Tried to checkout the current sponsor. And it hit quite close to home. But EUR40 shipping to EU? Sorry, thats a deal breaker.
Good product, good sponsor. I really like mine and I always feel better when UA-camrs have high quality sponsors.
@@toughiq Almost doubles the price of product :/
I flew in Europe a few weeks after this incident and I noticed that the vast majority had their belt on for the whole flight , in my previous experiences, there’s always been a unanimous sound of buckles being undone as soon as the sign goes off, but not on this flight. Did definitely notice a change in culture
Give it a few months and the usual stupidity will have returned.
It's already back to way it was... I still fail to fathom why are people doing that. Are others built so differently to me that they find that tiny belt so constrictive that they absolutely have to unfasten it given the first possible chance?! Most of the time, I can barely even notice its on... I have a habit of fastening it whenever I sit down but once there was a commotion in the cabin and I got distracted, then I spent almost a minute fishing for it only to figure out I've already fastened it and I didn't even register or notice it...
I used to be the kind of person who immediately undoes the seatbelt, but in the past years I’ve heard of so many incidents that I now always keep it fastened when I’m seated. It’s just not worth the risk.
Seat belts do not have free will. Experts are ubiquitous on this.
@@amarissimus29 What?
I always keep the seatbelt on especially when I'm sleepy. I don't want to wake up by my head smashing into the cieling.
I have had that experience aboard a sailboat, when it got turned beam-on to the swells during an overnight cruise - gotta say, there are definitely much more pleasant ways to wake up, though few more effective ones.
Very wise! Join the club!
So if it is especially when you're sleepy it's not always because it's one of these things you can't partially do, you're either buckled up or not.
Wait, people can actually sleep on a plane? I wish.
@@kasperpedersen3420 You're talking gobbledegook! 🤪🤪🤪🤪🤪
Back in 1995, my wife and I went to Hong Kong on a company sponsored award program. On the way back home we flew Singapore Airlines from Hong Kong to Hawaii, a 14 hour trip. On that trip at about 1am in the morning we experienced sudden extreme turbulence without any warning. Some people were laying across several seats and others although seated did not have seat belts on. Suddenly the plane dropped violently about 3000 feet as if hit by a huge fly swatter, and anyone and anything not belted down hit the ceiling or overhead luggage compartments. Even several heavy beverage carts slammed into the ceiling and crashed back down. Fortunately my wife and I were belted in our seats so we watched as everything slammed into the ceiling. It was terrifying and many people were injured. Apparently as we learned later we had flown into a Typhoon. We landed safely in Hawaii hours later and were still shaken by the experience to the point my wife did not want to fly the next leg from Hawaii to San Francisco. She wanted to take a ship but when she learned it was 6000 miles and would take a week she grudgingly got back on the airplane. We will never forget those terrifying seconds of violent turbulence.
I use the adjacent seats receptacle when I’m lucky enough to be in an empty row.
Why did the pilots fly into a typhoon? They look at weather reports before the flight, and they can see it on the plane's radar.
it would nothave been 3k feet
Yeah I was on that flight too so scary I saw Buddha outside the window I thought I was about to die, cool story bro
@@phillcom3 it was actually 30k feet, happy?
I’ve been 100% on board with seat belts all the time since learning of the Aloha Airlines airline where a huge section of fuselage disappeared. The seat belts kept those people from flying away. Only casualty was an unfortunate, veteran flight attendant who was in the aisle.
I always keep my seatbelt on, especially since I like to sleep on planes, and would need to be awake to hear any fasten seat belt warnings.
Same. Even on a 12 hour flight.
And make sure the seatbelt is done up over a blanket if you’re using one. I was just on a Virgin flight coming back to the US and the flight crew were really enforcing that. They were actually moving people’s blankets to see if the seatbelt was fastened underneath.
@@jeremypearson6852 They have to check when the seat belt light goes on poor things. I had my handbag on my lap when I fell asleep reading and was asked to move it so they could see. Not their fault. I always wear a jacket on a flight so I don't need a blanket. My old denim jacket is old enough to be soft and warm, I can wear a jumper under it, and it has several inner and outer pockets. I can keep my phone with charger in one, my kindle in another, and my passport with my kindle, but I had some currency left in my handbag for a tea! I would recommend a similar jacket. I don't use my handbag except to keep a toothbrush and makeup to freshen up and I zip the handbag into my carry on. Less rubbish to cart about and more comfortable. If you have glasses you can keep those in an inner pocket as well.
Also, in the absolutely rare case of an emergency landing where you had to leave everything behind, not only are you warm, you have your most necessary stuff with you. Comfy old denim jacket for the win!
The point is CAT cannot be reliably predicted, so it shouldn't really matter on whether you are awake for the fasten seat belt warning or not.
Same, even on short flights. That seat belt only gets unfastened, when I have to go to the toilet and when it's time to debark (which I often do as one of the last, since I don't like standing between people who like to rush out).
I appreciate the "why can't the pilots just telle before we hit turbulence". I recently had a pax complain that she only experiences turbulence when flying our specifc airline and we need to be better trained to stop making turbulence. Yes, making.
Stop making turbulence!!
