What it means for the towns around SJC
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 SJC switches direction, the planes over these towns change too. Each town page shows the usual paths for both directions on a street map:
- Santa Clara, CA · 2 mi
- San Jose, CA · 2 mi
- Sunnyvale, CA · 6 mi
- Fremont, CA · 13 mi
- Redwood City, CA · 19 mi
Why SJC 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.
SJC's runways: 12L/30R, 12R/30L. 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.
