@@RLTtizMECalm yourself and try being more civil to people. You’re wrong, by the way. There’s plenty of examples on the internet of pilots not using ‘mayday’, which caused confusion that had negative consequences to the outcome. It doesn’t take long to Google them. The point is that ‘mayday’ is the international standard, written in all the guidelines. The intention being that the single same word is used by every pilot, therefore erasing the possibility of confusion or uncertainty. If everyone is using their own word - however obvious that word might be - it still has the potential to cause unnecessary delay and confusion by the people you are in contact with. I understand that of course in a stressful situation, people can forget for a moment what they should actually be doing, but it should be infrequently. If an ATC is working a heavy traffic area for example, there’s plenty of times there’ll be blocked mics or multiple communications at once. Everyone saying whatever, can easily get lost amongst that. But an ATC ahead their ears trained for that word ‘mayday’, meaning that if they hear that among the same confusion, it will still stand out above every other word. Not only that, but ‘emergency’ can be used in several context. I can think of multiple comms videos recently posted where the word was used, but it didn’t mean that plane needed priority and to get straight on the ground. Your urgency to berate another poster, meant that you didn’t slow down to think that there’s an actual official reason why ‘mayday’ was adopted and why people should avoid just using whatever pops into their head. No matter what the industry; not just aviation; instructions are made for a reason. That’s usually because mistakes were made before and lessons were learnt. And the point of everyone following the very same print is so that everyone is ‘singing from the same song book’ as it were. I re-iterate, this gratefully minimises and has the potential to completely remove communication that could cause delay and inevitably cost lives. This is also a great example of why things that ought to work well, can come unstuck. You can have everyone following the rules and then someone comes along and decides they’re going to do their own thing - even though everyone else has always been doing the other thing - then guaranteed will blame any resulting consequence on everyone else but themselves. If people just did as they were told, there’d be no misunderstandings, no discrepancies and less misunderstanding. You talk about looking for a problem where there isn’t, when in actual fact you and the people who think like this, are the very problem that didn’t need to be created in the first place. It’s called ‘going rogue’ for a reason. And it’s unnecessary. No need for you to shout at folk in capitals, just try having a civil conversation! 🙄

So frustrating that various ATC centers cannot pass along answers so that overworked emergency crews don't have to answer same question three times.

Masks probably didn’t deploy because the cabin didn’t reach 14k’. The pilots can manually do it from the cockpit. Nice job crew….I fly this plane for the same carrier and hadn’t heard about this incident.

When the plane communicating with you has alarms going off I think its safe to say they're having a rough day.

Sincere thanks to all of those who have commented. Without your knowledge of aviation, I would have been left with no answers. I was a passenger on this plane, seated in the second to last row in the back. I heard the initial "pop" (if you will), followed by the rush of cold air previously described. There was notable distressful movement and audible gasps heard from the galley that spread quickly to the passengers. Terrifying. After our descent, to which Im guessing was at the 10k goal, a second ICE cold blast filled the plane, fogging the windows and I could se my breath. With no mask deployed, believe me it was somewhat comforting to see. The air was much more ferocious and four times as cold. Out of my depth, so a question question for the experts: Since the masks didn't deploy and the seepage (possibly) subtle allowing the plane to hold pressure, was this the moment we had lost all pressurization? Also, being so close to the compromised area as I, and the attendants were, were we more directly impacted by the loss of oxygen? The attendant quickly put on her mask. She told me afterwards she was having trouble breathing as was I. Could have been panic, possibly. Not sure. Any thoughts would be greatly appreciated. Also, If any of my fellow passengers read this, I truly hope you are all well one week later. My heart is with you all.

The 2 pilots have their own masks in the cockpit which they were able to put on. The masks should have dropped in the back. If there was a hole of seepage of air in the cabin the the outside, that definitely would be the cause. The airplane has a system that keeps pressurized air in. The plane also can pressurize some air from the engines. BUT. They can’t produce enough air to account for even a small hole or crack. The airplane inside can be safely pressurized from ground level up to 10k feet. This has plenty oxygen and nothing uncomfortable. But when there’s a hole, the pressure in the cabin gets leaked, and the outside air and pressure with no oxygen comes in. You had trouble breathing because there’s no oxygen. Being so close to the incident may have had an impact in you or the FAs breathing more than others, but probably shouldn’t have as air moves and circulates quickly. Hopefully this answered a few questions… Let me know if you have any more. Praying for all passengers and hope nobody was negatively impacted.