That’s unacceptable.
What’s your airline? So we could avoid it.
Damn people really do think you control the airspace around the plane 😂
Keep your seatbelt on, even loosley - you can always cinch it up quickly if you suddenly "feel light". Much quicker to cinch it than to plug it in.
Your graphics team is going from strength to strength. This episode was particularly strong from this point of view. My congratulations to your team🙏😀
I have been aware of Clear Air Turbulence from a very early age. Back in the sixties my parents subscribed to a children's general knowledge magazine called 'Finding Out', and one article featured a giant, smiling cartoon CAT waving its paw and sending a hapless jet onto a rollercoaster ride! Being a cat lover I've always remembered this idea of using the acronym for Clear Air Turbulence to spell out my favourite pet animal!
This comment about a cartoon got 18 likes why my owesome funny about "you may die but there are good news😅" got 1. Some need a bit of turbulence.
Honestly that’s such a good way to teach people about Clear Air Turbulence! I’m glad you were able to learn about that back then.
A razor advert in a turbulence video - imagine trying to shave on a shaky flight… 😂
I feel like that was a gag in one of the Airplane movies.
I have some very old razor blades that are called "Happiness Brand Razor Blades"......which seems like some very, very dark humour!
@@jimmym3352 Indeed it was
It would look like the bathroom-sink scene in "Poltergeist".
I was watching the video about the Viking cruise ship that lost power in a severe storm and was in danger if running aground and breaking up. During the part were helicopters were lifting the passengers off in the force 7 storm, a Viking cruise advert came up.
The sudden cut from waver breaking over the decks and furniture in the restaurant flying everywhere, to passengers sunning themselves on the deck and enjoying a gourmet meal was so funny.
Depending on conditions, mountain wave turbulence can also be experienced a LONG way from the mountains that cause it. An example from my experience flying small aircraft: I was flying from Phoenix to the LA area in my Cessna at night on an IFR clearance. I started picking up the noticeable repeated updraft/downdraft cycle of mountain wave turbulence about over the Gila Bend VOR - almost 250 miles from the San Jacinto Mountains (the mountains near Palm Springs, CA). Since I was IFR (a good idea over the dark desert at night), I couldn't request lower, and performance of my aircraft kept me from flying too much higher to avoid it vertically. The turbulence increased as I got closer to those mountains, and then went completely away as I went through Banning Pass into the LA Basin. Aside: 250 miles of such turbulence in the dark over the desert is no fun in a single engine Cessna! Imagine riding a roller coaster for 250 miles!
15:13 & 16:06 Thank you for sharing the clips from my channel Petter! I have been a massive fan of yours and have watched every video you have posted!
I am a new aeronautic engineer in the Commercial Airline Industry & can not communicate how much of a resource your channel is for general industry news & information & your specific drilling down into crucial engineering issues. Your channel is my fallback for all aeronautic industry updates & cutting-edge news. Thank you.
I cannot now unsee "CAT turbulance" as an invisible cat swatting at aircraft, because cats are gonna cat.
100% 😆
Ok…..
ATM machine
Real Housewives on one side of the meme, a white cat causing turbulence on the other, with a plane in between.
There is a 'claws' in airline ticket contract that excludes CAT turbulence.
I remember a airline pilot friend of mine told me they avoided lenticular clouds... that was 45 years ago.
I always keep my seatbelt fastened. But I want my neighbor to also. I don't want them crashing down on me. Make it mandatory!!
Been flying as a passenger since about 1960. A lot was 'Unaccompanied Minor', in those far off days, I was chucked on the jump seat to be out of the cabin crews way. Knew my way around a DC3 cockpit before I knew the controls of car. Was ALWAYS seat belt on! Have done every time I fly.
Always a great day when Mentour uploads something new on a new topic!
Glad you enjoy it!
Yes, details are important - but a simplistic physics view is that if more energy is present in a “fluid system” (atmosphere), the exchange and dissipation of this energy (heat differential) will create more movement. Add more humidity (same heat, vapour) from “neighbouring system”, sea and land. And then all these complex interactions are still a bit beyond us…
As you allude to, an imminent solution must be technical (like LiDAR). Long term… well, that’s a real struggle already. 😅
I kept mine on coming back from Bangkok this Feb. We hit a bad area over the Middle East. Enough for the flight attendant to hit the ceiling. The turbulence was enough to lift people in their seats. Was an awesome experience. Everyone was making concerned moans and whimpering which would naturally make any seasoned flyer slightly sweaty. My 2 year old daughter got me through it. She was giggling the while way through 😂
Bonus roller-coaster ride, what's there not to giggle about? 😉
Oh, great, I was a bit bummed that there were no new uploads during the weekend, but now all is good.
Good to hear! We are switching to weekday uploads from this week.
New Mentour Pilot video on Thursday!
@@MentourNow thanks, always looking forward to new videos.
And yeah, as someone who manages a fairly big UA-cam channel - Sunday is definitely not the best day to post, so moving to weekdays is a reasonable decision.
Wait wait wait. We watch for quality and not quantity. Of course this is a bit of a joke on my part. I am very confident that Mentour followers are great folk. I love the comments.
