Point of note to consider. Using the logic that there is a massive increase in controlled airspace (E), there are massive restrictions placed on VFR aircraft as well.
A class is introduced above E over all of CTA. The J curve for example has today (pretty much) G to A085, some E between SY and CG A085 to F125, C F125 to F285 and A above. Post NAS the C goes and E and A come in with A above F180 all the way up. So 9000 feet of potential VFR activity is gone. That's some 35% ladies and gents.
So here is the NAS model simplified.
More Controllers required.
Less service given to more aircraft
Costs Increase
VFRs have a 35% reduction in allowed airspace
VFRs must remain clear of IFR routes and all approach and departure paths
There are no frequency boundaries
There are no frequencies
Did I mention that it is going to cost more?
Aircraft IFR can enter supposed controlled airspace without a clearance (IFR Pick UP)
Add to this that the exemption for Flight without a transponder in E within 40nm of a D tower is added (no glider flying in the E steps above Caboulture or in the Steps above Alice Springs I'm affraid guys).
If I were a VFR pilot I would feel pretty cheated. But hang on, this is all designed for the VFR pilots, Isn't it?
