The crew never should be "presented" (specially at critical moments) with System "outputs" that they are not capable to understand very fast.
The crews, "Redundant Systems, operators" always must "have chances" to
"keep flying" their increasingly complex, and not perfect (never will be), machines.
It seems, is time now for a very serious effort (a/c designers and operators) for "better interfaces" between crew and the advanced planes Systems.
And i´m not speaking of just training. Complex R&D is required to simplify crew task in dealing with "non routine" situations.
What we have today is not we designers understand by "Fault tolerance" and Graceful degradation" in respect to System behavior, etc. being presented to the crew.

PS: And Airbus SAS share of responsibility in dealing with this effort
is an opportunity for the company that introduced the commercial "advanced planes" (FBW+a new philosophy)
