Geoff thanks and re yr reply below,
"10JQKA - Class G, in the US is confined to the airspace below Class E. Variously below 1500, 1200, or 700 feet. It is therefore very limited and because US Class E does not require transponder equipment for VFR flights, indistinguishable from Class E."
Yes I understand the US G is a very thin band of G, but there is no DTI provided to IFR which may be a good reason to have lots of E in the case of the US ?
But our G has mandated DTI to IFR, a hangover I assume of the disbanded previous Flight Service functions, So could it not be possible that with our G providing a higher service level as a hybrid than of ICAO G that in fact there is no need to provide low E and is a waste of time and resources and will only cause delays compared to current G operations ?
Have always thought that if the powers that be had to tick the extra CTA box for whatever reasons it would be much smarter, neater and operationally less restrictive to instead bring the E base inland down to A085 from F125 and have a uniform base of A085 for E everywhere, surely some standardisation like that would be more valuable/efficient than a patchwork of variable E bases ? Have a look at the Hunter Valley proposed map A045 east of what used to be Point Lookout/Singleton then base A065 West of that until you run out of J-curve then F125 and 2 circular areas of base A085 one between CH and TW and other one between WLM and TW ! Good luck with situational awareness flying there and knowing what the base of CTA is at any point on your multi leg flight.
