSAT Identification from ELiTe Coding Tag stored and
located in an internal foam of ELiTe S-BRACKET.
ELiTe TRANSMITTER equipped with ELiTe Float shall be removed from ELiTe S-BRACKET for correct
distress signal transmission to Cospas-Sarsat satellite (not intended to remain in the bracket while activated)

(b) Alternative solution using ELiTe S-Bag
ELTA can propose an alternative Survival solution replacing the ELiTe S-BRACKET by ELiTe S-Bag.
Concept is similar (same materials), but there is no mean for A/C fixation and ELiTe S-Bag is equipped with
a Velcro strap allowing an easier transportation.
In this configuration ELiTe is a Survival Emergency Locator Transmitter (ELT) distress beacon.
ELiTe TRANSMITTER can be removed (example for maintenance) and ELiTe S-Bag may or may not remain
installed onboard the A/C. There is no connection/wiring with the A/C in this configuration.
ELiTe TRANSMITTER gets the relevant COSPAS-SARSAT Identification from ELiTe Coding Tag stored and
located in an internal foam of ELiTe S-Bag.
ELiTe TRANSMITTER equipped with ELiTe Float shall be removed from ELiTe S-Bag for correct distress
signal transmission to Cospas-Sarsat satellite (not intended to remain in the bag while activated).

(d) Radio-electrical characteristics
1 406 MHz satellite transmitter
– ITU Emission Type : 16K0G1D
– Frequency : 406.040 MHz,
– transmitter power : 5 W,
– modulation : "L" two-phase,
– transmission recurrence : 50 s +/- 2.5 s,
– transmission duration : 440 or 520 ms for Automatic Fixed configuration and 520 ms only for
Survival configuration.
– external antenna gain : 0 dBi.
2 Associated homing transmitter
– ITU Emission Type : 3K20A3X
– Frequency : 121.5 MHz,
– 121.5 MHz transmitter power : 160 mW (Automatic Fixed) & 180 mW (Survival),
– Modulation : AM , from, 1200 Hz to 400 Hz,
4 periods per second,
– External antenna gain : > 1 dBi.
(e)Environment characteristics
– Operating temperatures : -20°C to +55°C,
– Storage temperatures : -55°C to +85°C.
NOTE: Ambient temperature is recommended for ELT storage in order to lower the battery pack self-
discharge rate.
(f)Source of position data management (only applicable to Automatic Fixed configuration)
In this configuration ELiTe TRANSMITTER can potentially access two types of position data.
The primary one is issued from the A/C ARINC 429 data Bus (when present).
The second one (back up) is issued from its internal GNSS receiver that may become operational after
the crash (probable presence of big “holes” in the A/C structure allowing potential sky view).
Upon activation of ELiTe ELT, ELiTe TRANSMITTER is acquiring A/C position through the ARINC 429
(labels 310 & 311).
If this information is available, it incorporates this position in the transmitted Cospas-Sarsat distress
message (Long message, User Location or Standard Location Protocols as selected by the operator).
If not present at the date of activation, the default position value is encoded and transmitted in the
Cospas-Sarsat distress message.
When this information is lost (after the crash for example, ARINC 429 will stop its operation – no more
A/C power), ELiTe TRANSMITTER is waiting 20 minutes (lost confirmation delay) then activates its
internal GNSS for a maximum of 15 minutes trying to get a good quality position FIX.
Documentation P/N: 15E64259 Rev A Page 27
Oct. 10/17
As soon as the FIX issued from the internal GNSS receiver is achieved, It will replace the previous one
in the distress message.
If the FIX issued from the internal GNSS receiver is not achieved (or not enough good quality), ELiTe
TRANSMITTER will continue to transmit the previous position (from ARINC 429) for 4 hours in
accordance with Cospas-Sarsat specifications.
During the distress message transmission, the update of position data is performed in accordance with
Cospas-Sarsat specification (no more than one update every 5 minutes).
NOTE: Acquisition rate on ARINC 429 data bus is 200 ms for getting a complete Lat/Long information.
(g)Content of ELiTe Coding Tag
In this passive RFID tag two types of data are present:
– The Unique 15 Hex Cospas-Sarsat Identification Code composed of the following selected fields:
. Country Code,
. Message type,
. Protocol type,
. Detailed data relative to the selected protocol,
. 121.5 MHz Homing.
These parameters are selectable and can be set by ELTA, ELTA approved service center or ELTA
approved operators using the ELTA ELiTe C/S ID ENCODER tool P/N 17N23476 for Cospas-Sarsat
Identification management.
