@HN39:
I'm sure you're correct. However we're talking about a situation whereby all three airspeed sensors (pitot tubes) are being fouled by disturbed air as a result of extreme AoA.
You're also absolutely right that implementing a warning - either visual through ECAM and/or aural - that AoA is no longer valid would be do-able, but it's then incumbent on the crew to understand what that means.
@LW_50:
I'm not disputing what you're saying - but the <60kts limit was not implemented purely for the purpose of avoiding spurious warnings on the ground, it was also because the data from the vanes is unreliable in the air in that scenario. CONF iture is working on the assumption that the airflow from the descent would be enough to generate a valid reading, but I'd need to know what the specification said to know whether that was true or not.
