It's always a pleasure to listen to an excellent job on everyone's part. I just can't understand how, with our modern technology, the radio communications have not improved. Blocked calls are bad enough.
Isn't it bad idea to give a clear to land to the #2 plane? What if more radio gets blocked and say the RF doesn't get off the runway? Why wouldn't they give proceed but not cleared until you hear from us? Seems like that was a bad idea.
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.
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.
@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".
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.
@@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.

@Jo Fox..Yes, it may seem scary, but if you stick to your planned departure procedures, we will anticipate your actions and clear the way.

These guys are incredible. I’ve watched several of these and out of all, a radio failure is by far the scariest. Not only did tower handle it but he stayed two steps ahead every time. The guy is a genius. You know which one im talking about!
Wow , amazing lesson, i tought that you have to completly forget about fly and concentrate all the crew attention over the radio issue, and , in some cases , ask to passengers for help. You are a wise men.
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.
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.
@@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.
I don't know if it's my overly cautious nature, but when I was flying light aircraft, I ALWAYS carried a handheld radio and a handheld garmin with altimeter, even had the gps programmed with all airports in country. My instructor and I once did a full 200km flight with only these to test effectiveness (covered instruments, not off), worked brilliantly as a backup - completed the full flight on them.
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. If I do need it... glad to have it.
@@Yotanido You can also use your phone if not too high. Keep the tower numbers with you at all time. If bad reception, use SMS and text a friend that can relay.
@@Yotanido What if you jumped on a Radio Operators License? I have an Extra class license, you pay $10 here and keep them for life. Technically its a Ham Radio License, but still it would justify carrying a radio even if the Air frequencies are outside the Ham bands. My radio can transmit on Ham bands, Air bands, M.A.R.S and more so it would be hard for them to ping me for it. Is that a possibility for you?
I love how they actually use 121.5 like they’re supposed to and then ATC tries to get them to switch to other frequencies knowing they can’t be reached on any other frequency.
More commonly known as "jamming" in this context. It is one of the downsides of the simple analog radios used in aviation and a big yawning vulnerability in the system.
@@DaveWhoa I'll tell you a story about when I was in the Navy. Stationed on a supply ship, got orders to head out into the Atlantic to do a hide and seek war game with some destroyers and a few aircraft. We were the rabbit and they were the fox. We had a real smart Electronics Tech on the ship and he decided to turn our transmitters into high powered jammers. He had the carpenter make giant reflectors out of 2x4s and aluminum sheeting and he placed them right next to the 20 foot tall antennas, each pointing in a different direction. I'm assuming he increased the power on those transmitters, but I don't know for sure. Anyway, he started broadcasting AC/DC Back In Black album nonstop. Apparently, it worked because about an hour later we get a sat message from the fleet admiral back in Norfolk telling us to knock it off. We never got picked to be the rabbit again.
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.
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.
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.
@@rivalarrival Thanks for that. I was struggling to understand how this situation could occur with what I assumed was multiple radio redundancy. Sounds like it was an unusual enough fault to break that redundancy.
I love how the priority was also on minimizing disruptions to the operations, and they were already vecoring in the next two aircraft to land before the emergency aircraft was even 5 miles out. And everything worked out.
Well remember, it was the CREW who figured out how to talk to the TOWER, not the other way around. the crew was dealing with an equipment failure but they knew their jobs.
No joke but I remember hearing the story of a pilot being vectored in for a landing in IFR conditions after declaring a 7600 squawk using text messages! It was a GA aircraft.
@@spicyweasel they do have text messaging system. It's called ACARS if I'm not mistaken. You can hear in the video the controller ask other plane of same airline to send them ACARS messages. It is mostly used by companies to communicate with their pilots.
