Hello Daniel,
this doesn't sound like a problem of the A330 but of the scenery.
Which scenery have you loaded for Zurich (is it the FreeZ scenery? If yes, be careful when using it together with the Swiss 2004 sceneries, I also get these problems in Zurich).
My question would be, do you get this issue in other airports as well? Can you try a random airport where you know you have no sceneries installed?
In my FreeZ scenery I get problems with the A340 for example when the other planes are working OK (never tried the A330 though).
Once you establish whether it is a scenery or an aircraft problem, write back.
Cheers,
Sotiris