I usually watch videos on weekends but I can just see them later.
Why is CAT not mentioned in the safety briefing? Never understood that. People are much more likely to keep their seat belt fastened when they know what the true risks are.
One of those cases where marketing and safety are at odds. However I recall unexpected turbulence mentioned the last time I flew Singapore.
I find it very annoying when people next to me instantly unbuckle their belts when the seatbelt light turns off, and when the plane just touches down.
My problem with people not wearing their seatbelts is not because they might get hurt, that's on them for being too stupid to keep the belt on. My problem is that their thoughtlessness will hurt OTHERS who weren't so callous. I'm sure it's not intentional, but stupid causes more evil crap in this world than intentional acts. People need to THINK.
But no, they're too busy playing with an i-whatever, listening to tunes, or just so far up their own butts that they cannot even conceive of how their actions could effect others.
I have a friend who, way back in highschool, when I was driving would unbuckle his seatbelt as I pulled into our destination. I scolded him multiple times not to do this, but he kept on doing it. That is until I started standing on the brakes when I heard his belt unbuckle and he face planted into the windshield. Only took a couple times and he knocked it off.
Moral of the story, some people only learn the hard way.
I agree with you that people should not take their seatbelts off as soon as the plane lands however if the seat belt light turns off then its perfectly fine, pilots don’t turn the light off unless its safe to do so.
@@minhajsyed9874Why do you comment this on a video where a literal pilot (and instructor) tells you to keep wearing your seatbelt unless necessary, right at the beginning of the video? If you want to stretch your legs or go to the toilet you're allowed, but there's a risk. When you sit down it's simple to keep it on (loosely if you want) to drastically reduce the risk of injury on an unforeseen turbulence event.
@@minhajsyed9874Just last evening another 30 passengers got injured on an Air Europe flight because of severe turbulence the second after the seatbelt sign was turned on.
There's probably substantial overlap between the groups of people who don't wear seatbelts on plane rides and who put their feet up on the dashboard (you know, where the airbag deploys from) for long car rides.
Hi @MentourNow
your current sponsor hit quite close to home.
But nearly 40EUR to ship to Europe?
Sorry...but thats a no deal. Its more than half the price of the product, even without the "now" deal.
I am quite confused.
For me a well fastened seat belt isn't just a precautionary measure against unforeseen forces. I find it actually helps my posture in the seat and increases my comfort. Over all a win-win for me, but body shapes and and feelings towards being even lightly restrained do vary.
Funny how "back in the day" people used to hang out at the bar on the second floor of a 747. I grew up a TWA kid (The cockpit in an L-1011 was lit, literally) and flew often due to my term pass (I could book any TWA flight for free or fly most any other airline for $10-20) and I only remember one instance of turbulence coming into St Louis. I'm just wondering if turbulence is actually worse now or is it just we all have ways to document the incidents so these events get more coverage than before. Thanks for another great episode Petter!
There are 2.5 times as many passengers traveling by air in 2019 compared to 2000, and 5 times as many compared to 1980. We really should be getting 5 times the number of turbulence incidents.
That’s a good question, but I’m guessing that with news stations absolutely everywhere trying to get “ the story “
As well as social media, we are hearing about these kinds of events much more often.
I remember flying to and from Hawaii on a 747 in 1977 and during both flights my parents sat around in the upstairs bar, no seatbelts anywhere and no one even spilled a drink.
Greatly increased air traffic with increased recording and communications creates a false impression of increased incidence and severity. Bags were more often checked and stowed and personal items brought in to the cabin were not weighted bricks (electronic devices). Seating was farther apart, less crowded, and more cushioned meaning you were not smacking the seat in front of you on the smallest of bumps.
I can imagine that modern latches for overhead bins may be weaker as the aircraft shave weight from every conceivable point, but that may not be the case.
I'm fron flying in the 70s too. What I want to know is how Led Zeppelin could play piano...drink and party etc on their 707 and nothing happened to them!! 😊 I love Zeppelin by the way...thank God nothing happened to them!
1968 a flight on a DC-6 4 engine prop. Flight from West Yellowstone to Salt Lake City. Thunderheads to 50,000 feet all around,, like flying through a giant's mushroom field,, 10 to 20 miles between each column of cloud. The clear air turbulence between was stunning. a one hour flight that you were EITHER plastered into your seat by 1 to 3 Gs or hanging from your seat belt by the negative -1 to -3 Gs I thought it was kind of fun. Puke on the ceiling, puke on the floor. Interesting,, my stomach rebelled finally after we landed. Walked down the stairs to the concrete and my stomach instantly required a run to the nearest toilet. There is no modern roller coaster that has ever been exciting since. The real thing was enough.
I flew on SQ319 2 days before this incident on an A380. it was the first flight for my 1 year old and whilst it was frustrating that she had to be waken up from her bassinet as we tracked over the bay of bengal over Myanmar, 20 minutes later, we understood why. For it to be choppy on an A380 through equitorial or inter-tropical convergence zone is saying something. I've done that segment countlessly on SQ over the past 30 years and I can emperically note that it's getting a lot worse. Sadly, the chap that passed away on SQ321 lived opposite the river to me in Gloucestershire and was on a RTW tour. It's just one of those acceptable risks we anticiapte when flying
Our child didn't want the basket also 1 year at that time also a380.
