I'm 100% with Dick Smith on this.
The only part of flying that ever worries me is the 4 minutes when I am in the vicinity of 2RN or prospect in and out of bankstown - it is lunacy to be funneled into a piece of sky at exactly the same height as an unknown number of other aircraft of differing speeds and configurations. Note the emphasis on "unknown". Why can we not give a call on either twr or syd frequency when "approaching 2rn/prospect" to give a fair chance of sequencing into the funnel?