– ELiTe ELT Configuration selection:
. ELiTe ELT in Survival configuration (limited to Cospas-Sarsat User and Standard Location
Protocols, long messages),
. ELiTe ELT in Automatic Fixed configuration without access to A/C +28 Vdc and ARINC 429
(limited to Cospas-Sarsat User Protocols, short messages,
. ELiTe ELT in Automatic Fixed configuration with access to A/C +28 Vdc and ARINC 429 (limited to
Cospas-Sarsat User and Standard Location Protocols, long messages).
These parameters are selectable and can be set by ELTA, ELTA approved service center or ELTA
approved operators using the ELTA ELiTe C/S ID ENCODER tool P/N 17N23476. They define all the
internal configuration parameters allowing the correct operation of ELiTe TRANSMITTER as installed in
the relevant configuration. These parameters are fixed and cannot be modified by anyone (reserved for
ELTA factory setting).
– ELiTe Coding Tag A/C assignation
In addition to the above information i.e. Cospas-Sarsat Unique 15 Hex ID, factory setting configuration
parameters, we propose to add an item called “ELiTe Name” in the ELTA ELiTe C/S ID ENCODER tool
P/N 17N23476 allowing the operator to indicate on which A/C this ELiTe Coding Tag is intended to be
installed.
This information is indicated on one of the ELiTe Coding tag label and is also displayed on ELiTe
TRANSMITTER LCD along the Cospas-Sarsat 15 Hex as presented here under.
Definition of the content of this item “ELiTe Name” follows the following rules in order to provide the
means to identify the correct A/C assignation.
The “ELiTe Name” is composed of 6 fields as described below:
. Type of ELiTe : “AF” for Automatic Fixed or “S” for survival,
. One separator character ‘_ ‘,
. The Protocol Type : “U” for User or “UL” for User Location or “SL” for Standard Location,
. The Message Type: between to 1 to 4 for User protocols and between 1 to 3 for Standard ones,
. One separator character ‘_ ‘,

(3)ELiTe Automatic Fixed (AF) aircraft components
CAUTION :THE REMOTE CONTROL PANELS AND EXTERNAL ANTENNA ARE LISTED IN THE
COSPAS-SARSAT ELITE TAC # (C/S APPROVAL). USE OF OTHER PART NOT LISTED IN THE TAC
MAY REQUIRE ADDITIONAL COSPAS-SARSAT APPROVAL TESTS AND UPDATE OF CURRENT
TAC#. IT ALSO MAY CANCEL THE ETSO C126B GRANTED. CONTACT ELTA FOR ADDITIONAL
ASSISTANCE.
(a)Remote control panel
The remote control panel integrated in the aircraft cockpit usually consists of :
– a TEST/RESET pushbutton,
– an ELT ON indicator light,
– a two-position ON/ARMED switch with safety cover (flip guard). The safety cover forces the switch to
ARMED position. This switch must always remain in ARMED position, except in the case of manual
distress triggering.
The ELiTe Automatic Fixed ELT is integrated in the aircraft as far AFT as possible and so it must be
connected to the remote control panel. This remote control panel enables ELiTe TRANSMITTER
operation to be forced to ON (remote manual activation), to be tested (TEST), the distress transmission
stopped and restored in standby or ARMED mode (RESET) in the event of an untimely triggering of the
ELT, from the aircraft cockpit.
(b)External antenna
An external antenna is recommended to be installed on the fuselage of the aircraft to maximize
transmission of the distress signal to the satellites as required by ICAO.
The cable length should remain as short as possible in order to keep the connection RF losses lower
than 1.5 dB at each frequency (121.5 & 406.040 MHz) and to reduce the probability of cable damage
during and after the crash.

4. INSTALLATION OF THE ELiTe Automatic Fixed configuration
A. General
WARNING: ELITE TRANSMITTER CONTAINS NON RECHARGEABLE LITHIUM MANGANESE DIOXIDE
BATTERIES. IT SHALL NOT BE INSTALLED IN THE COCKPIT.
System security and reliability obviously depends on the standard of installation.
In order to ensure installation of the highest standard, the installation operations must be:
– performed in conformity with this document,
– performed in compliance with the current applicable regulations: CS, FAR or equivalent regulations
– performed by qualified personnel,
– performed so that :
. the aircraft's structural integrity is not affected,
. it will not hinder the pilot in normal position,
. it will not cause any damage in the event of an accident,
. it will not prevent or modify operation of the other safety systems.
