I got to fly back from Frankfurt to Calgary on this very same aircraft (C-GITS - it had obviously been repaired). Didn't bother me because I knew the problem was never the aircraft. I had a fellow traveler from Germany who was very enthusiastic about his first trip to Canada and yet obviously a nervous traveler. I started by saying "this aircraft has a very interesting history" and then immediately realized, no, I can't tell this guy this story at the beginning of the flight. He kept badgering me but I told him I'd tell him the story after we landed - which I did. He turned WHITE! :)

@@QuintonDeLauda No, he did not do what was in the checklist, because he didn't actually read it, physically. The very first point on the fuel imbalance checklist was "Don't do this if you have a fuel leak". He did not see that, because he did not physically use the printed checklist, and just went through the motions for a DIFFERENT scenario, which he had misidentified. Reading that real, physical checklist would have brought to his attention that they possibly did have a leak, and therefore should not have being following that procedure. It's all there, in the video, if you watch it completely.

I was on that flight. Truly scary event. It was so long, that I thought about opening the door and jump the plane, and not wait to die splashing in the water. The captain made a mistake, but saved my life and the life of 300 others. Still an hero in my eyes. I will always be grateful to the captain and the crew and the control tower. I was using the crew as a reference, at a certain point I lost all hope as the cabin crew, just froze. Can’t blame them, no training in the world will be enough to deal with a situation like this. After the flight back to lisbon I never flew Air transar again. Still today, I have to have a couple of drinks before the flight, so I can sleep. As long as I listen to the engines running, I try to relax as much as possible and sleep. The worst moment I believe, was to listen the engines die, and feel the free fall...

It should be noted that the maintenance crew was reluctant in providing a maintenance release due to not having a proper maintenance standard for the hydraulic pump installation.

[@millomweb]

I had a job doing maintenance on Cherry pickers. The day I started, the depot manager gave me a 'tour' of the depot. He pointed out fire exit and alarm call points. I asked "Is the alarm a bell or a siren" . " " . "Does the fire alarm work ?", I then asked. So, on the day I started, by lunchtime I knew I wasn't going to be working there long-term. It seems the whole company was shoddy. So, beware of any access platforms plastered with Loxam or any of its subsidiaries. I carried out inspections and effectively certified equipment fit to use. I'd done one 'in advance' on condition an issue was rectified. In the manager's office, he made it clear the problem was not going to be dealt with - so I ripped up my certification there & then.

[@WestOfEarth]

Right at the beginning of this clip I was shocked that the airline had zero spare engines. If you're out of spare engines, shouldn't somebody be ordering additional ones? And long before you use the last spare engine. It seems of course that the airline itself wasn't faulted for this lack of preparation.

My family is from that beautiful island, Terceira. My parents immigrated to the USA but we’ve often returned to visit throughout my life

[@jnvqc]

​@@franciscoj7540 Actually no, the Atlantic is expanding and the Pacific retracting. Two tectonic plates can move in relation to one another by 3 ways, 1- lateral movement 2-subduction (one plate gets swallowed by the other) 3- Spreading (new land is formed with a ridge in the middle of the two). For the islands to approach the continent, a subduction zone must exist in either North America east coast or in western europe (Portugal, Spain, Northern France, and the British Isles.) Looking at a tectonic plate map there aren't any such zones. The American plate is continuous starting in the Azores and ending in the subduction zone in the west coast (California, British Columbia, Alaska, etc). The same is true for the eurasian plate, it's continuous from the Azores till Russia, Koreas, China, Japan, etc. The mid atlantic ridge is creating new ocean floor pushing the american and eurasian plate against the pacific plate, decreasing the size of the pacific ocean and increasing the atlantic. 1 to 10 cm per year. I'm from the Azores islands and I studied geology in high school. Fun fact the Azores are located in the junction of the american, eurasian and african plates. The last volcanic eruption was 60 years ago, the last major earthquake 40 years ago. Spreading plates are much safer than lateral moving and subduction. Half of my island is in the african plate and the other on the eurasian. Two of the nine islands are in the american plate, so on the other side of the ridge meaning that they are getting away from the rest. The lajes airport is also leased to the US air force and played an important role in WW2, Golf War and War on Terror, nowadays due to budget cuts it's just a gas station for the USAF. Mentour's company flies from europe to the Azores.

