Controlled airspace is subject to certain pilot qualifications, operating rules, and equipment requirements. For IFR operations in any class of controlled airspace, a pilot must file an IFR flight plan and receive an appropriate ATC (air traffic control) clearance.

Each Class B, Class C, and Class D airspace area designated for an airport contains at least one primary airport around which the airspace is designated.