If in doubt, contact the aircraft manufacturer or its representative,
. it will not degrade the ELiTe ELT performances described in DDP N° 16E24025 (Automatic Fixed),
– inspected by representative authority.
Special care should be taken in order to lower the risk of rupture of the RF cable between external antenna
and ELiTe AF-BRACKET due to vibration, shocks, flame.
B. Installation of ELiTe (AF) on the aircraft (Ref. Figure 11)
The ELiTe AF-BRACKET shall be installed as far AFT as possible in order to maximize the probability of ELT
survival in case of crash.
It Shall be installed on the primary structure of the A/C and shall not damp the crash sensor (G-Switch).
The G-Switch module DIRECTION OF FLIGHT must be parallel with the aircraft flight axis as indicated by
the G-Switch module's label. The G-Switch module direction and the A/C forward/aft directions must be
respected to ensure correct acceleration sensor (G.switch) operation (See Figure 11).
NOTE : An angle of up to ± 8° from the aircraft flight axis could be allowed.
An angle of up to ± 3° from the aircraft horizontal axis could be allowed.
Documentation P/N: 15E64259 Rev A Page 35

The fixation holes are part of ELiTe AF-BRACKET. Drilling pattern is the same as previous ADT 406 ELT.
The presented four possible solutions of G-Switch module on the top of the ELiTe AF-BRACKET are suitable
for A/C operation and are in accordance with EUROCAE ED-62A & RTCA DO-204A specifications.
These solutions will ease the installation of the ELiTe Automatic Fixed especially for retrofit application.
NOTE: The screens on display may be turned by 180° if required (through “maintenance” menu. Press at
the same time the “arrow” and “TEST or RESET” button on keypad and select the relevant control.
Validate by OK.
NOTE: For Helicopter installation the operator must verify with the local Airworthiness Authority for specific
installation instructions. Usually for the helicopter installation we recommend a 45° down inclination
(ELT G-Switch module direction indicated by “AIRCRAFT FRONT”) in order to take into account both axis X
(translation) and Z (vertical).
Attach the ELiTe AF-BRACKET to the fuselage of the aircraft by means of four M4 bolts in the four 5 mm
diameter holes at the corners of a 210 mm x 45 mm rectangle drilled in ELiTe AF-BRACKET. Particular care
must be taken with this attachment. Standard industry means must be used to lock the screws. Use flat
washer in order to avoid paint damage.
CAUTION : THIS ELT SHALL BE FIXED ON THE PRIMARY A/C STRUCTURE FOR CORRECT G-
SWITCH OPERATION DURING THE CRASH.
The Figure 13 shows the drilling pattern dimensions and determine the required area to access ELiTe
controls, connectors and space for ELiTe TRANSMITTER installation on ELiTe AF-BRACKET.

C. External antenna installation
ELTA recommend to use P/N 31908 (antenna model 2632-82 manufactured by COBHAM [formerly
CHELTON]) for high speed A/C or P/N 28592 (antenna model 1327-82 manufactured by CHELTON) for low
speed A/C.
Other external antenna may be used but some additional Cospas-Sarsat approval tests shall need to be
performed in order to amend the current Type Approval Number (TAC #). Contact ELTA or one of its
approved agents to check if the antenna can be used with this ELT model.
The external antenna must be installed on the upper part of the fuselage, as far AFT as possible.
Particular care must be taken with this attachment. Standard industry means must be used to lock the
screws.
The contact surface should be reinforced to prevent the antenna from tearing away at high speeds.
The cable used shall be of a high quality with very low losses.
RG 142 cable type, or equivalent, is recommended. ELTA recommends length lower than 2 meters lowering
the risk of rupture in case of crash. Cable RF losses shall remain lower than 1.5 dB.
When the coaxial cable is installed and the connectors mated, each end should have some slack in the
cable.
NOTE: FAA AC 43.13-1b recommends a minimum bend radius of 6 times the outer diameter of coaxial
cable.
The cable should be secured loosely to aircraft structures for support and protection.
Application of fire sleeves meeting the requirements of SAE AS1072 around the coaxial cable is
recommended.
Coaxial cable connecting the Antenna to the ELT Antenna installation should not cross aircraft production
breaks.
Connect the connector to the antenna and to the “external antenna. access” on ELiTe AF-BRACKET (BNC
connector).
D. Remote Control Panel installation
The ELiTe Automatic Fixed ELT can be remotely controlled by using a remote control panel installed in the
cockpit of the aircraft.
