What is the maximum height of Class B airspace?

The maximum height of Class B airspace typically extends from the surface up to 10,000 feet Mean Sea Level (MSL). Class B airspace surrounds major airports and is designed to manage the high volume of air traffic, ensuring safe separation between aircraft operating at different altitudes and speeds. This airspace is established to include the airspace above the airport and allows for a controlled transition from the general aviation areas to the busy airways where commercial jet traffic operates.

This height of 10,000 feet MSL is important because it provides a safe vertical buffer above the surrounding terrain, as well as a clear operational space for both commercial and general aviation traffic in and around busy airport environments. Understanding Class B airspace and its altitudes is crucial for pilots, as it includes specific entry requirements and operating rules that enhance safety and efficiency in crowded airspace.
