back to article London City airport swaps control tower for digital cameras

London’s City airport is replacing its air traffic control tower with zoomable cameras worked from a base in Hampshire, according to reports. City, a small business-focused airport tucked into the capital’s Canary Wharf district (aircraft landing from, or departing to, the west of the airport actually fly between the area’s …

Re: Why?

Because someone is making a lot of money from this being implemented, and stands to make a lot more money when other airports want the same tech.

Don't be fooled in to thinking this is for safety or anything like that. It's being done for cold hard cash.

Re: Why?

The why appears to be so they can removal all structures on site and replace them with new ones to handle more passengers. This is more money as more flights will use the runway.

There's something comforting about knowing that the people responsible for ensuring that the metal box you are sharing with several thousand gallons of high octane fuel are guiding it down from a position very close indeed to where there will be a smokey yellowy-orange fireball if they get it wrong. ;)

It's not all "cyber"

How physically secure are the cameras in question, be it cables, paint or laser interference?

What risk from a power cut?

And so on.

Re: It's not all "cyber"

The correct question is how much *more* risk does damage to those systems represent versus a tower on site. I suspect the answer is "not much". Given how inter-connected air traffic control is, there are probably critical cables and critical cameras and critical networks at every tower, whether the tower is a real building or an office space fifty miles away. If someone starts pulling cables or throwing lasers at your real tower it's going to be shut down just as surely as a virtual one.

The higher risk elements are going to be that this is all digital. If they're shut down, or if the (presumably new) software doesn't perform, they're really shut down. There's no degradation of service, with binoculars and manual tracking, it's just shut. They can probably only get away with this because City's flights can easily be absorbed by Luton, Gatwick, Heathrow and Stansted.

Despite all the much-trumpeted built-in redundancies, experience has shown that all it will take is a hung over JCB | Back-hoe | Ditch Digger driver to turn it all to rancid dingo kidneys.

There's also Southend, and the last couple of times i've come into City we flew over the Essex coast and up the Thames.

Re: It's not all "cyber"

You can ask the same questions about the NATS radar sites around the country - without them we can't see the planes and there's not normally much of an overlap between each one, so if one went out you'd have a large dark section.

There are procedures in place to deal with the loss of a radar tower, which is extremely unlikely due to the multiple layers of redundancy and the amount of maintenance etc that gets done on these sites.

Re: It's not all "cyber"

*3 diggers - when NATS say they have redundant paths, they really mean that. Physically separate cables that leave the network buildings (normally in pairs but in this case I reckon in threes) in different directions going to different cabinets going to different exchanges and going over different physical bearers in different trunks all the way to Swanwick, which has at least 4 different incoming links in different directions from different cabinets from different exchanges etc.

BT got into a bit of trouble with them years back for accidentally re-routing a cable into the same physical trunk leaving the head office building (not the ATC building) so they take this very seriously.

And those three independently routed cables will all pass the same disused church at some point on their route...

Well ..

They don't really fly between the towers you know. Though it is a bit weird to be in a plane looking up at people in the Shard as you fly past.

Re: Well ..

Came here to comment just that, the glidepath is steeper than normal for a City Airport approach. The planes are about 2,000ft when they fly over the Isle of Dogs - more than double the height of the buildings there. They've barely got their wheels down by Canary Wharf. The same goes for the Shard, which is even further out. You're not "looking up" at the Shard in a plane, unless something has gone horribly wrong!

Used to live between CW and LCY, loved watching the planes, more than made up for the noise :-) From the ground, it looks a lot closer, but only because we are terrible as humans at gauging vertical distance.

Eyeballing?

Sounds great when everything is working to plan. But can you beat an eyeball when it ain't going to plan? I mean a plane turning left instead of right. Looking out on City Airport in 180 degree 3D reality colour the anomaly should register. But will it register if it isn't on the screen the remote controller is currently looking at?

But then does anybody look out of the windows these days? I've never seen anyone cleanin'em

Re: Eyeballing?

Some years ago it was identified that accidents on the ground weren't decreasing at the same rate as those in the air, in fact taxiway collisions, runway incursions and wrong runway taxis were increasing with heavier airport use, so systems were introduced to monitor planes on the ground and raise alerts if they went where they shouldn't be.

Re: Eyeballing?

Cleaning gets done at night when there's no traffic at Heathrow or City - and when it's dark so looking out of the windows is less important

But the angle is misleading and the planes really pass a long way to the north of the tall buildings.

"redundancy is assured"

I'm sure the current ATC controllers will be pleased.

It's just as well that computers never crash nowadays, because now the planes will too. Those times when the ATCs had to jot down the last plane positions and flight nos. from memory then manually co-ordinate landings will be just a memory.

What they wont mention is the next cost-cutting step which will be to move the NATS control centre to the cheapest offshore location.

I seem to have left an important part of my plane somewhere in a base in Hampshire.

Extra redundancy would have meant windows

Saw this on the news last night. My first thought was I can see the utility in the technology, but why host it 50 miles away? If it does all go tits up, it would be reassuring to know the controllers could still go and look out the window if they needed to.

Re: Extra redundancy would have meant windows

Cost.

They could have made a room available just by the airport, with no cables to be cut..

But hey, that is expensive. Also that is reasonable.

Also..HD screens. Really? A wall of frameless 8k screens would allow the controllers to use binoculars.THAT would make sense...but hey 40 8k panels consumes a huge amount of bandwidth.... I wo der if their solution is H264 compressed video..that adds latency..a lot. Forvet about the fiber latency of maybe 2ms..the problem.here is compression and display. They are landing planes..problaby with a 100ms lag...that is unacceptable.

Re: Extra redundancy would have meant windows

Because it's being put in a room in the existing Swanwick control centre which currently handles en-route traffic for the southern half of the UK and the London Terminal Control Centre, plus General Aviation advice and monitoring services.

"They are landing planes..problaby with a 100ms lag...that is unacceptable."

Umm, you do realise that the controllers in the tower (real or virtual) don't actually *control* the aircraft, and if it gets to the point where having a fraction of a second of lag in the virtual view leads to an incident, then things had already gone pretty badly wrong some time ago...

Now, I'm not saying I don't have some reservations about this idea, however aircraft can and do land and take off quite safely without any assistance from the tower controllers, and there will already be procedures in place to cope with loss of comms with a locally situated tower. So if things were to go completely T.I.T.S.U.P. with the virtual tower then it might make for an interesting few minutes elsewhere in Swanwick as the area controllers shuffle stuff around to cope with the diversions away from City, but it isn't going to cause aircraft on final approach to suddenly drop out of the sky.

No they don't. They fly (some distance) above them.
