Thanks gbnf, a very interesting exposition of a pivotal time in all-weather ops!
BelArgUsa, in Air Europe we used to do 4 autolands a day if we were on a 'double Paris' or similar. Can't remember the actual wx of course, but we had Cat IIIA (50/250) on our 737-300 and -400 and I seem to recall needing it several times during the foggy season.
Now after 13 years on the B744, like you I have done but a few autolands for real. I agree that Cat II was probably enough on most of those occasions.
