"The ADR fault detection consequent to the blocked pitot tubes. If there's an air data fault, AP and A/THR are automatically disconnected."
Nomenclature. The ADR(s) were not faulty. That is a mistake made by someone who cannot separate a sensor from a computation.
Pedantic? NO WAY. The level of stress can be directly related to an assessment of what is wrong. If the pilots think the computers are faulty, that is different than an iced pitot probe.
This aircraft takes things for granted that are serious, and in this case, may have allowed the pilots to believe the flight computer was duff, not Ice in the probes. It also prevents the pilots from being aware instantly of a possible problem with these speeds. They are too unimportant to know something may be wrong with airspeeds? Do we not want to frighten them?
Is it possible for pilots to make a mistake by thinking something is more seriously wrong than the reality? I would say, yes. If, on top of that, there was a delay, sufficient to cement some confIrmation bias, in the awareness of bad speeds, is it possibly too late to correct this mistake in assessment?
Possible...
"tres turbelences, n'estce pas?" the ride was bumpy, it may be the pilot is even entertaining loss of the autopilot. When it does go, he is sure that is the case.
So now he must hand fly, a challenge...
"No worries, we remain in Normal Law, and have protection. What is with the
Roll? VERY turbulent, then." "Aah, we are protected in PITCH, at least"
