Class B airspace generally extends from the surface to what altitude?

Class B airspace is designed to manage air traffic in busy terminal areas around major airports. Generally, this airspace extends from the surface up to an altitude of 10,000 feet mean sea level (MSL).

This structure allows for efficient separation of aircraft arriving and departing from the airport while ensuring a safe operating environment for all types of aviation within that airspace. The precise vertical limits of Class B airspace can vary by location, but commonly it covers the range from the surface up to 10,000 feet MSL, accommodating a large volume of traffic and providing necessary air traffic control services.

As a result, the knowledge of the Class B airspace altitude is crucial for pilots operating within or near these busy airspace zones, as they must comply with specific regulations and requirements for entry and operation.
