Porch Cat 11 training is not much use if you are not auth below Cat 1 ( your post 212). A regulator's approval process needs the airline to make a safety case for AWO operations. Hard to argue its not safer to land Cat11/111 than to divert with a low fuel state to a regional alternate, turn the jet yourself then fly back to destination thus increasing duty time. I am sure you would agree with that but your airline needs to ask the question before a Senate Inquiry does.
And yes well aware ADL is only Cat 1 which is why I referred to MEL...perhaps SN isn't though?
