When flying an approach in very low visibility, does it have to be performed automatically? or are you as a pilot able to fly it yourself on instruments?
If the landing is fully automated, do you still have to see the runway at the last moment to confirm it is safe to land?
Also, assuming you cannot see more than a quarter/half of the runway, are you relying on ATC to confirm the runway is clear? on a clear day, is it a combination of you and ATC that take responsibility for the runway being clear?
I flew back from the caribbean some years back on a 767-300 into dense fog at EGKK, pilot told us the landing was fully automatic, I think he made a point of telling us because it was unbelievably smooth, and the fog was such that no-one knew we were about to land until the reversers were engaged and we were on terra-firma !
