Complete madness I would reckon. Can anyone advise which section of CASA has come up with this requirement?
Is it an individual at CASA who drove it or was it someone from the industry?
If they want to return to "radio arranged separation " as operated before the AMATS changes in the early 90's they need to employ the FSO's again and bring back separate FIS and ATC airspace and frequencies again. Nothing $30 to $100 m a year wouldn't cover .
Of course they will need to put IFR and VFR at the same Quadrantral levels again and abolish that crazy ICAO semi circular rule that puts IFR and VFR at separate cruising levels!
