Thank you again for a thoughtful and careful response. The scenario described was intended to be AF447 specific, ie. impending loss of all ADRs. Once you have a double ADR fault, autopilot and autothrottles drop out. With ADR disagreement, you have ALT 2 flight control laws which also means loss of Alpha Prot. in this case. When 3 PRIMs drop out, which appears to have happend in AF447, you have Direct Law. The 30 knot suggested hidden airspeed dropoff would have been just the beginning. The cavalry charge alarm would announce the remainder.
What ECAM procedure would have priority on the display in this situation? Logically UAS should be, but are their exceptions in the logic?
Thanks and best wishes,
