Missing ACARS explanations

Hi All!

This thread has been most interesting to me. Especially on points where the opinions among "experts" differ.
I am still surprised by the fact that BEA gave no hints in the short list explaning where the various ACARS were coming from. One of the last was about faults in Prim 1 and Sec 1, which were earlier assumed to be either showing serious faults of caused by pilot shut-downs of these systems.
Very often it has been assumed in this thread that there was 5 computers involved on AF447, however each of the three ADIRUs also contain at least one each and perhaps also one in each of the Air Data Modules. I am making this conclusion from the australian report about sporadic AoA signals, where it is stated a software update for the ADIRU uncovered an old bug.
I am also thinking about a fixation of the pilots on a single phenomenon as part of the causes, somewhat similar to TMI-II operators failed behaviour.
