CPC
PJ2;
HN39 has already asked the question regarding valid ADR info to the CPCs. In the circumstances surrounding the various ACARS messages, e.g. NAV ADR DISAGREE, and it appears that at least PRIM 1 and PRIM 2 were switched off, possibly in an attempt to reset. Do you believe that in the probable circumstances at 0214, that the CPCs were receiving valid ADIRU data?
I'm thinking that in the fail safe situation that the pressure relief valves, once triggered could possibly be configured to also initiate the Cabin Vertical Speed Advisory. Any thoughts?