@@kerucutgaming2216 Yes I do know about ACARS. But in the situation I described earlier the pilot had to use his cell phone and descend to a better altitude to SMS the tower. I found the video for you. th-cam.com/video/UQtvi1ijPQ4/w-d-xo.html
I've had a similar problem flying another aircraft type departing into London TMA. We solved it by selecting to put the stuck mic to transmit on 123.450 which is usually a shit-chat frequency while monitor our normal frequency on VH2. And when we had to transmit we just selected the stuck mic back to original freq. I don't know if this would've been possible on the 757 or if this was the problem for them but for a stuck mic it should work on most aircraft types.
That's exactly how they handled it, and explains the stuck mic reports they got near the end. It took them a little time to get the transmitting radio off frequency.
This makes you see how weak is the system by a tiny failure, but I'm glad to know that there's training of all sorts. We had here in Argentina a few months ago a saboteur with a handheld radio impresonating ATC, luckly nothing happened.
Cesar Queti the fact that they could still vector the emergency aircraft and all others in the vicinity is actually a testament to the strength of the system. Notice how they didn’t even have to use light signals to guide him in, and had plenty of resources to maintain contact with the aircraft despite a major radio failure.
I hadn't heard about that one. I probably wasn't subscribed to the channel yet and only watching a few here and there. I'll have to see if I can track it down. Update: found it! th-cam.com/video/7WKZNGisSqM/w-d-xo.html
Just another example of how talented commercial pilots and controllers are. This is a nightmare scenario and it was pulled off safely with just a brief interruption of commercial traffic. Well done to all involved
This is one of the most intense videos I've seen so far. Just wow!! The way ATC handled that was incredible. Great job all around. That was seriously scary
This radio failure effectively jammed the tower & departure frequencies. The sudden cease of communication, something so natural as expecting a light to turn on by pressing a light switch, is a frightening prospect that one tends to forget.
WOW...talk about tough conditions, this really mucked things up......Glad turned out Great..Could have had a different ending for sure....great work by everybody...Kudo's
I do like how they kept telling him he had a stuck mic well after he and everyone else acknowledges he has a Radio Failure... so even in real life we have those annoying pop up messages.
Great and timely video, as always! Just curious, was and is there any communications recordings available about Delta 1425 (the one that lost the engine cone mid flight from Atlanta to Baltimore)? I see very little mention of it anywhere, except the cabin videos.
Very interesting to see an hear how such an emergency is handled. I just wondered, do'nt they have an spare portable radio in the cockpit, so if the onboard radios fail, they can used that one? Since it will be used very seldom one should make sure its battery is alsways fully loaded though.
KJFK TWR: "[...] I'll let you know if he doesn't get off the runway but, wind 040 at 5, runway 4R, cleared to land." Am I the only one who thinks that this is fucked up? There is traffic in front of him so the runway is NOT clear, and he says himself that he doesn't even know if the emergency aircraft is going to vacate the runway on its own! And yet he gives a landing clearance, unbelievable. What if the approaching aircraft suddenly has a radio failure too or switches to the wrong frequency by accident or ANYTHING on short final and can't hear TWR while TWR tries to instruct a go-around? Add bad visibility and boom, unnecessary crash because the USA had to be special again. You should never make your radio a safety critical component. Because as we can see here, it can fail anytime. Correct call would've been: "[...] I'll let you know if he doesn't get off the runway but continue approach runway 04R." That way the pilot is going to fly a missed approach automatically in case he hears no clearance for whatever reason. Clearance should only be given if the runway is CLEAR. This makes my blood boil because this is my LIFE they have in their hands while using dangerous practices and bad phraseology everytime I fly into their airspace.
Seems like an interesting case study in the failure of a complex engineering system. Notwithstanding the fact that it all turned out ok, are there any lessons to be learned from this that might change protocols or aspects of system design?
Using a 1930's radio frequency system for modern air traffic control. Advantage is that everyone hears every transmission, when everyone is following standard radio procedures. Disadvantage is that one stuck mic can ruin everyone's day. Some Electrical/Electronics engineer might have an idea for how to update the system, but it would not be cheap. It would mean updating radios in every ATC center, control tower and aircraft on the planet.
