On a sectional chart, the floor of Class E airspace is 700 feet AGL when it lies within which depiction?

• A. within the fuzzy magenta vignette
• B. within the solid blue contour
• C. near the airport symbol
• D. within the shaded magenta area

Answer: (A)

The key idea is how sectional charts show where Class E begins at 700 feet above ground level. That base is depicted by a fuzzy magenta vignette around certain areas. When you’re inside this magenta fuzzy shading, the floor of Class E is 700 feet AGL; below that, the airspace is Class G. This is why the correct depiction is the fuzzy magenta vignette. The other options correspond to different chart symbols or features (solid blue lines for other airspace boundaries, proximity to the airport symbol not by itself indicating the base, and a magenta shading type that represents something else), but they do not indicate the 700 AGL floor.
