Sierra Industries received an STC for an Artex C406 (406 MHz) emergency locator transmitter (ELT) for installation on the Cessna Citation 500, 501, 550, 551, S550 and 560. According to a company spokesman, it provides a “cost-effective solution” for operators to update to current standards. In early 2009 U.S. emergency distress satellites ceased monitoring the older 121.5 MHz emergency frequency band in favor of the more accurate 406-MHz standard. Although a 406-MHz ELT is not yet required in the U.S., numerous countries, including Canada, Mexico and the European Union, have established, or are in the process of implementing, the standard. The Artex C406 provides an integrated ELT-to-navigation interface and transmits latitude and longitude position information with an accuracy of 100 meters. The unit operates on 121.5-, 243- and 406-MHz frequencies and features a five-year battery life. Sierra’s installation includes the ELT unit, high-speed blade antenna, wiring and removal and reinstallation of cabin interior components as necessary. The Artex C406 unit is priced at $8,500 for basic installation or $12,000 installed with GPS position broadcast capability.
