APPENDIX A – ELT REGISTRATION
TASK 25-62-30-990-801
1. Background Information
SUBTASK 25-62-30-990-001
A. Hex ID Code
(1) 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, and
(c) Latitude and longitude position data, if equipped with a navigation interface device.
SUBTASK 25-62-30-990-002
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.
(a) Owner’s name,
(b) Address,
(c) Telephone number,
(d) Aircraft type, and registration number.
SUBTASK 25-62-30-990-003
C. Registration Information Resources
(1) Refer to COSPAS-SARSAT documents G.005 and S.007 for information regarding ELT
programming and registration. These documents are available at www.cospas-sarsat.org
