One of the 24 ACARS messages sent by the airplane was EFCS PROBE 1+2/2+3/1+3 specifying so that all probes was in default.
Can you show the source of that statement. That wasn't on the original list of messages that I have?
There was EFCS1 and EFCS2. Not unusual considering what came before.
Given the two ADIRU and the ISIS failure are the pilots left then with no attitude information whatsoever Or did they have attitude but no speed?
Please remember that ISIS and ADIRU have attitude info and airspeed info. The two systems are nearly separate.
The airspeed info was at fault. There is no evidence yet of attitude indication problems.
