I'm getting on occasion what appears to be a water vapor spray on the ground and behind the airplane. In the air it turns into a smoke effect about 200' below the airplane.Is this just me, or is there a known fix?Thanks.zach

It's one of those FSXisms, MS turns on the effects but often the effects keep on going. Not very 'as real as it gets.'

Was just about to ask about this myself, search and you shall find right :wink:From the answer already provided I take it not much can be done about this "feature", too bad since it looks very unrealistic indeed! I'm a little bit puzzled though when you say this is caused by FSX because I can't recall I've seen it when flying other a/c like the MD-11 for instance or the 747 for that matter but also some other a/c from other vendors.I wonder if there maybe is some way you could disable this effect manually by renaming the effect file the J41 uses?

I noticed it about a year or so ago in the 744. As Dan said, it's an effect that doesn't seem to have an off switch. You will often see it when you depart from a wet airstrip. I don't know if it just becomes locked after a long time running or what, but that's my guess. Prior to PMDG aircraft I didn't do many long taxi's and pretty much always set "Active runway", so perhaps it gets locked or corrupt after a certain amount of time or additional conditions. The reason I say this is because I cannot duplicate it just by starting on the active and wet runway, at least not 100% of the time.

OK, not much to do about it then I guess...too bad.

Search for "effects_package_1.2.zip" in AVSIM library, AS ALWAYS backup your originals. After replacing the FSX default water spray i have never seen it trailing the aircraft in the air again. As an added bonus these textures are more realistic and much nicer looking than the default one.
