So far the latest info in FMC's thread re AF's release of the 'AIRMAN' ACARS fault info is the most pertinant info avail and this is what we should be looking at.
What sequence of events could cause a Prim Computer to fail causing the AP in cmd to disconnect followed by the other faults 1 minute later is what we need to be looking at. Especially the loss of the Primary flt info provided by the ADRIRU's? And how could this effect the pressn when the packs would still be operating in pneumatic mode if there were a multi elect bus loss with control of the outflow valves still avail in 28 vdc mode....
Lets stick with what we know..
