BTW I know it' semantics but the term has definitely been "Monitored Approaches" in BA Longhaul for quite a while now, I believe "Split Approach" was once a shorthaul term, which probably explains Hobo's comments........
'Split Approach' was never a BA shorthaul term, to my certain knowledge, at least up until the very late 90's. It was a term used by the flat Earth brigade referred to earlier....(ok, mea culpa for feeding the troll).
The term 'monitored approach' had two connotations, at least in the early days, ie the approach was monitored, and it was also 'the monitored approach to flying' ie the rational division of duties compared to the then Boeing standard 'one man band'.