We are using “current loop” for the detection of the Remote Control Panel actions (toggle switch and push
button), so cable length of this link is not an issue. By experience cable up to 200 meters remains fully
operational and do not require grounded cable. This link requires 4 AWG 22 or AWG 24 wires.
The only limitation for this application is the DC current drained from the pin 6 (RCP_ALIM) of the ELiTe AF-
BRACKET CANON D-SUB 26 pin HD connector that shall remain lower than 15 mA.
Refers to Figure 14 for wiring details.

F. Installation and configuration of the ELiTe Automatic Fixed (Ref. Figure 14)
– Connect the external antenna cable to the ELiTe AF- BRACKET BNC connector,
– Switch the Remote Control ON/ARMED lockable toggle switch to "ARMED" on remote control panel,
– Connect the remote control unit cable to the ELiTe AF- BRACKET CANON D SUB connector and lock it,
– Connect the remote control unit cable rear of the remote control panel and lock it performed by qualified
personnel,
– Connect the A/C Data Bus & 28 Vdc (if present),
– Install ELiTe Coding Tag on its ELiTe AF-BRACKET location. This installation is mandatory for correct
ELiTe ELT operation.
After correct installation of the ELiTe Coding Tag, it shall be attached to the A/C by means of the metallic
strap in order to keep on board A/C the Cospas-Sarsat identification information related to the installed ELT.
So these information will remain in the A/C upon transmitter exchange (for overhaul process as example).
Install and fix ELiTe TRANSMITTER on ELiTe AF-BRACKET by means of the four captive screws applying
1.6 N.m torque on each with a 9/32 wrench. ELiTe TRANSMITTER will be switched to ARMED automatically
and will display the relevant C/S ID code read from ELiTe Coding Tag; the system is ready for use.
CAUTION : ON INITIAL INSTALLATION OR INTALLATION ON DIFFERENT ELITE AF-BRACKET IT IS
ESSENTIAL TO ENSURE THAT ELITE TRANSMITTER DISPLAYS A 15 HEX ID THAT
MATCHES THE HEX ID OF THE ATTACHED ELITE CODING TAG.
CAUTION : AS SOON AS THE BEACON IS IN ARMED POSITION IT CAN BE AUTOMATICALLY
ACTIVATED BY THE INTERNAL G-SWITCH.
5. INSTALLATION OF THE ELiTe Survival configuration

B. Installation of ELiTe (S) on the aircraft.
There is no special installation requirement.
Usually this type of Survival ELT is installed close to one exit door in order to allow easy access to cabin
crew in case of emergency evacuation.
For this type of use the ELiTe TRANSMITTER shall be equipped with ELiTe Float.
CAUTION : TRYING TO SLIDE ELITE FLOAT ON ELITE TRANSMITTER FROM TOP (INTERNAL
ANTENNA) TO BOTTOM (BATTERY PACK) WILL DAMAGE IT.
CAUTION : DO NOT PULL OR REMOVE THE LANYARD FROM THE FLOAT, THIS LANYARD SHALL
ONLY BE USES TO SECURE THE TRANSMITTER IN A DISTRESS CONDITION.
ELiTe Float shall be slide on ELiTe TRANSMITTER from bottom (Battery Pack) to top (internal antenna) and
is naturally locked on it (see Figure 15).
Figure 15
ELiTe Float Installation Process
When equipped in its final float position (see Figure 16) ELiTe TRANSMITTER can operate in various
conditions:
• Floating (like an EPIRB),
• Put on ground (like a PLB)
• Or insulated from any ground plane (held by a survivor).
NOTE: While floating the water sensor constituted by two screws of ELiTe TRANSMITTER is immerged
authorizing the additional water activation of ELiTe TRANSMITTER.
NOTE: The design of our water sensor require a complete immersion (DC current detection) for several
seconds, so moisture or non-permanent presence of water (splash) will not activate ELiTe TRANSMITTER.
NOTE: The water sensor is disable with the ELiTe TRANSMITTER is used in Automatic Fixed configuration.
Documentation P/N: 15E64259 Rev A Page 41
Oct. 10/17
Figure 16
ELiTe TRANSMITTER equipped with ELiTe Float
(1)Recommended installation
ELTA recommends using ELiTe S-BRACKET for such Survival configuration.
The fixation holes are part of ELiTe S-BRACKET. Drilling pattern is the same as previous ADT 406 S ELT.
NOTE: Lower internal ELiTe S-BRACKET foam (engraved with ELTA P/N 15P64038) can temporarily be
removed for easier metallic plate fixation.
