In PJ2s example regarding the comment -
One of the comments at the end of the ride was, "too much talking during the ECAM action drills...I want a 'curtain' drawn down between you two so that one flies the airplane and one does the drill".
I see that comment as one which perfectly applies to the three-man flight deck, where the situation ..."that one flies the airplane and one does the drill". was the ops normal in most non-normal situations.
maybe he was from the Golden Era!
And a very good practice it was too!
