Hi,
After Captain entered crew told:
"We tried everything". (indeed not true: didn't try stall recover
)
And could tell (to Cpt):
We had a "temporary UAS".
Why Captain didn't was better briefed?
Many reasons, we may understand.
One important reason:
Crew (it seems) didn't realize they had a (not important) UAS
Crew (likely) didn't know they had a TEMPORARY UAS. (Anomaly
completely disappeared) at 02:11:07)
Perhaps (due UAS known consequences on related indicators, etc.) they created a model of something much more serious: An (unknown) System failure.
HF study may clarify. Anyway, crew could be better helped (by the System). It seems System aggravated the "obsolete Pitot trigger". And contributed to an ACCELERATED DEGRADATION. Perhaps even "misleading the crew" due a design IMHO could (should) be improved.