Attach the ELiTe S-BRACKET in the A/C cabin of the aircraft by means of four M4 bolts through the four 5
mm diameter holes at the corners of a 210 mm x 45 mm rectangle drilled in ELiTe S-BRACKET. Particular
care must be taken with this attachment. Standard industry means must be used to lock the screws. Use flat
washer in order to avoid paint damage.
The Figure 17 shows the drilling pattern dimensions and determines the required area to access ELiTe
TRANSMITTER, ELiTe controls, and space for ELiTe S-BRACKET.
The overall volume for such installation is indicated in Figure 17

6. UTILIZATION OF THE ELITE ELT (Ref. Figure 20)
CAUTION : IN THE EVENT OF UNTIMELY ELT ACTIVATION, STOP THE ELT TRANSMISSION AS
DESCRIBED IN § E - RESTORING ELITE TRANSMITTER IN ARMED (STANDBY) - AND
INFORM THE CLOSEST SEARCH AND RESCUE (SAR) OR AIRPORT CONTROL TOWER
IMMEDIATELY.
A. General
ELiTe TRANSMITTER is getting its Cospas-Sarsat Identification message content from ELiTe Coding Tag
(RFID wireless connection).
ELiTe ELT states are:
– OFF, ELiTe TRANSMITTER cannot transmit any distress frequencies(operationally inactive),
– ARMED, normal position on board A/C. ELiTe TRANSMITTER waits a triggering signal (standby),
– ON (distress), ELiTe TRANSMITTER is transmitting the distress frequencies 406.040 MHz & 121.5 MHz,
– SELFTEST, ELiTe TRANSMITTER performs a self-test and transmits a single self-test message on
406.040 MHz and 121.5 MHz for 0.75 second (3 frequency sweep)
– RESET, ELiTe TRANSMITTER stops transmitting distress frequencies and is restored in ARMED (standby).
NOTE: ELiTe TRANSMITTER is automatically switched to ARMED upon its installation on
ELiTe AF-BRACKET, inside ELiTe S-BRACKET or inside ELiTe S-Bag.
NOTE: ELiTe TRANSMITTER shall be removed from ELiTe S-BRACKET or ELiTe S-Bag for correct
transmission operations.
ELiTe ELT can be activated in four (4) modes:
– Manually (valid for Automatic Fixed and Survival configurations). It includes remote control panel
activation from the cockpit(Automatic Fixed)
– automatically when the acceleration sensor (G-Switch) is triggered (Limited to Automatic Fixed),
– by the mean of a water sensor (limited to Survival)
– Inflight activation via a discrete independent input (provision for future evolution, so far this activation is
similar to remote control panel activation in term of ELT transmission behavior).
B. Typical Operational scenarios
ELiTe ELT shall be used in scenarios that are in accordance with the Cospas-Sarsat submission for Type
Approval and that have been tested in Cospas-Sarsat approved laboratory (part of the TAC#).
Documentation P/N: 15E64259 Rev A Page 45
Oct. 10/17
(1) For ELiTe ELT in the Automatic Fixed configuration ELiTe AF-BRACKET shall be connected to an external
antenna as indicated in Figure 14 with RF connection losses between 0.2 and 1.5 dB max.
Physical installation of the external antenna shall not degrade the antenna specification (VSWR and
radiation pattern).
It corresponds to the Configuration 6 “Antenna fixed to ground plane – ELT Like” as defined in Cospas-
Sarsat C/S T.007 specification.
As examples, such test configurations in Approved Cospas-Sarsat laboratory are presented here under:
External high speed antenna (blade) External low speed antenna(rigid rod).
(2) For ELiTe ELT in the Survival configuration ELiTe TRANSMITTER equipped with ELiTe Float is using its
internal dual frequency antenna for distress signals transmissions. It can be used in three different
configurations. As examples such test configurations from Approved Cospas-Sarsat laboratory are
presented here under:
(a) Configuration 5 “Water ground plane – EPIRB like” as defined in Cospas-Sarsat C/S T.007
specification, ELiTe ELT is transmitting while floating on water.
(b) Configuration 7 “Beacon on ground plane – PLB like” as defined in Cospas-Sarsat C/S T.007
specification, ELiTe ELT is transmitting while sitting on ground.
Documentation P/N: 15E64259 Rev A Page 46
Oct. 10/17
(c) Configuration 8 “Beacon above ground plane” as defined in Cospas-Sarsat C/S T.007 specification,
ELiTe ELT is transmitting while kept away from ground (insulated, no need of ground plane).