[@JanBruunAndersen]

About this dangerous confirmation bias... For me (working in IT) one trick that I use is to explain to a colleague - in writing, in an email or in a chat - what I think is going on and my conclusions so far. It is amazing how often I then stop myself halfway through the explanation and say "Wait... That is not necessarily the only explanation", or "How did I come to that conclusion? Which step lead me here?". If in a chat, this then is where I say "Forget that. I will come back to you"... Of course, I am usually not in the same kind of stress situation, with 200 passengers in the back and 20,000 feet of air below, but still, explaining your infallible logic often exposes the failures in it.

[@tomschmidt381]

Agree - confirmation bias occurs to all of us. The good news is that for most of us we have much longer time to discover our error then airline pilots.

[@dunbar9finger]

There's a name for that. It's the "rubber duck" technique. (Named after a particular programmer who kept bothering his co-workers for help and as soon as he started explaining it he realized himself what mistake he was making and the co-worker's time was unnecessary. Eventually they bought him a rubber ducky and placed it on his computer desk, saying "explain your problem aloud to the rubber duck first. If the rubber duck can't help you, THEN ask for help from someone else." The technique was so effective that soon everyone had their own rubber ducky and was using it.) The act of explaining it to someone else forces you to articulate your thinking step by step, which brings your subconscious assumptions to the surface where you notice them.

[@millomweb]

When you have 10 instruments measuring the temperature and one of them says it's too hot, it IS too hot - until you can prove the instrument is faulty.

Plus, he's very nice to me and says he's always interested in my thought process even if it is a bit wonky at times haha.

I wanted to go to the Caribbean to get hitched (just the 2 of us), so I did a fear of flying audiobook (with a regular book too) and binge watched aircraft investigation. Seeing how most things have been fixed so they can’t happen again and how skilled the crews are (and how few accidents there have been considering how many flights there are) really calms me down.

As a mechanic, it's easy for me to see a problem and connect the dots as to what's going on and causing other problems. One thing that I've always thought would be so helpful to pilots and flight crews is having cameras mounted on the outside of the plane in flight critical areas. We definitely have the technology to make this happen.

[@paulstimpson830]

Considering that exterior lighting would also be necessary for normal cameras to be effective in darkness, do you think thermal cameras would have helped here? As an engineer, I'm pretty sure the thermal view of engine exhaust from the leaky engine would have looked very different from the normal engine

[@DarkStar14n]

Newer aircraft do have cameras externally. Some even let passengers a look from the tail and nose ones. (Not recommended for people with vertigo)

[@Sawta]

@@DMAX-tp4pc Although there are many pratical considerations, do you think it would be fesable for something like this: Camera area is covered by metal shielding by default. In emergency situation where abnormal event has occurred, pilots flip a switch which removes the metal cover. There would still of course be many issues, especially with temperature, but it seems like something that aviation really should have implemented in some regard at least a decade or so ago.

As someone who works within IT field (helping people with their own workstations and servers, specifically), I can tell anyone: most things people perceive as "random computer glitches" are more likely failures to read the error messages that have been given out by computer previously. And yes, people are much more willing to think "machine bad, human did nothing wrong" when faced with stressful situations. The right action at that point is to slow the work down and do a double-check on everything you consider to be "a glitch". In most cases, the fault will reveal itself.

Also from an IT background, never underestimate the vast quantity of nonsensical erroneous behavior that you'll find in Microsoft products if you work with them long enough.

[@josephdestaubin7426]

It's not the people blame the machine, it's rather that they blame the programmer of the machine. And yes, it's much easier to blame an absent human (the programer) than it is to blame the present human (the user). The name for this is "proximity bias." There is no known phenomenon that would describe a bias against machines other than in the movies. The closest you might have is "mechanophobia", which is a fear of machines, but surely you're not suggesting that. It's much more reasonable to conclude that when people are blaming the machine irrationally they are really just blaming the guy they don't know and who is not present: the programmer.

Also absolutely OP, if people would just take a breath, slow down and read what the computer is telling them I wouldn't have half the tickets I have. _"Hello, my computer is broken, I want to do [thing] but I get an error."_ > "Okay, what does the error say?" _"I don't know, I didn't understand it."_ >"Okay, can you read it to me?" _"No I clicked 'OK'."_ ... 😐😐 Takes every ounce of restraint to not just yell 'Why?!'. Why do you just click OK on an error message you don't understand?