@@fhuber7507 I am one of those electrical engineers, and also a pilot, and I very much prefer human voices over analog AM for reliability and robustness in conditions that make digital radio solutions fall over quickly.
@@VASAviation Espero que no. I'd much rather deal with AM radios under poor conditions like stuck mic than the same than the same with any digital radio system. Y digo esto como ingeniero eléctrico y piloto.
I know at my job some microphones timeout after 60 seconds and will make a loud audible 1 second "beep" if it does ever timeout. I wonder if something like that can be implemented in airplanes.
So, each radio voice transmitter on the aircraft should have a tiny LED installed in the glareshield, directly in front of each pilot's seat. If any light is on, you are transmitting. Start checking hand mikes, audio panels, control wheel switches for PTT. If the lights are distracting, add a ten-second TX delay. Or integrate the same function into an EICAS function, or equivalent.
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.
5:42 AAL2234: "This is the only freq I'm copying anybody on" Then... 7:37 I wonder if JFK TWR could have used Guard instead, since nothing came through anyway.
@@VASAviation Honestly, not really. I imagine there would be some interesting conversation between ATC and surrounding aircraft when a plane goes NORDO. Still really neat video, especially in this specific instance!
If anyone is still watching this video, why is there no way for ATC to communicate to a Plane through some type of messaging or vise versa when there is RF? Thanks!
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!
I just watched a video yesterday about the things every pilot should have in his bag,............. one of those items was a hand held radio, in case of a radio failure. They are only good for a couple of miles, but better than nothing.
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.
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.
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.
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.
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.
Why the hell did they clear the American 276 for landing?? If 276 was unable to go around for some reason and the RF aircraft didn't clear the runway, it could've been a fucking disaster..
No. Most transport-level aircraft radios generate sidetone (the audio you hear back as you transmit) by activating the receive chain simultaneously. This is also common on ground ATC systems that use multiple voting receivers, they activate a receiver at a different site as you transmit. It is designed like this to give you confidence that your transmitter is working properly, if it's not you get a noticeable silence. If conditions are right, you can hear heterodyne squeal or even a message.
I guess, why not just get a flashing "FOLLOW ME" car in front of him? Once a stuck mic happened here in Sweden, the airport and planes like semlessly went over to a reserved spare frequency and operations went just about normal. Do they not have that over there?
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.
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
I don't know about this, but it seems that having a backup system of communicating via text would help when the radio is out. Or would the text messages be on the same frequency as the radio?
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.
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.
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.
That’s incredible, not so much just the RF but it occurring in one of the worst airspace’s in the world for it to happen and at the worst possible time and altitude. Scary stuff for real.
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.
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
How do you get all of these!? I have radio failure and general emergency calls set to notify me on flight radar 24 but can’t seem to get any alerts from North America
Just out of curiosity, CPDLC allows controllers to send pilots text messages directly right? Why is this not the standard and voice only a backup? Is it just impractical to ask pilots to text and aviate at the same time? Seems kind of dangerous one broken mic can prevent anyone on the frequency from communicating at all. Maybe ATC sends messages through CPDLC and pilots reply by voice? That way ATC can still provide instructions even without pilot confirming receipt of message in a similar situation? Just seems weird to me in 2021 we don't have a better system than every plane in an area being on a communal frequency that only allows one person to talk at a time.
@@algrant33 CPDLC is apparently standard or oceanic flights that are too far out for decent VHF reception. I'm not saying voice itself is bad. I'm saying not being able to talk because some other plane is having equipment failure and they have their push to talk stuck down seems dangerous.

Wow , amazing lesson, i tought that you have to completly forget about fly and concentrate all the crew attention over the radio issue, and , in some cases , ask to passengers for help. You are a wise men.
I’m sure they wouldn’t have asked you to help them.
@@flyerdon3116 sure. They would ask to you wise men, and you will wisely say " fly the airplane" . A truly ray of light over the situation
@@rastachicagomataderos There have been multiple crashes due to pilots forgetting to fly the plane while troubleshooting issues.
