How many layers does Class C airspace typically have?

Class C airspace typically consists of two layers. This airspace is structured to ensure safe and efficient operations around busy airports. The lower layer generally extends from the surface up to a certain altitude, usually around 4,000 feet above the airport elevation. The upper layer of Class C airspace is typically a shelf that extends above the lower layer, often up to 4,000 feet above the airport's elevation as well. This tiered structure allows for better management of air traffic, especially in areas with significant commercial and general aviation activity. The design of two layers helps controllers effectively manage the flow of aircraft departing and arriving at the airport while maintaining safe separation from those in the vicinity of the airspace.
