Airspace capacity deals with proximity of airports to one another.

• A. The proximity of airports to one another
• B. The total number of flights per day
• C. The length of a flight corridor
• D. The capacity of the navigation aids

Answer: (A)

Airspace capacity relates to how much traffic the airspace can safely handle, usually measured as aircraft per hour, and is shaped by how the airspace is organized, including sector design, controller workload, and separation standards. When airports are close to one another, their arrival and departure corridors and en-route routes often overlap more, increasing potential conflicts and the need for tighter spacing or holds. This heightened complexity reduces the throughput that can be managed without compromising safety, so proximity of airports is a major factor in determining capacity. The other ideas describe demand (total flights per day), routing length (which affects efficiency but not capacity directly), or a separate concept (navigation aid capacity), none of which capture how the physical arrangement of airports limits how much traffic the airspace can handle.