Hey, where did that spring fly off to? It belongs right here in the mike key. Help me look for it.
7:46 An emergency going on and someone's partying in the background o;
poor AAL954 indeed lol. got the wrong guy!
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.
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.
@@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.
I don't know if it's my overly cautious nature, but when I was flying light aircraft, I ALWAYS carried a handheld radio and a handheld garmin with altimeter, even had the gps programmed with all airports in country. My instructor and I once did a full 200km flight with only these to test effectiveness (covered instruments, not off), worked brilliantly as a backup - completed the full flight on them.
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. If I do need it... glad to have it.
@@Yotanido You can also use your phone if not too high. Keep the tower numbers with you at all time. If bad reception, use SMS and text a friend that can relay.
@@Yotanido What if you jumped on a Radio Operators License? I have an Extra class license, you pay $10 here and keep them for life. Technically its a Ham Radio License, but still it would justify carrying a radio even if the Air frequencies are outside the Ham bands. My radio can transmit on Ham bands, Air bands, M.A.R.S and more so it would be hard for them to ping me for it. Is that a possibility for you?
@@Xanthopteryx good idea
@@Yotanido
That sounds like a law to be proudly violated.
I love how they actually use 121.5 like they’re supposed to and then ATC tries to get them to switch to other frequencies knowing they can’t be reached on any other frequency.
Highly skilled pilots and ATC. Crisis averted!
this is effectively an inadvertent "Denial-of-Service attack"
More commonly known as "jamming" in this context. It is one of the downsides of the simple analog radios used in aviation and a big yawning vulnerability in the system.
@@ghstark and this was just accidental - makes me wonder what sort of fun antics the electronic warfare planes like the Growlers can get up to lol :)
@@DaveWhoa I'll tell you a story about when I was in the Navy.
Stationed on a supply ship, got orders to head out into the Atlantic to do a hide and seek war game with some destroyers and a few aircraft. We were the rabbit and they were the fox.
We had a real smart Electronics Tech on the ship and he decided to turn our transmitters into high powered jammers. He had the carpenter make giant reflectors out of 2x4s and aluminum sheeting and he placed them right next to the 20 foot tall antennas, each pointing in a different direction. I'm assuming he increased the power on those transmitters, but I don't know for sure. Anyway, he started broadcasting AC/DC Back In Black album nonstop. Apparently, it worked because about an hour later we get a sat message from the fleet admiral back in Norfolk telling us to knock it off.
We never got picked to be the rabbit again.
@@operator0 hahahaha that's beautifully brilliant! :)
@@operator0 Haha, awesome
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.
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.
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.
@@rivalarrival Thanks for that. I was struggling to understand how this situation could occur with what I assumed was multiple radio redundancy. Sounds like it was an unusual enough fault to break that redundancy.
I love how the priority was also on minimizing disruptions to the operations, and they were already vecoring in the next two aircraft to land before the emergency aircraft was even 5 miles out. And everything worked out.
Well remember, it was the CREW who figured out how to talk to the TOWER, not the other way around. the crew was dealing with an equipment failure but they knew their jobs.
thought it odd that they already cleared the aircraft behind for landing... maybe just say "continue approach" in this situation?
Should’ve just sent the pilots a Facebook chat message!
AOL Voice: "You've got mail!"
No joke but I remember hearing the story of a pilot being vectored in for a landing in IFR conditions after declaring a 7600 squawk using text messages! It was a GA aircraft.
@@spicyweasel they do have text messaging system. It's called ACARS if I'm not mistaken. You can hear in the video the controller ask other plane of same airline to send them ACARS messages. It is mostly used by companies to communicate with their pilots.
@@kerucutgaming2216 Yes I do know about ACARS. But in the situation I described earlier the pilot had to use his cell phone and descend to a better altitude to SMS the tower. I found the video for you. th-cam.com/video/UQtvi1ijPQ4/w-d-xo.html
Nicely done by everybody involved..... controllers, NORDO aircraft, and other aircraft trying to assist. Well orchestrated across the board.
