caiozink -
Happened to my and several other A330 drivers in my company...not a "close to zero" probability at all !!! ALL speed indicators went to ZERO...no AP / AT / Rudder travel limiter / Alt Law no protections.....turb was light, we came out of the clouds, ice was melted by probe heat....airspeed was recovered, as well as AP / AT.....alternate law remained, as expected (reset possible only on the ground, no hyd press). Beleive me....airplane is VERY tricky / sensitive to fly !!!
If this is indeed the case, I submit some serious modifications need to be made...NOW.
