I've flown the 737-400 both ways - Boeing style with AirUK (Leisure) and now with BA. I prefer the BA way - why ? Because on a good day you get some handling on every sector if you want it, and both of you are 100% involved in the sector (no room for man and boy). On a bad day (down to minima of any kind) nothing changes in terms of role. When going into a grotty eastern european airfield at night it is a real luxury to be able to peer out into the murk (with an occassional look in) and then take the aircraft having aquired good visual reference.
Very few people in BA dislike our SOP's, so let us get on with it - if you dont like them, dont join! As for Boeing's opinion, whilst I value it, they are a MANUFACTURER, not an airline, and not a regulator. (The CAA dont seem to mind BA stylie ops either)
Hope the above helps.
Best Regards
