86(5¶6+$1'%22. Page 11 Feb 15/03 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. Several other countries have shown an interest and will soon be joining 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. Following an in-depth study phase, ELTA has arrived at highly conclusive technical results, and experimental and operational use of the "ground" equipment have proven this equipment’s reliability and ease-of-use. B. System organization (Ref. Fig. 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 /ocal 8ser 7erminals (LUT). These ground stations determine the position of the emergency transmitters and then retransmit the position data to the designated 0ission &ontrol &enters (MCC). The MCCs in turn retransmit these data to the appropriate 5escue &oordination &enters (RCC) so that they can start the search and rescue operations. * COSPAS-SARSAT : COSPAS = Kosmicheskaya Sistyema Poiska Avariynych Sudov SARSAT = Search and Rescue Satellite-Aided Tracking

86(5¶6+$1'%22. Page 13 Feb 15/03 C. The distress frequencies 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 or 243 MHz frequencies. It should be noted however that the 406 MHz beacons also transmit 121.5 MHz and 243 MHz signals 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. D. 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)Satellites low earth orbiting: 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)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 zone and memorized by the satellites. Automatic processing of the 406 MHz digital messages allows the beacons to be located and the carrier mobile to be identified.
86(5¶6+$1'%22. Page 14 Apr 17/03 2. GENERAL DETAILS OF THE ELT ADT 406 AP A. Purpose of the ELT ADT 406 AP (Ref. Fig. 2) The ELT ADT 406 AP consists of a beacon that incorporates means of attachment. The ELT ADT 406 AP is designed to transmit a digital distress signal to satellites that are part of the COSPAS/SARSAT SYSTEM. These satellites transmit the captured signal to the reception stations on the ground. This signal is transmitted on the 406.028 MHz frequency and is used to precisely locate and identify the ELT ADT 406 AP. It also transmits a 121.5 MHz and 243 MHz signal to facilitate the final approach of the distress scene (homing). It can be triggered manually or automatically by means of an acceleration sensor (G.switch in accordance to EUROCAE ED-62 standard). This ELT meets the latest JAR OPS and ICAO recommendations. Any encoding protocol defined by COSPAS/SARSAT can be used with ELT ADT 406 AP including country code assignation. ELT ADT 406 AP- Presentation Figure 2 Metalic stap

86(5¶6+$1'%22. Page 18 Apr 17/03 3. DESCRIPTION OF THE ELT ADT 406 AP AND OF THE AIRCRAFT COMPONENTS A. General description (1)Introduction This beacon from the ADT406 family derives from the ADT 406 AF/AP model. Consequently, this beacon features the functional capabilities of the AF/AP besides its flotation gear, the attachment interface and its flexible antenna entirely compatible with Cospat/Sarsat. (2)The ELT ADT 406 essentially consists of : – an ADT 406 AP beacon transmitter – a whip antenna, – labels, – an activation / identification module, – a support. (3)The ELT ADT 406 AP basic aircraft components consists of : – a remote control unit, – an external antenna. Note : this beacon can be used in survival mode without these elements. B. Detailed description (Ref. Fig. 7) (1)The ADT 406 AP beacon The ADT 406 AP beacon mainly consists of : – a whip antenna, – a power supply module, – an electronic assembly, – a mechanical assembly, – a float. The front face of the electronic assy is equipped with the following components : – a REMOTE CONTROL electrical high density 15 pins female connector (10) for connecting up to the aircraft remote control panel or programming tools, – a BACK UP WHIP ANT. TNC female connector (13) for connecting up the antenna, – an EXT. ANT. BNC female connector (9) for connecting up the external antenna, – an ARMED/OFF/ON lockable toggle switch (12) for activating the beacon, – a TX indicator light (11) indicating beacon activation (real distress and self-test).

86(5¶6+$1'%22. Page 21 Feb 15/03 ELT ADT 406 AP aircraft components (f)Remote control unit The remote control unit integrated in the aircraft cockpit consists of : – a RESET/TEST 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 this position, except in the case of manual distress triggering. The beacon is integrated in the aircraft as far aft as possible and so it must be connected to the remote control unit. This remote control unit enables beacon operation to be forced to ON, to be tested (TEST) or shutdown and restore in standby or ARMED mode (RESET) in the event of an untimely triggering of the ELT, from the aircraft cockpit. (g)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. The cable lenght should remain as short as possible in order to RF keep losses as close as possible to 0.5 to 1 dB at each frequencies (121.5/243/406.028 MHz).
86(5¶6+$1'%22. Page 22 Feb 15/03 4. INSTALLATION OF THE ELT ADT 406 AP A. General 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 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, – inspected by representative authority. B. Installation of the beacon on the aircraft (Ref. Fig. 4) In the case of use in automatic mode, the beacon shall be installed in the rear of the aircraft in order to maximize the probability of ELT survival in case of crash. However, it can be installed in another position in survival mode. The activation / identification module DIRECTION OF FLIGHT must be parallel with the aircraft flight axis as indicated by the beacon's label. The activation / identification module direction and the A/C forward/aft directions must be respected to ensure correct acceleration sensor (G.switch) operation (See Fig. 4). 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. Tolerances on the Axis for Installation of the ELT ADT 406 AP Figure 4
86(5¶6+$1'%22. Page 23 Feb 15/03 The beacon can be installed in any position (normal, upside down, right side, left side) with respect with the G-Switch activation direction stated on figure 4. The activation / identification assy of the beacon can be installed in four positions. Three alignment pins on the beacon board allow to set it in the required position. A cap is installed in one of the four holes of the activation / identification assy who is unused. 7KLVFDSVKDOOEHDVVLJQHGXSRQWKHLQLWLDOLQVWDOODWLRQDQGZLOONHHSWKLVSRVLWLRQLQPHPRU\IRUIXUWKHUEHDFRQUHSODFHPHQWUnstowed objects must be not able to impact the beacon. Attach the beacon to the fuselage of the aircraft by means of four M4 bolts. Four 5 mm diameter holes at the corners of a 210 mm x 45 mm rectangle are drilled in the beacon. 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 attachment points are similar to those of the ADT 406 AF/AP beacon.

