In fairness to the guys on the mic. they are hamstrung to a degree by Aus archaic rules, malevolent noise lobbies and weak as piss pollies. They do however have a responsibility to offer professional advice on how to improve the system. A trip to a few overseas airports would work wonders for the corporate knowledge base. (Chicago, LAX, JFK, Atlanta, Narita, Incheon, Heathrow, and Gatwick to name a few)
As much as I would love a visit like that unless I do it in my own time at my own expense, its not going to happen. Even better would be a 2-3 'exchange' type arrangement. We do have a few 'foreign' controllers, and locals who have come back from working o/s, which is the next best thing I suppose.
Two questions though. What 'Aus archaic rules' are you referring to, and what is, for example Gatwick's arrival rate compared to BN?
