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
