ules, I think you need to read the requirements for horizontal splay allowances. Factor in road/rail access, taxiways, holding bays, parking space, fuel supply and storage in what is essentially part of the bay, other ground facitilities, nav facilities, expected noise footprints and the big one...NIMBY (Not In My Back Yard), and whether the runway is long enough to be useful for a fully loaded A380 or 747 plus the changes to the flight paths with another E/W parallel runway and I expect your proposal is going nowhere.

Newcastle Airport response to speculation
 

There is only one sensible location for the Next Sydney Airport.
Richmond.

Expansion Room (tick)
Train (tick)
Road (tick)
Runway (rick)
Wingeing losers that paid two much for there home and cant pay back
the mortgage (tick)

They did it in Kansai they did it for Hong Kong.
It's time we consider a man made airport a couple of miles off shore.
I think my taxes alone will pay for it.

How deep was the water at Kansai? How deep was the water at Hong Kong? How deep is the water a couple of miles off Sydney? Why not fill in Sydney Harbour, move the coathanger to Parramatta and have an east west runway?

hmm i agree, .. so dissapointing about williamtown though. it would be perfect there !

Matt,

Where would you expand Richmond? It's pretty hemmed in - Richmond town to the west, Windsor to the east (at least under the flight path)... and the road and rail would both need to be improved.

Unless it's just an 'overflow' or LCC facility (as Avalon is for Melbourne).

121.5,

For a start, Kansai and Chep Lap Kok are both in reasonably sheltered, relatively shallow waters, not open sea.

Absolutely correct. Richmond is too small for large capacity jet services and has no room to the east, west or south to expand.
It could handle freight, but the recent investment in ysbk by freight companies makes this unlikely. It is to far out of Sydney (1.5 Hours by train) to make it a reasonable prospect for regionals.

Richmond may be an option for small numbers of low cost carrier services, just like avalon. Passengers will pay less for a service that doesn't quite get them to Sydney. It doesn't really have any chance of becoming Sydneys next AP.
I don't understand why Nowra is so under utilised by Defence, surely some units can be moved there from willytown. It has every thing they need and they would still be on the eastern seaboard.

Then it's back to Willy, when the movements get to many move the RAAF, nice little runway at Evens Head to expend...:rolleyes:

Yeh. Cause we don't need to train fighter pilots... :ugh::ugh:

You just don't need to train them at Willy.....:ok:

The taxpayer trains them at willy... and they are going to have to fork out bigtime if they want to move it.

move them all up to tamworth ;)

I guess we will just have to wait and see what Macquarie have in plan for Sydney's next airport. Not really sure if the decision has anything to do with Immea government. Surely the next sensible stage would be to reduce the curfew at the existing Sydney airport.

Curfew
 

yeah but there is no way that Albanese will extend the curfew. The only reason we ahve a debate on a second sydney airport is because Albanese is from a seat next to sydney airport and one of his campiagn promises was to make sure the curfew in Sydney was not extended.

Suggestions to extend curfews and have overflows at other airports like richmond are only postponing the inevitable need for a second airport. Any current Government that implements policies to expand the capacity of sydney in this way is thinking short sighted. But then again which politicians ever think long term?

Richmond has plenty of room for a long N-S runway through the 10 threshold aligned probably 16 or 17. Of course there would have to be property acquisition and road/rail adjustments, but nothing significant (such as SYD 25 RESA at the Cooks River). The railway would also need efficiency improvements but this would be a massive political bonus. The advantage of Richmond over Badgerys is the "we can use it now" factor; it doesn't need the long runway until pressure mounts to move internationals or long leg domestics.

Williamtown is not and never will be part of Sydney's air passenger catchment. It will develop of its own course and can complement Sydney basin facilities.

I think Nowra is about to get busy with the move of all ADF initial helicopter training to the base with AIR 9000 Phase 7.

The temple and major housing project in the undershoot of one of the runways may pose a significant problem for jet operations. Deconflicting parachutes from tens of thousands of rotary movements will pose enough of a challenge in the short term.

Defence utilises Nowra just fine thanks, its great just the way it is. :ok:
Navy got rid of their jets a long time ago and Defence moved the parachute school here, which conflicts nicely with the helicopters, so can you all please go back to your Newcastle/Willy/Ric/Badgery's Ck idea and forget about us, we don't exist (unless your Navy).

I vote for Kooragang Int Airport. ;)