How they don't realize that's just making things worse is beyond me.

[@Steve55D]

While stationed temporarily at Korean alert pad,, we had a serious incident during the takeoff of two F4C fighter aircraft. During takeoff climb, the wingman warned the lead pilot that he had fire from the underbelly of his aircraft and that pieces of debris were flying off the aircraft. Lead aircraft experienced an immediate fire warning light and had no choice but to eject from the aircraft safely. One piece of the debris from lead a/c actually struck the windscreen of the wingman's a/c and caused spiderweb cracks but no other damage. When I was provided the accident report, it indicated that the afterburner fuel line had been chafing against a electrical harness ,plug which caused the fuel line to chafe rendering a serious leak of the afterburner fuel line(36k lbs/hr) and serious sparking of the electrical harness. I submitted a recommended maintenance procedure to affix "spiral wrap" around the afterburner fuel lline which would prevent future chafing of the two components. Spiral wrap is comprised of a tuff plastic like material but pliable and easy to wrap around any type of liquid bearing line. The recommended fix was entered into the engine tech data manuals.

[@cedric3973]

I am sure it's a change you took the time to implement that saved many lives. Just saving one life is worth the effort.

[@captarmour]

over the years I have so many times asked "why are you transferring fuel?" "Why Is this tank lower?" "how do the right and left fuel flows compare?" Yes so many pilots see fuel lower in one tank and want to start transfer(crossfeed) without thought. In the business of safety we have to keep our thinking caps on!

[@joesterling4299]

What surprised me is that even after #2 engine flamed out, they didn't shut off the crossfeed valve. An engine doesn't fail because of an instrumentation computer glitch. It should have been obvious at that point what the reason for the imbalance was, and that the instruments were right all along. Maybe they just were too distracted with the emergency?

[@captarmour]

@@joesterling4299 one of the important things is to realize that any situation we are not familiar with slows down out thinking, in other words diminishes our brain power, to mitigate we go "back to basics"...Control, Power, Drag, for an engine to produce power it must have fuel, how much and where from...

[@captarmour]

@@ursodermatt8809 the procedures assume we have a bit of brain power...if fuel flow and power are close to equal on both engines, then the lower fuel level is probably because fuel is flowing somewhere else besides into the engine...I remember once on a Dash8 I'm recording the engine parameters in the logbook, normally done on first flight daily, and wondering why the Inter Turbine Temp(ITT) on one engine is so much higher than the other. then I'm wondering why is the airspeed so high. I pulled the power back to where the ITT on both engines were about the same and the airspeed came down to where it should have been, but the Torque on one was significantly lower than the other...problem, under reading Torque gage! I flipped back a few pages to see when the offending Torque got offended...was about 4 or 5 days earlier, that means over 8 captains(16 pilots) missed it!

Nice moment at 14:00 when Petter says: "....by opening the cross-feed valve..." Notice how he doesn't just reach up to the imaginary switch in the imaginary overhead control panel - his eyes flick up to confirm that he's operating the correct imaginary switch! That's proper training for you. :-)

For most of my life I've worked on various types of instrumentation. It's been my experience that many people seem to automatically blame the instruments if they see a puzzling indication. In this case, the pilots had two possibilities with the fuel indications and the usage of the crossfeed valve. 1. The fuel indications are correct. 2. The fuel indications are wrong. In either case, if the fuel indications don't equalize, the crossfeed valve should have been closed after a short time.

Top tip for all the hardware guys and general system users out there ... it usually *isn't* the software that's mysteriously gone wrong when a working system malfunctions. There *are* times that a design can be at fault and you will get initial problems that are corrected during commissioning but once a system is in and up then if a malfunction occurs it will save time to initially look at the hardware rather than try to 'teflon shoulder' the problem onto the SCADA design team :grins:.

