ELT Registration
Background Information
A.
Hex ID Code (15-Hex ID)
1)
A Hexadecimal Identification (Hex ID) is a series of digits consisting of letters A-F and
numbers 0-9 that identifies an individual beacon.
2)
The Hex ID is a message that is programmed into the beacon and is transmitted when
the beacon is activated and allowed to operate for about 50 seconds, or longer.
3)
The 15 digit version of the Hex ID (15-Hex-ID) is labeled on the outside of each
beacon.
4)
Each 406 MHz ELT is programmed with a unique hex ID code (i.e. registration code)
that is transmitted to the SAR satellite system. At a minimum, this code provides
information regarding:
a)
Unique aircraft or ELT identification
b)
Country of origin
c)
Latitude and longitude position data, when connected to aircraft navigation
system.
5)
If the beacon is reprogrammed to a new protocol, aircraft tail number, different
country, etc., the 15 Hex ID changes and the beacon requires relabeling.
B.
Reason for Registration
1)
ELT registration aids the Rescue Coordination Center (RCC) in determining if an actual
emergency exists by accessing a database containing the registration information,
which facilitates inquiries as to the whereabouts of the aircraft, existence of a flight
plan, etc. Registration information includes, but is not limited to, the following:
a)
Owner’s name
b)
Address
c)
Telephone number
d)
Aircraft type, and registration number
