What is the standard altitude for Class B airspace?

The standard altitude for Class B airspace typically extends from the surface up to 10,000 feet mean sea level (MSL). Class B airspace is designed to protect aircraft operating in busy airport environments, typically near major metropolitan areas where high-density traffic can pose a risk to safety. The lower limit being the surface allows for takeoff and landing operations, while the upper limit at 10,000 feet ensures that there is sufficient vertical separation from Class C, D airspace, and the general airspace above.

Understanding the structure of Class B airspace is crucial for pilots and air traffic controllers alike to ensure safe and efficient operations. The altitude limit of 10,000 feet MSL is also consistent with the operational requirements for managing the significant number of passenger and cargo flights that frequent these corridors.
