"Hysteresis" x Early warning

So, if possible*, would be useful to have early warning indications of UAS, conditions leading to Stall, etc.

* Technically speaking even the UAS condition seems be detectable "before" the Systems (Pitot scanning, etc.) process it. Freezing, etc. (most events) very probably are not instantaneous and could trigger an Early warning (of this very important parameter to "advanced planes").

Improving "Fault tolerance" and "Graceful Degradation" in order to give the crew "better chances" to timely understand and precisely act, very fast, ASAP.

A sudden law switching together "non reliable indications" clearly is not compatible to the "advanced planes" design philosophy of "Fault tolerance" and "Graceful Degradation".

Not to mention the ABSURD reliance on IDENTICAL (and statistically unreliable) AS sensors. This is not redundancy at all (in most situations).

Clearly IMHO creating instead "highly complex scenarios", even for an "advanced plane" designer.
