Just as the wing is the most critical issue with icing in an airplane it's
the same for a helicopter.

The rotor is the wing of a helicopter and it would have anti-icing equipment
similar to the anti-icing on an airplane prop. Additionally there is
electrical anti-icing on critical areas of the airframe.

As far as I know the only helicopter currently certified in the US for
flight into known icing is the Super Puma, but several others are configured
with anti-icing equipment.

I'm familiar with de-icing on fixed wing aircraft, but how common is it
on helicopters and how does it work? For instance the Coast Guard
flies the Jayhawk and Dauphin and I'm sure these must be certified for
flight into known icing conditions.

Thanks,
