There's an Air Highway That Keeps Planes From Crashing Into Each Other

Illustration for article titled Theres an Air Highway That Keeps Planes From Crashing Into Each Other

If you’ve ever taken a transatlantic flight, here’s a terrifying thought—for a huge portion of that trip, your plane had no RADAR. The good news is there’s essentially a ten-lane highway over the north Atlantic Ocean that keeps flights between, say, New York and London, from getting too close to each other.


As Wendover Productions explains, RADAR only extends about 250 miles from land, so all flights taking the shortest route over the Atlantic rely on an air traffic control center in Gander, Newfoundland. The night before, airlines send Gander a list of which flights will take the sky highway, which is actually called the North Atlantic Tracks. Once nearby, pilots request a flight path from one of ten lanes.

Each lane begins and ends at named waypoints. The pilot is told by Gander which point to head towards, programs the ending waypoint into autopilot, and the rest is smooth sailing—all because Gander does the difficult organizational work of keeping the hundreds of planes making the crossing on non-intersecting tracks with at least 140 miles separating each plane.


Air travel might be a dull, cramped pain in the ass, but next time you land on the other side of the ocean, remember to thank Newfoundland.

I could probably ask this question to Google but I enjoy you guys so much more: I fly across the Pacific at least twice a year, and the route to NRT/ICN from LAX/SFO/SEA typically goes north, up the coastline of Alaska and Russia and down. Does this have anything to do with RADAR availability or is there some other reason for this course?
