Hi everyone, I have been flying plenty of long hauls in the past month and a half with the PMDG MD11 and ASA, and I'm happy to report on my system I have ZERO s-turn issues, even with FSX turbulence ON! I am hoping that the latest FSUIPC working in conjunction with the latest and greatest ASA (build 586) has solved this issue once and for all. I have done quite a few north atlantic crossings between America/Canada and Europe and I wanted to share my settings with others with the hope that they can get similar results.I do not use DWC, but I have FSUIPC handle wind/temp/baro pressure smoothing. I researched these forums to come up with the settings I use, including the Hifi addendum supplied with the updates. FSUIPC is beta version 4624 (obtained from the forum on Peter Dowson's website)1. Open FSUIPC.ini to make following updates: FSUIPC (if installed and FSUIPC wind smoothing/turbulence effects are enabled) - Edit These FSUIPC.ini settings:TurbulenceRate=0.5,2.5TurbulenceDivisor=40,40,80,802. Open FSX.cfg and make following change: FSX - Edit the following FSX.cfg setting (under [Weather]):TurbulenceScale=0.500000 3. See screenshots below for my settings:

Hi All,The OP does mean ASE through this thread!!

OMG, I really feel like a clutz, I took all that time carefully preparing this thread and forgot that one important fact. ASE it is, not ASA.But, I have some bad news to report......no sooner had I put this post up that I arrived after a transatlantic flight between Cologne Bonn Germany and Philadelphia Intl, on final approach over the NJ shoreline I got what appears to be the dreaded S-Turn!!!!!!!!I must have been lucky up until now, but it appears I hit turbulence between 12000 and 7000 ft. The wind direction was constant, but the speeds was oscillating between 20-30kts, and the PMDG MD11 made some minor turns to correct itself. The duration of this activity was about 5 minutes, and it eventually settled down. Autopilot was on LNAV, and the turns were slow. She didn't turn out of bounds or fall from the sky, and I figured I should slow down from 250 to 220 kts. Looking back, even if it was an S-turn, I should have put her on heading select until the activity subsided. I really can't be sure if this was turbulence related, or a bad metar data from the reporting station ASE was using. My only other time with an S-Turns was in the PMDG 747 on climb over Germany, and those were more noticeable. And when that happened, I recall the wind direction and speed were both oscillating, whereas this time it was just the wind speed.Anyhow, I'm debating on if I should shutdown turbulence in FSX and FSUIPC...I found some other settings at the following link that I may try also (albeit they are from February of this year) http://forums.flightsimlabs.com/index.php?/topic/1947-asa-ase-settings-with-fsuipc-and-fsx/I suppose if you are very risk averse, it may not be a bad idea to turn off turbulence for the PMDG birds as of now I am not confident that as I was that the S-turn bug is gone.

hi,i have currently tested your ASE and FSUIPC settings with my MD-11  in FSX on my flight KBOS-LOWW.With this settings i was unable to approach my first step-climb level [FL330]. I had s- turns and massive overspeeds and lowspeed stall-protections.So i enabled "disable wind alofts" and "DWC  and smoothing" again and set the max. wind turbulence to 30. This in combination with "your" FSUIPC settings does make normal flying in awkward areas like US East-Coast possible again.regards 

Yeah, after that scare over NJ, I figure the S-turn issue is still going to be around, it will just require workarounds. If you happen to be around and see it happening, switch from LNAV to heading mode to keep the plane laterally steady. I believe the FSUIPC settings I list are fine, but you should also change the fsx.cfg turbulence scale from 0.500000 to 0.300000, per the link I provided above. To make things more confusing, I've started using the new SP2 beta build 625, which may things worse or better on my system. So I've applied the settings I listed to the new "standard settings" depiction mode in the beta, and I'm hoping for the best. For now, I've left turbulence on in FSUIPC and FSX so I can test to see how things go.
