Agreed, sir - my point is just that we do have another plausible potential reason, and so I don't think we can say the AoA vanes (specifically #1) were
definitely affected by ice.
I'm interested - other than the Perpignan incident (where the AoA sensors had been "abused" outside their specs before the flight), is ice affecting AoA sensors as much of a problem as pitot icing?
