John Glenn Columbus International (CMH) picks its runway by the wind: planes take off and land into it, so the runway in use changes when the wind does. The live box below works it out from the latest airport weather report. Over 23 days of recorded flights, CMH landed toward the west about 87% of the time and toward the east about 13%.

What it means for the towns around CMH
Arrivals line up on the opposite side of the airport from the way they're landing, often 10 or more miles out for a busy airport, and departures climb out ahead. When CMH switches direction, the planes over these towns change too. Each town page shows the usual paths for both directions on a street map:
- Reynoldsburg, OH · 5 mi
- Columbus, OH · 6 mi
- Westerville, OH · 9 mi
- Grove City, OH · 13 mi
- Dublin, OH · 14 mi
Why CMH changes runways
Landing into the wind slows a plane down over the ground, so it needs less runway, and taking off into it gets a plane flying sooner. When the wind swings around, often with a front or a line of storms, the tower turns the whole operation around: arrivals and departures move to the other end of the runway. Busy times, construction and low clouds can also change which runways controllers use.
CMH's runways: 10R/28L, 10L/28R. A runway's number is its direction on the compass with the last zero dropped, so runway 9 points east (90°) and runway 27 points west (270°). L, C and R mean left, center and right for side-by-side runways.
