General theory indicates that the thinner is the aerofoil, the more likely it is to pick up ice. As the tailplane is definately a thinner aerofoil than the wing, it should, in accordance with the theory, pick up a larger load of ice. This was certainly so on the Jetstream 31, which was a delightful aircraft until it picked up ice, whereupon it bacame a total bitch. The Propellers, being the thinnest aerofoils of all, are the most ice-prone part of the aircraft.
