Lyman,
Your version of "leaving no stone unturned" is commendable, and I'm not in the business of being patronizing.
However, this debate around what was said and what was seen by the pilots, is the very reason that the BEA wants mandatory recording of RHS parameters along with a "look" at what these guys should have been seeing. No doubt the BEA are confused by the actions taken and the words spoken when the recorded FDR LHS data shows something else.
Trying to recreate what was actually on the RHS PFD is fraught with danger.
- It can be assumed the same was available on the LHS PFD, but
- Was the PNF on the same page?
- Neither of the pilots referred to any discrepancies between PFDs, and
- The PNF was aware (at times) of what the PF was doing and commented when required.
Should data have subsequently been recovered from the QAR, I believe we would have heard through some 'leaky pipe' by now.
I am also unable to understand why the PF was able to look at an overly blue PFD and not accept that he was in fact "attempting a climb to the stars".
So, there you are. Was the RHS PFD overly blue??