I always keep my seat belt on for the entire flight, unless I have to use the restroom. Other than that, I don't see any reason to take it off.
Good, but on long flights you should stretch your legs from time to time.
@@MentourNowI don't have health problems, am not elderly, but I wear compression socks, up to my knees, on long flights. Might be overkill, but along with strolling around occasionally down the aisle, so far so good. But, otherwise my seatbelt is on all the time. Why not?
Absolutely right
@@MentourNowI get up to the bathroom every hour or two...older with a crappy bladder...seems the pressurization does it to me!
Today, July 1, air europa flight madrid-montevideo was hit by severe turbulence and had to divert to Natal, in Brazil.
According to bbc:
"Airport officials said some passengers needed medical assistance and were taken to the nearest hospital.
A local medical team told Brazilian media they attended to at least 30 passengers of various nationalities and that 10 of them were taken to hospital.
The patients had hit their heads during the turbulence and suffered injuries including cranial fractures and cuts to the face, the team added."
Oh wow...that is crazy! Not wearing belts right after that other disaster?
@@juliemanarin4127 again it was quick, only a matter of seconds between warning from crew to turbulence hit
To add that one passenger got stuck in the ceiling
@@juliemanarin4127 the really crazy thing is that the industry keeps turning off the seatbelt sign. Most comments seem to be mad at dumb passengers unbuckling, but tbf they simply think the airline told them that it is now safe to unbuckle.
And no one, not even Petter, wonders why they have the sign, or why they ever turn it off. It would be so simple, and so cheap to replace the sign with a more appropriate sign like "now you are allowed to go to the toilet" or something.
Reading reports, it was violent enough that a few people (including a 2 year old) busted through the ceiling panels in the cabin and were stuck up there after it was all over.
My dad was a radio operator on B-50s in England at the beginning of our nuclear alert and readiness days. Some missions were extended (over night) as the USAF had planes in the air constantly beside those that were ready for scrambling.
The relief crew was flying and dad was racked out. He said he woke up floating and then slammed into the rack. he got to his feet and then began floating again for a couple of seconds before slamming into the deck. He got his "stuff" sorted and strapped on a chute. He said that if it had so much as twitched he'd have "popped the cork" and jumped. Turns out that they had hit some clear air turbulence over the Atlantic followed by two massive down drafts that dropped them 10,000 and 8,000 respectively. 😳
Me personally, I like to keep my seatbelt on at all times and urge others to do so too
I just took my DGCA Meteorology exam some days ago, and I already knew about these types of clouds. But after studying and understanding these kinds of incidents, it really makes sense.
Thank you so much for making such quality content.
I keep the seatbelt moderately firmly fastened whenever I'm sitting down, which is most of the flight. I happened to be walking back from the toilet during a moderate negative G event and my normal walk launched me off the floor for several steps which was a LOT of fun, but I was very aware that I was lucky and got back to my seat quickly and put the seatbelt on quite firmly indeed.
It would be great to see a video on the hail damage suffered by the Airbus A320 of Austrian Airlines flight OS434 on Sunday 9 June 2024. It’s amazing the pilots managed to land safely!
I didnt hear about that!
Waiting for the report on an unstabilised approach and rapid unexpected descent at low altitude on arrival to Stansted in Dec 2023 that the AAIB is currently investigating. But that might be a little close to home for this channel.
Won’t cover it. It’s an Airbus incident.
@@thereissomecoolstuff It was much in the public news, at least in Austria itself and also in Germany.
@@NicolaW72 didn’t make it over here. Juan Brown a United 777 pilot didn’t review it here. He’s our goto for aviation mishaps.
Years ago, my family was on a flight between the UK and Cyprus.
They hit turbulence and the plane turned on its side and nose dived about 5,000 feet. The pilot managed to recover, then it turned on its side and nose dived again.
The pilot was interviewed and mentioned that he knew there was so many thousand feet left and that he managed to gain control before they went through that critical point
Another time I was on a flight, we were flying through severe turbulence and was told we were going through 150mph crosswords.
This was really well-explained and well-presented. The fact that an aircraft the size of a 777 could go through that rough of turbulence is quite interesting
That's misconception, may be the reason people fail to follow the "always keep your seatbelt fastened" recommendation. Any turbulence, strong enough to cause serious harm, is likely to be big enough (area wise), so that aircraft size doesn't matter. (wake t. is a exemption to the rule). It may be different within a CB, but those show up on weather radar and are avoided.
Why would you say that? That would be like saying the plane the size of an A-380 would have an even harder time dealing with turbulence.
It's really the smaller planes that get bounced more by turbulence, POSSIBLY. The design of the plane is going to determine how it deals with turbulence.
The 777-ER is used on some of the worst routes for turbulence in the world BTW, one being between the west coast of the US and the east coast of Asia when the route goes up to the Arctic Circle. You can have 5 - 8 hours of being bounced. I remember one flight where there were a few bad bounces and it was rough, like almost continual bouncing for about a hour, while the rest of the time you maybe got bounced a couple times a minute.
