When an ELT signal is heard, notify the ARTCC or proper facility that will coordinate with the
rescue coordination center (RCC). Try to get fixes or bearings on the aircraft. Ask for the help of other
aircraft aviators operating in the area. Send any pertinent information to the ARTCC. When the signal
strength shows it may be coming from a source on the airport, tell facilities personnel and the ARTCC.
Let the ARTCC know when the signal source is located or ended.
ATC personnel shall not leave their duty stations to locate the source of an ELT signal.
Operational testing of ELTs has been authorized during the first five minutes of each hour,
not to exceed three audio sweeps.
If two-way radio communication with an aircraft is lost, broadcast clearances through any
available communication means, including the voice feature of a NAVAID. You may also broadcast a
clearance for the aircraft to proceed to its filed alternate airport at the minimum en route altitude if the
aircraft operator agrees.