He said " Altitude in our fuel; nobody will get me loose altitude now", and that is what saved his passengers. Nice work

[@jfmezei]

Some background from Canada: After incident, when pilots returned to Canada, they were welcomed as heros, big press conference in front of media etc. Pilots were clearn uncomfortable as they would have already known what they did wrong. The small Québec rural town where the captain was born even raised a statue of him. When the report from Portugal came out, the Transport Canada went a bit further and investigated Air Transat's training procedures. *Apparently* on an ETOPS flight, you must not cross feed from one side to the other in order to not jeoperdize your good side when the other side is malfunctioning. What was stated was that the 330 was capable of flying with fuel imbalance and that this si why the computer did not suggest actions. Transport Canada fined Air Transat $250,000 for the maintenance procedure violations and allowing plane to make 13 flights with the improper pump. And the Airline say its ETOPS reduced to 60 minutes for the 330 and 90 minutes for the 310 and the 757 they had until Air Transat demonstrated they had improved their ETOPS training. One aspect that bugs me: at regular intervals, the crew must check fuel available in each tank. They should have noticed that fuel "consumption" was much higher than normal before an imbalance warning came out. As experienced pilots, they should have a good "feel" for how fast the fuel drops during flight and should mentally detect when there is less fuel remaining than would be expected. This is expecially true once they activated the cross feed valve, they should have been monitoring the good tank and notice that it was dropping much faster than what 2 engines normally consume. I assumed this would be what would differentiate an expereinced from inexperienced pilot. Another thing I heard was that upon loss of an engine, and ETOPS flight is supposed to drop to 10,000 feet from an engine/aircraft performance point of view. Not sure if true (but make sense if lower speed required denser air, and more rudden authority to keep straight). In this case, It wasn't an issue, but had they completed the drop to 10k feet before second engine died, when it died, they would have had far less range to reach any airport.

[@MrMattumbo]

The way I see this accident is that while the captain messed up big time he was able to 'fix' it and get everyone on the ground safely. Not ideal, but still praiseworthy. The guy was a great pilot in the stick and rudder sense, just not good at managing new fangled computerized systems (really should be flying an Airbus though). I would hope these days pilots know better than to chalk stuff up to a computer glitch, but for an older guy in the early 2000s' that must've seemed probable and fed into his confirmation bias regarding the system. Still, I'd rather have a pilot that knows how to fly the actual plane than a pilot who's mastered the automation, we've seen plenty of preventable accidents caused by overreliance on automation and they ended in a loss of life instead of just the loss of an airframe.

[@Torbjorn.Lindgren]

Dropping down due to loosing an engine is usually the last thing you want, altitude is both potential energy and gives better fuel efficiency! and you thus want as much as possible when things start to fail, ESPECIALLY on an ETOPS flight, so I really doubt that descending to 10k feet would be part of any engine-out ETOPS procedures. As various real pilots (I'm not one) have discussed many times the normal reaction on a loosing an engine on a twin engine aircraft is a controlled drift-down to the one engine altitude, basically keeping the correct speed by slowly reducing altitude to provide the now missing engine power, which AFAIK is what these pilots did when they lost the first engine. This preserves as much potential energy as long as possible and gives the best possible fuel use - all leading to having more time. In this case the second engine failed a little while later at which point the drift-down gets much steeper since it now have to convert altitude to energy to replace both engines power to keep speed under control (and air will start to leak out). The pilot could have dived to 10k to avoid the air pressure falling too low and triggering the oxygen masks but didn't. I believe no pilot would do that in his situation - he's over water when the second engine fails the *only* potential power he has left is his altitude, you don't throw that away until you're very close to the airport, if necessary circling there to burn of any excess height. Note that with one engine not working the plane will need more fuel to cover a given distance even at the same altitude and once you start to the drift down to a sustainable altitude it'll get (slightly) worse. I would expect that on an ETOPS flight loosing one engine will automatically trigger the "is there any airport we can glide to if necessary, and if not where is the closest and how can we make it into gliding range if something more happens" thinking. Which is a exactly what they did here. If I remember correctly the Mayday episode on this flight claimed that their normal flight plan wouldn't have left them within gliding range of that airport but due to the winds that day they were flying further south than normal which made this landing possible. It also mentioned that something about the Airbus fuel management system made it less obvious that there was a leak and that Airbus did changes to that after this accident. Regulation doesn't account for pilots using the cross-feed valve with a fuel leak because if you include that possibility no flight beyond gliding range would be permitted by any airplane regardless of number of engines 😃

[@randomgeocacher]

Jean-Francois Mezei 21:17 yea, they descend to single engine service level (to avoid stall or something I guess). So you descend as per airplane specifications if you loose an engine.

