Seems to work at London City - article here
I think London City was a good place to start.
No VFR circuit traffic, London (apparently the best in the world) approach/departures control, one runway, small PPR parking area.
High speed internet circuit between London and Swanwick, satisfying the 1 second video latency requirement.
None of that applies to either Ballina, West Sydney Airport or Hamilton Island, two of which will be Class D CTRs.
I anticipate the Tower Controllers having to be close to the antenna towers, which makes both Ballina and HMI a marginal improvement at best. We already know that West Sydney will be in "centre" close to the airport so once again the savings are confined to building, there do not appear to be staff savings.
We know it works, assuming the standards applied to the cameras, are the same as applied to eyeballs. I only hope that CASA has done it's homework!

Yes Geoff, So Many Questions
Airservices has a record of handling technological innovation. Consider a few::
July 7th 2000: Press report
Air traffic controllers at Sydney airport lost radar and radio contact with 20 aircraft for up to 15 minutes during a peak period Thursday evening, an airport spokesman said Friday.
A two-minute power blackout at 6:30 p.m. triggered a computer failure that took further 10 minutes to restore, said Richard Dudley, a spokesman for Air Services Australia, a government-owned corporation that manages the airport's air traffic control services.
During that time, planes carrying more than 1,000 passengers were forced to circle above the city with no contact between flight crews and the airport control tower.
Dudley said he did not believe there had been any near-collisions between the planes. But he called the incident extremely serious and said an investigation would be held.
''It is of great concern to us to establish why that power outage occurred, particularly as we have layers...(of) power supplies underneath.''
''For this sort of situation to occur is extraordinarily rare and that's why we want to get to the bottom of it as quickly as possible,'' he said.
BUT an electronics technician had previously told Airservices and Sydney airport that their back up power supply would not work as expected because the signal sent by the Control Center asking for back up power to start up was not the signal the back up power system was expecting.
His report was poo-pooed. He's only a techo, our engineers say it will work as intended. He was right, they were wrong.
I know a fellow who was flying in southern NSW that night. He recalls the sudden excitement on Center frequency. Call after call. We're on descent into SYD. There is nothing there, no lights, no comms, no answer on any frequency and it's just a big black hole. Repeated many times. MEL CEN of course had no idea and they had no comms with SYD either. SYD did not even have hand held battery back up VHF coms, nothing at all. Some aircraft diverted on their own initiative, no separation except look out the window at night, good luck. My mate is a chicken so he pulled a U-turn and landed in Albury and he laughed and he laughed and he laughed.
Back about the same time, the money making Airservices decided pilots had to pay for the phone call to contact the Briefing Office and arranged for phone cards to be sold so pilots could use them in remote locations. The safety case was taken over to the people at CASA and they were told in no uncertain terms this is none of your business, we are required to charge for our services so the safety case is just for your information. CASA apparently did not argue the safety effect of charging but rather asked what the back up was for this new 1-800 number. Not our problem says Airservices, we pay Telstra for a service so it up to them.
Shortly afterward the pavement was dug up close to the Canberra Casino in Allara Street near the access path to the Airservices Building. Cut the cable, no 1-800 briefing, no backup and it took days to fix, if I recall correctly.
I'm fascinated that Airservices are seriously intending their first remote, electronic tower is going into WSI, not a minor regional airport but a seriously busy one in the biggest city in our nation.
Just as intrigued that they are not making this installation even on airport with some limited form of look out the window vision even as a backup.
Amazed that this is a location where even a minor failure is going to have delay repercussions on traffic all over the country.
WOW, some big cajones here.
Like the hugely experienced Geoff Fairless wrote above, I'm retired too, "So many questions".
I just hope AsA really does their homework on the safety case, the FMEA, the redundancies etc on this one..... or as another expert ex-FSO on here says: WOT CUD POSIBLY GO RONG...???

In fact the centre could be 300000km away and still be in spec.
Like others I do have concerns over execution though.

If it’s an off the shelf product as proven in LCY etc then can’t see the issue.
If it’s new tech commissioned by ASA….. then all bets are off.

It is far more widely used in Europe than most people think...and expanding rapidly. I believe Canberra will be the first digital tower in Australia but I could be wrong.
Thread Starter
A reasonable coverage of the state of the technology today. I notice the model proposed for West Sydney didn't feature but a couple of working operational examples were well presented.
When I visited the Heathrow facility last year the controllers were full of praise for the "extras" such as glare removal, seeing "through" terminals and the ability to know exactly when an aircraft was "clear" of the runway so a landing clearance for the following aircraft could be issued.
Shame about the delays in FAA land - but that seems to be par for the course with adoption of new technology there. Old hands will remember that TAAATS, for all its quirks and faults, had ADS/C and CPDLC available at operational consoles well before their counterparts in Oakland.

I'm retired so I probably do not have access to the required separation standards; however,
Camera images are not visual separation as defined by any manuals I have access to, the usefulness of a control tower is (was) all about visual separation.
Radar separation between successive aircraft is 3NM, typically visual separation can accommodate close approaches, successive departures on diverging tracks, and go-arounds until a radar standard can be applied.
Eyeball separation has no tolerances applied to the image in the controller's brain. The eye is presumed to have an uninterrupted power supply, is backed up by the eyes of other tower controllers, has an advanced display system called the retina, and an advanced intelligence system attached that can instantly detect a subtle deviation from the cleared flightpath or taxiway. What tolerances will be applied to artificially generated images shown to a controller on a television screen? The new services will also be classed as screen-based, hence subject to the screen break requirements for the controllers = more controllers.
I love the identification capabilities of the camera system, but, once again, does the aircraft have to squawk ident to ensure the label is correct?
So many questions.......

Rumour has it Airservices has advertised internally for expressions of interest to work at WSI “Tower”.
Two different sources have suggested that holding a Tower Rating is now not required???
Well what do you expect, its not a TWR!
A more realistic solution would be to get the staff from ESI Tower (real Tower), oh hang on Airservices can either staff WSI or ESI but not both!! Yikes!
To facilitate noise sharing and utilise staff at SY to the max, (well they are making > $$$$ 1/2 million, every hour will be divide into 15 min sections WSI Departures 0000 - 0015, ESI Arrivals 0015 - 0030, WSI Arrivals 0030 - 0045 and ESI Departures 0045-0100.
Everyone happy! Bewdiful!!!! Bob’s your uncle…Bound to work??

There's an internal ad for EOI to SY tower, I haven't seen the WSI one. No tower rating required "Appropriate training will be provided should you be required or wish to cross domains or streams."
Interesting, I guess they're finally seeing the writing on the wall and giving up on getting staff from the TCU across to the tower. I know of a couple of NZ controllers that want to come to SY, but the best AsA could offer them was BK. Maybe get them back on the phone...?
