B737 And Turbulence

Sat Feb 23, 2008 7:30 am

I'm a dispatcher for NW and when looking at the pireps for turbulence it seems that the 737's always are calling it worse than the other types of aircraft. For example a 737 reports moderate or severe turbulence and our A320/319 and 757's report light. Does anyone know if the wings on the 737 are any "stiffer" that makes it more likely to get turbulence?

I flew CPT-JNB last night on a 738 and coming into JNB we hit some bumpy stuff that really shook it about. I'm not sure about stiffer wings but those big winglets really emphasise the wing flex in turbulence.
After Monday and Tuesday even the calendar says WTF...

I don't know if it is 737 specific or the fact that there are so many 737s out there flying. OTOH, I seem to have been flying with a whole lot more FO's who haven't experienced what "real" turbulence is and claim "moderate chop" or "light turbulence" when we've barely entered "very light chop" (if that).

Were these B737s qouted equipped with Winglets?

All AA 738's have winglets so my recent personal experiences have all been on winglet equipped 738s. IMHO, there is no noticable difference in the quality of the ride between winglet and non-winglet 738s -there are very slight performance differences noticable, but no ride quality differences.

This would be from the Pax cabin or from the Flight deck.

From the other end of the microphone/ACARS, I can concur with both your observations...  Wink

I have to agree that the 737 family seems to be a bunch of rough-riding birds. While the conventional wisdom ascribes ride characteristics to wing loading, wing flex seems to play a big part. The 707 and 727 series aircraft had a great deal of wing flex that seemed lacking from my very first 737 ride on WN in the 1970s.

In particular, the 707 wing dampened chop long before it got to the passenger cabin. You could see the wingtip bobbing up and down, the outboard engine nodding slightly less, the inboard barely moving and feel no motion at all in your seat.

The 737, in comparison, rode like roller skating across a washboard.

I too find the 737 series sometimes to be a rough ride in chop, but mainly the 800 series.

The 747-400 is also a bumpy ride during turbulence, more so than any aircraft I have ever flown on - you really feel every jolt.

I could be way off base here - but having had a HUGE amount of expereince being a passenger on 737s (3/4/7/8) I found it to be no more turbulent than other types of similar size - except cross wind turbulence - that big tail plane does catch the cross winds quite well, even at cruise  Smile

I always experienced the 747 and 738 as quite stable in turbluence. The smaller 737s seem stiffer and therefore less pleasant in bumpy air. The 747 is massive and it really takes a lot for it to be moved around in a noticeable way. However, I feel like both the larget 737 variants and the 747 feel substantial and stable in the air...

On the other hand... i feel like the A320 feels rather light and is easily blown about in the wind. When I recently took off from ORD in an A320 and there was lots of low-level wind....wow... I felt a little sick from all of the movement. It just felt like we were getting tossed about and the planes responses seemed lagging.
