The United Kingdom’s air traffic control entity, NATS, recently published the third in a series of computer-generated videos depicting a typical day’s traffic in the skies controlled by the National Air Traffic Service.
The first two, Europe 24 and North Atlantic Skies, were impressive enough. But this one, which focuses on air traffic over the British Isles, is of particular interest because I’ve flow in and out of the London area on many occasions. I can imagine myself as one of those tiny dots (“which one am I”?), zipping around the skies of southern England like a 35-ton firefly or launching westward toward America in the manner of a sleek metal bullet being fired across a placid lake.
This clip, entitled “UK 24”, is also worth watching because it breaks down the traffic by type: military, commercial, helicopter, light GA, and so on. After watching the video a few times, I was struck by the paltry ratio of general aviation to airline activity — the polar opposite of what we’ve traditionally seen in the States. Perhaps that’s because the airplanes operating without ATC services are not modeled in this video. Either way, it’s a sad (and unintended, I’m sure) commentary on the state of grass roots general aviation in Europe.
I wonder if the FAA provides a similar visualization of flights over the continental U.S. It would certainly be an interesting comparison. I imagine it would make a dramatic statement about the size and scope of traffic in the national airspace system. NATS controls an average of 6,000 flights per day in U.K. airspace. According to the FAA’s Air Traffic Activity System, the U.S. sees ten times as many flights over the same period. And that doesn’t include non-participating VFR targets which, unlike our British cousins, outnumber IFR operations by several orders of magnitude.
A visualization of all American air traffic would probably be so overwhelming that portions of the map near major metropolitan areas would be nothing but a vibrant ball of blue. Here’s hoping it stays that way.
