So creamy. If we followed the NAS as approved by cabinet the frequency boundaries would not have been put back on the charts.
in this case it would not be possible to comply with the CASA NOTAM as a pilot would not know the " area " frequency to be on.
You conveniently also have ignored the evidence I gave re the serious breakdown of separation between a 747 and another airline because a VFR pilot was giving postion reports on an ATC control frequency.
In the Sydney area on a weekend we have 100's of VFR annoucements being re transmitted on the Sydney approach frequency including parachuting at Wyong and Wollongong and announcements from aircraft at Brooklyn Bridge and other places. At the same time the controllor is giving separation instuctions to Airbus 380's and 747's and the crew of these aircraft are forced to listen to this irrellevent traffic. It's obvious that an Airline pilot from China Southern or other foreign airlines would most likely have no knowledge of where Brooklyn Bridge or Wyong was!
Imagine being an airline pilot flying a wide body into Heathrow or LAX and having VFR aircraft jamming the frequency with Position announcements. It would never happen as their airspace is properly planned .
Creamy. This is all rellevant to the current argument that you do not grasp - CASA advice to give taxiing and circuit calls on frequencys also used to separate airline aircraft will never be sensible - no matter how few calls you can childishly try and prove may or may not happen
