Emergency locator transmitters

Air Precision manufactures airborne emergency locator transmitters (ELT) compatible with the COSPAS-SARSAT system. This system consists of a series of satellites which detect distress beacons and relay the radio signals to ground based control centers (CCM) world-wide. These centers are responsible for locating the beacon and initiating search operations when a beacon transmits. Using 406Mhz beacons permits a faster and more precise location than bi-frequency 121.5 and 243Mhz beacons.

Our beacons emit the registration of the aircraft in which they are installed, for 48 hours (at -20°C, and longer at ambiant temperatures). They can be set manually, or from the cockpit, or automatically, by the crash sensor included in the beacons (g-switch). The 406Mhz beacons have an autotest function. The beacons are usually installed in the upper rear fuselage. They are also portable.

You can visit the COSPAS-SARSAT website if you are interested by this system of search and rescue.

Air Precision is developing a new model of tri-frequency ELT (ELT96-1). Please feel free to contact us if you want more information.
