Which statement about Class B airspace is true?

• A. It is a single uniform shape.
• B. It is individually tailored with a surface area and two or more layers.
• C. It does not require ATC clearance.
• D. It only surrounds general aviation airports.

Answer: (B)

Class B airspace is designed around busy airports with a customized, multi-layer structure rather than a single, uniform volume. It is built as a surface area surrounding the primary airport and several higher shelves above it, each with its own floor altitude. This tailored, layered arrangement allows ATC to manage high volumes of traffic by controlling access and sequencing as aircraft move through different levels. The statement describes exactly this structure, making it the correct description. A single uniform shape wouldn’t reflect how Class B is actually configured. Also, Class B requires ATC clearance to enter and typically surrounds major airports, not only general aviation ones.
