I haven’t experienced much turbulence in maybe 15 years, whereas I remember in the 90s I experienced tons of turbulence in almost every flight. I am not sure if this is something modern airliners have been designed to deal with or avoid, or not. Has anyone else experienced this or is my memory just faulty?

A smart, independently minded person, would do the following risk analysis: - Planes fly through the atmosphere in varying conditions. - The conditions that lead to uncomfortable or dangerous turbulence are not at all uncommon. - These conditions are unpredictable and have little warning. - Wearing a seatbelt is a very minor inconvenience, and will protect me from the worst of the harms that can come from common turb…

> - These conditions are unpredictable and have little warning Not true at all. The vast vast majority of turbulence incidents are very well predictable. It's not 1930 anymore. > - The conditions that lead to uncomfortable or dangerous turbulence are not at all uncommon. Except your flawed logic in the previous point flows to this point. The question isn't turbulence but unpredictable severe turbulence which is much…

"The vast vast majority of turbulence incidents are very well predictable."

On the large scale, yes, on the scale that causes a plane to drop a meter at very short notice, no they aren't. If they were, I wouldn't have been in planes that dropped a meter without any warning. Your "1 per million flights" is probably based on statistics relating to reported injury (correct me if I'm wrong). Those statistics would be skewed by many factors, not least people wearing seatbelts.

I've flown probably around a few hundred times. I've experienced uncomfortable (spilt drinks, rollercoaster feelings) probably about ten times. I've had actual dangerous turbulence (both times, as you say, with warning) twice. Once into Frankfurt, once into Singapore.

On a couple of flights the turbulence warning from the flight crew has come through after the initial experience of turbulence.

I'm not saying we're not good at detecting it, and I'm not saying it's super common, but your one in a million number is wishful thinking.

By the way, I actually love flying, and I still regard it as an incredibly safe way to travel, but wearing a seatbelt is still a good idea.

> Your kitchen does not have staff telling you to make sure you are wearing a welding mask. The advice to wear your seat belt throughout the flight are hardly clear and emphatic. They often make it sound like something they have to say to cover their asses. There's certainly no clear comms around the risk of death and serious injury. I have no idea in this case whether the indicators went on in time but I obviously w…

Yes, they say it to cover their asses -- for the very very rare occasion when an unbelted passenger ends up stuffed into the overhead lighting panel or carry-on baggage compartments. :) Seat belts in cars also contain several CYA-grade chimes and buzzers. The owner manual may mention risk of injury or death. Likely an airline's contract of carriage contains the same. I suspect both are read as often and as eagerly by…

> [..] in response to your use of ignorance as a defense for ignoring airplane crew instructions.

Unless I come from an alternate universe - most people wear their seatbelt during take-off and landing and when the seatbelt light comes on.

I wear mine through most of the flight but I only started doing this fairly recently because I learned more about turbulence.

I'm not defending ignorance at all. I'm simply describing how poorly the risks are communicated and the reality that most people I've observed don't wear seatbelts for the entire duration of a flight unless the warning light comes on.

Nearly every flight they state that you should keep your seatbelt buckled at all times. If someone decides that they don't need to do that, it is because of their willful ignorance, sorry.

Why do you perceive wearing a seatbelt on a flight and minimising time out of a seat as such a high cost/inconvenience? I hear this line of thought a lot, particularly nowadays around masking to avoid COVID, and I’m always intrigued by this idea that avoiding this tiny act that barely impacts you is somehow sticking a big middle finger up to fear

If humans beings were perfectly rational at all times everywhere then the world would look a lot different (and much less exciting I presume)

If human beings were even marginally rational most of the time it would look a lot different!

It's not "constant fear" to just leave the seatbelt buckled. It literally requires less thought and effort to just leave it buckled, because you'll inevitably be re-buckling it when the plane encounters turbulence or lands. Using PPE is not about living in fear, it's about taking appropriate precautions.

Did you read what OP wrote? It's not mostly about wearing your seatbelt when seated but mostly about never ever ever leaving your seat. That's the constant fear part.

That isn't what I said.

> So it's a bit like "why don't people wear a welding mask while cooking?" Your kitchen does not have staff telling you to make sure you are wearing a welding mask. It may also lack appropriate indicator lamps that tell you when it is a good time to wear your welding mask. It is also not standard practice in all kitchens. It’s actually not like airplane seatbelts at all, where they are ubiquitous and the risks of not…

People are constantly bombarded with seemingly unnecessary warnings. I frequently assume that these warnings are to insulate a company from legal trouble and not really to protect me. This might be an American perspective.

See: many airlines that still warn to put your phones in airplane mode, despite that being known nonsense for decades

I'll be the first to admit that I held conflicting views: For one, I never thought someone could die from turbulence (besides a medical condition such as heart risk). At the same time, I'm sure certain falls/impacts are quite lethal even in very short distances. Yet, i dont understand how turbulence makes a plane fall 6000 ft in 3min, unless the automated (turbulence?) avoidance system engaged and caused the injury i…

> Yet, i dont understand how turbulence makes a plane fall 6000 ft in 3min

That's because it didn't, and armchair experts are breathlessly reporting on a completely normal (if even a bit slow) descent from cruising altitude to a lower altitude as part of their arrival into Bangkok.

> The Associated Press has analysed tracking data captured by FlightRadar24 which showed the Singapore Airlines flight cruising at an altitude of 37,000 ft. Just after 8am GMT, the Boeing 777 suddenly pitched down to 31,000 ft over the span of about three minutes, the data indicates.

2,000 fpm sounds like the pilot changing flight level to evade the turbulence, not the turbulence itself.

It wasn't even turbulence evasion, if you actually look at the flight data it's just the plane coming in to Bangkok (its diversion airport).
