WARNING! WARNING! Incoherence alert!! Yes, Dick, in the airspace that is the highest risk (your words) you have VFR deciding whether or not he's going to be a collsion risk to a RPT High Capacity jet without saying a word to anyone! Incoherence 101!
It beggar's belief that on the one hand you rip into me for wanting to keep DTI in Class G+ and do self-segregation and demanding that we IFR be controlled by ATC to 700ft, and on the other you are quite happy to let VFR swan around without saying anything so close to the airport! The stupid part about it was the tower was there and talking! Who would organise a system where, within 15miles of a major airport, VFR can swan along doing their own thing. It is quite acceptable to play ATC, but both parties MUST be involved. If only one aeroplane knows what's going on, it's NOT Alerted See and Avoid.
Rediculous Madness!
Previously, IIRC, you also made some jibes at the ATSB after Launy shemozzle along the lines "they didn't say anything bad about E". Here's what the report had to say:
While a single occurrence does not provide the basis for a major change to the USbased NAS, which is yet to be fully implemented, the circumstances of this serious incident are indicative of a need for further review and analysis by the responsible authorities in consultation with industry.
and
The ATSB recommends that Airservices Australia, in consultation with the Civil
Aviation Safety Authority and the NAS Implementation Group, review NAS procedures and communications requirements for operations in Class E airspace, with particular emphasis on air transport operations during climb and descent in non-radar airspace, with a view to enhancing situational awareness of pilots operating in that airspace. The review should include examination of, and where necessary revision and updating of, education, training and chart frequency material.
That is why "rollback" occurred, because terminal Class E is fundamentally flawed.
