Media reporting it dropped 6000 feet in "a few minutes".

How much of that is likely to be turbulence v controlled (can't think of a better word) flight to deal with it?
The very worst turbulence might drop an aircraft a couple hundred feet. 6000 feet will be the pilot trying to get away from it by changing altitude.
If you include wake turbulence then the deviations can be thousands of feet in some instances. The A380 vs CL604 a few years back saw a 9000ft loss and the aircraft rolling several times.

But yeah it would seem to be a controlled descent to get them out of the turbulent air. I don’t know why the media have to sensationalise a situation which is already severe enough. 6000ft in a few minutes is a perfectly normal descent rate.

I am a nervous flyer, I'm fine if its smooth, its juts the turbulence I don't like.

I like to think I am relatively intelligent and rational person, HOWEVER as silly as it sounds (and I know it is silly), my fear is that the stress on the wings will force them to break and we will plummet to our death.

As another poster has said, this (for me atleast) is reassuring that my idiotic thinking is exactly that.

My last flight a month ago, i sat next to an aircraft engineer in the RAF and he said they are tested ten-fold more than they will ever encounter in real world conditions. Which I'm sure they are! It doesn't change my anxiety building up this week, for Saturday when I go away next!
You are me! I enjoy take off and landing even though it's the most dangerous bit, and don't mind at all when its bumping around in a crosswind on landing. Even a go around or two hasn't phased me. But turbulence at 30 something thousand feet scares the bezejeezus out of me in the most illogical way and I am absolutely on edge. This story horrifies me yet it's good to know the plane survives! I did read once (assuming true) that a small private jet encountered enough wake turbulence some years ago to put it into a complete 360 degree flip. No casualties (except possible passenger underpants!)

Yeah, wake turbulence can be very dangerous but it's not a natural phenomenon thankfully and can be avoided.

Turbulence getting worse due to climate change, is there anything not caused by climate change? It seems to be the go to for everything

One more question for the pilots? When you do encounter a period of severe turbulence (out of the blue) like CAT. You’ve had nothing untoward on weather radar, or warnings from other pilots ahead

Assuming you are in the cruise Auto Pilot on, obviously buckled in. Does it come as big surprise to you guys? Or does the training and experience just kick in? And simulator training?

What I mean is, are you guys getting thrown about a bit at the pointy end, and can it be a bit disorientating ?

I’m assuming the Auto Pilot clicks off immediately, and you are straight into hand-flying. Do all recovery’s follow a similar pattern as I’m again assuming each one is fairly unique scenario?

I guess whether it’s day or night, and meteorological conditions have a large impact?

Apologies that’s maybe more that one question.

I’ve been out flying my RC plane tonight, wonderful conditions - certainly no turbulence.

Clearly not. The two aircraft cited above were separated as per the rules. Wake turbulence encounters are reasonably common.

Recommendations were made to not have it happen again and when they finally publish the full report I'd expect those recommendations will become rules.

The incident was over 7 years ago and there have been no modifications to standard separation in that time. The application of additional separation against A380’s during the en route phase of flight would be extremely difficult to implement particularly in the climb and descent phases where it’s almost impossible to accurately monitor the profile and separate against.

Again, layman here,

Given the obvious internal "damage" will they inspect the Airframe for any issues or would it be purely procedural "nothing to see here" after a reported event like this.

Always very sad to hear people have lost their lives in such an incident, and any children or adults on the flight probably traumatised as a result as well.

Hi if you do a Google search for something like Pistonheads- Turbulence how serious is it?

You’ll probably find my old thread, the question of wing flex was addressed very well on it. I’m sure it will alleviate your fears.

Edit. Having said that? There were a few horror stories on that thread from other contributors and their experiences of Turbulence. Maybe not look up if you are nervous flyer!


Edited by Jim H on Tuesday 21st May 12:52
I posted my experience on that old thread, which was not dissimilar to the Singapore one - with 9 people carted off in ambulances with broken limbs once we’d landed. Not something I’d wish to repeat but a good incentive to stay strapped in. Luckily I was.

I'm not a commercial pilot but have flown a lot - I'll answer a little until Eric and others can fill the gaps.

Aircraft have radars to show the weather that's ahead, and if needed will deviate their course in order to minimise the turbulence for the passengers on board. In addition the flight crew of planes ahead will report severe turbulence which is then relayed to following aircraft - more often than not this is the trigger for the "fasten seatbelt" sign to come on.

As far as the pilots getting thrown around themselves - they're upfront with 4 point belts (lap and shoulders) - and have almost certainly started in much smaller aircraft (I fly an Ikarus C42 which is bounced around like a tennis ball at times).

I'd imagine the cockpit would have been calmer than the cabin itself with things flying about and people screaming. The reality is the pilots would have known that the plane would 'survive' the turbulence - they just needed to get it back under control. The passengers would have had other feelings.

Extremely rare to happen and condolences to the man who passed away.

Flown three times in the past few days and crew tannoyed repeated requests to wear seatbelts at all times while seated. I always do. I think we will see a regulation change in the not too distant future that requires seatbelts, like in cars, to be worn at all times and there will be a ‘return to seat’ light added for situations currently covered by the ‘fasten seat belts ‘ sign. This could easily be done by replacing the No smoking signs which are hardly needed these days.

Recommendations were made including not flying directly under the centreline and modifying separation but until the final report is published there will be no rule changes. I strongly suspect there will be something though and perhaps that's why it's taking so long.

Anyway, back to the thread topic.

CAT is almost impossible to predict and it is impossible to see ahead the conditions that cause it. Warnings of CAT on a route are usually announced over the radio by a crew who have already encountered it.

We are getting better at plotting jet streams but being precise about the locations of where jet streams might intersect is still pretty hit and miss.

I imagine the cleaning bill for the inside of the aircraft would have been quite something, I can see a lot of people being airsick, and maybe even losing control of their bodily functions? ( I certainly would have done!)

I used to fly a lot and have been in a few flights with terrible turbulence, I don't mind admitting they completely scare me. The worst one was flying back from the middle-east and the 'plane just suddenly dropped and the chap next to me hit his head on the overhead bins. I always wear that seatbelt. Most people look at it and think it is worthless but do not realise where the force is going to come from and it's not forward....

I also tend to look at the stewardesses and see if they looked freaked if they are calm it makes me slightly better (still very unhappy though). I dated a Virgin stewardess and she has done hundreds of flights and hadn't really seen anything that bad. I guess you just have to be unlucky. She complains more about the awful Vivian Westwood uniform,

This would have tipped me over the edge if I was on this flight: https://www.independent.co.uk/news/world/americas/...

Seem to remember the Virgin ones have fixed bar stools and belts.

I think this is coming and maybe pretty soon. In a few years time we will look back and think it was incredible that you didn’t need to wear a belt at all times on a plane.