You mean the oxygen mask didn't drop down on you all in the passenger cabin?

@MatthijsvanDuin

Жыл бұрын

A rapid pressure drop causes an equally rapid temperature drop as you noticed, so that's indeed what you'd expect. At 10,000 ft there's enough ambient pressure to not require oxygen masks, which is why they descend to that altitude if there's a problem with pressurization. This also means that at that altitude the oxygen masks will not drop even if plane completely depressurizes, which it sounds like it did; the fact the oxygen masks never dropped simply means you were never in any danger of hypoxia. Trouble breathing might be due to cold or panic, not lack of pressure/oxygen (which wouldn't cause such a symptom in the first place, it would feel like you can breathe normally but you just get giddy/lightheaded/stupid and then pass out.)

@MatthijsvanDuin

Жыл бұрын

@@Im_Wolfyy You've got quite a few things wrong. The "system" that keeps pressurized air in is just the fact that the airplane is a pressure vessel, though it always has leaks and also intentional openings (controllable by valves) since you _want_ air to constantly escape and be replaced by fresh air from the pressurization/airconditioning system, which can pump very large amounts of outside air into the cabin (typically using "bleed air", compressed outside air taken from one of the compressor stages of the engines). A small hole or crack is not going to result in loss of pressure, it would need to be fairly substantial. The air at high altitude is no different from the air at ground level, it just has low pressure. Up to 10k feet however the pressure is still sufficient to not require pressurization at all, you can just breathe the outside air there. At higher altitudes you may after a while start to get hypoxia because the "partial pressure" of oxygen (air pressure multiplied by the percentage of oxygen in air) gets too low; the lower the partial pressure, the faster you'd get symptoms. These symptoms however do not include "trouble breathing", you can breathe just fine, it's just not getting you enough oxygen, which doesn't really cause discomfort or distress, it just eventually incapacitates you. The feeling of "air hunger" you get when holding your breath is not caused by lack of oxygen but by build-up of carbon dioxide, which doesn't happen in a depressurization scenario since you continue to exhale carbon dioxide normally.

Two packs on two independent separated pneumatic systems failing at the same time is highly unlikely plus there is air supply for pressurization from the APU [ Auxiliary Power Unit ]. Most likely a containment problem from loss of control of the outflow valve or a structural leak. Pressurization failures does not always lead to 10000 ft Decents unless they are uncontrollable, Use all resources different modes of operation and monitor the differential pressure, cabin altitude, and climb rate.

I watched this video and ATC did a good job when AA329 suffered a serious accident of cabin depressurization. Although the crew did not report the intention after Shouting MAYDAY, the crew would have been busy at that time, such as executing various checklists and stabilizing the aircraft. But the intention of AA329 to be heard by the same frequency group is important for the ATC's next command. Even though AA329 says they're making an emergency descent to 10,000 feet. Later, ATC took the initiative to provide the weather conditions of the airport they were going to divert instead of waiting for the crew, so that the crew could decide whether to land at the diverted airport or return, that is, the crew had more time to make the decision whether to return or not. It would have been better if the crew had reported the intention directly after Shouting MAYDAY, but in that case it was normal not to report directly. For example just like MAYDAY MAYDAY MAYDAY AA329 DIPRESSUREIZATION EMERGENCY DESCENT is better

It is interesting that the masks in the cabin did not deploy. We lost both packs in a A-320 years ago at FL350 and did a high-dive into KDSM. Our cabin masks, also, never deployed. What surprised me is that, while the captain was going through his drill of donning his O2 mask and initiating the descent, I noticed that the cabin altitude did not climb one single foot. In fact, I soon told the captain that he was going to have to slow his rate of descent, or else we would overtake the cabin altitude and run the risk of too great of a negative pressure situation. I ended up having to switch to manual pressurization and raising the cabin altitude first, then gradually lowing it in order to avoid landing with the cabin still pressurized. I had my O2 mask in my lap the whole time; I never had to put it on. It sure surprised me that the loss of both packs at the same time would not negatively affect the cabin pressure - at least on that particular airplane...