Could you imagine if it had been a smaller aircraft?
@@johndoh5182That sounds really fun tbh
@@eliteiel9747 I hate that flight, but I have to make it every 2 - 3 years. It's also long.
One thing I NEVER worry about though is the plane because a 777-ER is really a smooth plane and considering it's about the only plane I see making that route I assume all the airlines trust that plane on a rough route. It still sucks though when you hit those rough patches that go on and on and on for hours.
I always use seat belt during the whole flight. Overall experience of the flight for me is better. It is like in car, you have to wear seat belt for whole time you drive and you take it off when you stop to stretch your legs.
another great video, they just keep getting better! Appreciate the work you and your team do 🤩
Our pleasure!
To be honest, this is my biggest possible fear, I even avoid super fast lifts for the same reason, and yes, I didn't want to climb OTC in NY for this reason, I could even faint so I don't know what this would do to me, the closest I experienced this was departing from El Calafate (FTE) in late April 2024, it was mostly fine while the B737 was climbing until out of the sudden it started sliding to both sides, and then jump up and down like a cork in jumpy waters, the whole thing lasted seconds but it was enough to got me s... scared.
I have to fly often to Buenos Aires, I live in the Netherlands, and every time we are close to the equator I begin internally praying we will skip any sudden turbulence (English does not make any difference, we call these "pozos de aire", air holes basically for you fall into them), so far I've been lucky and I hope to remain so.
Always keep your seatbelt on, and most importantly, do the same to your children, the last 2 flights who ran into this described children flying into the air.
This accident can happens to any flights. My condolences to the British passenger.
It was the 11th time I had ever been on an airplane. It was a short flight. And our plane “dropped” twice. Think Tower of Terror drop. I’ve been on 137 flights since then and have never experienced anything like that again. The overhead bins popped open- spilling luggage onto people. I was in a window seat and happened to be next to two college linebackers and they protected me from the luggage. I covered my head anyways because smaller random objects were flying around. I had to get off that plane and get on another plane. I was shaking. I’ve never not worn my seatbelt on a plane since, and try to keep my restroom visits to a minimum.
This is such great content! My undergrad degree was in physics, so I love your gift for presenting concepts (here, wing-tip vortices) clearly and without dumbing-down. Links to deeper dives and citation of information sources is fun for us nerds out there. It also means that your videos are trustworthy and very responsible.
Remember this, when you are sleeping, always fasten your seatbelt, you don't know when you will wake up smashing your head against the ceiling or being tossed around.
Not only when you sleep, ALWAYS!!
Even when you're not sleeping... Sudden vertical accel. can happen without any prior notice, and you will NOT be able to hold on through the strength of your sheer will no matter how strong you think you are or how good are your reflexes.
@@zwerko Oh ok, even if you have your seatbelt on?
Please let me know if I am over simplifying this but isn't there a very logic and simple solution to this problem? Historically speaking aircraft were not able fly over many kind of weather clouds like the much loved DC-3. this is now changing with the modern airliners that can fly at a height of let's say 12 km. Isn't there any possibility for the manufacturers to optimise future designs to accommodate for example better suited wings and so on for higher operating altitudes? (please let me know if I'm wrong)
I always keep my belt on during whole flying time. I have always seen that seat belt on sign mid flight is always ignored by passengers. They don’t even seem to have heard the crew announcement
Yes , long haul , get up , walk around , visit toilet , sit down , belt up :-)
Keeping your seat belt on at all times when you're seated on a plane is just plain common sense. Clearly, not everyone has common sense.
Is it tho? Imagine you knew nothing about airplanes and the fasten seatbelt sign turned off....you would very likely think that the airline just officially told you that in their extremely safety conscious opinion it is now very safe to remove your seatbelt.
And tbf to them it's not that unreasonable to think that, otherwise why even bother having a seatbelt sign? Why don't they replace it with an actually relevant sign?
@@Wintermute909 Just about anybody who flies has heard of air turbulence before, just like anybody who travels by car has heard of accidents. There are too many arrogant people in this world who think an accident will never happen to them until it does.
Listening to this while reading there are 30 injured on a flight from Spain to Uruguay due to turbulence...
Today? Is this the one that diverted to Brazil?
@@juliemanarin4127 Yeah, that one.
I've always wondered what happens to the food cart when siem turbulence is hit. I assume it doesn't hand some awesome magnetic switch to keep it down, and I don't see anything to lock it laterally under the seats, so... I can only assume pain results.
In a word, yes. But they are lighter than they used to be.
That was great! It is very informative and well presented.

I flew over to Singapore just over a week ago, there was enough convective turbulence over the itcz that made quite a few people unwell. But worse than that, there is a minority of people walking around even when the belts were on.
Over the tropics, there is a constant layer of cirrostratus, this can be very turbulent especially during the day. I tend to call that gravitational turbulence, or Kelvin Helmholtz waves.
If the sky is white, get those belts on.
I was shedding my tears when watching passengers SQ321 meeting their family. But burst out laughing like a maniac when I heard "shaving with a bad razor". That was totally unexpected! Great visual presentation as usual. Salute to your team!
