Airspace Explained (the NAS)

Airspace Explained

The United States National Airspace System (NAS) is the most developed, complex and safest airspace system in the world. The NAS Operations Organization is responsible for planning, directing, implementing, overseeing, and continuously monitoring all programs related to air traffic control systems used by the FAA at the Air Traffic Control System Command Center (ATCSCC), located in Warrenton, Virginia, and throughout the United States. Airspace Explained provides a freeway guide to our sky’s airspace classes.
Via the NextGen’s program of modernization efforts, the FAA is creating new interconnected systems that fundamentally change and improve how the National Airspace System (NAS) users see, navigate, and communicate.

But at the most basic grass roots level and beyond, the NAS is experienced by pilots daily as a group of organized air mass locations; and within the boundaries of each location, laterally and vertically, a common set of flight requirements prevail.  Learning how the NAS functions, and understanding the necessary regulations that govern our airspace, insuring safe flight for both general and commercial aviation, is an essential building block for every pilot.

The following .pdf file outlines via text and graphics how the NAS classifies airspace, and describes the flight requirements for operations within Class A, B, C, D, E and G airspace as defined by FAA/NAS regulations.
