Well, Gough was going to site the airport at Galston. Sydney folk best know Galston for its very deep gorge. A rather difficult spot to build an international airport - but that was the state of politics at the time.
That aside, flying school operators at Bankstown and Camden have been pleading for airspace design detail since WSI was just a thought bubble.
I’m predicting some form of VFR lane east to west over the top of WSI will be required for traffic to get over the Blue Mountains. Bathurst / Orange being a routine nav exercise for students. Realistically, following the narrow ‘gap’ through Katoomba limits the amount of serious tiger country between the coastal strip and the western plains.
The Bankstown and Camden training area may be pushed further south meaning the transit time for Bankstown traffic will get even more expensive for students. Training further south may start to impinge on Mittagong (which just got some Federal grant money), but it’s usually fairly quiet. Shellharbour (Wollongong) however, has already got crazy busy on the weekends. ADS-B is really proving its worth.
Interestingly, to the north, Warnervale on the Central Coast is also booming and also just won aero club of the year. All credit to them, and Bankstown’s loss will be their gain.
If RA-Aus does ever get C and D airspace access, let the fun in the Sydney basin really begin !
Oh, and of course everyone knows there has already been a landing at WSI……..about a year ago.
