The two categories of airspace are: regulatory and nonregulatory. Within these two categories, there are four types: controlled, uncontrolled, special use, and other airspace. The categories and types of airspace are dictated by the complexity or density of aircraft movements, nature of the operations conducted within the airspace, the level of safety required, and national and public interest. During the presentation we will cover various types of airspace and the operational requirements for each type.  Please download and review FAA-H-8083-25C Chapter 15 on Airspace at the bottom of this announcement.