[@carlosladen]

Hi, I live in Açores. It seems that the Captain was ready to ditch the plane, but thr ATC controller noticed that landing at Terceira was possible.

[@CMDRSweeper]

@@Torbjorn.Lindgren On a single engine, you can either do a controlled drift down... Or you can stay up and come down by force as in a stall. Those are your two options when 1 engine fail, and you do not save your speed or gain distance if you insist on holding your altitude until it stalls.

Also, I love when the dogs are hanging out on the couch with you without a care in the world. Adorable! ❤❤

[@derekt4017]

Great explanation of this astonishing event. When Captain Piché informed the Flight Director to prepare the cabin for a ditching, he told her that they had 10 minutes of fuel remaining and they were at least 20 minutes away from the nearest island with an airport -- Terceira. She immediately informed the cabin crew of the situation and they rather quickly picked up the remaining meal trays from the passengers and prepared the cabin for the emergency landing. The cabin crew did this all the while knowing in the back of their minds that they would likely have to land on the ocean surface--otherwise known as a ditching. The safety cards inform passengers how to put on the life vest and you can look at the pictures of passengers getting out of a floating aircraft and gently slipping into an awaiting raft. In the unlikely event that you should end up in the water, the life vest will keep you afloat or aid you to swim to the nearest raft. What the safety cards don't mention of course, but what every crewmember knew full well, was that the chances of keeping a jumbo jet intact after making contact with the water is quite low. In fact every aircrew member knows that surviving a ditching is highly unlikely. So as the cabin crew picked up the trays and secured the meal carts into position in the galleys, and as they described to the passengers how to put on their life vests, each of them knew in their hearts that a ditching most certainly would be catastrophic and not survivable. Mentour Pilot mentioned that the crew had one Portuguese speaking flight attendant who was helping the passengers who did not speak English or French, but in reality most of the cabin crew, including the flight director were fluent in Portuguese, and so they all helped passengers English, French and Portuguese. The emergency landing procedures included the shouts and commands which the cabin crew yells out in unison in English and French so that the passengers can adopt the brace position just before landing. Those shouts and commands would not have been executed in Portuguese because Air Transat and Canadian aviation generally requires that part of the procedure be done in English and French. It must have been truly terrifying but how satisfying it must have been in a jumbo glider to have made that bouncing contact with a runway, and not the murky abyss of the Atlantic Ocean.

Well explained, even the passengers didn't understand for most that the captain, yes didn't figure out the issue, but it was mainly a training issue. One passenger said: "do I think he is a hero, no, do I think he is a hell of a pilot, yes!" (hero as in Sully). A lot of them blamed the captain for the issue in the first place, the emphasis was never put on a fuel leak with no indication, at night, so very hard to see (almost impossible apparently). And the CRM was "good" but they didn't have the knowledge, didn't see any leak, didn't learn it in training, so they though of something and it kept getting confim by the warning (let say their hypothetesis was confirmed by the signs, but they didn't consider much the other hypothesis - but to be FAIR, they consider a leak, but it wasn't visible...). So in all fairness, I would feel safe with him as a captain, if I was a passenger. (at the very least, even if you consider, he is at fault (and the FO AND the maintenance guy.... no one thought of it BTW), he save everyone without anyone going through a crash landing - more than a lot of pilots that have encountered mind boggling situation can say).

[@thebiffer100]

I flew the A330/340 for years and all transatlantic or pacific crossings a fuel calculation is done at every position report ( 10 degrees ) AND transmitted back to company via ACARS. Two things are always examined. First is your FOB and actual burn. Second is the comparison based on the flight plan ( avpac ) for any gross errors that would potentially identify an abnormal fuel burn. This was a company requirement for this very reason to discover if there is a fuel leak. I am well retired now but let us just say that I did not fly for Air Transat. Not saying the results would have turned out differently but perhaps the issue would have been discovered much earlier. Great explanation and thank you as always.

About 10 seconds before touch down the Pilot calls over the cabin speakers. "Hold on to your seat belts, this is going to be rough." BAM!!!! The landing gear bottomed out. Turns out they were having very high winds with strong down gusts. If you've never been Lajes all you see from a passenger window on approach is Water, Water, Water, CLIFF, Runway. That Cliff before RWY 15 has a bad habit of causing Rotor at the Threashold. Enough rotor to slam an aircraft into the deck making for some very rough landings unless you go long. Also a C-5 needs a lot of runway and coming short at Lajes(only 10800ft of usable runway) is normal for them I found out. Anyway, we ended up on the ground there 2 hours longer than we were supposed to be while they performed an in-depth inspection of the gear.

