Man this was more stressful than many mechanical/other emergencies lol. Inability to communicate across an entire area and with an emergency return to a busy airport, feels way more dangerous than someone with engine failure or whatever clearly communicating intentions and getting in safely.

[@armastat]

It would have been Much more harrowing and dangerous if it wasn't a stuck mic, but just dead silence, with all radios out including the Ident radio. there would be no way for tower to know what was going on. The pilot would have to navigate himself to a safe area and do left turns to indicate the problem and wait for the airport to visual signal him that it is okay to come back and land. You can imagine the possible errors. mistakes and bad timings that could lead to. Tho to be honest I expect the pilot to use a cell phone to call the tower, lol.

[@RealCadde]

@Taran Ainsley Which is why you always read back what ATC tells you. This way ATC knows you got the message. Thus this needn't be a big problem for anyone but the stricken aircraft. As long as ATC can get the message out that there is an aircraft on frequency with a broken radio/stuck mic. Good thing is the stricken aircraft squawked 7600 letting ATC know they had radio problems. ATC at that point closed all operations and handled it as an emergency. As a pilot, they really have to trust that ATC/tower/ground got things under control for them at that point so they can land "deaf".

[@glenmcgillivray4707]

I imagine. If you parked in a stable turn pattern to stay out of trouble. A fighter would show up and waggle it's wings at you to literally guide you to the flight-slope after an hour or so. Total loss of radio isn't crippling, just really inconvenient.

[@darkwater72]

@@glenmcgillivray4707 You are sort of correct, kind of. Sort of. But, without a radio, how would you even know which part of the sky would be safe to circle around in? From a "will the plane fall out of the sky on its own" perspective, yes, radio failure is largely a non-issue. HOWEVER, from a "I hope nothing bad happens before we unload the passengers" perspective, total radio failure is probably the single most dangerous scenario outside of a hijacking. At the speeds these things travel, you have seconds to spot another plane, figure out if your paths will intersect or not, decide what to do, and then convince a multi-ton aircraft to do it. Imagine this: You are driving a motorcycle, so you must maintain at least a minimum speed. For "reasons" normal driving conditions mean you can only see about 4 seconds in front of your vehicle, 2 or 3 seconds to the side, and are almost completely blind to the rear. Really, if you can't make contact with ANYONE, your best shot is to squawk "No Radio", circle for a while to give ATC time to notice and start clearing the area, and then line up for the longest, straightest approach path you can find and trust ATC to clear your path down. Not to disrespect your "wait for a jet escort" idea. It's a reasonable one. I just don't know where the trade off between "waiting for directions" and "land before I run into anything or cause someone else to run into something" lies.

I'm still a student pilot, so I haven't invested too much into equipment at this point, but I do plan on keeping a handheld radio with me for exactly these cases. Technically, that wouldn't actually be legal, though. Germany has some weird laws and handheld radios may only be used by ground stations. You can't even have it as emergency backup - it's the presence of the radio itself that is illegal, not its use. I'll probably keep one anyway. If I don't need it, nobody will know.

6:43 in the video the controller say "This is NY Center on GUARD" not "continue on GUARD". I only mention this as I thought it was interesting that it seemed that NY Center were the only one that could talk to them. The TRACON also tried GUARD but with no respons. I also thought it was interesting that AA2234 were still able to hear the controller even after they got a stuck mic on GUARD. How does that work? 1:22 in the video you can hear one of the pilot say "It's stuck. We have a hot mic. How does that happen?" so they knew almost straight away after they got it the second time. Great job by all and great video as always.

[@VASAviation]

I guess their stuck mic was on and off so they happened to hear NY on 21.5 then mic got stuck for a few seconds again. Happily they were able to communicate at least for a couple vectors back to the airport.

[@rivalarrival]

They had multiple radios. Any radio they set to transmit was stuck in transmit. So they set one to receive only, on guard. That let them hear transmissions from controllers. They then tuned another radio to guard, set it to transmit, and shut it off. To talk, they turned it back on and off. They got the stuck mic reports after that because it's a little clumsy to turn the transmitting radio on and off quickly. Once they had a working system, they stuck with it, demanding the controllers keep them on guard rather than trying to coordinate frequency changes.

