What is generally the maximum altitude for Class B airspace?

The maximum altitude for Class B airspace is generally 10,000 feet MSL (Mean Sea Level). Class B airspace is designed to manage the complexities of air traffic around the busiest airports, where numerous commercial flights are in operation. This airspace typically extends from the surface up to the specified ceiling, which often reaches up to 10,000 feet.

It's important to note that while Class B airspace can have various vertical limits, 10,000 feet MSL is the cap commonly associated with its structure, especially surrounding major airports. This distinction is crucial for ensuring safe and efficient flight operations in crowded airspace. Understanding Class B airspace and its limits is fundamental for pilots and air traffic controllers to maintain safe separation between different types of aircraft operating within this complex environment.
