Whilst it is an interesting article to some degree of which there are many composed the same most of it means nothing. To compare or even think we are part of the aircraft like the nuts and bolts is ludicrous! You can make a 100 A320's identical right down to the colour of the toilet flushing button doing the same task across every single airframe every time but you will NEVER make two pilots the same despite all the hairy fairy HF, CRM and NTS rubbish! It's a fact of life, the human element in flying a plane is variable at All times & cannot be effectively controlled!

machtuk, I think you’ve missed the point of this article. It would appear that fatigue laws are attempting to place pilots into a mechanical category where we are a perfectly predictable and precise instrument with an equally precise threshold for fatigue. On the eve of a very watery CAO48.1, I would suggest we are due for some interesting expectations.
