Airservices have setup areas, such as Taree to Port Macquarie, on a common frequency making these wide area CTAFs.
They are not CTAF plus a low level area frequency.
Also, none of these type of areas have combined uncontrolled and controlled airspace.
What you have suggested could be done but I am suggesting it would create even more congestion, misunderstandings and missed information.
"Once the radio traffic levels get high even more information is missed." Agreed to a point. What is worse, nil to minimal communication (as we have now) or the risk of congestion leading to the occasional "say again"?
- have a look at the volume of transmissions at Bankstown and Camden alone.
It is not 'the occasional "say again"'
"Also trainee pilots quickly get overloaded and miss things like right hand circuits at YSHL". Please expand????
This is already an intermittent problem at ShellHarbour.
Now increase the YSHL radio traffic by 2000% (not an exaggeration).
