FCC bans 121.5 mHz ELT's

Hmmm... I suppose all this means is that 121.5 mHz ELT's are no longer allowed to be manufactured/sold/installed. It does not prohibit existing installations (such and myself and thousands of other FAA-registered aircraft have.)

It makes sense...I mean, who would actually buy a 121.5 mHz ELT knowing the current state of the regs? But the wording can be alarming.

AvWeb.com wrote:he Federal Communications Commission took the general aviation world by surprise when it said in a recent report it will prohibit the sale or use of 121.5 MHz emergency locator transmitters, effective in August. The Aircraft Electronics Association said it just learned of the new rule today, and has begun working with the FAA, FCC and others to allow for timely compliance without grounding thousands of general aviation aircraft. The 121.5 ELTs are allowed under FAA rules. The FCC said its rules have been amended to "prohibit further certification, manufacture, importation, sale or use of 121.5 MHz ELTs." The FCC says that if the 121.5 units are no longer available, aircraft owners and operators will "migrate" to the newer 406.0-406.1 MHz ELTs, which are monitored by satellite, while the 121.5 frequency is not. "Were we to permit continued marketing and use of 121.5 MHz ELTs ... it would engender the risk that aircraft owners and operators would mistakenly rely on those ELTs for the relay of distress alerts," the FCC says. AOPA said today it is opposed to the rule change.

"The FCC is making a regulatory change that would impose an extra cost on GA operators, without properly communicating with the industry or understanding the implications of its action," said AOPA Vice President of Regulatory Affairs Rob Hackman. "There is no FAA requirement to replace 121.5 MHz units with 406 MHz technology. When two government agencies don't coordinate, GA can suffer." The AEA said dealers should refrain from selling any new 121.5 MHz ELTs "until further understanding of this new prohibition can be understood and a realistic timeline for transition can be established."

Re: FCC bans 121.5 mHz ELT's

This says they are banning the use of 121.5 Mhz ELT's, did they forget that 406 MHZ. ELT's also trasmitt on 121.5, and so do all the portable PLB's carried by backpackers, boats, snowmobiles, etc.

Re: FCC bans 121.5 mHz ELT's

Go to: http://hraunfoss.fcc.gov/edocs_public/a ... -103A1.pdf and read section "H" for the details

This: "18. We therefore amend the Commission’s rules to prohibit further certification,
manufacture, importation, sale or use of 121.5 MHz ELTs."

It appears the FCC is also banning the USE of 121.5 ELT's not just the certification and/or importation.

I read that as we can't use them at all..even existing installations....

Re: FCC bans 121.5 mHz ELT's

Also from the NOTAM issued by the Idaho Pilots Assn. the start date on this is August.

From what I read in the FCC document it will be sixty days after the ruling is published in the Federal Register, which would jive w/ an August deadline.

Now does that mean the FAA will declare you aircraft non-airworthy on that date or just choose to ignore the FCC?

Just because the FCC issues the reg does not mean the FAA concurs.

Re: FCC bans 121.5 mHz ELT's

Re banned use- Perhaps because the freq is going to be reassigned, and they don't need downed or distressed pilots interfering with someone's ability to raise and lower their garage door, or text their friends over a cell network??

I read it the same way Tadpole. Doesn't this FCC outfit realize they are a government agency and as such are mandated to waffle on significant unpopular regulatory changes until after the November general election?

I was getting ready to order a new 406 slash 121.5. Does this mean that they will be illegal. In a short time it will be required have a 406 slash 121.5 in Canada. WTF are we supposed to do here?

Re: FCC bans 121.5 mHz ELT's

I thought I read something about the use being exempted for FAA, but apparently that's just wishful thinking by AOPA.

Wait until all the alphabets fight each other and see what really happens. I don't see the FARs changing that rapidly.

Re: FCC bans 121.5 mHz ELT's

Was thinking of a trip to Mexico and I thought that I read that the new ELT is required. If so I need to upgrade now and would like the unit to be legal in Mexico and Canada. Maybe even USA.

