I use FS Meteo 6.4 (with Weather Display) and FSUIPC 3.202 in FS 2004.
My problem is with wind transitions. Very often the wind changes so quickly that it looks as if I suddenly gave full rudder for a brief moment. This happens with 2-10 minutes intervals, or thereabouts.
Occasionally, the transitions come in very quick succession, about once per second, with what appears to be random values. When that happens the aircraft becomes impossible to control until I kill FS Meteo.
I have set FSUIPC's "Smooth wind changes near aircraft..." parameter to 1 degree per second, but this doesn't seem to have any effect. In FS2002 it always used to work very well.
I have noticed that the FS Meteo flag "Disable Wind Transition" is set and dimmed and that the manual claims that this option is no longer needed with FS2004.
Please advise.
