ACARS Message
1 - The date stamp of the LAV CONT message is from the evening before (2245)
From a pilot prospective and arguably by just looking at the failures on the list:
2- One ADR failure is NOT consistant with flags on PFDs. (airbus eliminates 1 erroneous data source if 2 others are the same, transparently to the pilots)
BUT
Two ADR failures is ! and the ECAM message would read:
3- NAV ADR DISAGREE ! which we find in the list.
4- which in turns get the Airbus to revert to ALT LAW without protections (overspeed, and alpha)
5- autopilots, ATHR, NAV TCAS and F/CTL RUDDER TRVL LIM are associated inop items.
6- F/CTL computers (Prim 1 and SEC 1) could then be reset, and recovered (or not) (they receive wrong data from ADRs)
We're left with the STBY probe, feeding directly (no ADR) the ISIS (self contained stby instrument). Which also seems to report faulty info !!
Near Max rec ceiling, the operational airspeed margin on a jet is quite narrow. easy to go to overspeed, or a stall (no protection), especially in very turbulent conditions.
Flight manually assured using good old techniques of "Pitch and Power", in the QRH for "unreliable airspeed"
7- last message on list : 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 !)
Now we'll have to wait for FDR / CVR recovery ! if ever.