Re: FCC bans 121.5 mHz ELT's

What about my 121.5/406 ELT that I installed last year..is it banned because it still has 121.5? :(

Re: FCC bans 121.5 mHz ELT's

I just had a thought....

You're not "using" that 121.5 mHz ELT until it starts transmitting. Do the new combo 406/121.5 ELT's that you guys have installed let you set a preference for which frequency is using during activation? Like a DIP switch or something inside?

I predict an exemption, or new extension or something within the next few days, but yeah...don't transmit your ELT on 121.5 and I don't see how just having it installed is a violation. If 121.5 is supposedly so difficult to track down, and sat coverage has been suspended on that freq, I don't see how the FCC is going to violate anyone anyway.

Next....

Re: FCC Bans 121.5 ELTs

I understand banning the sale of future 121.5 units to get people to buy the 406s.
However how high was the person that said it would make the aviation world safer by banning the USE of ANY emergency locator!

Also grounding aircraft that spend bucks to keep in the air, that burn really expensive fuel, pay hangar fees, etc doesn't seem like a good idea in this economy, a smart person might think that now would be a good time to ENCOURAGE people to go fly their airplanes!!

I have a friend that has 121.5 on his plane as well as a portable 406 w/ GPS I think my friend would probably extend a big F' you to the fine aviation experts at the FCC.

Re: FCC bans 121.5 mHz ELT's

Ok lets get this straight all 406 ELTs transmit on 121.5 they have to, that is how SAR hones in on your exact location.

The way a 406 ELTs works is every 50 seconds it sends out a 1/2 sec data burst on one of the 19 allowed 406 freqs at 5W trying to reach (ether or both) one of many low earth orbiting satellites that pass every 90 min and it if it has GPS it can hit one of the geo satellites. The rest of the 50 seconds in between the data bursts it re-tunes to 121.5 and transmits on 0.5W as a honing beacon.

So just because your 406 transmits on 121.5 does NOT make it a 121.5 ELT. 121.5 ELT are ones that solely transmit on that freq.

Last numbers I saw was that only 15% of GA aircraft have a 406 ELTs. Since satellites don't pick up or read the 121.5 freq (turned off in 2009) only 15% are being aided by satellite. The other 85% of GA relay solely on over flying aircraft monitoring 121.5 to hear there emergency.

The other number I hear all the time in CAP is that 95% of 121.5 ELTs going off are false alarms. but since they can't be easily honed in (like if a satellite could hear it) the Air Force (or Coast Guard) [namely CAP or Coast Guard Aux] has to lunch a much larger search then would be needed if 406 even w/o GPS gave a location with in 5 mile radius.

So the way I see it, the gov see's that allowing 121.5 ELTs is not only a complete waste of SAR resources chasing after false alarms but also since the satellites don't pick up the freq it offers almost no protection to the pilot. So why mandate a system and wastes resources and doesn't provide safety?

Re: FCC bans 121.5 mHz ELT's

The actual SAR rescue team that actually gets off their ass and actually hikes up the mountain and actually pulls your ragged ass out of the airplane to actually save your life... is equipped only with 121.5. This was told to our EAA chapter by a member of one of the LA County Sheriff SAR teams. The satellite is not what comes to pry the door open and get you out of the airplane.

So here's how to resolve this problem:

Have an attorney from AOPA, EAA or any pilot group demand that the FCC address the point above. Then publicly ask the FCC if they care about the preventable loss of life if someone dies because they gave up their 121.5 unit, bought a 406 unit, but the 121.5 equipped rescuers did not have the ability to find the wreck.

Then have this lawyer remind the FCC that they will be the guest of honor at the world's largest lawsuit one day soon, because (Over the pleas and objections of thousands of pilots) they outlawed the device which would have gotten the rescue team to the crash site in time.

I suspect that the congress or supreme court would back the FAA over the FAA in matters of air safety if push came to shove. I don't see this being enforceable regardless.