C. Automatic activation
CAUTION : IN CASE OF FALSE ACTIVATION OR TEST PURPOSE, THE OPERATOR SHALL STOP
THE ELT TRANSMISSION AS DESCRIBED IN § E -RESTORING ELITE TRANSMITTER IN ARMED
(STANDBY) WITHIN 50 S. AFTER THIS DELAY THE ELT WILL TRANSMIT ACTUAL DISTRESS
SIGNALS ON THE TWO AVAILABLE DISTRESS FREQUENCIES (406.040 & 121.5 MHZ).
The acceleration sensor has detected an impact sufficient to trigger it. The LCD display (3) indicates ELiTe
TRANSMITTER activation.
Upon automatic activation, the ELiTe TRANSMITTER performs one self-test (see §F Beacon self-test 6.F)
and displays self-test report on LCD (Figure 20 [3])
In this state, as long as the ELT is in operation, it sends the relevant distress frequencies.
D. Manual activations
Such manual activation can be achieved either by using ELiTe TRANSMITTER keypad (when accessible) or
remote control panel (when available).
There are three cases in which a distress signal may be triggered manually:
Documentation P/N: 15E64259 Rev A Page 47
Oct. 10/17
– the acceleration sensor (G-switch) has not been triggered but a distress signal must be sent (injured
passengers, aircraft out of operation ...),
– the aircraft is on the ground and must be evacuated.
– When a crash or ditching condition is imminent.
(1) First case: from the Remote Control Panel (Limited to Automatic Fixed configuration)
Raise the safety cover (guard) on the remote control panel (RCP) and place the switch in the ON position.
After two short blinks on RCP indicator, an automatic self-test sequence is performed (see § F(4) -Self-test
by mean of ON on remote control panel (RCP)).
CAUTION : IN CASE OF FALSE ACTIVATION THE OPERATOR SHALL STOP THE ELT TRANSMISSION
AS DESCRIBED IN § E -RESTORING ELITE TRANSMITTER IN ARMED (STANDBY) WITHIN 50 S.
AFTER THIS DELAY THE ELT WILL TRANSMIT ACTUAL DISTRESS SIGNALS ON THE TWO
AVAILABLE DISTRESS FREQUENCIES (406.040 & 121.5 MHZ).
This transmission state is permanently displayed on the Remote Control Panel indicator.
After about 50s delay, the ELiTe TRANSMITTER will transmit the two actual distress frequencies 121.5-
406.040 MHz.
In this state, as long as the ELT is in operation, it sends the relevant distress frequencies.
(2)Second case: from the ELiTe TRANSMITTER front panel (valid for Automatic Fixed & Survival
configurations)
– Slide the safety transparent cover SOS out of the ON button (1),
– Press and release the ON button (Figure 20[1]),
An automatic self-test sequence is performed (see § F(3) -Self-test by means of ON button on ELiTe
Keypad).
CAUTION : IN CASE OF FALSE ACTIVATION THE OPERATOR SHALL STOP THE ELT TRANSMISSION
AS DESCRIBED IN § E -RESTORING ELITE TRANSMITTER IN ARMED (STANDBY)-. WITHIN 50 S.
AFTER THIS DELAY THE ELT WILL TRANSMIT ACTUAL DISTRESS SIGNALS ON THE TWO
AVAILABLE DISTRESS FREQUENCIES (406.040 & 121.5 MHZ).
This transmission state is permanently displayed on the Remote Control Panel LED.
After about 50s delay, the ELiTe TRANSMITTER will transmit the two actual distress frequencies 121.5-
406.040 MHz.
In this state, as long as the ELT is in operation, it sends the relevant distress frequencies.
NOTE: For Survival configuration, ELiTe TRANSMITTER shall be removed from ELiTe S-BRACKET or
ELiTe S-Bag and put in service out of the A/C. It is recommended to attach it to a life raft or survivors in case
of ditching.
Documentation P/N: 15E64259 Rev A Page 48

E. Restoring ELiTe TRANSMITTER in ARMED (standby)
In the event of a false maneuver or untimely operation, stops distress transmission.
The ELiTe TRANSMITTER is restored in its ARMED (standby) mode by pressing the “TEST/RESET”
pushbutton on the remote control panel or “TEST or RESET” button on ELiTe TRANSMITTER keypad..
NOTE: This control is not active if the remote control panel ON/ARMED switch is in ON position.
