inertial reference (again)

Takata,

I am really getting very confused with all this conflicting information.

In the following message:


0211 34-12-34-0 FLR IR2
EFCS1X,IR1,IR3, ADIRU2 (1FP2)
ADIRU2(1FP2) - ADR2 self monitoring & PHC rejects own data
Loss of discrete data from ADR2 = PITOT 2, STATIC 2L, STATIC 2R, TAT 2, AOA 2.
NAV DISAGREE CONCLUSION DELAYED - ADDITIONAL FAILURES - RECOMMENCE FAULT ISOL
I know you didn't post it... but what do you think is a guess and what is indeed documented ?

How can you get a fault of a inertial reference unit out of conflicting raw air data ? Isn't inertial reference data independent from air data ?

And isn't this fault detected by simple comparison involving INERTIAL DATA only ?

This is a mess...
