Section 1 - General
The 406 MHz emergency locator transmitter (ELT) is a radio-frequency
transmitter that generates a signal to assist in search and rescue for
missing aircraft. The ELT automatically transmits the standard sweep
tone on 121.5 MHz if rapid deceleration is detected. In addition, for the
first 24 hours of operation, a 406 MHz signal containing aircraft
specific information is transmitted at 50 seconds for 440 milliseconds.
