Probably somewhere in the pilot's manual: Not recommended for flight into known icing conditions. Yeah, I see the deicing boots on the wings and tail but all of those antennas look like ice magnets.

Former maintainer of the systems in these birds here. The antennas weren’t a problem for icing. Too little surface area for most, and the larger ones had de-icing boots on them.
