Well done ITV news for asking the questions I was keen to get answers to. 👍
can we do the same interview, for car accidents. :) it might calm people down on flying.
You know, I recall flight attendants always saying wear your seatbelts at all times when you’re seated. If you sleep on a long haul flight like SQ321, they ask you to put the belt over your blanket so they don’t have to disturb you to check. I know you’re still at risk when standing and moving around, but it minimises your exposure time. And crews can normally detect it a few minutes in advance and turn on the seatbelt sign. For those who wonder why the pilots can’t just change direction at will, aircraft are following a specific track, and unless they have an emergency to deal with, they can’t just change heading without checking there isn’t nearby traffic they’d endanger or even collide with.
Anyone that has been on a long haul flight, will tell you how incredibly boring they are ! So maybe pilots should do the occasional nose dive, barrel roll or a loop de loop to liven the flights up and excite the passengers 👍🏻.
...that made me laugh
The flights are boring (Aussie to Europe) but there are some exciting events that I could do without.
Not fun for whoever's in the loo
I know the feeling… scary as hell!!
This is why Pilots are always buckled up.
Only lap belts in the cruise.
@@mitcho04 Less risk opf passengers strangling themselves
@@AmbientShores I meant for flight crew.
Exactly. For pilots it’s 100% of the that at the lap straps are worn . For takeoff & landing the full 5 point harness. Imagine if pilots don’t do that and both get knocked unconscious in the first 2 seconds- it would be curtains for everyone onboard!😮
It is simple.Wind travels in different directions at different levels.Where these levels meet is called "wind shear" , the greater the difference in speed causes turbulence , so since hot air rises and cold air sinks the nearer the tropics the greater the chance of severe turbulence.
Scary stuff!
Did he say 4 billion people fly every year? If so that's half the entire worlds population. Never thought it'd be such a massive figure.
I am pretty sure he could have meant the number of times people flew annually. So it could be both frequent flyers and first time flyers.
Not sure where he got that figure. But the total is just over a billion air passengers annually worldwide .
It's not 4 billion unique people; just that there are 4 billion passengers, which can include your return trips for example.
People are always going to ask questions when something like this happens, particularly when it's in the same area a similar aircraft completely disappeared a few years ago, because there are about 8000 planes in the sky at any second on any day and this isn't happening more frequently and because they regained control before it happened again.
2:40 "..bend the wings through 90 degrees" - I really want to see a video of that. The wings must be made of rubber.
All over UA-cam. Look up 777 design upper load limit testing. You’d be sure to find one. Design upper load limit is the classification of stressing a plane to 1.5x what can reasonably be suspect to be found in actual flight in terms of stress.
p;enty of videos of it i think the 787 is the most impressive
@@mitcho04 According to Boeing, tthe max 777 wing flex is 9 m, so if total width of wings = 64.8, and cabin width = 5.87m, then the max angle of flex is arctan(9 / ((64.8 - 5.87) / 2)) = 16.98 degrees, which is very far from 90 degrees.
Just some turbulence, nothing to be worried about-ACKH
There were already reports of nearby CBs, so why didn't captain take evasive actions?
You know, I recall flight attendants always saying wear your seatbelts at all times. If you sleep on a long haul flight like LHR-SIN, they ask you to put the belt over your blanket so they don’t have to wake you to check. I know you’re still at risk when standing and moving around, but it minimises your exposure time. And crews can normally detect it a few minutes in advance and turn on the seatbelt sign. Don’t forget, aircraft are following a specific track, and unless they have an emergency to deal with, they can’t just change heading without checking there isn’t nearby traffic they’d endanger or even collide with.
I’m flying back to the UK from Thailand this evening 23rd of May, this worries me a bit, it will be seat belt on for the full flight except for toilet visits.
You'll be safe for sure
You wouldn't disconnect the autopilot at 36,000 ft - the aircraft is in such a small envelope that many authorities forbid hand flying above 29,000ft
First of all, if the turbulence is severe enough and the movement of the airplane great enough, the autopilot will disengage automatically, but with an extreme vertical movement of the airplane, the pilots will definitely take manual control for the simple reason that leaving the autopilot engaged could make things worse because the autopilot will try to return the airplane to the set altitude again which would not necessarily be the desired action you want if the airplane has just dropped several hundred feet.
Every airline has their own procedures for this.
@@TheChiefEng And they're trying to programme self-driving cars where the variables are 1000x more.
Not really. If you have runaway nose up trim, you'd switch off the autopilot, as an example.
The first thing you do in severe turbulence is disconnect the auto pilot, set a certain thrust called turbulence penetration thrust and aim to minimise altitude deviations.
why you should wear your seatbelt sat down, even when the sign is off... Sign off just means you can get up.
Flying considered safe now no more.
it did not fall half a mile please correct that the entire differential of height was 400-600 feet
When you're on that plane that's half a mile😂
Look at the chart at 1:29
@@daniel72_751 yeah and……
@@daniel72_751 if you mean the grey line thats verticle rate not the actual change in feet
@@daniel72_751 it got pushed up around 400 feet probably by an updraft then down by about 400 the actual movement wasnt very big at all but at 600mph of course when that moves in a direction at speed anything that isnt secured is dlying around
it wouldnt matter if was boieng cesna anything would have be catastrophic
Everyone is an expert apparently
He had a heart attack for.
Why do planes fly so high up there...37000 feet... is 25000 not good enough...almost always it happens at higher heights
Higher flight level means less air resistance = better fuel economy. And usually less turbulence. But it can happen at any flight level current civilian aircraft can reach. Also note that it’s incredibly rare to have a serious incident such as this, which is why it’s newsworthy. How many car crashes took place during the 13-odd hours of that flight? With far higher numbers fatalities in many cases. Sense of proportion matters, people.
Still planes could be safer if it's fall down turn to capsule..
Slow news week?
It was bad, so many people injured and one gentleman died 😞
@@rhianpainter6196 he died of a heart attack I believe!
It gets all bouncy bouncy, then you get your skull smashed in on the aircrafts internal fittings.
Cant think why my comments should be pulled on here ? Ideas ?
Ive already seen news outlets blaming global warming 😂
Stormy weather across the ITCZ has increased in recent decades.
Curious….how does one become an “expert” in aviation? 🤔
Like inflation
Next week on ITV - Why cornflakes absorb milk....
Play flight simulator you know
" Aviation expert "??? Sounds rather vague.
BS baffles brain...
Sounds like global cooling to me
Must be a slow news week if this is the kind of stuff itv news is getting up to
Litterally nobody has asked what the heck turbulance is
If you can’t spell it, I’m assuming you don’t know what it is.
Welcome to bottom of the barrel
More like pilot put in wrong vertical speed and pressed engage. -6000 instead of -600.
Tell me you’re not a pilot without telling me. 🤫
Can you move on already
Does cloud seeding has any repercussions on this? Asking for a friend! 🤬