[@mattscarf]

*BLOCKED*

[@jcota2003]

After reading a bunch of the comments complaining about how antiquated the radios are in aviation I remembered something I was told in the past. Now, this was for public service channels rather than aviation but the reason for using analog over digital was because of range capabilities and even when the channel was blocked there was a chance that a blocked communication would be heard appropriately anyway. Because digital signals require higher bandwidth and strength to be readable it reduces both the distance and the ability to overcome someone blocking the channel with a hot mic, or radio failure like this. Feel free to correct me if I am wrong but I think I am remembering correctly.

[@gastonpossel]

No expert in aviation, but with some background in electronics, signals and waves, I can affirm that, on the contrary, digital frequency-modulated signals should use less bandwidth that analog FM or AM. A digital signal gains a lot of signal-to-noise ratio, so it can be decoded pretty good in noisy environments where an analog transmission would not be readable. In terms of 'strength', that would depend on the power output of the transmitter and frequency. Higher frequencies can be blocked more easily by obstacles while lower frequencies are less sensitive (thus, more far-reaching). Normally, lower frequencies are reserved for AM comms and analog-FM comms, that's why they are usually more far-reaching (but noisier). While a digital signal uses a very narrow frequency-band, in order to represent a broader audio bandwidth, it has to increase its bitrate, which means it must use a higher frequency. I believe the problem with aviation comms is standardization: common frequencies and equipment must work seamlessly for all aircraft GLOBALLY, including models from the 60's that still fly.

[@vikkimcdonough6153]

@@gastonpossel IIRC the reason aviation radio uses AM is that if two people are transmitting on the same frequency simultaneously, with AM you hear both superimposed, making it obvious that someone's being stepped on, whereas with FM the person getting stepped on is completely blocked out with no indication that anyone else was trying to transmit.

Because air traffic still uses the outdated simplex AM transmission system that should have been replaced by a modern system similar to what everyone else uses now... With simplex AM the receiver is off when the transmitter is on. You need to press a button when you want to talk and when that button gets stuck you can only talk, not listen. Compare that to your phone where you can talk and listen at the same time, due to much more modern techniques. But in air traffic, everything is 25 years behind the times!

Seems really strange they did not yet change that very old radio system. If an aircraft can block everyone because of an open mic that really is an issue. At least I would think there should be a "distinct" frequency for both sides so that at least ground can still talk even if others can not talk because of such a mic stuck issue.

[@VASAviation]

Unfortunately that's how VHF and air band works. I think radios should be improved too (apart from ACARS or Selcal systems)

[@alfreddino2071]

True.. It should not be in this way. But there are so many factors, I can think of some: 1. Investing new system is costly. If the aviation industry has no major reason to force the manufacturer to make a new one, they will just use the existing radio system. 2. Training pilots to use the old system has lower cost than training pilots to use the new system. 3. Existing pilots need to be re-trained. 4. New radio system can't help company make money directly. Therefore, no need to be most advanced, acceptable would be fine. As long as no safety issue is compromised, company prefer not to change it.

[@AeroMad91]

It would be very difficult to replace AM VHF as the changeover would need to be coordinated world wide. Part of the problem here was the pilots not knowing their mic was stuck. Simple monitoring of this and an EICAS message notifying them might’ve helped them understand the cause of the RF failure. Disabling the affected ACP would resolve this.

[@radon360]

The likely solution is make a brief broadcast on the jammed channel informing aircraft assigned to that channel to switch to alternate frequency nnn.n, then make the same announcement on guard so that the aircraft who couldn't hear on the jammed frequency get the message as well. Now communication can resume somewhat normally on the alternate, and the offending aircraft remains on the primary. The final challenge that remains is communicating with the aircraft with the stuck mic, as their alternate receivers are likely desensed by the active transmitter. The likely reason that AAL2234 could still establish coms on guard is that 121.5 is nearly 15 megahertz off from the radio transmitting on 125.7, and the effects of receiver desense decrease the further away you get from the transmitter frequency.

It always astounds me that people try to call the aircraft with a stuck mic to tell them it’s stuck. When you are transmitting on a VHF radio, the act of transmission cuts off reception. So the ONLY ones who can’t hear you telling them that they have a stuck mic are the ones with the stuck mic. Also the American crew realized it was a hot mic but did nothing about it. They could have switched the radio to an unused frequency so as not to have disrupted the one that they were on.

improvised communications is a way to miscommunicate. There are allowances in the reg and in procedure to handle this.

