Mate, for the same reason you need it for your engines and windscreen. Whirling wings of death=lower pressure=slight reduction of temperature (same as at the engine intake)...add visible moisture and, even with slightly plus temperatures, you can get icing. Admittedly its not likely, but thats the way the regs are written for the Seahawk at the moment.
So, what I was really after is what the rules are for OTHER people (ie. you)...care to say? I mean, you're the guy from Norway so I assume you have more flight in icing (or potentially icing) conditions.
