airspace capacity

airspace capacity

The proximity of airports to one another, the relationship of runway alignments, and the nature of operations—IFR or VFR (instrument flight rules or visual flight rules)—are the principal interairport considerations that affect the airspace capacity of a master airport. If major or secondary airports are closely spaced, they will share a parcel of airspace. Hence, there may be some reduction in IFR capacity resulting from the intermixing of traffic within that parcel of available airspace.
