Quoting 777fan (Reply 1): I've read this on other threads but haven't flown the A340 series to make a claim for myself. How/why would this be possible?!
I am , by no means an aviation expert . However , I have read on a commercial pilot's blog or web page , that the Boeing 777 just has firmer -stronger or stiffer wings than its counterpart . He said he prefers piloting the 777 for that reason .

On the contrary,I think that the 747 Classics tend to be smooth during turbulences.
In 1995, I had an AWFUL flight on an AF A340-300, and now, I always try to avoid the A343.However, I would like to try the A346 (I would like to fly LH A346) on condition that it rides better than the A343 during turbulences

I've had some very bumpy rides in turbulence on both a Swissair A330 and a Qatar A330 - but nothing really notable when I've flown the 747 (Classic) and nothing on a Sri Lankan Airlines A340-300
The A300-600 can be quite bad in turbulence as can most airbus aircraft. But even recently, sitting in row 1 of a BMI A320 from LPA-EMA, we had some pretty rough turbulence for about 45 minutes, we couldn't go any higher to avoid it though due to heavy traffic flow on the route.
On the other hand, a ride on the 757-300 was very smooth in a short patch of turbulence we had on a flight from STR-SSH.

All these differing opinions show one thing, I think, and that is that unless you ride two different planes through the same patch of turbulence, it's really hard to be objective in deciding whether any one make/model is worse or better than any other.
The worst turbulence I've experienced was in a VS A343 from HKG to LHR, but I have no idea what that same turbulence would have felt like in a 346, or a 744, or an MD-11. It may have been just as bad. I've also had horribly bumpy flights in 773s, A320s and 757s. Having said that, some of the smoothest flights I've taken have also been in A343s.
It seems odd to say that a rough turbulence experience in an A343 was because of the aeroplane, on the basis that other flights in 777s were smoother. Surely the simplest explanation would be that the turbulence wasn't so severe on the smoother flight?!

I agree. Its like judging a car suspension by driving one car on asphalt and another on gravel. How do you compare??!?
Also, the stiffness of the wing is an odd thing. Wouldn't you think that a "more flexible" wing will dampen the smaller vibrations.
Off course, speed has got something to do with these things also. And where you sit on the plane, for example B747 is known to make very low-frequency oscillations during cruise, that can only be felt at the back.

What is the point of this thread?
There were not/are not/will not be 2 identical instances of turbulence for anyone to make any meaningful comparisons. How do you know if this bumpiness is due to a bigger turbulence in the air or the aircraft reacting differently? There is no way you can measure the magnitude of turbulence up in the air.

I've flown twice on a A346 to South Africa, and was seated both times in the back of the plane and still slept like a baby. On the other hand I flew a couple of times over the Atlantic in AF's 773 and it felt much more uncomfortable, once in the back it was not possible to sleep as the aircraft was shaking extremely hard horizontally.
So from my humble experience, the T7 feels much worse in flight than the A346...

Quoting GVWOW (Reply 13): The most turbulent flight I've been on was a BA 747-300, but I've always found McDonnell Douglas aircrafts more turbulent than Airbus.
I've flown a lot of flights on 737s, 757s, DC-9's/MD-80s, and A320's from the midwest to the west coast. There can pretty much consistently be expected to be turbulance over the Rockies, and what I've found is this:
The A319/A320 is probably the most comfortable of the 4 to fly on in smooth air, since it is quiet, and serene to fly in. Crossing the rockies though, it seems to get tossed around more. The MD-80s likewise are pretty easily tossed about. In my opinion, the 737-800s i've flown on are the best through the bad weather. The 757s are decent, but not great in chop, and in my opinion, can be fairly loud.
In terms of widebodies, I've always had smooth flights in the 763ER's across the pond, despite their modest size. I have to say the 744 has a definite feeling of isolation when you're flying in it. Even when it's bad, it's not as harsh feeling.
But that's just my seat of the pants feeling. My flight in an A333 was smooth as well, so I have no bad opinions there.
I would assume an A343 and A346, sharing much of the same wing design, would be similar, though it would go to reason an A346's additional weight would serve to dampen lighter chop.

