I believe the sim/check pilot failed 3 ADRs for the exercise...
Recalling the picture of the PFD with the FPV visible, one would assume only 2 ADR's were failed. You would not have an FPV with 3 ADR's failed.
Variable Airspeed Drift malfunction may be a better way to do this than constrained ADR failure. The ECAM messages are ADR disagree ones (like 447) and not ADR fault.
Double ADR fail is indeed ALT2 and good for stall demos with the FPV, but it is not ALT2(B).
...but these are esoteric areas for a non-engineer pilot of these airplanes!
Agreed, but they do fall into the category of nuts and bolts. Hard to keep an old Flight Engineer trained guy like me from pursuing this kind of 'trivia'. Remember the old Burtek Boards?