86(5¶6+$1'%22. Page 25 Feb 15/03 C. External antenna installation This antenna should be approved by ELTA. ELTA recommend to use P/N 25988 (antenna model 2624-82 manufactured by CHELTON) 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. Standart 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 is recommended with a length lower than 2 meters to keep losses close to 0.5 dB. Connect the connector to the antenna and to the EXT. ANT. access on ELT, and install the coaxial cable. This cable must be fixed to rigid aircraft structure all along its routing, and it should be as short as possible to avoid Radio Frequency losses and/or cable destruction in case of crash. D. Remote control unit installation The ELT ADT 406 AP can be remotely controlled by using a remote control panel installed in the cockpit of the aircraft. The maximum length of this link is 200 meters and requires no grounded cable. The link requires 4 wires.
86(5¶6+$1'%22. Page 26 Apr 17/03 The following simplified diagram shows the wiring between the ELT ADT 406 AP and its peripherals : – The Remote Control Panel (in cockpit) identified as "RCP", – the external antenna noted as "EA", – the whip antenna noted as "BA". The EA is connected to the ELT ADT 406 AP BNC female connector (5). The BA is connected to the ELT ADT 406 AP TNC female connector (1). The RCP is connected to the ELT ADT 406 AP high density 15 pins female connector (3). ELTA recommend to use P/N 16243 for RCP connector and P/N 231 plus 232 for ELT. A three position guarded switch (2) controls the ELT ADT 406 AP. A red indicator (4) displays the ELT ADT 406 AP state. ADT 406 AP Beacon Installation Figure 6

A. Automatic activation The acceleration sensor has detected an impact sufficient to trigger it. The indicator light (11) and the aural indicator indicate beacon activation. If the aircraft has to be evacuated, refer paragraph B.(2) second case. Otherwise do not do anything and leave the beacon in operation until the rescue team arrives. B. Manual activation There are two cases in which a distress signal may be triggered manually : – 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. (1)First case, from the Remote Control Raise the safety cover (guard) on the remote control unit and place the switch in the ON position (lever upwards). An automatic self-test sequence is performed. Then the indicator light (11) and the aural indicator indicate beacon activation. This signal is permanently displayed on the Remote Control LED. Do not do anything and leave the beacon in operation until the rescue team arrives. (2)Second case, from the beacon Place the beacon switch (12) in the ON position (pull and slide). An automatic self-test sequence is performed. Then the beacon enter in a waiting condition for about 30s. This state is displayed by flashing on indicator light (10) 1.75 s ON, 0.25 s OFF. This delay will avoid unwanted activation (false manoeuvre). Then the indicator light (11) and the aural indicator indicate beacon activation. The actual distress signal is transmitted. This state is displayed by flashing on indicator light : 0.5 s ON, 0.5 s OFF.
86(5¶6+$1'%22. Page 29 Apr 30/03 If the aircraft has to be evacuated, Follow the instructions : - unfasten the strap (and the cable if relevant), - remove the beacon from its bracket, pull firmly to brake the retaining metallic strap (14, Ref. Fig. 7). - extend the antenna and take the beacon with you.
86(5¶6+$1'%22. Page 30 Apr 17/03 C. Beacon shutdown In the event of a false manoeuvre or untimely operation, shutdown the beacon. The beacon is shutdown by pressing the RESET/TEST pushbutton on the remote control unit. This control is not active during the self test sequence or if the ON/ARMED switch is in ON position. NOTE : Stopping distress signal transmission by means of the remote control unit does not switch the beacon OFF. It is restored in ARMED mode.

The highest rate is one per day. Normally this task is added to other periodic maintenance task such a “A” check. In all events the user must comply with the applicable regulations in the country concerned governing the self-test period. The self-test must only be performed when the order to do so is given or by the competent authorities. A higher rate of self-test will reduce the 5 years battery servicing. &$87,217+(6(/)7(67352&('85(3$5$*5$3+'0867%(5(63(&7('72$92,'817,0(/<%($&21$&7,9$7,21 B.
