SQ321 incident: Aviation analyst explains turbulence scenarios

One person has been confirmed dead and multiple others injured, after a Singapore Airlines plane made an emergency landing in Bangkok's Suvarnabhumi Airport. Flight SQ321 was flying from London's Heathrow Airport to Singapore when it encountered severe turbulence and was diverted to the Thai capital. The Boeing plane was carrying 211 passengers and 18 crew. Thai authorities are set to hold a presser to address the incident. Mr Alvin Lie, an independent aviation analyst, shared more about different turbulence scenarios.

Clear air turbulence! Now that’s something for you to know. It’s more dangerous than experiencing actual air turbulence because you have no prior knowledge of it coming and are ill-prepared for it. When the pilot says to fasten your seatbelts, take it seriously and DO IT! I reckon it’s best to be fastened to your seat 💺 all the time until it’s really necessary to go to the toilet! And make sure to make it quick at the restroom and get back to your seat and get fastened! 😅

My worst experience of turbulence was a sudden drop of about 2-3 seconds flying thru bad weather from Jakarta to Singapore. And the drops happen many times along the trip. Not too scary for myself having done airborne jumps but very frightening for average individuals and children on the flight. And that was when we are EXPECTING turbulence as the pilots had warned us we’re flying thru bad weather. But turbulence causing the aircraft to drop from average 30,000 ft to 6,000 ft is almost like doing skydiving, worst is not expecting it while flying in CLEAR WEATHER! Only difference is the pilots managed to keep the aircraft IN CONTROL and land safely. That in itself…my utmost respect to the pilots!!

[@dominicbrant1968]

Senior Flight Commanders are saying this turbulence is a normal event. The descent was normal. What is at issue is the initial 'bump' and passengers not being secured.

[@wifferstess2824]

My uncle, who flew for SQ as a captain before he retired, says that turbulence is a fact of life when flying, It's no different than a boat at sea. One of his funnier stories was he was called to come see a passenger who asked him to make the plane stop shaking.

I flew to KL and onto HCMC & Jakarta for over 10 yrs. Very often experienced turbulance over the bay of bengal. One time in a thunder storm the plane actually got hit by lightening and diverted.

[@user-yb1wt2mq8c]

@@michaelhollingworth8905 "One time in a thunder storm the plane actually got hit by lightening and diverted." Most of the time, lightning strikes on airplanes don't matter as the plane is made with that in mind, the current will just travel on the plane's skin and goes "out the back". They may have diverted due to large amount or size of the thunderstorm at or near the destination and thus, unable to land there even if they perform holding pattern to wait it out. Better to land somewhere safe than risk running low/out of fuel at destination.

[@aey808]

Upper altitude winds at the time of the incident were light, less than 30 knots, with no jet stream in the area. The likely cause was an encounter with a thunderstorm. Thunderstorms are common and were present in the area at the time of the incident. The flight can go from smooth to severe turbulence in an instant as the aircraft enters an isolated cumulonimbus. Onboard weather radar can display moisture in thunderstorms but occasionally it won’t display the upper parts of the storm where strong vertical winds are present without moisture.

[@user-yb1wt2mq8c]

"Upper altitude winds at the time of the incident were light, less than 30 knots, with no jet stream in the area. The likely cause was an encounter with a thunderstorm. " If it's thunderstorm, either the weather forecast on route would have indicted or the weather radar on board would have shown. The onboard radar don't just "see" a slice of what is ahead but a column of it, not to mention that the pilots can point it up or down to "see" more of it. With the colours, you kind of "cannot" miss it. If the plane gets into the "upper parts of the storm", they would be in a sudden climb with the air coming up from below, instead of descending. Hot air rises and that is 1 of the 3 ingredients required for thunderstorm. The upper parts of the thunderstorm would likely contain more moisture as well, thus making it clearer for the radar, something like anvil cloud. Due to the temperature, the upper part of the cloud starts to spread.

[@aey808]

@@user-yb1wt2mq8c Most of what you stated is correct. There were active SIGMETS for convective thunderstorms in that area at the time of the incident. There were no active SIGMETS for severe turbulence at the time of the incident. I fly Pacific routes regularly between Hawaii and Australia and occasionally in South East Asia. As a general rule you don’t encounter clear air turbulence in the equatorial regions, strong jet streams don’t exist there. Bottom line…on board weather radar is not perfect. We rely not only on the aircraft’s weather radar but on other sources of information including PIREPS ( weather reports from other pilots ), visual clues ( simply looking out the windshield ) or SIGMETS ( official weather warnings about inflight hazards ). Because there was a death and serious injuries this will be classified as an accident. I will be looking forward to the cause and contributing factors in the final report.

Have you watched the video?? 6,000 feet in about 5 mins [not 3]. The expert is making an educated guess that this was caused by Clear Air Turbulence [aka "CAT"] or maybe an "air pocket".

[@Whitedarkish]

The use of cancer as an analogy for the clear air turbulence seems quite far fetched. Maybe less easily detectable natural disasters like earthquake, where severity and occurrence are unknown can be used instead to paint a better picture.

[@user-yb1wt2mq8c]

It's actually a little easier to detect earthquake, especially around those tectonic plates, "ring of fire", etc. Some have minor tremors in advance [sometimes weeks ahead] and seismic detectors in the area helps. Though I agree that using cancer as an analogy ain't that good. Not enough is understood about clear air turbulence, "CAT". Weather radar, including those onboard aircraft uses moisture to help with detection, which don't really help with CAT.

[@cjayaram3472]

With technology getting improved, how come clear turbulences are not detected to take evasive action? Understand this particular aircraft Boeing 777 300ER over 10 years, could this be the reason for not having tge latest technological updates?

[@user-yb1wt2mq8c]

Currently there are no tech that can detect clear air turbulence or air pockets. The weather radar on board depends on detectable moisture in the air [example clouds], sometimes there are moisture in the air but too low for the radar to pick up, so radar will show it's clear as well. Humans don't fully understand about weather [we are still learning more about it] and how clear air turbulence, "CAT" [or air pocket for that matter] form. Predictable turbulence like near thunderstorm, strong jet stream, large pillar of cloud/s building up, etc are avoided but you can't avoid what you can't "see". Maybe go into the meteorological/weather industry to learn and help come up with a solution to "CAT" or air pocket. 1 thing is for sure, climate change is making these things worst and more frequent.

[@jiageng1997]

[@sieghart7889]

u think a plane is so powerful? mother nature is 1000 times more powerful.

[@user-yb1wt2mq8c]

Read up "Clear Air Turbulence" aka "CAT" as well. It's is sudden and unexpected. In that event, the pilots will set the engine power but that power will NOT be max since you don't want to over speed or over stress the plane as well. As the wind/air direction and strength is unclear and possible to be changing, it may over power the engine momentarily [aka temporary loss of controls, thus severe turbulence]. In theory, even at max power, the plane cannot climb and will continue to descend IF the air is pushing down on the plane and at a strength greater than what the engine can give. You can read up on "Microburst" too [not in this situation but a more simple way of talking about wind direction/strength].
