It's reasonable to presume this is the first incident of this type, as the AoA probes referenced are a new fit item. As such no procedure existed prior (nor was there any need for it)
The issue of corrupted data that can mislead the flight control computers is certainly not new. But a new dimension is reached with Airbus as the protections take over, and so, based on those corrupted data.
No need for a procedure Dozy ? Would you still think that way if you were a pax on that 330 ?
I don't know which crew had to deal with that AoA issue and how they did react but privately, they probably have a lot to say now, not everything being necessarily nice to Airbus ...
Did you say EVA air jc ?