I love these videos. They are informative and you can actually improve your English skills in a fun and decent way. Greetings from Germany
Thank you! Glad you think so
@@MentourNowlol I thought you were a native English speaker duo language speaker! I'm an American and you sound as though you have always spoken English!
Thank you very much for picking this important Topic up!👍 It´s again very informative and enlightening. - Btw.: There happened just today (July 1st, 2024) another Severe-Turbulence-Accident with 30 People injured, this time a B 787-9 from Air Europa while crossing the Atlantic Ocean. - So, yeah, much bad news about this stuff at the moment.
Brilliant video. In my career as an airline pilot I never even took my shoulder straps off. They move and are not restrictive so I always had them on. Why not. Lots of my colleagues would take them off as soon as we hit cruise though. As a passenger, if I was seated the belt was always on. These upset incidents will always occur for myriad reasons and airlines have been trying to convince everyone sitting down to always wear their seatbelt but sadly some forget, some take it as an insult to be told what to do and there are probably other reasons as well. For pilots the use of the weather radar to avoid growing convective cloud can be a bit of a fine art. The correct use of gain and tilt to expose potential nasty stuff comes with experience and of course you have to manually do this. Auto is not necessarily your friend. Now, I'm off to order a shaver! A close shave is good, if you are on the ground :)
I remember reading about multiple occasions in WW2 of allied aircraft flying in Burma literally getting destroyed by turbulence. On 10 August 1944 out of 16 Spitfires -8 were lost on one mission. See P 112 classic aircraft of WW2 Bison books 1981
You are such a pro. I am constantly impressed by the research breadth, quality, and synthesis. Thank you! I think this video will help my girlfriend better understand turbulence / be less stressed when it happens to us. Thank you!
I came back from the UK to Florida last week and the flight attendants made a special job of telling passengers to keep their seatbelts on during mild turbulence. I think this precaution is likely a result of this incident.
I fly between LA and the east coast of Asia and there's almost ALWAYS a lot of turbulence, so yeah, seat belt on is well ingrained.
Between HK and LA/SF several hours of turbulence shaking you too much to sleep is not uncommon. The areas of turbulence over the Pacific can be huge.
I love this channel!! I ALWAYS wear my seatbelt unless im in the bathroom...then i hold onto the sink. I want to know how Led Zeppelin partied...played piano...etc in their 707 with nothing ever happening to them? 😊 Thank God nothing happened to them...i love them❤
Great video from a great and reliable source! Stay fit.
Thanks, will try! 😂💕
Late 90’s or early 00’s, I slept across 3 seats on a flight from Falaraki to Newcastle, only got woken by a stewardess as we were on approach for landing. Videos like this have really opened my eyes
I'd use the seatbelt in the middle seat. Have it on loosely
Sounds like a dream!! 💭
Makes me wonder: why are hot drinks allowed on flights? In a bottle or other closed container it seems acceptable, but with many injuries from turbulence accidents being caused by burns, prohibiting hot drinks in open containers seems like it would improve safety
"How dare those airlines hinder my constitutional right to drink my coffee during the fligh?! .
It can spill and burn someone? I don't give a $#!, those are just NPCs. It can spill and burn me? I'm suing you either way, because I'm definitely not fastening those oppressive seatbelts."
😆
Latest turbulence event from Air Europa. A cabin video shows a passenger stuck to the ceiling!
Am I just noticing the video credits in the lower left? I like that, rather than just borrowing other people's video because we can.
I hate travelling if the weather is hot. We used to fly regularly from Birmingham International (UK) to Alicante (Spain) Every time you go over that mountain range that goes between France and Spain it don't half get choppy.
Close to two years ago, I read the aviation news in my country Taiwan, and there’s a coach pilot (… with his son🤔) flying their light aircraft, crashed into the field, and dead. Because the terrain in Taiwan can be super tricky, it can close to the mountain up to 15000 feet, and also close to the ocean with just few kilometers away. I immediately thought that it might caused by mountain wake turbulence. The updraft and downdraft in Taiwan should happen often in flying.
If that’s a light aircraft encountered that convective turbulence in that scenario, I guess that light aircraft would crash as well.
Clearly, keep seat belt on is right way to do.
Turbulence is always a much bigger issue for Cessnas and the like than for commercial airliners. OTOH they do not fly high enough to encounter jet stream related turbulence.
New video from Petter: I click, hit Like, then I watch. Never has a YT channel been as consistently excellent as this one!
Clear air turbulence (CAT) predictive tools have been evaluated in the Bast. Back in the early 2000s I was involved (FTE) in two research projects that employed special forward-looking sensors to sample the atmosphere ahead of specially modified test aircraft. One system was radiometer based and was mounted on a Falcon 20 test aircraft. The other was a LIDAR based system mounted on a Boeing 720B. Neither of these systems was commercially pursued however. We did evaluate these systems at typical airliner flight levels. Today, with many airliners being connected via L-Band and Ka-Band satcom systems, turbulent conditions in the airspace could be broadcast in real time-time to other suitably equipped aircraft. Areas of CAT could be identified and “broadcast” to airplanes operating in the same airspace. Modern digital radar systems such as the Honeywell RDR4000 are capable of sharing real-time atmospheric data in such a way. As you mentioned in this excellent video, there is a cost benefit trade-off involved. Existing aircraft radar systems are able to provide predictive wind shear advisories to crews during landing. Perhaps similar advisories could be provided thru the radar system. Time will tell (more research is needed).
