HiI am using Active Sky Advanced when flying the JS41 within FSX. It appears the icing light illuminates and ice starts building up on the wing leading edges as soon at the temperature drops below 10 deg even in clear air conditions i.e. not flying through clouds. I don't know if this is a ASA problem bit you shuld not get icing in clear air ??Glen Coyne

What icing settings do you have in ASA?Andrew

Hi AndrewNot sure what other icing settings there are but in cloud options Min cloud icing = zero and Max cloud icing = 100% which I think is default.Just noticed the typing error at the end of my first message - sorry about that !Glen
