Finally a reasonably accurate description of what happened, after many incorrect stories about a sudden/steep 6000ft drop, which was just a controlled change of flight level.
How come here there is a more accurate description and in an interview with a spinal doctor you still talk about a 6000 feet drop? Very strange that CNA staff tell different stories and also not professional
@@daniel773 I am not concluding anything about CAT. What I wrote is regarding another video of CNA, talking about a sudden 6000ft drop, while the decent of 6000ft (from 37000 to 31000 ft) was a controlled descent as part of the path to Bangkok. And some other mistakes. There are lots of news items with lots of nonsense and lots of comments are clearly from amateurs as well.
@@zzzowie it does not matter, what does matter is that due to pollution and climate change we will be seeing more cases of severe turbulence. this is the problem
The video and explanation are awesome. The SQ pilots in the flight managed to control that 777-300ER in that few seconds of extreme and irregular altitude change (imagine the G-force and pressure exerted on their bodies, even they have their harness fasteened) are super-heroes! The pilots and the training they received deserve our big respect and deep appreciation.
I will never forget the flight from Schipol to Aberdeen over the North Sea when we hit clear air turbulence. The plane went into a freefall and you could hear and feel the pilots trying to gain control of the aircraft, trying to bring the nose up. Once everything settled down the pilot explained what had happened that we were hit by a 140 km crosswind and went into a freefall of 600 feet before they gained control. Terrifying experience.
There was no CAT in the area because the Jetstream was extremely weak. There was however embedded storms forecast on the flight path. The aircraft blundered into the top of a thunderstorm.
obviously not that well trained. probably no fuel left to take evasive action.. Seen it in Europe for years with budget airlines. Just cost cutting.... Never thought Singapore could become one of those
I don't think that would be necessary imo. It would be all the same answer, because it's logical. They had their seatbelts on even when the seatbelt sign was off.
Yeah, 40 people are not going bathroom at same time. I keep belt on entire flight fo years 300+ miles per hrs in near freezing temperatures things occur fast
Impossible to predict clear air turbulence with current technology. Always fasten your seatbelt at all time even if the seatbelt sign is off, unless you are going to the loo.
The 400dt decending happened several times because the radar tracking showed a 6000ft drop in 2 minutes. Simply means the pilots were looking for a clear path with less air pockets. It would be easier to do nearby the towers during landing. Abs a great call to divert to BKK.
I'd have to assume pilots got injured as well during this, the fact they managed to remain calm and bring the plane to stability again, then land in Bangkok safely should be highly commended
think properly and critically, was it pilot error or perhaps error in flying instruments that caused the sudden drop? the investigation results are not even out yet
Actually, the structural elements of the airframe are not particularly stressed in such conditions because it is simply being carried in the direction of the airmass. However, the untethered elements within the airframe are subject to the inertial forces from rapidly changing direction, i.e. carry-ons, food trays, bodies, etc. It's as if you were riding on a roller coaster without any restraint bar or harness.
yes, I think an analogy could be that it's like a snow globe, where the globe represents the aircraft, and the snow flakes represent things that aren't secured on the plane. When the snow globe is shaken, the snow flakes are thrown about within the globe, however, the globe itself is fine
Great depiction and rubbishing the theories of 6k ft drop in a few seconds. While now we are left to analyse what could have been done better to avoid severe turbulence, but none think of the upside that maybe pilot controlled the aircraft well enough that they didn't lose control to let it crash in such a steep height it went to incline. They managed to bring the height back to the original even after hitting the unexpected, saving many other lives. I hope that this won't have happened, but I also feel thankful that many families saw their loved ones returning home safely.
I remember when I was 16 years old going on holiday to Singapore from the UK this exact same thing happened over 10 years ago. It was terrifying and it was my first flying experience
wow, i flew to london through the same path before for a family holiday, never knew such weather can happen at such a dangerous level before around thailand
Thank you for the post/video. Very informative and helpful. Clear and well presented with animation which helps understanding about air turbulence and the Clear Air Turbulence.
Seat belts should be fasten at all times especially eldery tobe safe ......but many many times passengers doesnt listen to instruction thinking is no big deal without seat belt when accident happen too late
Might be the right time to install the same seatbelt warning chimes we use in cars in planes. If you don’t buckle up you will be continuously reminded (and annoyed) by the warnings. To not annoy the other passengers because of the sheer amount of seats they might use a 10-20 second delay that begins with a flashing light and then 30 seconds later starts chiming otherwise imagine the sound of multiple chimes!. Airlines constantly remind passengers to fasten their seatbelts while seated but we take non-turbulent flights for granted.
