BarkingMad,
A classic example of DISTRACTION to all you real prof pilots out there!
The OP referred to a VISUAL APPROACH
Very soon we're into discussions on MDAs etc.
Maybe because the OP then posted subsequently:-
What about the Captain who wants to continue below DH without the required visual references? (Again, this may not even be a remote possibility in the age of SOPs, if so I apologise now!)
In my head it might go something like this?
F/O: "Approaching DH, not visual"
Captain: "Oh, let's just go another 100 feet and see what happens..."
F/O: "Captain, you MUST go around"...... "I have control."
