Any controller, any sector? Haven't heard that one yet but then my work has always been ADI/APS. I've read bits and pieces about SESAR but it hasn't really filtered down the entire business yet, I'm sure it will though at some stage. It's a bit like saying any pilot, any aircraft. Sure the principles are the same and for 99% of the time you'll be flying along quite happily - snag is when the proverbial hits the fan, you have a human so far behind what's happening that it may well prove unrecoverable.
Unfortunately I refer back to what I stated earlier, if someone knows what they want as an end result then simply write the risk assessment to suit. That way it all looks good on paper. It's not that long ago when I was coming through training. all students were told under pain of death that they were never to vector on the ATM, regulator would strip their license and all hell would break loose. Fast forward a few years and let's do RITT. Thats not enough, now its lets have one controller doing several airports. Where does it all stop? Do we need a major or catastrophic incident to show that sometimes efficiency and cost cutting has limits? I hope not. Unfortunately my experience in recent years has been ideas and plans coming down from senior management to middle management, the mantra isn't "will this work?", rather "make this work if you want your performance bonus and career progression."
