What is the definition of Class B airspace?

Class B airspace is defined as airspace that extends from the surface up to 10,000 feet Mean Sea Level (MSL) surrounding the nation's busiest airports. This airspace is designed to manage the high volume of air traffic in these regions to ensure safe and efficient operations for all types of aircraft, particularly during takeoff and landing phases.

This delineation helps establish a protective barrier around major airports, allowing for more stringent regulations and monitoring to prevent airspace conflicts. The operational requirements within Class B airspace include obtaining clearance from air traffic control for all aircraft wishing to enter or operate within this airspace. This is particularly important given the density of air traffic in these areas, where both commercial and general aviation activities occur closely together.

The other options do not align with this specific definition: While some airspace may extend up to 18,000 feet, that is characteristic of Class A airspace; Class B airspace is explicitly limited to the region around busy airports up to 10,000 feet. Similar confusions can arise regarding the heights of other classes, but Class B's parameters are specifically designed for proximity to high-traffic airports. Understanding the classification of airspace is crucial for pilots and air traffic controllers to ensure compliance and safety
