ew 406-MHz personal locator beacon (PLB) aimed at military and public-service users. It is to be available in the second half of this year. Designed for the professional market, the MR 510 is housed in a rugged metal casing. It features manual or automatic actuation via water immersion or lanyard connected to the ejection seat.
The FAA Safety Team yesterday issued a notice to remind aircraft operators that satellite monitoring of 121.5-MHz emergency locator transmitters (ELTs) will end as of February 1.
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.
For the second time in three years the international requirements for ELT equipage are changing, but this time the International Civil Aviation Organization (ICAO) promises that while the new rules will ensnare more airplanes than previous requirements, implementing them will be easier than before.
Weather satellites equipped to detect emergency locator transmitters helped rescue an estimated 1,500 sailors, hikers, downed pilots and others around the world last year, according to the National Oceanic and Atmospheric Administration. Its satellites, along with Russia’s Cospas satellites, form an international search-and-rescue system. NOAA said the 171 U.S.
Old timers may remember ATC requests to report the “middle marker inbound.” But it’s been such a long time since they have been an integral part of an ILS (in 1992 landing penalties were removed for inoperative middle markers) that the FAA has proposed to officially drop the middle marker as a required component of the approach.
Most pilots by now have heard about the plan to end satellite monitoring of emergency locator transmitter (ELT) distress signals broadcast over 121.5- and 243-MHz frequencies after Feb. 1, 2009. But many might not realize there is no specific regulation in the U.S. requiring ELT upgrades to the new 406-MHz standard being adopted in much of the rest of the world.
Many operators are installing 406-MHz emergency locator transmitters in place of the 121.5-MHz units as the January 1 deadline approaches on a new regulation (FAR 91.207) that requires all U.S.-registered jets with maximum payloads of less than 18,000 pounds–virtually all business jets except business jetliners–to be equipped with an ELT.
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.
With the Feb. 1, 2009 deadline approaching to replace 121.5-MHz emergency locator transmitters (ELT) with 409- MHz units, French firm ELTA is preparing to market a personal ELT that will meet the new mandate at about one fourth the cost of a unit installed in the aircraft.
