Most of the times you DONT do any control inputs at all since you elt the autopilots fly for you.
Did you do this in FS or what?
The Cat III landings in the VC10 were the most relaxing. The a/c flew itself onto the ground with a greater accuracy than could normally be obtained manually. Because i was in the jump seat the crew decided to show off and broke open thier sandwiches . So to say the autolands were a picnic would be absolutely true in these cases!!!
Yes as for myself I have done manual Cat III landings which have been close to the minimums. But, as you say the majority were on autopilot. (of course one does them on the sim but I have to say one doesn't really get the same sense of urgency!!!!!) The important thing is to acquire the top of the glide slope as accurately as possible and frequently this is better achieved manually.
don't even think about manual acquisition unless the conditions are smooth.