I’m not pilot so I don’t have much knowledge in aviation but I read a few aviation forum posts saying that 2-3 airplanes ahead and behind of SQ321 avoided the potential convective region, ahead of time. I don’t know whether those planes made those decision based on the realtime weather update or made a very conservative preflight route to avoid turbulence based on forecast. But in either way, if they did something that lead a successful turbulence avoidance, perhaps the investigation should look into those planes’ data too. Perhaps protocols could be reviewed or revised for more conservative flight planning to achieve more successful avoidance of potentially injury-causing turbulence.
I don’t agree with saying this was caused by CAT. They were flying between thunderstorms. It was caused by storms. You can be affected by thunderstorm induced turbulence up to 50nm from storms.
Interesting. Very good imagery.
Thank you!
Dude Henson razors are amazing, I've saved so much money over the past two years. I have a huge box of razors (hundreds) that will last me probably as long as the razor. But the shave is so great and when the razor wears out, I have so many more and a fresh blade feel s so great. I don't know how much I've saved but it has to be over a thousand dollars over two years between me and my wife and yes, she uses it almost as much as me.
Fantastic Wx lesson. Watch out for those Cumulonimbus with Vertical Development.
As an aircraft maintenance engineer, i always tell people the same thing. Keep your seatbelt on
All in all the crew responded entirely correctly to this upset.
One thing worth bearing in mind for pilots used to operating in Europe is that whilst it's rare for storms to reach very high altitudes in Europe (60,000+feet) it's relatively common in the tropics.
The passengers that got thrown out of their seats only have themselves to blame.
It really annoys me that individual responsibility has been entirely abdicated by people who feel that they can ignore safety precautions when imense efforts and care is going into keeping them safe. Keeping seatbelts on (relatively loosely) is the least inconvenience.
Shaving even with a Hansen razor is probably not a great idea in the air either :-)!
I like how he is upfront a very effective solution, even a slightly looser seatbelt makes a night and day difference, yet can be comfortably worn overnight. In such an venture it will still hold you to your seat and you have every opportunity to react and tighten it, which you can’t do once you are in the ceiling…
Thanks for all you and your teams hard work, Petter! Looking forward to watching this video and coming weekend Mentour Pilot video!
I always keep the seatbelt on during the entire time. Even when it's just a little turbulence, I tend to lift quite a bit from the seat (tiny and light), so better to be safe than sorry.
I just took a trans-Pacific flight on JAL and noticed that they specifically instructed us to fasten our seatbelts over the blanket when we were using one, so the flight attendants could see that it was buckled.
This level of negative G force is something that thrill-ride fans dream of. If it didn't have the potential to seriously injure people, it could be fun. Of course, this is why roller coasters have not just elaborate restraints but also strict rules about securing loose items.
I had the terrifying experience of riding a ring coaster when nobody checked the restraints. I was definitely too small, and I had to hold the open roof frame so I didn't fall out past the restraints. I haven't been back on one since. No thanks.
13:51 Fun fact I was on UA57 with service from EWR-CDG the evening of 08 Jan 2020 landing in Paris on 09 Feb 202 and the BA 747 that crossed the Atlantic in 4 hours 56 minutes was just a few planes ahead of us. I remember seeing it while I was in flight. We had the second or third quickest transatlantic crossing on our 787-10 that evening, completing EWR-CDG in about 5 hours, landed 2 hours ahead of schedule, and I remember seeing a ground speed of .98 mach
I just want to add that LIDAR module costs are dropping so rapidly that a lot of cost-benefit analyses from even a few years ago are now really inaccurate.
I, as well, am surprised that there is not more mention of LIDAR costs dropping.
That's especially so as the study Petter quotes saying that LIDAR would cost more than it is worth was from 2002 - 20 years ago, when LIDAR was still an ultra-advanced experimental thing. LIDAR costs have nosedived since those days so undoubtedly this is now just plain wrong.
A bigger problem with LIDAR for detecting fast air movements is that it's not really reliable. The cost will continue dropping, but it's hasn't been getting more reliable lately...
Considering how high fuel burn is for large aircraft - unless your passengers are being treated in the US - I would think injury costs would be relatively low compared to added fuel costs of avoiding turbulence. (Not counting future decreases in ticket sales related to the injuries.)
I've experienced a a couple of turbulence where at best I'd get a bruise from striking the sidewalls with my head, possibly quite worse, had I not had my seatbelt on. Now I have a habit to fasten it whenever I sit, I don't even think about it. I question the sanity of people who don't put it on... Like, why?! It's not constricting in any way, you can barely even notice it, and it can quite literally save your life.
One of the reasons I avoid any flight that involves landing in Denver - every time, there’s been significant turbulence coming into that airport
I’ve been watching your channel for several years, and one thing I definitely learned was to keep my seatbelt fasten at all times. Honor most recent flight of Florida. I had to yell at my husband because he took off his seatbelt. He knows to leave it on at all times during the flight.
