Why don't you arrange to sit beside an approach controller at one of thes airports to see how it's done? Or is your mind closed?
Just like that huh? Should be easy to get time for that...what with all the excess staff we have around here.
I have previously publicly committed myself to donating $1100 to a program that will send controllers to the US to observe how it is done over there. I am sure Dick Smith would support such a program, as he did when he was on the board of the CAA.
