Thread: ELT 406 MHz

The factory installed ELT in my 2007 CTsw is an AMERI-KING Model AK-405. It monitors freqs 121.5 and 243.0MHz. It sells on AIRCRAFT SPRUCE @ $190. The FAA has recently notified all USA GA aircraft that a new , three frequency, satellite capable 406 MKz unit, e.g., AMERI-KING AK-451 PLB "must be" installed prior to 1 Feb., 2009. This unit sells at AIRCRAFT SPRUCE @ $527. I would like to know to know if this is a "recommendation" or a "must have" directive from our FAA? Are LSA aircraft involved? Do we anticipate FD issuing such a requirement? DonBo

It's funny you should bring this up since the AOPA just had an article on it yesterday. The 121.5 frequency will not be monitored by satellites after Feb 1, 2009 making it hard to find you if you should go down. However, the 121.5 frequency can be monitored from ground and airbased rescue vehicles even after that date. It may take a little longer for you to be found.

Canada requires that you switch to the 406 frequency and Mexico does also, but will allow US registered planes to continue with 121.5. AOPA is jumping into this so there can be some sort of standard clarification. They don't want a "mandated" requiredment for 406 ELT's, but it looks inevitable down the road.

Here's a link to that article:

Hi Donbo,

I thought the conversion was optional at this time? Like Patrnflyr stated it will take a little longer to find you so pack a lunch.
