"Hey, Gums, your pitot system is FUBAR!"
Actually a temporarily and brief data inconsistency between 3 redundant probes made the overall System (A/C+crew) FUBAR.
Just a crew issue or a critical System? And how to improve the original design?
IMHO through an immediate and clear information (not just in ECAM) on UAS onset. And you decide what to do after a precise (assisted by System) assessment.
The AS probes and ADR after the brief "cold" operated again
perfectly. It was a single occurrence of an intermittent failure well documented earlier...
