Chopjock, some of us on here have flown singles at Night in all sorts of cruddy weather, its not nice. Would I prefer to do it in a twin with a comprehensive AP and nav system to help take the load off me? Oh yes, every time.
Of course you would, so would all of us when someone else is paying for it.
You obviously missed the whole point...which is safer?
(I guess in your heart of hearts it must have been disappointing to discover you're actually a bean counter..)
