I still need to know the details of 2CE2, and 22FN-10FC... (the part coding convention does give clues, but not much)
I find it interesting that Pitot 1 PHC came up, but ADR2 data downstream of the PHC2, failed.
How did you get to the relationship between air & phc data and the IR2 fault reported by disagreement with IR1 and IR3 ?
I think Inertial Data is independent from air data - and that the opposite is not true - so an IR fault would only be detected by comparison with inertial data...
Am I Wrong ?
P.S.: I know AOA differs from pitch attitude - it relates to the relatively motion of the airflow to the wing - but is there any inertial component in the AOA calculation ? This question is related to the qantas incident...