The SWA crew sounded like a couple of calm veterans executing a routine drill. These guys on this American flight sounded like they were on the ragged edge of full on panic......and there wasn't anything wrong with the engines or airframe, they just lost pressurization and needed to get down to 10kft with some O2 masks on. My impression is of a young, inexperienced crew and certainly not ex-warfighter Air Force pilots as many used to be.

No difference. Some of the other comments seem reasonable. There was a slow leak (for lack of better term) that triggered a cockpit alarm but the cabin altitude hadn’t risen enough to trigger masks. The flight crew initiated the emergency descent immediately.

What is it with the recent American Airlines flights between these two cities? There's this flight that resulted in an emergency declaration (loss of pressurization) and return to Miami and the more recent flight from New Orleans to Miami that resulted in an emergency declaration (fuel leak) and return to New Orleans.

How long does the the cabin pressure take to get equal to outside pressure when pressurization stops? If it’s not explosive decompression it can’t happen right away. Right?

No, but there's no way of predicting one way or another. A small leak can easily become a huge gaping leak in no time at all. If you have any notable loss in pressurization, then you have to assume the worst and lose altitude as quickly as possible (within safe operating parameters of course).

There's a reason why it's aviate, navigate and THEN communicate. Pilots were doomed in workload and they were asked silly and already answered questions. Questionable controllers's work.

That's procedure. That way you eliminate asking the crew who is busy the same questions and eliminates frequency congestion. Also, if you know the crew is busy with a pressurization problem, leave them alone till 10,000 or below. You still have plenty of time to get all the information you need.

The pilots have MUCH to do in the case of an emergency and ATC's curiosity about their situation is far less important than assessing the issue(s) with the aircraft, going through the checklists, identifying diversion airport, etc.

What would the impact be on a potential rescue if the passenger masks had deployed? I’m assuming something to do perhaps with an oxygenated environment

@chuckschillingvideos

Жыл бұрын

Basically nil. There is only about 15 minutes of passenger oxygen on board - you only need enough to get down to 10,000 feet where normal respiration can occur. Any more oxygen than that is just unnecessary weight (for the container, not the 02 itself) and, of course, a potential safety hazard.

Just because the pressurization 'failed' doesn't mean the cabin altitude rose above 14500'. There would be residual pressure and the outflow valves would probably be closed. They would be down to below 12,000' in less than 4 minutes which is sufficient. If it was an explosive decompression, they would probably have said so the pax masks would have dropped but, it didn't sound like they had their masks on initially which you would do or you would be unconscious and so would the passengers. Interesting... good old Boeing eh? LOL

Another fine example of controllers not being able to STFU when working an emergency. It couldn't have been clearer that the pilot on the radio was in task saturation, and really needed to concentrate on the flight deck instead of the controllers *asking the same questions over and over again*. How about we let them fly the plane, and only ask for what we need to do our jobs (separate from other traffic). Let the pros in the cockpit analyze, consult with company, brief passengers, make a plan to mitigate *their* emergency. It's not unlike issues that LEO's have when faced with a chase. You spend your career getting rehearsed on fake emergencies, but only face real ones occasionally. All of your adrenaline kicks in, but the best response is "cleared as requested, let me know if you need more". All of the ancillary information (hazmat, overweight, souls, equipment, hold area, high speed etc etc.) will come out after things calm down. I have zero understanding of why dropping masks might be so important to ATC that they asked several times about it. I also don't understand how details were clearly not being shared to the next sector, starting the question parade all over again.

Knowing how many ambulances you need is a job for that cabin crew after they’ve levelled off at or below 10,000ft and they are able to take stock of the situation in the cabin. That’s also the time to extract information from the pilots, not whilst the rapid descent is ongoing.

I'm guessing "overweight landing" refers to not using the expected amount of fuel before landing because you had to land earlier...?

