This is direct from an operator that operates Caravans and other planes for Cargo hauling. Listen to his opinion on the Caravan in regards to flight into known icing.
The Caravan, if treated with the respect will fly very well in icing conditions as long as you know when to quit and get out, like any airplane. Main thing is to follow the limitations and stay above minimum airspeed.
The tail does not have an upload at all. Cessna with regards to the Caravan; does mandate the flaps be extended when below the minimum airspeed in icing to help prevent a wing stall not a tail stall.
I have flown this plane in the worst possible ice and it tells you when it doesn't like the situation so get out and also it does not have a problem flying in the ice as long as you follow the manufactuers recommendations for flight in icing.
