ADVISORY pertaining to Air cond/pressurisation MODE Fault, seems to be linked to cab descent rate (unable to cope with a high VS descent to maintain required DIFF pressure !)
No point. As demonstrated, wrong air data from ADIRU are enough to trigger the actually transmitted advisory! Why is this a professional forum, when there is only media blurb considered and re-pasted? (Sorry to the guy from whom I took the quote above, does not mean any negative, just an example.)
But please all, read some posts here before re-posting wrong "findings".
What is the point that some posters even dig deeply into actual aircraft manuals and actual system definitions and / or contributing their actual hands-down experience, when their careful thoughts and findings are buried by meanigless chatter from worthless media repetitions?
Yes, could have been a steep descent, as it could have been
anything by now, but you simply
cannot conclude this from the ACARS data. (As well the often cited "TCAS antenna fail" is simply wrong, but posted over and over again.)

"Oh, and IR needs TAS input to keep itself upright.:"
That is of course incorrect. As this is intended to be a professional forum, please either inform yourself ahead of posting nonsense or ask this as a question.
