What we all need to understand is that the AUSNAS is a degradation of services and therefore protection for no financial benefit; so why do it?
The 2b changes for November have C airspace significantly reduced and E significantly increased; some G gets replaced by E...
IFR and RPTs currently fly mostly in C or above, unless operating to an aerodrome in G. Many company ops say don't go into G unless it is unavoidable (QFA for example). Every RPT and IFR will now be forced to fly in E, unless you have a unrealistic profile. This is a reduction in services and protection, with not $1 saved; infact many spent/wasted training and promoting this project. Again cost benefit?
AUSNAS is less for no cost benefit, but hey if you are VFR, you're going to luv it, because you can do what you want and it won't cost you a thing... Will the end result be increased IFR charges, as no VFR will pay for anything except aerodrome charges...
