Interesting. So are those A380 and A330 wings just able to cope with ice accretion or do they have some other way of stopping the ice from building up too much?
Not sure abt that. It seems that the design of the wing prevents the formation of ice. Interesting thing is that on a A330 that has just landed after a long flight, ice up to a quarter of an inch thick could be found on the underside of the wing close to the fuselage.
The 747 is fitted with wing leading edge de-ice
The proper term is anti-ice. De-ice is used to describe devices that destroy ice formed on the wing surface like pneumatic boots.
