Jim Carter's experience is telling. When a cold-soaked airframe descends
into the clouds it is going to collect a lot of ice in a hurry. Where does

The thin sheet metal skin on the plane warms up fast. It's the fuel in the
tanks that hold the cold. So, obviously, the answer is to make sure you
don't have any fuel left when you start your descent :-)
