Airspace

The National Airspace System (NAS) was created by the FAA to make the U.S. airspace safer for all aviation and to protect persons and property on the ground. It is a complex network of both controlled and uncontrolled airspace, including air navigation, airports, and the density of aircraft movement within.

The NAS has two categories of airspace: regulatory and non-regulatory.

Under regulatory and non-regulatory categories there are four types of airspace:

  • Controlled airspace

    • Class A, B, C, D and E​

  • Uncontrolled airspace

    • Class G​

  • Special Use

  • Airspace Speed Limits
