What is the altitude range for Class B airspace?

Class B airspace typically extends from the surface up to an altitude of 10,000 feet MSL (Mean Sea Level). This type of controlled airspace surrounds major airports to ensure the safety and efficiency of air traffic, particularly because it accommodates a high volume of commercial and private flights. The design of Class B airspace is to protect arriving and departing aircraft, necessitating that pilots operating within this airspace are equipped with a specific level of training and communication capabilities for safe operation.

The rules governing Class B airspace require pilots to receive clearance from Air Traffic Control before entering, emphasizing the importance of maintaining organized and safe traffic flow. This range from surface to 10,000 feet reflects the operational altitude where most commercial and high-demand aircraft operate around these busy airports.
