Doze. Birgenair is the red herring, as it is re: CRM, not Yoke/SS.
CONFiture has it down, and for me, it cannot be seen another way.
If memory serves, AF F/Os are not permitted to fly from a seat from which they do not ordinarily stick. If true, and I am not at all sure it is, this brings up yet another brick in the CRM outhouse. It also, if true, makes the A330 (functionally) a single position, single pilot aircraft, w/o a declaration of emergency twixt the pilots?
IF PNF could only drive the machine from LHS after emergency switch, yet another reason to support his apparent unwillingness to acquire command?
It seems clear, at least, that it may have kept him from taking over, along with the other obstacles he faced.
What say you?
One cannot roundly condemn either the pilots or the a/c alone. I will admit, after all this time, that some serious pilotage issues present.
