Which airspace is indicated by thick faded magenta lines indicating transitional airspace that extends down to 700 feet AGL?

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

Answer: (B)

The thick faded magenta lines show Class E that begins at 700 feet above the ground. This is transitional airspace where the floor is 700 AGL, so inside that area the airspace is Class E from 700 AGL up, while below 700 AGL it would typically be Class G if no other airspace class applies. This magenta shading is the chart symbol you’d look for to know that the airspace in that area isn’t Class G down to the surface, but becomes controlled starting at 700 AGL.

Other airspace types are drawn differently: Class B is shown with solid blue lines, Class C with solid magenta lines, and Class D with dashed blue lines. The magenta shading indicating a 700 AGL floor specifically points to Class E starting at 700 AGL, not the surface or a higher floor.
