Definition of Class C Airspace
Class C airspace is a designated area surrounding airports that have a control tower and are serviced by radar approach control, with a certain number of IFR operations or passenger numbers. It extends from the surface up to 4,000 feet above the airport elevation, as charted in MSL. The configuration of each Class C area is tailored to the specific airport, but typically includes a 5 NM radius surface core area and a 10 NM radius shelf area. The surface core area extends from the airport surface up to 4,000 feet, while the shelf area begins at 1,200 feet above the airport elevation and extends up to 4,000 feet. The purpose of Class C airspace is to provide controlled airspace for IFR operations and to manage the flow of air traffic in and out of busy airports.
