What is the altitude range for Class B airspace?

Class B airspace is designated to ensure the safe integration of various types of air traffic around major airports. The altitude range for Class B airspace typically begins at the surface and extends up to 10,000 feet mean sea level (MSL). This allows for the management of aircraft during takeoff and landing phases in busy airspace, accommodating both commercial and general aviation traffic.

The structure of Class B airspace usually consists of a series of concentric circles around major airports, with the lowest circle starting at the surface and layering up in altitude. The upper limit is set at 10,000 feet to maintain safety and separation from other classes of airspace that operate above this altitude. Pilots are required to receive explicit clearance from air traffic control to enter Class B airspace, ensuring a tightly controlled environment that helps to prevent collisions and enhances overall safety.

In summary, Class B airspace not only facilitates a busy air traffic environment but also defines a specific altitude range that helps maintain safety for all users operating in proximity to significant airports.
