True. But I think the point is that all this will create is an added level of undue pressure, causing stress levels to be increased which will in turn increase the likelihood of mistakes being made, missed calls etc etc. They will then turn round and condem you on the back of this.
You're right at any stage, day or night we should be able to go into a sim and fly any procedure, deal with any emergency and have a successful outcome. With zero prep. This scenario doesn't mirror that and they are very very wrong if they think it does.
If someone was to go and sit next to a receptionist and tell her that "today if you make a singal spelling mistake in any of your typing, you're fired. And I'm going to sit here and watch everything you type." What's going to happen? They'll make a spelling mistake in the first sentence they write. Does this prove they are incompetent and totally unsuitable? No. It demonstrates a perfectly normal human psychological reaction to being put under that level of scrutiny without notice. A 'startle effect' of sorts if you will.
Once again they have an opportunity for change, to make things better and again it would seem they're going to f this up too.
