I suggest you speak someday to anyone who has worked in the TCU at Ottawa, Montreal, or Toronto,
about Hub and Spoke.
I PERSONALLY know of three people, one who works
at YOW in the tower, one who is a controlller below
ground at Pearson, currently handling traffic from YYZ
into Ottawa, and a third who JUST HAPPENS to be a very close relative of mine, who IMPLEMENTED several
proceedures, for flights in and out of the Ottawa airspace, and so happened to have been Unit Chief at
Ottawa for over 30 years.
I THINK you will be surprised at what they say!!!
Until you have worked in an ATC facility, and fully
understand what HUB and Spoke is, then don't make
baseless opinions without basis of fact..PERIOD!!!!
