The two categories of airspace are regulatory and nonregulatory. Within these two categories are four primary types of airspace: controlled, uncontrolled, special use, and other airspace areas. The structure and classification of airspace are designed to accommodate varying levels of aircraft activity, operational requirements, safety considerations, and national interests.
The categories and types of airspace are dictated by the complexity or density of aircraft movements, the nature of operations conducted within the airspace, the level of safety required, and national and public interest. Figure presents a profile view of the dimensions of various classes of airspace.

In addition, sectional charts provide pilots with a graphical representation of airspace boundaries, operational restrictions, and navigation information. Understanding how airspace is organized and depicted on aeronautical charts is essential for maintaining regulatory compliance and ensuring safe flight operations.
The following sections explain the major categories of airspace, special use areas, and the role of air traffic control within the National Airspace System.
