Meikleour - No offence intended and thank you for your detailed response. As you can see I'm not a frequent visitor to the site & have been rather busy lately. I have also been mulling your answer over to get my head around it and come up with an 'intelligent' response (struggling with that!).
In my experience every approach ends up in speed mode (with athr engaged), it's part of our landing checklist. I see your point about the pseudo G/S compared to the actual ILS G/S. The FD's could be following a slightly incorrect vertical profile if in v/s or fpa so you wouldn't want to be distracted by the FD's even if visual. There is always a natural tendency to follow them. I also wonder if the go around has any part to play? On some aircraft there is no SRS engagement below MDA during NPA's, so you wouldn't want to be following the FD's in that instance. I just wish the manuals gave more clear explanations of 'why' things are done in a certain way and what would happen if you left the FD's on until touchdown?
Thanks again
