Sigh. We've been here before as well.
Sure, some sectors, but not all. Until the question gets asked and researched we don't know. ATC doesn't work very well on "the make it up as we go along approach" - it results in huge amounts of money being needlessly spent. Been there, seen that.
The problem is you get in the ear of whatever politician before any of that has been answered and they set things in motion. Still without having answered those questions.
We don't have any spare console capacity in TAAATS so what happens when it's discovered half way through that we need more consoles? Where's your plan for that contingency? There is none. Not to mention the extra controllers to man the extra consoles.
Building something up from scratch that doesn't have to take a very particular form is an utterly different matter to trying to change a large, mature and very integrated system. Have you successfully managed such a transformation?
