At what altitude does Class B airspace typically reach its top?

Class B airspace typically extends up to 10,000 feet above mean sea level (MSL). This type of airspace surrounds the busiest airports and is designed to manage air traffic effectively, ensuring a safe environment for both commercial and general aviation operations. The structure of Class B airspace usually consists of several layers, with the lower limits starting near the surface and extending up to 10,000 feet. Understanding this altitude helps pilots to navigate and comply with air traffic control requirements when operating near busy airports. The other altitude options do not represent the typical top limit for Class B airspace, as it generally does not extend beyond 10,000 feet.
