I would think that normal procedure would be for CPT to fly AHRS1 to his PFD and FO would fly AHRS2 to his PFD, however looking at the text of the discussion between the two crew members, the FO doesn't seem to be aware of the problem with the CPT display. Does anyone else get the feeling that they were both on the same (failed) AHRS? Other than a previous failure of one AHRS, why would both crewmembers be using the same AHRS? Switchology?
Will the FDR record info from both PFD's and the standby info or only the captains/flying pilot?
As I recall from AF447, there was a problem with only the Cpt data being recorded, and they could only infer what the RH indications probably were. Likely the same on the CRJ.
