Ok Pete, understood. I was only confused by whether you meant the "eliminate FLT loading difference" as a separate step from those you listed, but I get what you meant to say now. Get well soon.

Pete, What exactly do you mean by eliminating the FLT loading difference? How? Is the "0E90 as type U16 and 0E92 as type U16" that I should add the ones you meant with this or do you mean I should add the same wind to the startup flight as in the test flight? (Btw please note that in the test flight theres only cloud turbulence not wind turbulence) I will do the tests again but dont have time to do it tonight, I'll try to do it tomorrow though.

Oh, and just to add something, in the 4.284 log file, the problem starts almost immediately after loading the turbulence test flight. Both tests have severe turbulence, but in 4.26 it does not make the plane go to extreme banks beyond 30 degrees and the autopilot still has some control over the heading of the plane.

Pete, I've sent you new log files.

Pete, I have sent you the log file while the problem is occuring. Hope it helps.

Pete, Sorry for the late post, I was a bit busy early this week. I have tested with 4.284 now, and as much as I'd love to say its working fine, its not. Even in moderate turbulence the plane suddenly tips and banks steeply all the way to 90 degrees and comes crashing down. I checked and double checked that I have the right version installed. What on earth could it be... Its behaving just like before 4.26. 4.26 seems to be the only version that works perfectly.

Thank you very much Pete for investigating. From my memory I can tell that at least the version number shown in FSUIPC user interface was indeed 4.28. As you mentioned, I also remember a similar problem in verions before 4.26. I really have no idea what could have went wrong. At least when I installed I asked the setup to "just look for existing registration", but that shouldnt have anything to do with the installation process itself, right? I will try the version 4.282 then, when it becomes available and report back here. It will probably have to wait until tomorrow night though, but I will post here as soon as I have tested it.

That's all very well, but you'll be stuck on that version forever, despite any new facilities and fixes, unless we can sort out why 4.28 doesn't appear to work. And I am not going to support old versions, ever. Best to stick to the latest and temporarily turn off the cloud turbulence, as I said. Pete Well, I meant as a temporary solution ;) When the problem is solved, then of course will go permanently to the latest version.

Why not simply turn off cloud turbulence for the time being? Pete Or go back to 4.26. In my tests yesterday, this really seemed to work for me. I had no problems with that version.

Small update: I re-installed 4.26 and have been testing with the same scenario and so far I have not had any problems. Even in severe turbulence the plane keeps its course and does not bank more than 10 degrees. It starts to seem like there really was something in the 4.28 that, if not to others, but to me at least caused some strange behavior in the PMDG aircraft.

Okay. Thank you Pete.

Hmm. In that case it sounds like the wind smoothing isn't working either, then, because the only reason I added turbulence emulation was to generate turbulence to replace the smoothed out air which smoothing produced. Seems that somehow what you've got is the reverse of everything I strove for between Christmas and April, spending many hundreds of hours, to achieve something like success. I really can't understand what has happened -- nor why it seems to be only happening to you, and four weeks after the last FSUIPC change? weird. Pete Pete, I only changed to version 4.28 recently. I had other things to do so I missed the exact day it was released. I'm also puzzled and it seems like nothing is making sense. The wind smoothing IS working perfectly all the time no matter what is going on with the turbulence. I am sending you the files and the PMDG panel state (the panel state file needs to be copied to the PMDG panel state directory) of a situation where the cloud turbulence is causing that problem for me. I am praying you would have the same situation so you could see whats happening.

I can tell theres turbulence because the plane is still wobbling around just like in normal turbulence, and the airspeed is variating rapidly just like in turbulence, so I'm 100% sure there is turbulence. An update of the testing is that the "supress wind turbulence" did not remove this turbulence. Seems like the FSUIPC is not doing anything to the wind turbulenc. It just smooths the wind, but the turbulence is like its coming from FSX weather engine!

What I mean by that is when you SHIFT + Z key the FSX displays its wind values. In wind turbulence, the values were not changing, not even a bit, but in cloud turbulence both the speed and direction were shifting/varying. I guess thats the strange thing here. It seems that the wind turbulence does add turbulence, but doesnt variate the wind, making it possible to stay on course with the PMDG plane. Hoever, when the cloud turbulence does indeed variate the wind, the problems start.

What values did you try? I adjusted the Turbulence rate values. I tried lowering to 2.5,0.5 Did you try adding that parameter to the INI file as I suggested? Yes I have added that parameter. Regards Pete
