It's interesting that Airbus advice is to turn off two ADRs, which immediately adds to confusion in the flight deck with only one air data reference available.
Is there any reason why the FACs couldn't be switched off instead to drop the aircraft into alternate law?
Edit: Presumably this only applies to aircraft fitted with a specific type of AoA vane, as we've heard nothing about this for our Airbus fleet.
