Background: I've bashed around in military jets and the likes of the 747 and the 777 for over 15 k hours and never, ever had pitot icing - so what gives with the A330, is it really that fragile
It is not known if similar events (simultaneous multiple pitot icing) ever happened on other than recent Airbus types. These incidents are not always reported by operators but perhaps someone started compiling statistics after june 2009. Yet the probes used by other manufacturers cannot be so different and were designed under the same certification requirements.
Could it be that this problem has more to do with the way they are installed than with the probes themselves (e.g. typical position on the fuselage)?
