Sadoko:
Is it credible one can hear ice coming out Pitots bouncing on cockpit? ("Dans le cockpit, s'ajoute le bruit de la glace se détachant des sondes.": ~ In the cockpit, you have to add the noise of the ice coming apart from Pitots)?
As one who spends his life creating sound simulations for all classes of aircraft (at the highest fidelity Level D for commercial aircraft and equivalently for military sims), I find it almost impossible to believe that anyone could believe such ice shedding would be audible - the location of the pitot tubes themselves and, above all else, the small quantity of ice involved (due to the physical size of the tube) makes this claim extremely unlikely.
As it stands, for the many simulators I have been involved in, ice shedding from propellers, with the ice being flung from the blades and hitting the cabin sides, is about the only sound cue related to icing that I believe
might be audible to any cockpit crew.
Given the altitude, true airspeed and the factors mentioned above, I do not believe that ice leaving the pitot tubes would cause any noticeable audible cue for the crew AT ALL.