[@adam-rickman]

I’m not a pilot, but got to sit up front in a citation a few times for work trip. We would hear an instruction, pilot would repeat it, then eventually ATC would repeat the same instructions. So we figured out pretty quickly they weren’t hearing us. He let me know that we had a handheld if we could figure it out soon. Eventually after unplugging and plugging things back in, it started working again. Good to know there was a backup, but pretty nervous for a little bit. I can’t imagine this type of problem in such an important area. Glad they got it taken care of without incident.

Cellphone masts aren't designed to direct signals upwards; since the vast majority of customers are on the ground. Although some commercial aeroplanes do have sat-phones.

[@Towert7]

[@BillAndersonNS]

@9:06 I don't understand with an emergency in progress because a plane with a radio failure is landing (maybe on 4R), WHY would ATC tell AA276 that they are CLEARED TO LAND on 4R. That just seems silly to clear a plane to land when clearly they should NOT be CLEARED TO LAND. Is it only the USA that clears planes to land before they are truly clear to land? It's like clearing a plane to land on speculation.

[@CAPFlyer]

Because in the US ATC is allowed to issue a CONDITIONAL landing clearance. ATC told AAL276 the conditions for his landing clearance as part of the transmission. If the crew confirms that clearance, they acknowledge the condition and be ready for the clearance to be cancelled if the conditions aren't met. As with everything - the PIC has the right to say "no" to anything they are uncomfortable with.

[@feuervogel5160]

There is a video on this topic on the channel: kzbin.info/www/bejne/kHOuqZqdqLtgbpo Outside the US, ATC usually says "continue approach, expect late landing clearance" in these situations.

[@VMCAviationVideos]

Only in the US. There was an Air Canada flight cleared for landing at SFO, then tower tried to cancel the landing clearance but Air Canada didn't her them, so they landed. If they would stop giving landing clearances 100 miles out this wouldn't have happened.

[@CAPFlyer]

[@danielrose1392]

9:00 a plane with a radio failure around and still clearing planes to land before the runway is clear. Seems a bit risky to me.

[@paulchambers6657]

Should be able to put TCAS into emergency land mode at a certain airport and it automatically lets ATC and other planes around it know what is happening.

[@VASAviation]

That's why we have squawk codes

[@stephenf3433]

TCAS (Traffic Collision Avoidance System) isn't connected to the transponder (in a basic way) and can only scan the area for returns of other planes. Now GPS systems could allow for such an idea however I think a better solution would be to send an ACARs message to ATC and all surrounding aircraft

[@StephenMiller2001]

Maybe ACARS but TCAS wouldnt really help

[@beerbrewer7372]

Stuck ptt switch? If it's on the captain's side: press another "mic selector" button on the captain's asp. Now the fo will tx to ATC and both pilots can still rx. When you select a new option on the mic selector button make sure it is something not used: like vhf-3 or hf...don't select PA. That might be embarrassing.

[@kd5you1]

One thing that the ATC doesn't understand is if the 757 has a stuck mic then they can't receive anything... at least on the same frequency.

[@Rob2]

It really amazes me how bad the radio operating practice is on services like this. It was the same at the emergency services (police etc) back when they used such a system. I would think a 5-minute discussion during their training could explain them how the system works and why it is not useful to try to talk to someone who has a stuck mike, but it is very common.

[@timbrwolf1121]

I don't know if it's the same on planes, but as a HAM radio operator I would have lowered my power in a situation where my mic was stuck and stepping on other transmissions

[@JonathanCullifer]

You typically can't lower the power in this case. About the only option is to power off the radio.

[@iVince905]

Smiley1701 it still doesn’t disregard that light signals still should come when the aircraft is in flight. It’s icao standard.

[@efoxxok7478]

I know this is going to be controversial and someone’s going to flame me, but here is my take on this. First of all I am qualified to critique this as I have 3 years experience as a controller at Chicago center, and 44 years as a pilot. Controller did realize early on who had the stuck mic, however his response was somewhat slow. Having experienced stuck mics on numerous occasions I can say with certainty telling that aircraft WHILE their mic is hot will never do any good. The moment the controller realized which plane it was he had 2 ways of resolving the situation. Both were attempted I. This case, but much time was wasted. Asking company to send an ACARS message is likely the quickest as most carrier pilots don’t monitor guard at this point. Either way, any message that reaches the pilot should be clear that HE has the stuck mic. But what was more disturbing is the lack of proper trouble shooting by the pilots. Each plane is equipped with at least 3 radios each with 2 freq selectors. If you cannot reach anyone on one radio you switch to another. Like this Hey we can’t hear anyone on this freq anymore, let’s use this radio and try a different known freq, like the last one we were on. Oops that didn’t work it must be our radio, let’s use the second radio on the Freq we were on, but make sure the first radio isn’t set to that freq. Problem solved In this day and age it is impossible to have a radio only capable of transmitting on a single freq. even more impossible to have 3 radios and only on works on only a single freq. this should have been resolved much quicker and cleaner than it was.

