Class B airspace typically surrounds which type of airports?

Class B airspace is specifically designed to protect the operations of the busiest airports in the United States, typically characterized by a high volume of air traffic. This airspace structure allows for the safe and efficient management of large numbers of aircraft arriving and departing from major cities.

The dimensions of Class B airspace typically extend from the surface up to 10,000 feet above sea level in a tiered configuration, which helps facilitate the flow of traffic into and out of these busy airports. The requirements for entering Class B airspace include specific pilot qualifications and aircraft equipment, further indicating the importance of safety and control in such high-traffic areas.

Other types of airports, like general aviation airports, military airfields, or remote airstrips, do not generally require the extensive management of air traffic to the same degree, as they handle significantly fewer operations and traffic in comparison to a busy commercial airport. This distinction underscores the importance of Class B airspace as a critical component of airspace management around major commercial transportation hubs.
