KZAB's airspace is divided both geographically and altitudinally.
KZAB's primary subdivisions are known as specialties. There are five different specialties known as the North, East, Southeast, Southwest and Northwest. Each specialty is broken down further into 7 or 8 sectors.
By altitude, KZAB comprises 7 ultra-high sectors, 16 high-altitude sectors, 13 low-altitude sectors, and 3 low-high sectors. The vertical strata of these sectors vary greatly depending on the geographic location covered and the variety of traffic the controllers work.