[@drmayeda1930]

You have 3 radios but do you have 3 mics? If the mic itself went out, changing radios won't do any good.

[@selftrue670]

I completely concur with this assessment. 1) determine the errant radio (forget the mic) . 2) . Shut down said radio and use another radio. Should take all of 45 seconds to isolate then replace.

[@tech-rich]

If it was just a stuck transmit button switching to another radio would have probably produced the same problem. It sounded like the male pilot that was having the problem, they seemed to know this as you can hear them tapping the mic and clicking the button. I'm presuming that there isn't an easy way to for them to disconnect the transmit button. As you say, a standby radio with a microphone separate from the intercom system would at least allow communication.

[@carolag1936]

The pilots definitely knew that they had a hot mic. If you listen at 1:22 in the video, you hear one of the pilot say "It's stuck. We have a hot mic. How does that happen?". For some reason they couldn't fix it and they had a stuck mic on 125.7 for 10 minutes. After that they also had a stuck mic on GUARD but even so they could still hear the controller. They did say that they tried other frequencies, and I'm guessing different radios, but could only hear anything on 121.5. The controller did try to reach the aircraft with the stuck mic on the frequency, for some reason everyone always do this, but apart from that he did quickly changed everyone else to a different frequency, heard 1:51 in the video, so it was only AAL2234 left on 125.7. He did also try GUARD but used the wrong callsign. I have no experience or knowledge but to me it seemed that the controllers did everthing they could and I'm guessing the pilots did to, as I'm sure it can't be a fun situation to be in New York with no communication.

@UCr-0qDJ4BbQvSMSqD0-lH4A - Yup, I fully agree with you

[@davidrestrepo3721]

Someone correct me, but if youre on an ifr flight plan (which is required by airlines) cant you still continue to your destination or clearance limit under 7600? Is that not what AVEF is supposed to be for? Did they have to turn back around?

[@andij605]

not really, you gotta "check out" and "check in" in each sector. get your landing clearance, all of that. it happens from time to time that you get your military fighter jet escorts if you go silent on the radio for too long

[@John_Be]

Forgive my ignorance if the plane was around 3,000-5,000 AGL couldn't they just call operations or the tower on a cell phone from the cockpit? Then they switched to 7600 they figured it out the radio was useless.

[@111himan]

Its near impossible to get a cell signal in the air under the right circumstances, the towers are aiming the signal toward the ground, not the sky. Ive flown in small airplanes, you lose signal the moment you get up in the air, after around 200ft which is where most towers reside

I kind of have a hard time believing how in 2020 air traffic is still relying on technology that can be completely blocked that easily. There has to be a better way

[@tgm9991]

I don't see it changing anytime soon I can imagine it would be stupidity expensive to upgrade plus it works most of the time so it's not worth the bother. Also digital radio which everyone else is upgrading to wouldn't work in aviation when the signals poor on those radios it's worse than the current ones.

[@kerucutgaming2216]

Digital signal such as cell phone can be blocked also. Your phone actually taking turns with other phones talking to the cell tower. So does when the cell response. This is also the same as WiFi, only one device can talk at a time on a single frequency. This is the weakness of wireless communication. Hence high bandwidth communication is done through cables.

[@Qwertworks]

@@kerucutgaming2216 well yes, but it feels like it would still allow for parallel communication of more than one person. Whereas with current radio one plain with a stuck mic kinda renders the entire frequency useless … idk. It just seems very unsafe to me.

[@kerucutgaming2216]

@@Qwertworks digital also have problem of abrupt failure though. Just like when conversing on Discord, Zoom, Teams, etc, one time it's good the next second it cut totally. On analog simple radio like this, the fallout is more gradual. You can hear the signal get worst over time. Digital signal also have significant delays, while analog is almost instant. That said, it's one of the safest form of transport out there. So the parties involved do know what they're doing. When a new technology arrives that fit the purpose, I'm sure they'll use it.