ATC was highly poor during this. Outside of the Mayday call, they kept stepping on the emergency aircraft with stupid questions that had already been answered and were not even remotely relevant. The masks failing to deploy is an issue though, at 32000 feet they should have done so automatically. But they got down quickly enough that the pax might have just had some sparklely vision and some shortness of breath.

Loosing pressurization doesn't necessarily mean the passenger cabin got to the altitude that would automatically deploy the masks.

Nicely done by the crew and also nice managed. Yes memory items including deployment of the pax oxygen system manually if the cabin is out of control. But if the PM was able to control the cabin in manual mode and close the outflow valve. Then the memory item stops there. IF the cabin is uncontrollable PASS SIGNS…ON, PAX OXYGEN SWITCH…ON Go to the Emergency Descent checklist……. (REF.QRH) Very poor situational awareness of the ATC if the timeline holds. Machinegunning the poor crew with questions not necessary before your mayday is over. In the end the commander can decide what he deems necessary for the safety of the airplane and passengers. That includes NOT deploying the Passenger oxygen masks. (If you have an engine acting up. He(she) may also choose NOT to shut it down and just keep it idling”ref.FCTM and QRH”)

OMG😮

Why in this day of information overload would a controller need to ask souls, hazmat and fuel onboard? You would think this information would be readily available and definitely not needed immediately when the aircraft is over 100 miles out from MIA. Then the information was not passed along to the next controller.....why?

@gutschke

Жыл бұрын

This is pretty standard in emergency situations. You are likely going to see the same thing in hospitals or when dealing with first responders (e.g. fire department). In stressful situations, it is common for people to filter out "unimportant details" and this is even more true if we are dealing with oxygen deprivation. Unfortunately, what our brain declares to be unimportant could actually be quite critical (e.g. passengers suffering from hypoxia this very moment). So, emergency personnel always ask. You can't rely on the pilots to volunteer any of these details if they are impaired. And in this recording, you can quite clearly tell that the pilots were overwhelmed. They forgot to follow up with ATC and they mixed up their own call sign several times. It was noteworthy that ATC gave them more detailed and unambiguous instructions than what you'd normally hear on the radio. Lots of redundantly repeated information. I am sure this was very intentional. As to your other question, in an emergency, you don't rely on previous information collected by other parties. It's always possible that it wasn't passed on correctly. The cost of asking again is cheap, but the consequences of forgetting to pass on information is potentially fatal. Of course, you still pass on information where possible and if there is a conflict between older and more recent records, that would cause you to follow up. It could be a clerical error, it could be a genuine change in conditions, or it could be an indication that the pilots are impaired or incapacitated. A lot of these things sound ridiculous when you observe them. But it's all for good reason. Also, these type of videos are confusing, as silence is trimmed. So, it sounds as if ATC was constantly going on about the same thing. In reality, there probably were significant gaps.

That information needs to be confirmed. Any slight changes in weight can have devistating consequences if not accounted for when planning approaches, etc. Fuel on board and overweight status must be verified because it cana affect descent and landing, and the aircraft is only rated to land within a specific range of weights. If it's overweight there is potential for catastrophic failure including the aircraft breaking apart on landing due to the excess forces created at that time, causing loss of life and property. Overweight landings are very dangerous in a number of cases. Some are ok if it's not too far above and if other measures can be taken, but the potential for the collapse of landing gear is high resulting in the aircraft slamming into the ground which as you can imagine is not what anyone wants. The further out this information is know the more can be planned including burning off excess fuel to reduce weight. Burning off fuel isn't instant. Think about how long of a flight it is. The amount of time it takes to get to that destination is going to take alot of fuel. Fuel is heavy. You can't just turn a plane around and instantly land in many cases. :)

Something many folks may not realize is that, in the event of a cabin depressurization, the worry isn't about the depressurization itself (no one is going to suffocate) but that the airframe may be structurally compromised and that the depressurization is a symptom of a much larger and more dangerous issue. This may or may not have contributed to the pilot's decision to return to Miami, which had better weather than the initial airport he had mentioned diverting to, since thunderstorms can cause turbulence which could possibly put added strain on the aircraft.
