Satellite monitoring of 121.5-MHz emergency locator transmitters (ELTs) will end as of February 1. On that date, the International Cospas-Sarsat Organization will monitor only 406-MHz ELTs, which “transmit a much stronger signal, are more accurate, verifiable and traceable to the registered beacon owner,” the FAA said. According to the agency, only about 15 percent of the registered aircraft in the U.S. are currently flying with 406-MHz ELTs.

As of February 1, search-and-rescue satellites will stop monitoring 121.5 MHz, one of the frequencies used by emergency locator transmitters. Although there is no FAA mandate requiring a switch to 406-MHz ELTs, operators should be aware that the international Cospas-Sarsat satellite system will cease to process 121.5-MHz signals on that date.

New 406-MHz emergency locator transmitters (ELT) from Emergency Beacon Corp. are at the New Rochelle, N.Y. company’s booth (No. 4074). Anticipating the February 2009 switch of search-and-rescue signal processing from 121.5 MHz to 406 MHz, Emergency Beacon is offering ELTs for both cabin/cockpit and aircraft tail installation.

The royal air force of Oman has signed a $1.5 million contract with SARBE for new generation beacons to replace SARBE 6 beacons by the end of this year. The previous generation beacons will become obsolete on February 1, 2009, as analog transmissions will no longer be monitored by the COSPAS-SARSAT network. Beyond that date only 406MHz signals will be detected.
