Hi 737NG,
Yes I know, when one Crew Member calls Go Around we do that and stick to the maneuver with a missed approach followed that bulked landing but the human is still the weakest part in the chain and there is, at least until today, not maintenance programm invented that integrates the human into the closed loop.
Not quite sure what you mean .... but in the old days on TriStars, we could only do CAT IIIB No DH AutoLands in the UK. Everywhere else (e.g. Paris, Frankfurt etc.) we did CAT IIIB with a mini DH of about 15ft. We had to see "One centre line light or marking" in order to continue to AutoLand. There is no way you could do a manual landing from it, due to the absence of the visual clues - so once you'd pressed the TOGA switch at DH - you were going around and would most times kiss the runway with the wheels.
