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.

Around Bay of Bengal actually.

That rapid change of speed was something. The fact The plane hold its shape is even amazing

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.

Air turbulence in southeast Asia including around Singapore can be significant. This incident showed the real importance of wearing your seatbelt.

At any point the movement up and down was 400ft not 6000ft. Many people are mistaken

@ssuwandi3240

27 күн бұрын

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.

Good educational video !

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.

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

Informative video Thanks

what an insightful information 😊😊

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

Excellent job

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

in a matter of 3 seconds that is insane.

salute to the pilot. In that moment, he knows what to do, and didn't give up and tried saving the entire plane.

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?

I still have faith in Singapore Airlines. My condolences to the passengers and their families.

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.

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.

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.

@AWXPlays

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/

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.

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?

This was the best airline in the world can offer "AIR TURBULENCE"

Good video analysis. Hats off to the Pilot for managing to land safely despite the tragic incident.

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

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.

*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*

600 or 6000ft? im confused now

@AWXPlays

27 күн бұрын

no need to be confused, the 6,000ft descent occurred AFTER the incident already happened, and this descent was INTENTIONAL and SAFE in order to prepare for the diversion to Bangkok. The actual incident itself saw the plane climb to a maximum altitude of 37,400ft before they levelled off again at 37,000ft. HOWEVER, what made this incident so severe is not so much the altitude, but rather, the RAPID and SUDDEN CHANGE in altitude. This is measured by the vertical speed of the aircraft, that is, how fast the aircraft is climbing/descending. In this case, the vertical speed, measured in feet per minute (fpm), had rapidly and suddenly changed multiple times over roughly one minute, with the most rapid change in that minute being a 9-second period where Flightradar24 ADS-B data recorded this: 07:49:43 UTC → +1,664 fpm 07:49:46 UTC → +640 fpm 07:49:49 UTC → -1,536 fpm 07:49:52 UTC → +896 fpm this is also probably the moment that the passengers got lifted up before being slammed back down. Causing the severe injuries. Hope this clears things up for you, if it doesn't and I don't reply, I hope others can make it simpler/clearer for you!

Do passengers have to resort to wearing helmet and bubble wrapping oneself when leaving the seat for the toilet?

Flying around the _"mildly"_ bad weather is more financially costly than a straight thru it. Simple as that.

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

Only the pilot flying are required by law [air law] to have their seat belts on at ALL times. The pilot not flying, PNF [aka, pilot monitoring] can remove it if they want to. Usually when it's busy, communicating with ATC, etc, PNF would still have their seat belts on, when it's in cruise or light workload, they may unbuckle for awhile. 74Gear channel, a 747 cargo pilot did talked about this before though I can't remember the title of that video.

It wasn't clear air turbulence though.... they clearly flew right through the weather if you cross reference the weather data at the same time as the turbulence location and time..
