Air Traffic Control Zones Look Nothing Like The Country
Interestingly, the air traffic control in the United States isn’t broken up by state, but rather by zones and sectors. Throughout the continental US, there are 21 zones, as illustrated on the above map. Each of these zones is centralized around a major city, such as Houston, New York, and Washington D.C.
But that’s not where air control ends. Within these 21 zones, there are sectors and 50 miles in diameter of airspace. Within each given portion of airspace is where all of the country’s airports are located, each with its own five-mile radius.
