What is the floor and ceiling of Class B airspace?

Class B airspace typically extends from the surface up to 10,000 feet Mean Sea Level (MSL). This specific structure is designed to manage air traffic around busy airports, allowing for safe and efficient handling of multiple aircraft in and out of major terminal areas.

Class B airspace typically consists of a solid blue line depiction on sectional charts, indicating the boundaries that pilots must adhere to when flying within or near these areas. The dimensions of Class B airspace can vary, as each airport may have different requirements based on traffic volume and other operational factors, but the standard ceiling is consistently capped at 10,000 feet MSL.

In the options provided, others reflect incorrect altitudes or boundaries that do not accurately define the characteristics of Class B airspace, reinforcing why the correct answer is relevant to understanding airspace regulations and operational limitations for commercial pilots.