NOTE: When the manual activation had been done through the RCP, it shall be reset by the mean of RCP,
ELiTe TRANSMITTER “TEST or RESET” keypad button has no action.
NOTE: When the manual activation had been done through ELiTe TRANSMITTER “ON” keypad button, it
can be reset by the RCP or ELiTe TRANSMITTER “TEST or RESET” keypad.
NOTE : Stopping distress signal transmission by means of the remote control panel does not switch the
ELiTe TRANSMITTER OFF. It is restored in ARMED (standby) mode.
When “TEST or RESET” button on the keypad is used, ELiTe TRANSMITTER request a manual
confirmation.
The following message is displayed on LCD
– Press OK to confirm.
CAUTION : WITHOUT ACTION ON KEYPAD WITHIN 5 SECONDS, ELITE TRANSMITTER REMAINS IN
TRANSMISSION (DISTRESS).
Documentation P/N: 15E64259 Rev A Page 49
Oct. 10/17
F. Beacon self-test
CAUTION : ELTA RECOMMENDS TO PERFORM THE SELF-TEST WITHIN THE FIRST 5 MINUTES OF
ANY HOUR BECAUSE THE ELT IS SENDING 121.5 MHZ SIGNAL FOR ABOUT 0.75 S
(THREE 121.5 MHZ SWEEPS) DURING THIS SELF-TEST PROCESS (LIMITATION OF
FALSE ALERT).
The ELiTe TRANSMITTER is designed to perform a self-test either, from the remote control panel or from its
keypad.
Actual self-test incorporates transmission on 121.5 MHz for about 0.75s that can be listened on any VHF
receiver.
NOTE: After each activation, either manual or automatic, ELiTe TRANSMITTER performs a self-test before
entering in the distress mode.
While installed on any type of mounting bracket or bag ELiTe TRANSMITTER is automatically set to
ARMED.and reads the content of the relevant ELiTe Coding Tag located on/in ELiTe BRACKET or Bag.
ELiTe TRANSMITTER shall be in “ARMED” position in order to allow the self-test process.
Basically, the self-test result (report) is displayed on both ELiTe TRANSMITTER LCD display and on Remote
Control Panel (RCP) indicator when RCP is present (Automatic Fixed configuration).
RCP indicator gives a “summary” of the potential failures, failure detail is displayed on ELiTe
TRANSMITTER LCD display.
The actual Cospas-Sarsat Identification message (official 15 hex) is displayed on ELiTe TRANSMITTER
LCD display upon request (status) and for each self-test.
Self-test report includes “Failure” and “Warning” information’s. Failures are displayed first, followed by the
warning.
Failure corresponds to performances being out of specification that would need some short term
maintenance tasks, but ELiTe TRANSMITTER will operate and transmits distress signals in “a degraded
mode”.
Warning corresponds to information that would require customer attention in a short/medium term, such as
battery replacement expiry date coming soon.
Actual list of failure is (not listed per importance level):
• Impossibility to read ELiTe Coding Tag information,
• External antenna connection or failure,
• Software executable code corrupted,
• Low output power on 406.040 MHz - UHF
• Low output power on 121.5 MHz – VHF,
• Frequency not being 406.040 MHz – UHF – synthesis, PLL not locked,
• No +28 Vdc (Relevant for Automatic Fixed configuration requiring Lat & Long information from A/C
data bus)
Documentation P/N: 15E64259 Rev A Page 50
Oct. 10/17
Actual list of warning is (not listed per importance level):
• Total cumulative transmission above one (1) hour,
• Remaining battery capacity (x% of typical value),
• Maximum number of self-test reached,
• Next scheduled battery servicing date (from 0 to 4.5 calendar year starting at the date of the last
battery servicing),
• Battery replacement required in x month (from 4.5 and 5 calendar years starting at the date of the
last battery servicing),
• RCP fault,
• ELiTe AF-BRACKET fault,
• Maximum number (65) of GNSS self-test reached (relevant for Survival configuration)
Basically the following sequences are proposed with the messages displayed on ELiTe TRANSMITTER
LCD:
• Backlight duration for standard message is set to 3 seconds (power saving). Content of message
remaining displayed after backlight can be seen by using external source of light (such as flasklight
for example).
• Standard messages are displayed for 3 seconds,
• Confirmation messages are displayed for 5 seconds (ELiTe TRANSMITTER returns in its current
state if confirmation (OK) is not performed within these 5 seconds,
• The three colors LED (green, red, orange) can briefly blink (start of task) or be permanently
illuminated for 3 seconds (action/state confirmation).
