What is Class B airspace primarily designed for?

Class B airspace is primarily designed to manage the high density of air traffic surrounding the nation's busiest airports. This airspace typically extends from the surface up to 10,000 feet above sea level, in a generally upside-down wedding cake shape, to accommodate a variety of aircraft types including commercial airliners, cargo planes, and private aircraft.

The structure and regulations of Class B airspace are established to ensure safe and efficient operations in and around these major hubs, which often experience a substantial volume of takeoffs and landings. Pilots within this class must be equipped with specific procedures, communication, and transponder requirements to help maintain order and safety in the busy environment.

While other classes of airspace serve different purposes, such as managing operations around smaller airports, military activity, or general aviation, Class B is uniquely tasked with oversight over the most trafficked areas of the airspace system.
