A.
Applicability
1)
This section only covers inspection, testing, and fault isolation procedures specific to the Dongle.
2)
Refer to the applicable ELT Description, Operation, Installation & Maintenance Manual associated with
the ELT to coordinate the requirements herein with the requirements for inspection, test, and fault
isolation of the ELT system as a whole.
B.

The Dongle is considered an integral part to the ELT system, and as such is subject to the periodic
inspection and testing required by the regulatory authorities governing the installation, operation, and
maintenance of ELT systems.
2)
Refer to the applicable ELT Description, Operation, Installation & Maintenance Manual associated with
the ELT for references to the regulatory requirements.
3)

Test Procedures
A.
General
CAUTION
:
ANY ELT RUNNING V133 SOFTWARE (SEE PRODUCT LABEL) TRANSMITS A
FIXED TEST MESSAGE AT ELT RESET, NECESSITATING A “LIVE”
BROADCAST TO READ THE ACTUAL MESSAGE. ANY ELT RUNNING V134 OR
V135 SOFTWARE TRANSMITS THE ACTUAL 406 MHZ MESSAGE AT RESET.
ALL MUST BE TESTED IN AN RF CONTAINER, SCREEN ROOM, OR
CONNECTED TO A DUMMY LOAD VIA THE ANTENNA COAX CONNECTION.
1)
This task consists of two subtask testing requirements:
a)
24-bit address programming test, which verifies ELT/Dongle 24-bit address reprogramming
functionality by initiating reprogramming and checking for the address change or an error
indication.
b)
15-digit hex ID determination, which reads the programmed hex ID, country, and country code
broadcast in the 406 MHz message and provides instructions for relabeling and re-registering the
ELT, as applicable.
B.
24-Bit Address Reprogramming Verification Test
1)
This is a recommended periodic test.
NOTE: This test procedure verifies the ELT/Dongle has updated the aircraft 24-bit address ID in the
ELT programming.
