I'm examining the fault message at 02:13:14:
"- .1/FLR/FR0906010211 34123406IR2 1,EFCS1X,IR1,IR3,,,,ADIRU2 (1FP2),HARD"
this fault is "timestamped" at 2:11 - was received (or transmited) at 2:13
Maybe it was triggered at 2:10 and received by the CMC at 2:11.
I suppose it means that only IR2 is "faulty"... But it wasn't followed by a message like 'NAV IR2 FAULT'.
What puzzles me is that almost at the same time - or a short time before - a fault relating to ADR1 not being recognized by PRIM2 - only - was also triggered
quite a concidence - or not.