Weather is changing so flying also. Aviation on top.
Probably one of the best and most informative videos on your channel yet, can definitely see the huge step up in profuction quality. Good job.
Used seatbelts since "forever", except when visit "the office". When I say "forever" since I started working for SAS at FBU back in 1975.
A long time ago, when I was ~12, I went on my first flight from the UK to Munich to spend Xmas with my sister and her German husband. The whole family went, including my other big sister (we came in two batches of two girls with an 8 year break between #2 and me, #3 lol) with her husband. Mum was a pretty frequent flyer on this route, but she was terrified of it. (She was incredibly brave because whenever my sister needed her, she'd fly over asap.)
About half an hour or so before getting to the destination, my brother-in-law who was in the middle seat between Mum on the aisle seat and me at the window, needed to go to the loo. Mum was able to get up to let him past (she was a quite large and cuddly lady 😊), then she sat back down. He ended up in a queue - I think many people were planning to not need to stop in the airport!
The weather was not too bad, but by now we were in & out of a lot of cloud. It wasn't windy, and despite being on an older jet (even for the end of the '70s. Might have looked older than it was because it was Dan Air, if anyone else is old enough to remember them lol), it had been a smooth flight. I'd heard about turbulence - the typical "run over a pothole-full road" sensation - and was surprised to not have felt it. Until the plane literally dropped - a lot! Those in the loo queue had ended up in the air briefly and then found themselves on the floor. He had to crawl back to us and then get past Mum! She was as white as a sheet and grabbing hold of the chair so hard we couldn't get her to move. He couldn't get past her so she _had_ to stand! Eventually, despite being thrown from side to side, going back up and dropping (it lasted a good few minutes!), we were able to unpeel her hands, and get her up enough so I could pull her to the middle seat. We all buckled up, but by then it was essentially over.
During the worst of it, the captain (I assume) came over the tannoy and yelled (no exaggeration!) at everyone to sit down and buckle up, and finished with "Girls, sit down!" to the stewardesses. There was no "Ladies and gentlemen, we are currently experiencing a bit of turbulence, it's perfectly normal but please sit down and put your seatbelt on," it was full-blown orders with terror in his voice!
Me, never having experienced turbulence, just thought to myself "Ah, so this is what they mean." Believe it or not, I wasn't afraid! (I am now as terrified of flying as Mum used to be, but I don't know why.)
A few years later I flew over on my own with BA and we had the "pothole" turbulence and the captain came on, introduced himself and did the calm sort of speech I'd been expecting before. Weirdly, I liked that because it made me feel like there was something "solid" beneath us! 😂
I really felt for the people on the Singapore flight. That must have been horrendous!
@@y_fam_goeglyd Very engaging story, felt like I’m watching a little movie scene. Good to know all your family members and yourself survived the incident 😅
I just saw the news that Boeing reached an agreement to buy Spirit Aerosystems. I look forward to your video about it. Regards
You need a video about what you already know?
I never understood why so many people don't use their seatbelts when sitting! When you do it quite loose it doesn't even hinder you with any movements but it can save you when the plane gets into serious turbolences.
I always sit strapped in, and honestly, it never occurred to me to wear it loosely.
I guess it is the same for the non-belters. Maybe something airlines could remind passengers of!
Really love your videos ... it makes our family feel less anxious & safer travelling by aeroplane thank you Sir !👏👏👏👍👍👍
I mean instead of spending millions of dollars researching high tech radar, they could just spend a few bucks per seat and replace the sign that implies it is safe to unbuckle your seatbelt with a sign that says you are now allowed to stand up & go to the toilet (or something similar).
❤ TBH, as an overweight person, I have just pretended to buckle my seat belt by tucking it under my shirt so the FAs can't tell on many occasions. Started watching your channel during pandemic and realized how dumb it is to worry about my pride instead of my life.
If you wish, you can ask a flight attendant to provide you with a seatbelt extender, that may offer you a safer and more comfortable flight experience.
@@Eternal_Tech
I do now. It was my pride that stopped me from doing so before.
As a meteorologist, I can tell you unequivocally that turbulence is not getting worse. The jet stream has and always will result in turbulence, and flying around thunderstorms will always result in turbulence. We are flying around in and ocean of air. Wind shear, waves, and instability exist all over the place. That has not changed and it never will change.
Meteorologists can be wrong
So, not a climate scientist/ researcher. Ok.
As a frequent flyer of 38 years, I can tell you from my own experience - I experience more turbulence in flights and also more extreme turbulence in flights. Climate change is real. It is scary you are a meteorologist and this is your take. Don't let your ego from your expertise blind you from reality. Best,
I noticed flying through any cloud tends to be turbulent ~ there's a reason they're shaped fluffy and not stringy.
@@RocketboyXMeteorologists are that though. It's their job to be able to understand what is going on in the atmosphere due to convection.
@ 24:42 Absolutely Yes. Isn't it mandatory to fasten seatbelts when driving cars? Like the advert used to say " Don't fool yourself, Speed kills". 10/10 important video as always Petter❤
Clicks every time he drops a video ❤
Great stuff!!
