Mysteries of Flight: Circular Runways? Crackpot Idea Or Brilliant Solution?
The idea behind circular runways isn’t new, but it has gotten increased attention lately. Could it be the key to increasing landing capacity nationwide, or is it just as crazy an idea as it seems?
By Plane & Pilot
Round airports have been around since the early days of aviation, because that layout allowed the notoriously lightly wing-loaded planes of the day to land directly into the wind no matter which direction it was blowing. But circular runways are another thing altogether. And while the idea might seem totally crazy at first blush, there’s some serious research being done to see if circular runways could achieve increased airspace system capacity, which absolutely is limited by the number of available runway ends. With a circular runway, there would be, theoretically, an unlimited number of runway “ends” at any given airport.
The Idea
With a circular runway, planes could approach to land from many different angles, so you could have multiple planes on approach simultaneously. And you could have planes taking off and landing at the same time as well. Great, in theory.
But in order for planes to be able to navigate the turn, the runway would need to be banked, as an oval racetrack is. Planes would approach to land and then turn into the curve as they landed, touching down and continuing to turn with the runway—there’s no going straight with round runways.”
