Q

How do you test an old style ELT? How about the newer 406 Mhz ELT?

A

Old: Must be done only during the first 5 minutes of any UTC hour and you can only test it for up to 5 seconds.

406 Mhz: Test only as directed by the manufacturer. Testing any other way may produce a false alert. Selection of the ‘on’ position for more than 50 seconds will send an alert to the nearest Joint Rescue Coordination Center.

406 Mhz beacons have a self-test function, which also tests the power output of the 121.5 transmitter.

Q

If you carry a personal/portable ELT, what is the best practice if in an emergency?

A

Because it is a line of sight device, moving it to a clear and, if possible, elevated area even just 8 feet off the ground can increase the range by 20% - 40%

Also putting it on top of or near metal

Don’t keep it on your person, as your body will absorb most of the signal
