"@Cool Guys - As Hunter says, the PFD speed tape is blanked out with a big red X over it when UAS is detected, and ECAM shows that there has been an air data fault. The system *does* tell the pilots what has gone wrong."

Nope. You are not wrong, but you are creating the wrong impression. You claim it took several seconds for the computer to determine UAS. DETERMINE being the operant. The pilot is privy to the result of the computation, not its inception.

Who cares if B or AB both do it or do it wrong. There is a reason to consider the current practice can use some updating. A red X on the tape? What a clumsy and open ended cue is that? If only a short span, the pilots, BOTH of them, should know instantly the speeds are being reviewed for failure. All three speeds should be displayed to both pilots, separately, for a concurrency that ennables CRM, not isolates each.
