SS, if you like to hand fly raw data approaches, then the BA monitored approach is just for you. If you are the non handling pilot, the a/c will be handed to you prior to TOD and you can do what you like to put it in a position from where the other guy can land. Normally he'll call visual and take it from you when he sees the airport. Could be 2,500' on a good day or 210' if the weather is down. If it's a good day, just brief and ask to hold it down to minimums.
If it's your sector, then you should be visual when you take control so no more "raw data". The system works very well on a crap day as it saves you the transition from the panel to the world outside close to DH. It's a daft system that must still be followed when it's CAVOK and the non handler flies the autopilot round to 2,000' or so.
