Anza. I make it clear that it is AsA that is not training controllors to provide a terminal service.
007. Yes. If I was in a position of influence that's what I'd do- fly a few controllors to North America to see how en route controllors provide multiple class E approach separation services.
I personally prefer the North American system than our " do it yourself system" in most terminal IFR approach airspace.. Why have controllors if they don't provide an approach service at busy non tower IFR airports but provide a full service right across the country in en route airspace where the experts say collision risk is lower?
