I think the key phrase here is "automatic approach"....To my old grey haired head, doesn't a Cat II take you to 100' and then you either take over manually or "go around"?
I have a lawyer but won't need her here...this shouldn't be an "Airbus" thing...It should be a "crew" thing...
Fly enough Cat II's successfully in the sim and you simply aren't mentally prepared to do anything other than land....
However, on the Boeing....