Because it's already mentioned in the video, CAT (clear air turbulence) that caused the turbulence is not detected by current technology and there is nothing to be shown. The weather radar can only detect water particles in the atmosphere.
when there is no susstantial check or reference from the plane's data recorder or black box...how can these consultant make irresponsible remarks. lets all be patient and wait for the investigation by the pros before any speculation.
The heck are you talking about? 🤦🏻♂️ It is clearly CLEAR AIR TURBULENCE. 🤦🏻♂️ And the graph shown of the drop is literally recorded based on the flight records. What else do you want?
4 ### Principle of Inertia 1. **Inertia**: - According to Newton's First Law of Motion, an object at rest will remain at rest, and an object in motion will continue moving at the same speed and in the same direction unless acted upon by an unbalanced force. - In the case of an airplane, both the plane and the passengers are moving forward at the same constant speed. If the plane suddenly moves downward due to turbulence, the passengers will initially continue moving in their original direction and speed due to inertia. ### Relative Motion 2. **Relative Motion**: - When the airplane suddenly descends in turbulence, it accelerates downward. Passengers who are not wearing seatbelts will not immediately follow this downward acceleration because their bodies will initially remain in their original state of motion due to inertia. This creates a momentary situation where the airplane moves downward relative to the passengers. 3. **Feeling of Upward Motion**: - For an observer inside the airplane, it appears as if the unbelted passengers are moving upward, but in reality, the airplane is moving downward relative to them. The ceiling of the cabin moves downward faster than the passengers, making it seem as if the passengers are being thrown upward. ### Example Scenario Consider an airplane suddenly encountering a downward air current: - **Movement of the Airplane**: - The airplane suddenly accelerates downward. - **Movement of Unbelted Passengers**: - Due to inertia, the unbelted passengers will not immediately accelerate downward; their initial vertical speed remains unchanged momentarily. - **Result**: - The airplane's floor descends faster than the passengers. To the passengers and observers inside the airplane, it appears as if they are being lifted out of their seats and hitting the ceiling. ### Simplified Analogy Imagine standing in an elevator. If the elevator suddenly drops quickly: - Due to inertia, you will momentarily remain in your original position while the elevator moves downward. - To you, it feels as if you are being lifted off the ground. ### Conclusion Unbelted passengers hitting the ceiling during turbulence is due to the airplane's sudden downward acceleration. Because of inertia, the passengers momentarily remain in their previous state of motion (not accelerating downward as quickly as the plane). This makes it seem as if they are being thrown upward relative to the rapidly descending airplane. 3:25
*Perhaps can interview the Adelaide man still in BK Hospital and his wife in ICU suffering severed spinal cord injuiry with no sensation below her waist*
Man, this is getting quite a lot of attention for an accident that only killed 1 person. if you've ever been stuck in economy you know this could have been magnitudes worse. there are car crashes happening every month with probably same kill and injury rate, just think of how safe airline travel is when an accident like this is so rare it takes up a week in the news cycle
@@wilshen1992 Yes, but they survived. Those who were injured didn't wear their seatbelts regardless of the warning. This turbulence wasn't sudden, it grew slowly until it became chaotic. People NEED to wear their seatbelts at all times.
Clearly a lot of people just watched certain parts of videos, and then suddenly become air aviation expert, assuming the pilots made mistake: 1. It was a clear day without any severe weather report - Flights are fixed on the given route and attitude, unless they are being hailed and requested to redirection due to weather. Also, weather radar on plane doesn't detect turbulence, instead, display the weather and pilots will try to navigate out of it. If it's a clear day, there's nothing on radar. 2. The world's weather is fucked up now, just in SEA alone, we can experience severe heatwave, then out of sudden thunderstorm with high speed winds blown down trees. Watch how many trees causing death in Malaysia in just past 1 week. 3. The video talked about how the plane being thrown to high attitude and drop within 3 second. No pilots can perform that maneuver within split 3 second, it's not a fighter jet.
The better term would be "Climate Change" since the cold side of the spectrum would get worst in certain parts as well. Some already cold area/regions may get colder or last longer.
Unfortunately, there was no CAT there at the time. There were huge thunderstorms in the area which may have not been avoided properly. Very much like the AF tragedy from Rio. They are very lucky 🙏🏼
as someone who had a chance to travel to Europe from PH and back for 4x, every time the plane crosses this area, I always encounter turbulence.. is this area prone to turbulence?
