If there is a design area that needs assessment it is the way the aircraft can rapidly induce cognitive overload. It may be that the lack of discussion on the flight deck was caused by verbal channel overload. To go back to the start of my post: try holding a conversation with someone while carefully reading something different.
Well said.
Back then when flying i would tell my WSO to shut up. Today with my wife continously talking on the right seat in the car (we drive here on the left one) i better donīt tell her to shut up. But lately we missed an highway exit.....
