What's the proposed solution? No reporting points? Just call 3 miles from the D anywhere?
Do we think that improves things?
Class D towers work in other parts of the world when you "call 3 miles" inbound. Would it work at Class D metro towers in Australia? More than likely not, so don't call them Class D towers. Call them GAAP and process the traffic accordingly. I'll tell you what doesn't work, inbound reporting points that have been swallowed by suburbia: GMH, Academy, Target, 2RN and the ridiculous Goodna. Try spotting Centenary Bridge unless you've been flying into AF for a couple of years. Still working: Park Ridge (but not for too much longer), TV Towers, Prospect, Carrum, Braaahton (and that can be confused at times).
I can tell you what
IS happening is students (and most unfamiliar pilots) with their head buried in iPads inbound via stupid reporting points.
I did my CPL at Bankstown in the days that Clinton speaks of. It's no bull!!!! that you'd have 3 on final on each of the runways multiplied by 3 recurring. Why are these towers now not capable of handling the traffic they used to? At Bankstown you quite rightly used to get a bollocking if you flew a 747 circuit. You knew what you had to do. The eastern circuit at Moorabbin is a joke! Most of the circuits in these towered aerodromes are a joke.
