it's clear most pilots are not following the current CASA rules.
That is they are not using the ATC frequency to give circuit calls at non mapped airports.
Do you reckon CASA rules should be complied with. Or doesn't it matter.
And what's wrong with a simpler system if it's safe and if it works ?
And you can still listen to the big ones. Simply monitor the nearest ATC outlet if you want to
Dick, what's clear to me is that few pilots using unmarked strips bother to make a call at all.
Certainly, I never hear them unless they have an organised event in which case they should be asking for a discrete frequency.
There is a significant number of marked airstrips which have 126.7 as their CTAF scattered around the country and I have never heard calls on that frequency from aircraft at unmarked airstrips nearby when over flying. But I have heard pilots transmitting over another because they are both using 126.7 at different locations.
A small aircraft flying without OzRunways is a rarity now and it's an easy job to follow the frequency boundary changes on the electronic chart. Please Do NOT advocate for their removal.
