Interesting reading. Class E without surveillance doesn't appear to rate very highly.

Ambidji recommends that, provided electronic surveillance is established to the surface, Class D CTRs become Class E airspace down to 700ft above aerodrome elevation outside the Tower hours of operation.

No E without surveillance....concur

In print! Most aussie Class D meet the criteria for US Class C! Der, well we told ya so!

Get with the program, Sled/Dick/Joker/Frank and the other NAStronauts! !

The provision of Class E airspace down to 700 feet would necessitate substantial changes to the
Brisbane and Melbourne ATC Centres, with staffing, facilities, restructuring of airspace,
re-configuration of radar displays, and re-configuration of radio frequencies amongst the many
issues to be addressed.

And golly gee willakers Dick, it's not just a simple drop in ATC solution!

I encourage all to have a think about the changes proposed for most controlled regional airports. Change to Class C airspace until a 6nm, A025 Class D control zone will remove a lot of the flexibility that both IFR and VFR benefit from.

At the moment, in conditions where the bigger aircraft want instrument approaches, we can maintain a good acceptance rate with the VFR's with the Class D procedures. If this becomes class C, the possibility for delays to both categories increases. Alternatively, the VFR's get pushed low, OCTA, in close proximity to each other and the CTR boundary. This could increase the risk of airprox and VCA's.

Certainly not saying that we cannot do things better, but have a careful think of how the changes will effect everyone. When it is busy, the changes could delay IFR as well as VFR.

..... And then Dick will have a lot more aerodromes to get held up at in his Bell and write about it on pprune. There will be ail grown threads everywhere.
