I'm using REX Weather Engine with FSUIPC registered version and already checked the option "smooth wind change near aircraft" (or something like that, and all numbers are default by FSUIPC) but still when the wind change, my aircraft's nose shakes (turn) heavily to left or right and the speed+altitude jumping up and down :( And usually put me in overspeed situation or speed drop dramatically . But then it sorted out slowly and fly nicely.....until the next time the wind change.Btw,sometimes when I'm on final about 50 feet from ground the wind suddenly changes and my aircraft was pushed up which made me go around . This happened several times :unsure:So..my problems are normal or I'm still missing some steps here? :(/Is REX Weather Engine ok for real weather or there is a better program? Today the wind almost made me go around but I still try to land and the plane flare over half of the runway :wacko:Thanks!

I don't know about REX ,but with ASKy in the settings option there is one for wake turbulence (when landing the aircraft in front of you creates turbulence ,and you fly through it. I know with ASKy I had to disable this option , as I experienced some very severe problems with handling on approach.AnywaysIts worth checking your REX options.Maybe another REX user can chip in and advise you.cheers Andy

Thanks about the tip However there were no aircraft ahead of me nor near me at that time so I don't really think this is because the turbulence,actually only from now on that I know there is a turbulence effect in Fs2004

Yes, but what are your numbers? I am using ActiveSky (Evolution), and these are my wind settings in FSUIPC, they work fine:

My numbers are default. If it not like yours I'll try your numbers :DThanks.

@DieselTen: thanks a lot. I have set my FSUIPC page to the same as your (only different the taxi wind) and currently cruising without problems like before And from your picture I found out I left the add random turbulence on. Maybe that is the cause why my plane got pushed up when landing

That is called wind shear. It is always in the back of a pilot's mind esp. on approach. Unless you want calm weather all the time, you will get wind shear. When you move into 'decreasing' wind, it is very dangerous. There are some major accidents you can find out that occurred because of wind shear. Daniel

Thanks for the information :( yeah I've found some accidents related to this issue,from some videos at youtube maybe the MD-11 Fedex crashed at Narita has to do something with this right?

I had the same issue with wake turbulence and also disabled it. It was way too severe to be realistic. Not saying wake turbulence can't be severe and certainly it can cause loss of control, but there are a lot of different parameters involved in determining the severity of it and also ways you can avoid encountering it - but this option seemed to be "all or nothing." Pity, as any little enhancement that reproduces a real-world challenge is a great thing.As for the discussion below on wind shear, I wish that also could be realistically simulated but I have not found that to be so yet in FS9 even using Active Sky and registered FSUIPC.

Thanks for that. As a non-pilot I had no way of knowing whether we could get a realistic simulation of windsheer in FS9.

Look up what wind shear means.You should buy some basic flight manuals (for student pilots) if you love this hobby.You will notice a drop in airspeed quite quickly and then your altitude will drop. If increasing wind shear you will have the opposite.Also I think a L10-11 in the US on Air Crash Investigation experienced a microburst. Still wind shear. There are heaps of incidents.If wind shear isn't a part of your simulation then crosswind landings and takeoffs shouldn't be either.Daniel

You welcome. I'm glad I could help.

Not really worth arguing about but a microburst and wind shear aren't the same thing, though they can have the same catastropic results. And the reason I underlined "realistic" in my post is because FS9 does not and probably cannot "realistically" simulate wind shear. I've been using it since before (that's not a typo) its public release and have yet to experience a realistic wind shear event, even though I have tried to set it up to do so. To simulate wind shear realistically would require control of multiple wind layer effects close to the ground that even with FSUIPC are just not possible.And I have no idea what you mean by equating crosswind landings and takeoffs with wind shear? Other than the fact that they both involve wind and flight safety, I don't see the connection? Just curious

REX!!What is it? I thought it was a scenery/textures type of package.Does it have its own weather engine like Activesky? or would the original poster actually be using FS9s own real weather? If the latter then that would explain exactly why he is getting these wild wind and speed changes ,as this is a well documented bug with FS9 s own real weather downloads.I occasionally used to use it(Real Weather) because its one advantage over ASKy if i was pressed for time, it was quick to download and run if i needed to get flying quickly. however those terrible wind/and speed changes meant such a horrible flight experience I now no longer use it at all.If you really want to end any problems with wind (apart from reducing your baked beans intake)is to use Aktivesky (I am talking 6.5 in my case) but i would imagine the latest version also eliminates this problem to.I also only have the freeware version of FSUIPC as well.PS Other weather programs are available.(I think) Andy A cuppa icon!excellent !Is that a new one?

DanielYou clearly misunderstood my post. So let me help you out. The sentence 'As a non-pilot I had no way of knowing whether we could get a realistic simulation of windsheer in FS9' means that as I am not a real pilot (and therefore have no real life experience of flying aircraft) I am not aware of whether any form of simulated windsheer in FS9 is realistic in comparison to real life conditions. It does not in any way suggest that I do not know what windsheer is. Quite simple English really.Your comment 'If wind shear isn't a part of your simulation then crosswind landings and takeoffs shouldn't be either.' based on what I wrote in my post is rude and insulting. An apology would be appreciated.I wonder though if I'm not just troll feeding.
