Wing flex during turbulence

[Tabs 2,790]

Normal approach to land includes full deflection of the elevator like that? I'd be interested to hear who your DE was. Someone was playing with (/abusing) the plane, g-loaded the wing, took a funny screenshot, and people are using a corner case as 'evidence' that we screwed up. The elev is clearly at full deflection. Yes, it looks a bit odd fully loaded up like that, but keep in mind that the behavior to cause it (as is clear in this very screenshot) is about as normal as a 744 doing a Blues run at a local airshow.

 

Bingo - there is serious G loading on the wing in that shot.

Sounds like your turbulence settings need to be dialed down a bit.

Thats what i am thinking. thanks for the reply

Guys, I understand that you coded based on feedback from people with the type rating and technical documentation, but that doesn't mean there isn't a problem.

 

I agree the motion is a little exaggerated for any given level of turbulence, but in your screenshot, it's clear from elevator position you were putting the 744 thru some extreme maneuvers.

 

Cheers, Rob.

Welcome.

It was AS2016 turbulence setting causing the problems. I turn them down 50% and now its as I would expect. Thanks

Glad to hear it. You're welcome. If you're interested, there's a notional chart in the Intro Manual that shows some of the crazy g forces weather programs will throw at planes in the sim.

I have AS2016 and actually my turbulence setting was on 70 before and 2 days ago when I've installed the QOTSII and tuned down the turbulence setting to 35 (it was recommended by EZCA 2.0) and the bird still twerking around more than I've ever seen 737/777 before during cruising. Gonna test lowering it a bit more to see if it helps. 

It's not disturbing or anything like that....only so much twerking I havent seen since my days flying PA28 in real life.

Erik,

 

If it matters at all:  I find ASN's turbulence model to be so ridiculous that it almost doesn't even warrant leaving it running.

 

I have mine set to 15...  and it is still a bit too much.

 

The problem is that ASN does not appear to apply any appreciable smoothing or gust control to their injection model, so you can get wind gusts that would sever the wing in real life...  even at very modest settings.

 

I have voiced my opposition to this ridiculousness for years- as it hampers our ability to give you a truly valid flight model.  I think about 1/2 of our development time in the modeling/behaviors arena is spent on "how to we keep the weather engines from exceeding the actual, real world limitations and capabilities of this model?"

 

It is fraught with dangers...  As we can't possible stop all of it.

 

So try 15 and see what you think.  I think you will find it to be far more reasonable.

Thanks for advice, after work I will check it for sure!

I'm happy to report that with the settings tuned doen to 15, it flies without any twerking.

There are 3-4 different "turbulence" settings in ASN.  Are you setting the "Maximum Wind Turbulence" setting to 15 or the "Turbulence Effect Scale" to 15?

I believe it's the Turbulence Effect Scale.

During the beta I decided on the following for AS16 + ASCA.  It works well for me... YMMV.

Is it not possible that there may be a link between this (apparently) exaggerated wing flexing, and the noted "droop" of the outer sections of the wing when on the ground?
