Midnight,
Raised again, because CASA has got it wrong!! To the potential detriment of air safety outcomes.
The CASA attitude is that they are the only soldier in the battalion marching in step.
If we go back before all the recent sodding around with CAR 166, the policy intent (backed by an ICAO compliant safety case) was to keep low level local traffic off ATC (by whatever name) frequencies.
It was never the policy intent that traffic on uncharted strips should use the overlaying ATC frequency.
As to "charting" all the uncharted strips, this is a practical impossibility, even without consideration of map cycles etc.
Tootle pip!!
