Had some time to do a bunch of flights with Build 640 now in different areas with different weather.DWC ON, force dest ON, vis altitude set to 12000ft, registered FSUIPC with wind smoothing and turb inhibit ON, FSX with med-high settings, WinXP, dual core intel, nvidia7800...nothing has changed except the version, I keep all options the same.- through climb and descent, wind shifts quite sharply causing some yaw motions, settles down at cruise.- clouds appear then vanish moments later through climb and descent...until at cruise then things settle down. ASE has always been this way, just seems to be worse / more frequent in 640.- on approach, wind shifts through the descent quite sharply, most noticeable from ~7000 to touchdown...the final 2-3000 feet AGL is a bit of a roller coaster. This too seems to be worse in 640 than with earlier versions.- visibility graduation does not seem to be gradual at all...after takeoff to cruise, visibility seems to all over the place with the haze layer appearing and vanishing seemingly at random,- constant light turbulence at cruise has been a problem since ASE v1...I suspect this is related to the constant haze layer depicted in FSX even though haze layer is disabled in ASE...turbulence is associated with cloud, haze at altitude could be getting confused with cloud. It's like ASE is producing a haze/cloud layer around the aircraft to simulate the MAX visibility setting (89nm in my case in ASE), FSX picks up on this and injects turbulence...is my guess.I have suspected for some time, many of the issues reported here and from others appear to be a battle in progress between FSUIPC and ASE and FSX...which one is in control at any given time seems to be a battle of the giants...hopefully there will be a clear winner when the dust settles.Rob.

I could be wrong, but I don't think you would want to have those particular FSUIPC options checkmarked at the same time that ASE's "new" DWC mode is enabled. The result would be that BOTH programs (ASE and FSUIPC)would be trying to smooth winds and visibilities at the same time, which would understandably lead to all manner of strange behavior in the injected weather, as the two programs would be "fighting" each other.I use DWC with FSUIPC weather-control options turned "off" and winds, clouds and visibilities are very stable on my system.Jim Barrett

Hi JR....you may well be right...I use DWC ON and wind smoothing in FSUIPC going back to the initial release of ASE where the only way I could get the S turns to go away was to have both DWC and FSUIPC wind smoothing enabled. This set up was also confirmed to resolve S turns by some other users I communicated with (BobbyJo, *******, and a couple others) outside of this forum, so I have stuck with that as it works for me...I never see S turns to this day. I do still get wind shifts during climb and descent which I see from other posts here is an issue being worked on.You have raised my curiosity though, I will test a couple flights with wind smoothing in FSUPIC turned off. FSUIPC is also supressing turbulence...I have a working theory there are really 2 layers of turbulence potentially surrounding the aircraft at any given time, ASE controls one of them, the other is suppressed by FSUIPC. This is something 'BobbyJo' and/or '*******' (I can't remember which) had come up with and the theory seems to be correct. Now if I could only get rid of the constant light turb at CRZ AlT, which I suspect is related to the haze layer constantly depicted in FSX that ASE attempts to control but does not seem to be doing so as intended.I will give it a try with just DWC and report back.Thanks,Rob.PS - I dug up the post from another forum (LDS767) where Bojote/******* speaks directly to having both FSUIPC wnd smoothing and DWC turned ON...from the LDS forum...Bojote posted back in May of this year...==============================================...However, DWC does NOT seem to 'smooth' winds correctly, in fact.. it simply DOES not based on MY particular experience.The latest version of FSUIPC did change the wind smoothing algorithm (you can read about this in the PDF docs for FSUIPC)I was able to completely eliminate the 'S-Turns' by a combination of settings, namely:1) DWC Enabled in ASE2) Wind Smooth Control ENABLED in FSUIPC3) Supress Turbulence (in FSUIPC)Aditionally, I have ASE with SP1 installed and FSUIPC March 3 2010 version.My theory is that there IS a problem (conflict) with Thermal Layers/Turbulence AROUND the aircraft, as if there were TWO conflicting sets of info. by supressing FSUIPC Turbulence you remove ONE of the sources of this wrong DATA, so you STILL experience turbulence, but not causing problems.***...and posted later also by Bojote in a reply to me back in May...***Wind SPD/DIR smothing I think is set to the FSUIPC defaults, no values out of the ordinary there. and no, cloud and wind TURB are NOT supressed in FSUIPC.. the only thing I surpress is TURBULENCE.In fact, my FSUIPC weather settings are REALLY simple.. I simply click on Weather Defaults (which sets all Weather values to their defaults) and then I proceed to:1) SUPRESS TURBULENCE2) SMOOTH WINDS (simply check the little box)3) Smooth temp and varo (defaults values as well)I don't change ANYTHING else in the FSUIPC weather settings :)And I have NEVER experienced a problem with the destination weather.. ever! Its probably because I'm using DWC or because I lock the destination weather (there is an option to do so in ASE) I also have the Dynamic rate of change set to 0% both in ASE and FSX. This 'rate of change' affects how the weather changes between ASE updates, and personally I don't like the idea of FSX 'changing' this weather, I rather have ASE do it every 15 minutes because who knows what logic FSX applies to 'update' or dynamically change this weather in between those 15 minutes :)Rob, I fly DAILY and I can assure that for the last 30 days, I have not seen a SINGLE glitch with ASE. Probably the only one i saw, was the wind going in circles, like if there was a tornado around my A/C but it happened in a VERY gusty day in KJFK and just once.=========================================Any input from ASE / Jim on this issue as it stands to date would be appreciated, the post is from May 2010...things may have changed...which is why I am going to try FSUIPC wind smoothing OFF and see if the old S turns problem returns.

I've been using B640, in standard mode, since its been available and I find the wx to be quite accurate from start to finish. I'm also controlling wind smoothing through FSUIPC. I was having a problem with "losing" the wx along my route but that was because I had mistakenly set the suppression altitude above my cruise altitude. The only "annoyance" I find is the periodic "sky flashing" when the ASE updates the wx, but I can live with that as long as the wx, being depicted, is accurate.