I've had a similar problem flying another aircraft type departing into London TMA. We solved it by selecting to put the stuck mic to transmit on 123.450 which is usually a shit-chat frequency while monitor our normal frequency on VH2. And when we had to transmit we just selected the stuck mic back to original freq. I don't know if this would've been possible on the 757 or if this was the problem for them but for a stuck mic it should work on most aircraft types.
That's exactly how they handled it, and explains the stuck mic reports they got near the end. It took them a little time to get the transmitting radio off frequency.
wait, you saying pilots got a dedicated shitposting frequency?
@@mfaizsyahmi Yea offcourse! How else are we suppose to road rage? (air rage)
I was just wondering how long aviation type radios would transmit before their finals burned up.
@@kd5you1 It's all solid state. With half decent cooling, you should be able to transmit for decades
great teamwork from everyone involved getting them back down and to the gate safely!
Love hearing pilot, other pilots, and ATC working so well together. Job well done by all.
This makes you see how weak is the system by a tiny failure, but I'm glad to know that there's training of all sorts. We had here in Argentina a few months ago a saboteur with a handheld radio impresonating ATC, luckly nothing happened.
Cesar Queti the fact that they could still vector the emergency aircraft and all others in the vicinity is actually a testament to the strength of the system. Notice how they didn’t even have to use light signals to guide him in, and had plenty of resources to maintain contact with the aircraft despite a major radio failure.
That video is on this channel. Crazy to be that vulnerable too
I hadn't heard about that one. I probably wasn't subscribed to the channel yet and only watching a few here and there. I'll have to see if I can track it down.

This is one of the most intense videos I've seen so far. Just wow!! The way ATC handled that was incredible. Great job all around. That was seriously scary
This radio failure effectively jammed the tower & departure frequencies. The sudden cease of communication, something so natural as expecting a light to turn on by pressing a light switch, is a frightening prospect that one tends to forget.
WOW...talk about tough conditions, this really mucked things up......Glad turned out Great..Could have had a different ending for sure....great work by everybody...Kudo's
I love how the (co-)pilot says ''You got a hot mic'' at 1:24
"the hell is that" "how did that happen" around the same time
I lost radios on my very first solo flight away from RDU. Landed at a practice field. I was PISSED!
1:50 What ATC sounds like in Star Wars
I do like how they kept telling him he had a stuck mic well after he and everyone else acknowledges he has a Radio Failure... so even in real life we have those annoying pop up messages.
I think the idea was that, if he can hear on Guard, then he should mean he can hang up on Guard.
Sadly that was not the case.
"YOU'RE ON GUARD!" "GUAAAAAARD!"

Watching this high was a mistake. The demon voices around 2 minutes in are trying to get me
Great and timely video, as always! Just curious, was and is there any communications recordings available about Delta 1425 (the one that lost the engine cone mid flight from Atlanta to Baltimore)? I see very little mention of it anywhere, except the cabin videos.
I couldn't find anything interesting
Very interesting to see an hear how such an emergency is handled. I just wondered, do'nt they have an spare portable radio in the cockpit, so if the onboard radios fail, they can used that one? Since it will be used very seldom one should make sure its battery is alsways fully loaded though.
Nah thats not the practise..
KJFK TWR: "[...] I'll let you know if he doesn't get off the runway but, wind 040 at 5, runway 4R, cleared to land."
Am I the only one who thinks that this is fucked up? There is traffic in front of him so the runway is NOT clear, and he says himself that he doesn't even know if the emergency aircraft is going to vacate the runway on its own! And yet he gives a landing clearance, unbelievable.
What if the approaching aircraft suddenly has a radio failure too or switches to the wrong frequency by accident or ANYTHING on short final and can't hear TWR while TWR tries to instruct a go-around? Add bad visibility and boom, unnecessary crash because the USA had to be special again. You should never make your radio a safety critical component. Because as we can see here, it can fail anytime.