He totally screwed up the approach, bounced the landing, over braked, destroyed the gear and for the cherry on top, ordered an emergency evacuation of an aircraft that didn't have a drop of fuel on board and which couldn't burn.

For years he worked for Québecair, flying into the Inuit communities and mining towns up north. He was known as the bad boy bush pilot...for years he smuggled marijuana into the USA from Jamacia until he was caught in 1983 at a small Georgian airfield with a full load of pot fresh from the Caribbean. He served 16 months in the local state jail...

I certainly hope that newer planes have better leak detection system(s) incorporated into them and audio/viisual display of such fault into cockpit. As usual your uploads are absolutely fantastic.

Thank you for another great video. All the best from Sydney Australia 🇦🇺 I once knew a ww2 fighter pilot whose engine got shot up over France and he glided about seventy miles back to England. He was at about twenty thousand feet when it happened, I can’t remember whether it was a Hurricane or a Spitfire. After the war he became a Viscount pilot for NAC in New Zealand and retired when 737’s were introduced. He also became a gliding instructor! Just a bit of a story from long ago.

Just discovered and have been devouring the videos in your accident & incidents playlist. I find them very informative, genuinely touching and sympathetically presented. I have one nit-pick in this video that may have been picked up by some other pedant - so apologies for any repetition. The Rolls-Royce engines fitted to the Airbus A330 were not RB211-535 engines as shown at 2:40. The -535 engines were exclusively used on the Boeing 757 family. The A330 used the Trent 700 family of engines. They share the RB211's triple shaft, 3 spool design heritage but were a much more modern derivative having a significant increase in bypass ratio from a bigger fan, higher thrust and lower fuel consumption. The Trent engine family was designed to meet the new wide-bodied twin engined aircraft introduced in the '90s such as the A330 (Trent 700) and B777 (Trent 800). Again, sorry for any repetition or if I've put... anyone... to.... 🥱... 😴

When I was in the Air Force, it was standard procedure to check the fuel quantities against expected fuel burn and to cross check fuel balances. A simple thing to do, lost in automation. Of course the aircraft that I flew on had multiple tanks and distribution all over the airplane, but I'm surprised that this isn't routinely done on other aircraft.

[@beverlychmelik5504]

@@roriquevernonii8439 I'm very sure with KC10 as well. Still, if I have for an example, 2 engines that use 2500 Lbs per hour in cruise per engine and after 2 hours I have used 15k LBS of fuel, where did the extra 5K go? That's just from the totalizer and fuel flow. One can go further in one's investigation. My airplane kept coming back with fuel imbalances, but that was because I had 2 very healthy pumps in one of the outboard mains, and less robust in some of the others so that tank overrode the other tanks when in cross feed. That took us a couple of days to straighten out and I burned about 20k of fuel just troubleshooting, checking and playing musical fuel pumps.

[@alexkimlon5851]

I am not too sure which operator you are referring to, but it is stated in the ANO that a fuel check is required to be done at least every 1 hour. It is standard procedure on all airlines to check your fuel at every way point. I used to fly before the days of CPDLC, we used to report fuel figures, wind, temperature and etc at every MET reporting position on the airways chart. It is stated on the Jeppsen manual, these information are required to be transmitted.

[@raheesom]

I've flown commercially a lot in my life, never experienced any emergencies. These videos explaining how maintenence CAN sometimes be cutting corners, and in fact too many times human error can overlook critical problems... Gives me more anxiety re flying.

[@bobbywelch6035]

Belongings can be replaced, human life cannot. One pilot told me, any landing you can walk away from, is a good landing. Very glad to hear everyone lived to tell a tale that most people don't live to tell.

[@mandolinic]

Any landing you can walk away from is a good landing. But if you can reuse the plane afterwards, that's a bonus!

[@A.Lifecraft]

Its so weird they don't have a warning for scenarios where the decrease of fuel in the tanks doesn't match the engine power settings. Because anything that makes you use up the fuel prematurely is inherently dangerous to aviation. There should be a tiny red light somewhere that says "check engine health immediately, you consume fuel as if you where going on 300% power"...

