Keeping Aircraft Safe without Radar: The North Atlantic Tracks

  • Published on May 14, 2018
  • Over the North Atlantic, there's no radar coverage: so how do air traffic controllers keep planes safe? The answer, at least in part, can be found at Nav Canada's Gander Area Control Centre in Newfoundland. The North Atlantic Tracks are like freeway lanes in the sky, if freeway lanes were stacked a thousand feet on top of each other.
    More about Nav Canada and the tracks, and the new standards they're introducing:

    If the lighting and shots seem a little odd here, it's because -- for good reason -- I wasn't allowed to film too close to the air traffic controllers. They're a bit busy.

    Why is no one talking about how awkward it must have been for Tom to be standing in an airplane talking to himself. I know the camera is there but it still must have been a sweaty situation.

    Tom, do you have any insight on the accent of the Nav Canada controller in the video? Is that a typical Newfoundland accent? It's not something I hear every day. It has many features of RP, when contrasted with Gen. Am.

    Interesting ... I knew there were radar dead spots in the world, but never thought that the North Atlantic would be one of them. Surely there is at least military radar in the US looking for incoming -Soviet- Russian planes and missiles that might come from that direction? Though maybe they're not willing to share their data with civilians... it might even preclude the installation of any civilian long-range/OTH scanning radar setup because of potential interference...?
    I expect the radio transmitters mixed with (the surprisingly slow uptake of) GPS will eventually make the need for it obsolete, though, as planes can check in every couple of minutes with a quick chirp containing their tailcode, lat/long, speed/heading and altitude. Much like MH370 was revealed to have done (though, "phoning home" to Boeing rather than informing ATC in any way) for quite a long time after going off-track and off-radar...

    This video is not very clear. What is the problem with there being no radar, how do planes normally behave when there is radar, how to they talk to the airplanes? Too much information, not decently explained.

  • T Duke Perry

    I genuinely wonder, if there was no air traffic control systems of any kind and it was an absolute free-for-all, what are the odds of any collision at all? I assume there are a lot of factors in this, including visibility conditions and sheer volume of traffic, but I genuinely think it would be an interesting question. Because if planes just went where they wanted, and didn't have to go over specific paths, but had the whole sky to choose where they wanted to go, there might not be enough planes where two of them in the same space at the same time is even remotely likely. Probably no more than a 1% chance.
    I see the only problem with this theory being the fact that they plan their routes along certain paths for the sake of efficiency more than anything, so they wouldn't be randomly distributed.
    I'm not saying we should get rid of ATC because it's useless or anything, I'm just thinking out loud.

    • T Duke Perry
      T Duke Perry 6 months ago

      Okay, but is that the actual number of this bizarre scenario? Because in that case, let's say it's 0.001%! There's a lot of sky!

      1% of 31750 flights expected today through eurocontrol atfcm network is 317 aircraft crashes just in Europe. It would be disaster. We have mid-air collision every now and then even with ATC and TCAS.

    Is that what a Newfoundland accent sounds like? I’m very familiar with the more common Canadian accent but I’ve never heard this accent before. It sounds like an Irish person trying to mimic an American accent. And very subtle too, I almost didn’t notice it.

    • Kris
      Kris 6 months ago +1

      That's fascinating to me. I'm from Michigan so half of my family is from and lives in Canada. I'm very familiar with the standard accent as well as Quebecois. I never knew Newfoundland had a distinct accent. So cool.

    • kairon156
      kairon156 6 months ago +1

      Actually I suspect he's talking more slow than he normally would which might be where the American accent comes to play.
      Newfoundlanders being Canadian tend to be polite when we know our accent will be heard by non Newfies and slow down.

    so, basically... it takes _this_ to make sure planes don't crash into eachother. why would you be able to avoid collisions if you had your own personal plane, I mean... flying car? you can't that's why flying cars are a terrible idea.

    radar is just a way for planes and ground crews to detect planes and ground crews (or obstacles).
    if you have a SATELLITE, reading TRANSPONDERS, on both the planes and the ground stations, and you know the topography, that you mapped with a SATELLITE..... why do you need the radar for!? XD

    I'm a bit confused as to why the location of the aircraft is not reported continuously and automatically by satellites relaying on board GPS data.
    There are centimetre range accurate GPS that operate to 50km altitude.
    Does anyone have any ideas?

    Grade 9 Take you kid to work day I was at a Nav Canada. My dad organized it as the company he works for works with their facilities out west, and he had plans to be at the facility all day. Got to spend part of the day on tour, and talking to these guys. Going in the operations room, and doing all sorts of cool stuff. Though this was well over a decade ago. Still a very memorable day. Thanks Dad! As soon as I saw the Nav Canada sign, my face lit up! Thanks Tom!

    Lufthansa names its airplanes after German towns.
    With two exceptions.
    During 9/11 all flights in US airspace were grounded and incoming flights rerouted. Naturally that left many, many passengers stranded. Gander was among those communities that had to accommodate the most grounded passengers. And they did it with amazing hospitality. Lufthansa thus named one of their jets "Gander" and another "Halifax"

  • Plum_ Pie

    why no GPS? honestly why not? put a GPS tracker on every bit of an aircraft and then you can never have another event like MH370

    • Plum_ Pie
      Plum_ Pie 6 months ago

      sorry if my logic is flawed here but cant you get handheld GPS devices, meaning you could very easily have a battery backup that runs the GPS transmitters in case of power outage. not sure how to solve bandwidth but still one GPS transmitter per plane doesnt seem like it would be too hard seeing as there are millions of devices already using GPS with not extra cost for the bandwidth used.

    • QuassSeabass
      QuassSeabass 7 months ago

      1) That's an insanely high level of bandwidth. Think about how many aircraft are in the air at any one time, all sending data at eachother. 2) You're only moving the problem back one step. If an aircraft loses electrics outside of radar coverage, then there's no GPS signal so nothing really changes

    • QuassSeabass
      QuassSeabass 7 months ago +1

      Normally aircraft show their locations with something called a Secondary Surveillance Radar, but outside of radar coverage that isn't possible. Satellite position updates are becoming more common as the acurracy of GPS data increases but we're a while away from those yet
