RetiredF4 asked ...
Would it be logical to assume, that icing took place not only within the pitot-tubes but as well on other critical aircraft parts/ surfaces as Flight-controls?
Would it also be logical, that the heated pitot-tubes would be the last parts being affected by icing due to the heating of those?
I believe that the suggestion is that AF477 was in abnormal icing conditions, where ice would
only build up on heated surfaces. [See references to engine core icing earlier in the thread.]

I'm still struck by the apparent near-simultaneous failure of the pitot-tubes. It might be irrelevant to the eventual outcome, but it seems surprising there wasn't an observable gap between the failures.