I have a question not totally related to turbulence.On a recent flight to z from MEXon a MExicana a319 I suddenly became aware of a very gentle oscillation of the plane along the longitudinal axis.I only noticed it because I was looking out at the horizon.I have flown quite a bit over the years and can honestly say I have never seen this before.Can someone please explain this to me .

Quoting TUSflyer (Reply 14): Isn't this topic completely subjective? Everyone has different tolerances to turbulence. While I may think a flight is smooth, the person sitting next to me is gripping the seat for dear life....
I fly for business at least twice a week and firmly believe that you become desensitized to any issues in flight versus someone that flys once or twice a year.
I was about to say this. Added to fact that the same turbulent air wouldn't be present on all flights. The 777 may give a smoother ride that the 346 but it just happened that on this day the 777 rider went through some extremly turbulent air, but his return flight on the 346 the turbulent air wasn't that bad. We can't truly deduce tha the 346 is the better flying plane.

That's right, I experienced the same with a Finnair A320. It was not very fun, I think, worse than turbulences. But no idea about what it is.

This is an extremely subjective topic, but for what it's worth, I've always noticed on 747 classics a slight 'wagging' side-to-side when seated in the rear section (where I travel the most) in anything from light turbulence and up. I've noticed this on 747s many times between several aircraft, different carriers and lots of flights. Not much to do on long haul sometimes I guess...
Generally, I find Airbus a/c to ride slightly smoother (although sometimes it will depend where I'm sitting) than in a Boeing. I believe this is due to the Boeing airfoil sections and wings being more suited to higher mach numbers and having a generally 'stiffer' wing construction. Having said that, it wouldn't deter me from travelling in any particular aircraft, apart from the triple 7. The 777 seems to have a horrible ride in turbulence - but I've only flown in one maybe a dozen times on long haul and it was hard to pin down - I just find it an very unpleasant aircraft for comfort in whatever configuration.
I've flown in A340s through the tropics many times and actually like the way they handle the rougher air at altitude, it's sort of a gentler sensation and usually sends me to sleep.

I can tell you without a doubt what the worst aircraft is in turbelance. The Saab 340......
The general concenus i believe is that the 777 rides well in turbulence, but everyone has their own opinions on that. The bulk of my turbelance experience being on narrowbodies, I have to say the A320 is bad in hard chop, whereas the 737NG's tend not to feel so jarring. I've always thought that while the 757s never felt like they got tossed around as violently, they did seem to be very easily bumped. 757s over the rockies are bumpy, whereas A320s can be very calm, and then hit an ugly patch and be pretty scary.

And in my opinion, closely followed by the ERJ-145. I never get ill on planes, but came close in November 2000 on a COEX ERJ-145 (IAH-HRL) flying through the usual Texas late fall soup.
Also had a wicked run in similar weather in a TWA 717 (STL-AUS) in March 2001.
As to whether this is a subjective thread (asphalt versus gravel), of course it is.
However, I also believe this thread is not pointless.
There are categories of turbulence reporting based upon observed effects (extreme, etc.), much like the Beaufort Scale for wind. Sure, our physical conditions (i.e. inner ear) and tolerances may play into our reports, but given enough data from many other observers in same conditions and aircraft, we can identify trends and tendencies.

I suspect that the A346 might actually be slightly worse due to the greater airframe flexing, being at one end or the other could be quite uncomfotable.
On another point I can't really see how anyone short of professional pilots can comment on one aircrafts ability to handle turbulence over another. They are all pretty good these days.

I think that the best way to judge which is smoother during turbulence is to ask pilots who have flown both. I don think you will find that many! And to top that, the pilot must have flown each aircraft in similar turbulent conditions. I say fat chance.. but possible. In all cases, ive flown the 330, 340, 777, and 747 many times over the atlantic, and i havnt noticed much difference, simply because 95% of my flights did not have any heavy turbulent parts. So i dont think we are in the position of deciding. Just my opinion.