Example of timing diagram about message display, blinking, illumination of three colors LED are presented
in APPENDIX C – TIMING DIAGRAM EXAMPLE for better understanding.
NOTE: When the self-test is performed on ELiTe TRANSMITTER alone (removed from any bracket or bag),
the report displayed on LCD will indicate “No valid Tag” and will display the content of the C/S ID issued
from its internal memory. Do not take care of this message. It will be corrected in near future with the
indication better related to “Missing ELiTe Coding Tag”.
NOTE: Even if the self-test report is negative, it will not block the activation of ELiTe TRANSMITTER

7. MAINTENANCE OF THE ELiTe ELT
CAUTION: FOR MAINTENANCE PURPOSED, DURING SHIPPING OR TRANSPORT OF THE ELT MAKE
SURE THAT ELITE TRANSMITTER IS IN “OFF” POSITION. THIS VERIFICATION WILL
AVOID FALSE ACTIVATION DURING TRANSPORT AND MANIPULATION IF THE ELT
REMAINS IN “ARMED”.
NOTE: There is no maintenance process on ELiTe S-BRACKET, ELiTe S-Bag & ELiTe Float (pure simple
mechanical parts). They are considered as “consumable” and shall be replaced by new part in case of
damage.
A. Beacon self-test
(1) ELiTe standard self-test (applicable to Automatic fixed and Survival configurations)
CAUTION : THE SELF-TEST PROCEDURE (PARAGRAPH 5.D.) MUST BE RESPECTED TO AVOID
UNTIMELY BEACON ACTIVATION.
The manufacturer recommends that a beacon self-test should be performed regularly. The highest rate is
one per month (65 for the typical 5 years battery replacement interval). Normally this task is added to other
periodic maintenance task such a “A” check. In any event the user must comply with the applicable
regulations in the country concerned governing the self-test period. In accordance with EUROCAE ED-62A
requirement the self-test needs to be performed at least once every six months.
A higher rate of self-test is possible but will reduce the standard 5 years battery servicing interval.
When the maximum number (65) of self-test is reached a ”Warning” is displayed on the LCD display.
(2) ELiTe TRANSMITTER GNSS self-test (limited to Survival Configuration)
The purpose of this GNSS self-test is to check the correct operation of the internal complete GNSS receiver.
It is not getting the actual location nor transmits any Cospas-Sarsat 406.040 MHz self-test message.
The GNSS self-test can only be triggered from ELiTe TRANSMITTER keypad. It is limited to maintenance
personnel and it is not accessible by immediate single action on the keypad.
The highest rate is one per month (65 for the typical 5 years battery replacement interval). A higher rate of
GNSS self-test is possible but will reduce the standard 5 years battery servicing interval.
CAUTION : THE GNSS SELF-TEST PROCEDURE SHALL BE PERFORMED UNDER UNOBSTRUCTED
VIEW OF THE SKY ALLOWING CORRECT GNSS SATELLITE SIGNALS RECEIPTION.
CAUTION : IT IS NOT RECOMMENDED TO PERFORM THE GNSS SELF-TEST FOR ELITE IN
AUTOMATIC FIXED CONFIGURATION AS THE RESULT WILL ALWAYS BE NEGATIVE DUE
TO THE IMPOSSIBILITY TO GET UNOBSTRUCTED VIEW OF THE SKY ALLOWING
CORRECT GNSS SATELLITE SIGNALS RECEIPTION INSIDE A/C STRUCTURE.
GNSS self-test is positive when the acquisition of the time from GNSS satellite constellation is achieved.
GNSS self-test is negative when the above time is not achieved within 4 minutes. Duration of the GNSS
self-Test is related to the time acquisition, up to 4 minutes.

– Press at the same time on “ARROW” AND “TEST or RESET” buttons on ELiTe TRANSMITTER
keypad,
– Press one more time on “ARROW” for the selection of the GNSS self-test function,
– Press “OK” to confirm.
Orange LED is blinking and the following screen is displayed on ELiTe TRANSMITTER LCD, backlight is on
for 10 seconds, display remains for the entire duration of the GNSS self-test (can be seen using an
additional source of light).
If the acquisition of the time is possible (within 4 minutes max), the following screens are displayed in
sequence. Green LED is blinking.
Documentation P/N: 15E64259 Rev A Page 61
Oct. 10/17
If the acquisition of the time is not possible, after 4 minutes the following screen is displayed and the red
LED illuminates for 5 seconds