Correct call would've been: "[...] I'll let you know if he doesn't get off the runway but continue approach runway 04R." That way the pilot is going to fly a missed approach automatically in case he hears no clearance for whatever reason. Clearance should only be given if the runway is CLEAR.
This makes my blood boil because this is my LIFE they have in their hands while using dangerous practices and bad phraseology everytime I fly into their airspace.
Seems like an interesting case study in the failure of a complex engineering system. Notwithstanding the fact that it all turned out ok, are there any lessons to be learned from this that might change protocols or aspects of system design?
Using a 1930's radio frequency system for modern air traffic control.
Advantage is that everyone hears every transmission, when everyone is following standard radio procedures.
Disadvantage is that one stuck mic can ruin everyone's day.
Some Electrical/Electronics engineer might have an idea for how to update the system, but it would not be cheap. It would mean updating radios in every ATC center, control tower and aircraft on the planet.
Hoping radios get improved
@@fhuber7507 I am one of those electrical engineers, and also a pilot, and I very much prefer human voices over analog AM for reliability and robustness in conditions that make digital radio solutions fall over quickly.
@@VASAviation Espero que no. I'd much rather deal with AM radios under poor conditions like stuck mic than the same than the same with any digital radio system. Y digo esto como ingeniero eléctrico y piloto.
I know at my job some microphones timeout after 60 seconds and will make a loud audible 1 second "beep" if it does ever timeout. I wonder if something like that can be implemented in airplanes.
1:25 "that's a hot mic [...] how the hell did that happen?"
Wow, no one is commenting on the radio about transmitting on... "You have a stuck mic on Guard!" Ahh... THERE it is!.

@@Sarah.Riedel me to. "Sir you have a stuck mic" *[tapping intensifies]*

So we can send a man to the moon, split atoms, but have no backup for a “stuck mic.”
Shows the weakness of still using the “party channel” aspect of radios.
You'd think the electronics can be redesigned by incorporating a Time-Delay (TD) with a momentary to help reset a fully energized and stuck circuit.
" communications are pretty sh..aky right now"
So, each radio voice transmitter on the aircraft should have a tiny LED installed in the glareshield, directly in front of each pilot's seat. If any light is on, you are transmitting. Start checking hand mikes, audio panels, control wheel switches for PTT. If the lights are distracting, add a ten-second TX delay. Or integrate the same function into an EICAS function, or equivalent.
7:20 is the highlight LOL glad its handled
The only RF I've seen on a 57 was the hydraulic quantity. Refill. Cool stuff. Learn something new all the time.
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.
imaPangolin I’ve always gotten a kick out of people doing that too. ATC should know better and should have gone to Guars immediately
5:42 AAL2234: "This is the only freq I'm copying anybody on" Then... 7:37 I wonder if JFK TWR could have used Guard instead, since nothing came through anyway.
With how often I get 7600 alerts from FlightRadar, surprised there isn't more radio failures on this channel
Have you ever wondered why?
@@VASAviation Honestly, not really. I imagine there would be some interesting conversation between ATC and surrounding aircraft when a plane goes NORDO.
Still really neat video, especially in this specific instance!
God damn these controllers were really pushing tin up hill. Lucky the skilled pilots were able to find their way back to Kennedy.
I like that as a passenger on the plane, you most likely have no clue whats going on up front and this just seems like a normal flight
If anyone is still watching this video, why is there no way for ATC to communicate to a Plane through some type of messaging or vise versa when there is RF? Thanks!
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!
Couldn't the second officer make calls on his radio? I'm not a pilot but just wondering how this could happen on an airliner---no back up????
The radios are the same for both pilots. This may be a short somewhere deeper in the radio electrical system than just the push to talk switch.
I just watched a video yesterday about the things every pilot should have in his bag,............. one of those items was a hand held radio, in case of a radio failure. They are only good for a couple of miles, but better than nothing.
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.
