In certain situations yes definitely esp in the North Atlantic as described in my original post. While this isn't observed all that frequently it happens often enough that it can ruin a long haul flight unless you are a particularly obsessive FS fanatic and remain continuously fixed to you PC for many hours.Bruceb

Jim,To answer your question, yes FSUIPC does account for wind speed shift and wind direction shifts as well. I for one have been speaking about the two synonymously. A wind shift is a wind shift is a wind shift is a wind shift and they are all bad :) It is an all around wind smoothing functionality in FSUIPC though. According to Jim from ASV the wind smoothing feature is included in the free version of FSUIPC so I do not see what the issue is... Even if it is not. Remember, ASV is a weather generating program and that is exactly what it does. It is not a fix for the mistakes that FS made with the entire weather processing engine in FS so why expect them to fix Microsoft's problems? Why work wind smoothing into each and every weather generation program out there when FSUIPC has been tested to do that for a very long time now and it also addresses the same issue with the default weather. The issue is there whether you buy ASV or not so why have the fix in ASV? I kind of see the logic of it if it is a global problem within FS then having an independent fix such as FSUIPC makes sense. Why would independant weather generation programs write a fix that already exists and is readily available (if it really is in the free version like Jim said)Remember FSUIPC was the original fix for this problem and to my knowledge is the only fix. I mean think about it guys, Pete fixed the issue that Microsoft couldn't. I for one am EXTREMELY appreciative of FSUIPC and truly see the value in everything else the program does but to each his own...-Paul-P

Excuse me Paul but perhaps i'm mistaken your one of the guys that asked about the TAT issue on this forum and at PMDG forum and had a thread there mentioning that active sky will add a "force average enroute temps" option? Therefore if that can be added why can't the formula or dll or whatever it is be added to the ASV interface to give us smoothing wind or speed or both.Above that why can you ask for it, and a simmer like me cant. Possibly because you already registered fsuipc so you are in favor of it since you already paid for it, i would do the same.With all do respect as I've always read your posts here and at other forums and have found them quite informative, I'm not bashing here but I just feel if there is a forum I can ask for this option as I don't see a difference between smoothing temperature or winds being that different, after all they are all weather elements.Maybe this wouldn't even fix my issue over the mid atlantic and I'm going a head of myself thinking it would fix it but i know when those winds shifted, they shifted really fast and changed speed drastically making a sophisticated plane change its fuel consumption and performance which throws all that planning out the window. I'm all ears!!!

Hi Bruce,Can you throw me a route where you have seen these shifts?Hope this helps,JimActiveSky Sales and Supporthttp://www.hifisim.com/images/asv_dev_team.jpg http://www.hifisim.com/images/asv_proud_supporter.jpg

Hi Joe,Can you throw me a route where you see these shifts?If average wind smoothing was possible we would have done that 2 years ago, but winds data and temperature data are handled in 2 different ways.Hope this helps,JimActiveSky Sales and Supporthttp://www.hifisim.com/images/asv_dev_team.jpg http://www.hifisim.com/images/asv_proud_supporter.jpg

Hey Joe,No worries at all. I am really sorry if it came across like that, I wasn't saying you didn't have the right to ask for it at all. Of course you do. I am a New Yorker, if you don't know me I can come across a bit ...hard, cold, ####-like mean or jerky sometimes but under it all I am a nice guy :) Again, apologies if it came across like that. I did post in the PMDg forum about TAT but unfortunately, TAT does not appear to be an FS thing but an ASV thing with the virtual stations, hence ASV producing the fix. I was just saying I can understand why the wind fix is in FSUIPC and not ASV. FSUIPC was out first, the wind problem was with the default weather so Pete fixed it first. Why fix it again and apparently beyond that, it is not that simple to fix. I have no insight into that side of it and how hard it would be to program, I am just a dumb end user too.I was just giving my .02 on the whole fsuipc thing and paying for it :). Is the wind smoothing not in the unregistered version of FSUIPC? For me FSUIPC is worth it for the controller calibration alone. I just got the throttle quad today and would never have been able to set it all up without FSUIPC. Again, no worries and apologies again if I came across the wrong way, I really hope you get this resolved because I remember how tough it was to fly with those shifts sometimes.Good luck,-PaulJim, as for a route, do KEWR-EGCC, KEWR-EGLL, KEWR-EHAM any Atlantic crossing should do it... I program them in FSBuild and use the winds aloft data for planning.

Paul,Thank you for correcting my incorrect information. After your post, I did what I should have done before I posted and had a closer look at FSUIPC. And, indeed, it does smooth shifts in both wind direction and wind speed.I'll now bow out of this thread and let those who know what's what continue on. :-)Best regards,...jim

Hi Jim i'll specify the route when it happens again i should be doing a return flight soon and may encounter the shifts, if I do i'll gladly give you all the info.

To Paul, thanks for understanding, and I re read your post and I may have taken it out of context and misunderstood so i'm sorry too!Happy landings!!!

Here it is:KJFKMARTNTOPPSYAYHECKK5350N5540N5730N5720NBILTOMIMKUMORAGEGLLMy original post has the metar so you may be able to recreate this. The problem seemed to occur in the early stages of the trans oceanic crossing. Bruceb

Hi all,To avoid any confusion, please realize that ASV uses FSUIPC wind smoothing facilities (registered or unregistered) to provide the default 5 kts/deg per second max change. This is sufficient smoothing for most applications.Some users with very sensitive aircraft flight models have reported that even 5deg/kts per second is too much for their aircraft to handle. Some users prefer greater than 5kts/deg per second. Unfortunately we do not have the facility to change the wind smoothing interval limits - this must be done through FSUIPC user configuration and is only available in the registered version.Hope that clears a few things up!If anyone is experiencing greater than 5 kts/deg per second change, verified by SHIFT-Z, please let us know and also contact Pete Dowson on his forum @ www.schiratti.com/dowson.html as this indicates a failure in the FSUIPC wind smoothing - unrelated to ASV. We haven't had a report of this in many months.. there is a possibility that the new FSUIPC revisions (released last week) are causing problems in this department?Best,

Hi Damian / guys,I'll just throw in my 2c I think it's limited prity much to the atlantic crossings... I had a 280/25 to 355/98 wind shift just today over the atlantic... I'm running FSUIPC 3.48 and don't expierence this much at all normally.

Well as an update to my earlier posts, when I experienced these drastic windshifts on an Atlantic crossing (in my brand new PMDG 747)the movement was many tens of degrees within a few seconds. Then I had the same thing happen over the UK mainland just before commencing a descent into EGLL. The aircraft was able to recover but at some cost to fuel consumption and certainly not very realistic. This was a saved flight and I was able to replicate the windshifts when running the flight again over the next half hour or so (thus using the same or very similar weather each time).Bruceb
