Of course its a 'layer of cheese' just because something is briefed doesn't prevent it from being a threat. Anything that is non standard is a treat, this day and age a visual approach isn't a standard approach. I am not saying that they shouldn't be able to do it just that it i not the norm and is a threat. Especially so if your tired, and in training.
