So notwithstanding electronics, every sector in AC needs 2 controllers and an assistant?
So no sectors (forget the electronics were talking about controlling here) in AC could run with one controller yet in TC they all can and often do, (or maybe have one controller sharing a coordinator with 2 or 3 other controllers).
I'm not getting into a willy waving contest, all I'm saying is that electronics have necessitated an increase in manpower resources. Unfortunately it looks like TC might be going down the same backward path (certainly backward for TC).
