A blue segmented circle on a Sectional Chart depicts which class airspace?

• A. Class C
• B. Class D
• C. Class B
• D. Class A

Answer: (B)

A blue segmented circle shows Class D airspace. This surrounds airports that have an operating control tower and extends from the surface up to a ceiling typically 2,500 feet above the airport's elevation. You must establish two-way radio communication with ATC before entering and maintain it while inside. This differs from other airspace shown on Sectionals: Class B is a solid blue boundary, Class C is a solid magenta boundary, and Class A is IFR-only airspace not depicted on VFR Sectionals.
