USER'S HANDBOOK
Any encoding protocol defined by COSPAS/SARSAT can be used with ELT ADT 406² AF / AP including
country code assignation.
The purpose of the Activation/Identification module on the top of the ELT transmitter is to store on board the
A/C the Cospas-Sarsat identification. This module is attached to the A/C structure by the metallic strap. It will
keep, on board the A/C, the Cospas-Sarsat Identification code. This module is transferable i.e. can be
installed after removal on a new ELT transmitter (from the shop for maintenance as example). The operator
is sure that the new ELT transmitter will transmit the correct Cospas-Sarsat message upon activation.
The identification code is stored in the non volatile memory and will not be lost upon, module or battery
removal.
The ADT 406 AF/AP ELT can be operated in a non-location protocol ELT when the transmitter is installed
alone on board the A/C (Cospas-Sarsat Identification message encoded as "Short"), or in user location
protocol ELT when the transmitter is installed with its optional dedicated "Navigation Interface" equipment
that receive the A/C location (Latitude & Longitude) from the A/C data Bus (Cospas-Sarsat Identification
message encoded as "Long" and GPS accuracy transmitted is 4' of angle as specified by Cospas-Sarsat).
In CANADA the selected Cospas-Sarsat protocol must be the "Aircraft 24 bit address" either for short or long
Cospas-sarsat message.
If the ownership change, the ELT shall be re-coded, new 15 digit Hex Code, with the appropriate country
code and coding protocol as selected or required by the country of the new final operator. Contact ELTA for
additional details (www.elta.fr ).
