What is one of the primary purposes of Class B airspace?

Class B airspace is designed primarily to manage traffic around major airports. This airspace typically surrounds the busiest airports where there is a high volume of both commercial and general aviation traffic. The structure of Class B airspace usually consists of a series of concentric circles extending from the surface up to a certain altitude, which enhances safety by organizing the flight paths of aircraft operating in and out of these busy airports.

By establishing Class B airspace, air traffic control can ensure that departing and arriving aircraft are properly sequenced and separated, reducing the risk of midair collisions and allowing for efficient operations. Pilots operating within this airspace must adhere to specific communication and clearance requirements, which centralizes and organizes air traffic in these critical areas. This structure not only improves safety but also optimizes the flow of air traffic in and around major airports, effectively coordinating the substantial movement of aircraft.
