One result of that gave us CTA steps AO85 at 30 miles. What's wrong with that? Nothing really, just that many times every day of the year, RPT jets have to apply power, waste fuel, and often cause the approach to be above profile, because they are held to AO90 until 30 miles.
Growahead,
Having grown a head, how about putting some facts in said head.
Every jet I have flown, 9000 at 30 track miles to run would be on or below profile.
Any pilot who didn't account for such a step in his aircraft handling, so that power application was not needed to pass 9000 @ 30 is taking money under false pretenses.
As for the rest of your posts, maybe you are an example of what is wrong with ATC in Australia, and a complete inability to believe that it is done far better in a number of countries, of which US is one.
By far better, I mean better separation assurance standards combined with more efficient traffic handling.
Tootle pip!!