A low-pressure area is likely to form over the southwest Bay of Bengal around May 22 and it is likely to move initially northeastwards and concentrate into a depression over central parts of Bay of Bengal by morning of May 24, officials tracking the depression said on Monday. There are chances that the depression will intensify into a cyclone, the first cyclone during this pre- monsoon season, they added.
There is seldom clear skies over the Bay of Bengal. I think the pilot flew through some heavy storm clouds. There was a graphic where other airplanes were diverting around, but Singapore air fly straight line. Not saying it was a pilots mistake, but should be more considerate about passengers.
Did you watch the video? It was clear air turbulence with no detection possible. It was not due to poor weather which could have been detected and avoided.
*Hope CNA can do animation graphic video to show how passengers got lifted up to the ceiling and thrown door to the floor during the turbulence cos need to see the level of the impact and gravity*
Conventional weather radar will not help. But modern LIDAR and Doppler radar systems on aircraft can detect differences/ shifts in air density indicative of turbulence at a range of approximately 10 to 20 kilometers ahead of the aircraft. Given the cruising speed of a typical commercial aircraft at between 500 to 600 km/h, there would be a time interval of slightly more than 2 min between detection to when the turbulence hits. This would give sufficient time for the pilot to alert the passengers, especially in situations where there is CAT.
It seems as though these modern systems have NOT been implemented for commercial aviation use, I tried digging for information on this online but only managed to find some systems like the UV Rayleigh LiDAR and a Direct Detection Onboard UV LiDAR , being used only in a RESEARCH context. These research have shown that the LiDAR systems actually work quite well to detect turbulence in aerosol depleted atmosphere (like a CAT). This leads me to think that although the technology exists to detect CATs while at high altitudes (i.e. within 3,000ft above and 7,000ft below the tropopause), this technology has yet to be implemented for use in commercial aviation, hence, the argument is made that this extreme CAT event could not have been detected/avoided/predicted on the weather radar in spite of the existence of these LiDAR systems. Please let me know if there is information stating otherwise and if anyone has any thoughts on this, please let me know! Here are the sources I've read: www.researchgate.net/publication/265059512_A340_flight_test_results_of_a_direct_detection_onboard_UV_LIDAR_in_forward-looking_turbulence_measurement_configuration pubmed.ncbi.nlm.nih.gov/27857327/
Yes, you are correct in that the use of LIDAR to detect CAT at cruising altitude is mostly in the experimental or developmental stage currently. Hopefully, progress will be made in this area in the near future for actual application for CAT detection in commercial airlines at cruising altitude.
Yes,, looking at the graphics,, the pilots were commendable,, they were, able to manage the plane to at least make an emergency landing shortly after the horror situation,,, They handled the horrifying flight very professional indeed, thanks to these pilots Fasten your seat belts at all times during the flights.
On that day it was raining heavily in Bangkok and Myanmar area . Definitely it would have been a thunderstorm in that area . In addition to that , may and June is the rainy season in Thailand and Myanmar. I still don’t believe that it would have been a clear air turbulence . Moreover that route isn’t that busy during day
@@harleydavis3814 oh yes I had word with my friend in Bangkok on that day and she said that it was raining very heavily since morning in Bangkok . It was a stormy ⛈️ weather
Sg airline and pilots to be held accountable please. Proven that the plane made a huge sudden drop which caused many to be severely injured and one death. Singapore airlines safety rating dropped and needs to be reviewed. Lawsuits incoming. Gross negligence.
But boeing has sensors even clear turbulance, i suspect pilot didnt report to passenger to go back n buck up early..its the pilot action that makes that slow reporting..
At this time of the year the pilot should try to avoid the intertropical convergence zone itcz especially when they know a storm is already brewing ahead. No expert but just saying.
@@RA-wp6th up to you, you don't want to secure yourself and anything bad happens dont blame the airline. blame yourself for not taking care of your own safety.
Seatbelt, seatbelt. Put them on as much as possible during the flight. It doesn't have to be super tight. Loosen it a little so you don't feel like a python is wrapped around your waist. It can help you during situations like this
*Turbulence is getting worse due to climate change and its advisable to retrain all airline crews and pilots on how to handle and react swiftly when such incident occured*
Exactly, but hey! they will tell you over and over that such thing as climate change doesn´t exist, I have been a very frequent flyer for decades, and turbulence is way more common than ever in the same routes, with better planes, but they will still tell you there is no climate change or consequences for it.