Unfortunately that's how VHF and air band works. I think radios should be improved too (apart from ACARS or Selcal systems)
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.
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.
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.
A lot of planes already have the capability being built these days. A small LED light or a shadows or light emitted behind the COM1 logo
Maybe they could have fired a few flares from the ground?
A distinct color for the intended runway to land on?
improvised communications is a way to miscommunicate. There are allowances in the reg and in procedure to handle this.
Should be a small bright red light that indicate when you are transmitting.
There is in some aircraft
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.
As always, incredible professionalism by all involved
Why the hell did they clear the American 276 for landing?? If 276 was unable to go around for some reason and the RF aircraft didn't clear the runway, it could've been a fucking disaster..
"Somebody's got an open mic" is useless to say, no? It's not like they can hear you, right?
No. Most transport-level aircraft radios generate sidetone (the audio you hear back as you transmit) by activating the receive chain simultaneously. This is also common on ground ATC systems that use multiple voting receivers, they activate a receiver at a different site as you transmit. It is designed like this to give you confidence that your transmitter is working properly, if it's not you get a noticeable silence. If conditions are right, you can hear heterodyne squeal or even a message.
its to inform other traffic on that frequencie to double check what they hear, as to not crash because hearing the wrong massage
I guess, why not just get a flashing "FOLLOW ME" car in front of him?
Once a stuck mic happened here in Sweden, the airport and planes like semlessly went over to a reserved spare frequency and operations went just about normal. Do they not have that over there?
That's what they did
Pull the radio circuit breaker and use the handheld portable radio you should have?
Or use one receive-only, and the handheld to xmt.
They really should put a hand held radio in the cockpit for this kinda thing! surely they can disable the radios if stuck TX
I love NY ATC.
when u use headset from aliexpress)
That's a busy area to lose communication.
Holy shit, those two planes came within 1500ft of one another. That's a sphincter clincher.
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.
That's why we have squawk codes
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
Maybe ACARS but TCAS wouldnt really help
You finally zoomed in on the radar so everyone can actually see it and read it. Thank you.
I've been doing this for months
I don't know about this, but it seems that having a backup system of communicating via text would help when the radio is out. Or would the text messages be on the same frequency as the radio?
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.
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.
They got it done safely.
I actually think I was flying cross country when this happened and I heard it happen on guard
I mean he was told they have a stuck mic. Its easy to disable your radios. Sometimes is missing here.
yikes, what a nightmare, not being able to hear tower or other pilots...
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.
All aircraft should be equipped with a cellular frequency telephone in the cockpit. At least it would help when they're not over water
Great job to all!
Couldn't they use a cellphone to re-establish communication? I'm unsure how high transmission of those will go.
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.
8:29 caption problem 2x -- caption reads "straight as we can" but I hear "quick as we can"
No big deal
That’s incredible, not so much just the RF but it occurring in one of the worst airspace’s in the world for it to happen and at the worst possible time and altitude. Scary stuff for real.
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.

Dumb question but why couldn’t one of the pilots just call the ACT with a phone?
Sparta Gaming the cellular system doesn’t broadcast/receive at even fairly low altitudes.
Just out of curiosity, CPDLC allows controllers to send pilots text messages directly right? Why is this not the standard and voice only a backup? Is it just impractical to ask pilots to text and aviate at the same time? Seems kind of dangerous one broken mic can prevent anyone on the frequency from communicating at all. Maybe ATC sends messages through CPDLC and pilots reply by voice? That way ATC can still provide instructions even without pilot confirming receipt of message in a similar situation? Just seems weird to me in 2021 we don't have a better system than every plane in an area being on a communal frequency that only allows one person to talk at a time.
We don't even let people text and drive, and you want people to text and fly? Voice is synchronous and immediate
@@algrant33 CPDLC is apparently standard or oceanic flights that are too far out for decent VHF reception. I'm not saying voice itself is bad. I'm saying not being able to talk because some other plane is having equipment failure and they have their push to talk stuck down seems dangerous.
