I used to always use ASA, but now to try and see what is causing my crashing and loss of textures, I have gone to the default downloaded fs weather. Well guess what? The s-turns are back! the only option is to turn off turbulence effects completely via fsuipc. PMDG blamed ASA and their unrealistic exaggeration of turbulence, but it seems the default weather has the same issue. So how can I get the 747X to fly with turbulence enabled?ThanksAlex

I really am surprised that anyone blamed ASA. The problem is with MSFS itself, the weather engine generates sudden shifts in wind direction/velocity and temperatures and pressures. The only way to tame the beast is with registered copy of FSUIPC. IMHO the turbulence is so poorly modelled I never turn it on, many agree.

But I have FSUIPC making sure all those shifts are not happening... and still get s-turns with light turbulence over mountains

Do you have the barometric pressure smoothing turned on in FSUIPC? Agree with Dan, FS default weather engine is really bad and I don't use it.

No one "blamed ASA" - I remember pretty clearly stating that it's because ASA uses default FSX turbulence that the S turns happen. It's the FSX turbulence modelling that's the problem, not anything specific to ASA.

So is there any way to tune down turbulence a little so the airplane doesn't do s-turns but still have turbulence? Yes George i have it smoothing pressure changes too

My point exactly, the MSFS turbulence is so unrealistic as to be unusable. Believe me, flying in real turbulence is rarely a visual experience unless you are bouncing off the headliner and all the PC sim can do is visual. Reaching for a knob in turbulence can be interesting, how do you do than in a PC?

From what I understand no, a custom turbulence model needs to be created. Vangelis was in contact with HiFi about helping with it at one point...

You can change it in the ASA options menu.

I have it turned down to 5% and still the airplane cannot fly in a straight line

Try opening the fsx.cfg file in the users directory in notepad. Under [Weather] alter the TurbulenceScale to 0.4 or 0.5.It does help a little and if you get the right settings to suit yourself in fscuip for winsshifts and pressure then it'll happen rarely. It won't cure it but at least it'll be rare and will disappear after a bit.I don't think there would be many planes flying if they had to cope with the 2g turbulence or winds that swing around by 180' every few seconds that is in fsx weather lol.If you use ASA turn off the wake turbulence as well... that can flip an airliner...John Ellison

Alex,If you still have ASA installed have a look at the Latest Revisions doc. Should be under start, all programes, HiFi, ASA. It has a section entitled "NOTE: PMDG Aircraft and Potential Turbulence Sensitivity Problems". I found this last night and have made the changes, I still need to run a check flight to see if I still get the turns. You never know, it might just help.

Dan, that's a good point, I guess the closest to that is in a VC, if the plane turns or descends or climbs, then the panel moves vis a vis the mouse pointer. Not the same as trying to push the buttons on a GNS430 with the right hand while holding her upright with the other hand, and bouncing around in your chair, but its in the same ballpark. That said, I enjoy a nice cup of coffee or an adult beverage while flying the 744 through a thunderstorm on the PC. Not possible or legal in the actual air...

Also make sure you have barometric pressure smoothing turned on.