So if there is no way of knowing clear air turbulence, does it mean its doomed for human mankind to fly? Whats does centuries of flight and engineering teach us about overcoming such obstacles?
Wear seatbelt at all times, except when you need to get to the washroom.... When you are sitting there, what's the incentive for not wearing it... So just strap on and save your head and beyond!!!
but please pilot be honest with the controller, if you want direct for shortcut or true weather in front of you. the controller have no objection for you to deviate due to weather and if you want the shortcut also the controller can give, but sometime it will increase the workload of controller and can effect the safety of other aircraft so please be honest

Thank you.
Actually, the structural elements of the airframe are not particularly stressed in such conditions because it is simply being carried in the direction of the airmass. However, the untethered elements within the airframe are subject to the inertial forces from rapidly changing direction, i.e. carry-ons, food trays, bodies, etc. It's as if you were riding on a roller coaster without any restraint bar or harness.
yes, I think an analogy could be that it's like a snow globe, where the globe represents the aircraft, and the snow flakes represent things that aren't secured on the plane. When the snow globe is shaken, the snow flakes are thrown about within the globe, however, the globe itself is fine

crazy rollercoaster ride
I still have faith in Singapore Airlines. My condolences to the passengers and their families.
The message is: keep your seat belt on at all times. Almost all the injured weren't wearing theirs.

4 ### Principle of Inertia
1. **Inertia**:
- According to Newton's First Law of Motion, an object at rest will remain at rest, and an object in motion will continue moving at the same speed and in the same direction unless acted upon by an unbalanced force.
- In the case of an airplane, both the plane and the passengers are moving forward at the same constant speed. If the plane suddenly moves downward due to turbulence, the passengers will initially continue moving in their original direction and speed due to inertia.
### Relative Motion
2. **Relative Motion**:
- When the airplane suddenly descends in turbulence, it accelerates downward. Passengers who are not wearing seatbelts will not immediately follow this downward acceleration because their bodies will initially remain in their original state of motion due to inertia. This creates a momentary situation where the airplane moves downward relative to the passengers.
3. **Feeling of Upward Motion**:
- For an observer inside the airplane, it appears as if the unbelted passengers are moving upward, but in reality, the airplane is moving downward relative to them. The ceiling of the cabin moves downward faster than the passengers, making it seem as if the passengers are being thrown upward.
### Example Scenario
Consider an airplane suddenly encountering a downward air current:
- **Movement of the Airplane**:
- The airplane suddenly accelerates downward.
- **Movement of Unbelted Passengers**:
- Due to inertia, the unbelted passengers will not immediately accelerate downward; their initial vertical speed remains unchanged momentarily.
- **Result**:
- The airplane's floor descends faster than the passengers. To the passengers and observers inside the airplane, it appears as if they are being lifted out of their seats and hitting the ceiling.
### Simplified Analogy
Imagine standing in an elevator. If the elevator suddenly drops quickly:
- Due to inertia, you will momentarily remain in your original position while the elevator moves downward.
- To you, it feels as if you are being lifted off the ground.
### Conclusion
Unbelted passengers hitting the ceiling during turbulence is due to the airplane's sudden downward acceleration. Because of inertia, the passengers momentarily remain in their previous state of motion (not accelerating downward as quickly as the plane). This makes it seem as if they are being thrown upward relative to the rapidly descending airplane. 3:25

One bad day planes just can't fly anymore because of climate change.
turbulence happened years ago, fell 100m, too bad, 20m is almost nothing
It was reported other aircraft deviated from their original flight path due to the bad weather but SQ321 did not
But there wasnt bad weather hence "clear air turbulence"
Unfortunately, there was no CAT there at the time. There were huge thunderstorms in the area which may have not been avoided properly. Very much like the AF tragedy from Rio. They are very lucky 🙏🏼
There no 3rd party investigation..need to see the radio cockpit, speed recording, sensor recording to determined what really happen

This leads me to think that although the technology exists to detect CATs while at high altitudes (i.e. within 3,000ft above and 7,000ft below the tropopause), this technology has yet to be implemented for use in commercial aviation, hence, the argument is made that this extreme CAT event could not have been detected/avoided/predicted on the weather radar in spite of the existence of these LiDAR systems.
Please let me know if there is information stating otherwise and if anyone has any thoughts on this, please let me know!