[@chrisbowpiloto]

Lifecraft I am really curious why they didn't notice that. Light or no light, that fuel burn should metaphorically slap you in the face

[@vask92]

Yeah any plane should have a fuel burn indicator. Any car has it, how come planes don’t?

[@wesleyhurd3574]

@@vask92 In a typical modern car, the fuel economy gage displays the amount of fuel that the computer has commanded the fuel injectors to allow into the engine. It is a calculation based on time and expected fuel delivery. If the engine has an external fuel leak, the computer has no way to quantify this. However, it may trigger the MIL (check engine light) with a low fuel pressure code. On the other hand, you would be right to expect a multimillion dollar aircraft to have more sophisticated sensors than a car.

[@plcwboy]

@@wesleyhurd3574 a modern car calculates fuel use as you state, but it also has a gauge which indicates quantity of fuel in the tank. It should be a very short line of code to rationalize the fuel flow rate against the rate of decrease in the level of the fuel tank.

[@wesleyhurd3574]

@@plcwboy Automotive fuel gauges show an approximation of the amount of fuel in the tank. They can easily be off by 10-20%. You would end up dealing with a lot of false alarms. I'm sure it would be hypothetically possible to put a fuel burn vs quantity monitor in a car. But it probably would be more trouble than it is worth to make it useful for a vehicle that never leaves solid ground. It would be much easier to justify something like this on an airplane though.

[@martinpattison1567]

I have watched many videos of plane crashes, not only on your channel but also on others. The one thing, I see regularly is the need for someone to go from the cockpit and check the wings for a problem on either side. Looking for a fuel leak, engine fire or damage to either wing. In one video I watched there was a camera fitted in the tail of the aircraft and it was connected to the cabin entertainment systems so passengers could see the front of the Aircraft and where they were headed. Would it not be a great idea for aircraft manufacturers to also fit a camera in the tail of the Aircraft showing an image of the wings on a screen in the cockpit? Martin. (Thailand)

[@DJI-mini3]

hi.. I love your videos, it's refreshing to have a qualified pilot talk you through these events but without too much technical jargon. After I watched this video I was left with an unanswered question. please, if ive missed something simple here then let me know... If the pilots suspected that indeed, there was a fuel leak , then why leave the crossover valve 'open' why didn't they transfer a given amount of fuel to the 'low' fuel tank, then shut the crossover valve off and then monitor that tank for a leak, rather then lose all the fuel remaining. If the fuel that had been transferred held (no leak)then they could explore other reasons why they were using so much fuel. To me, that would have been a patently obvious thing to do. I would love to hear your thoughts on this ?

[@AJ-qv9yo]

Great video and explanation. Thank you. However, how could the flight crew have missed that the fuel was getting critically low _long_ into the flight and long before it was a problem? You seemed to have missed this in your otherwise very instructive explanations. The pilots even balanced a huge(?) imbalance in the fuel tanks. "Using" 12-15 extra tons per hour isn't peanuts. Aren't there instruments to show consumption and the total amount of fuel left, and possibly more indicators regarding the fuel status? And if these parameters don't fit the expectation and are exceptionally low, a leak is very possibly even to a layman. A computer/sensor glitch on all of these fuel parameters must be regarded as highly unlikely, confirmation bias or not. In addition, the other unusual indications, oil temperature and pressure showed that there was something quite wrong with the aircraft. A flame-out because they were running on fumes is a little late as a low fuel indicator. Therefore, I wouldn't praise the flight crew as much as you did, except for the safe landing, of course. But then, I am only an armchair enthusiast when it comes to aviation.

[@marhawkman303]

Well, I think Petter's thought here is that it's a problem seen so rarely that people don't focus on it in training. Especially a major leak of jet fuel in the engine where the fuel DIDN'T burn off. That's a lot of fuel to NOT go up in smoke right next to a turbine spitting out thousands of degrees of heat. But, it didn't burn. and got scattered in the wind instead. Jet Fuel A is not a dark cloud in cases like this. It's near invisible as a mist.

Do airbuses often glitch? The AF447 pilot also thought about a computer glitch, that's not the first thing I would think about when faced with a redundant computer system that ensures the safety of hundreds of passengers. The fact that they immediately discarded the error messages as a glitch doesn't make sense to me, unless of course the planes have minor glitches every now and then