Here are the sources I've read:

Yes, you are correct in that the use of LIDAR to detect CAT at cruising altitude is mostly in the experimental or developmental stage currently. Hopefully, progress will be made in this area in the near future for actual application for CAT detection in commercial airlines at cruising altitude.
people love visual
great works
Yes,, looking at the graphics,, the pilots were commendable,, they were, able to manage the plane to at least make an emergency landing shortly after the horror situation,,,
They handled the horrifying flight very professional indeed, thanks to these pilots
Fasten your seat belts at all times during the flights.
I suspect negligence of pilot action before it moves to turbulance n can be avoided.
They flew into a thunderstorm. Not CAT. Pilots can accidentally fly into thunderstorms. This is just PR trying cover pilot error
On that day it was raining heavily in Bangkok and Myanmar area . Definitely it would have been a thunderstorm in that area . In addition to that , may and June is the rainy season in Thailand and Myanmar. I still don’t believe that it would have been a clear air turbulence . Moreover that route isn’t that busy during day
Correct
There were Thunder cells in that area but yet there was Meal Service
Aka sq is simply useless.
Yeah I remember some crazy lightning and thunder storms the last few days in Bangkok, I think this weather had some effect in that area
@@harleydavis3814 oh yes I had word with my friend in Bangkok on that day and she said that it was raining very heavily since morning in Bangkok . It was a stormy ⛈️ weather
Terbulance usually around Burma and Thai airspace..plane have deep decend which is very dangerous
Informative video
Thanks
This was the best airline in the world can offer "AIR TURBULENCE"
Sg airline and pilots to be held accountable please. Proven that the plane made a huge sudden drop which caused many to be severely injured and one death. Singapore airlines safety rating dropped and needs to be reviewed. Lawsuits incoming. Gross negligence.
This Plane is Well Built … Consider to Order More of such Planes 😊
400 ft is less than the tallest rollercoaster
It flew into a storm cell. You need to be upfront
Let's always do alot of good ❤️
So how big was them ups and downs? And how was the plane pushed upwards. Downwarss is understandable
But boeing has sensors even clear turbulance, i suspect pilot didnt report to passenger to go back n buck up early..its the pilot action that makes that slow reporting..
At this time of the year the pilot should try to avoid the intertropical convergence zone itcz especially when they know a storm is already brewing ahead. No expert but just saying.
You should wear your seat belt. It's in the clauses. You accept it when board
For an 18 hour flight?
@@RA-wp6th yes... aside from the 10 minutes (5+5) you go to the toilet and maybe extend it with some leg exercise.
@@RA-wp6th up to you, you don't want to secure yourself and anything bad happens dont blame the airline. blame yourself for not taking care of your own safety.
@eulogp9888 says someone who never flies for 18 hours of flight
@@Fujiwara.Takumi1 It sounds like you have never flown on a long distance flight
.....and many other flights around the same timing and route are fine?.....
Seatbelt, seatbelt. Put them on as much as possible during the flight. It doesn't have to be super tight. Loosen it a little so you don't feel like a python is wrapped around your waist. It can help you during situations like this
Yes seatbelt all the time. Wear helmet when going to toilet may help.
Just curious, why land in Thailand instead of Myanmar? Were the medical services and specialists better in Thailand?
Junta leaders even flew to Thailand to seek medical treatment as well as rich Burmese tycoons. Google Thailand medical hub.
Superb crew members ❤
Remember...Allah can give and also take back what was given...
Right into the eye of the brewing thunderstorm.
*Turbulence is getting worse due to climate change and its advisable to retrain all airline crews and pilots on how to handle and react swiftly when such incident occured*
Exactly, but hey! they will tell you over and over that such thing as climate change doesn´t exist, I have been a very frequent flyer for decades, and turbulence is way more common than ever in the same routes, with better planes, but they will still tell you there is no climate change or consequences for it.
The same thing happened with Qatar airlines enroute to Dublin via turkey. Im not sure if Turkey is part of mansoom effected region..
So if there is no way of knowing clear air turbulence, does it mean its doomed for human mankind to fly? Whats does centuries of flight and engineering teach us about overcoming such obstacles?
God bless not much severe incident except for the two death and some injury
Wear seatbelt at all times, except when you need to get to the washroom.... When you are sitting there, what's the incentive for not wearing it... So just strap on and save your head and beyond!!!
but please pilot be honest with the controller, if you want direct for shortcut or true weather in front of you. the controller have no objection for you to deviate due to weather and if you want the shortcut also the controller can give, but sometime it will increase the workload of controller and can effect the safety of other aircraft so please be honest
No Way,
There is no CAT where there is no jet stream
how is aviation analyst instead of a pilot an authority to speak on this? cna, u ok or not?
