Question 36
Domain 3: FAA Part 107 AirspaceOn a sectional chart, a remote pilot sees an area marked with blue vignette shading with the label "Class E" inside. What does this indicate?
Correct answer: B
Explanation
On sectional charts, blue vignette shading identifies Class E airspace that begins at 700 feet above ground level. The chart label "Class E" inside the shaded area shows the controlled airspace designation, and the blue tint indicates the floor is "700 feet AGL" rather than surface level.
Why each option is right or wrong
A. Class E airspace beginning at 14,500 feet MSL
B. Class E airspace beginning at 700 feet AGL
FAA sectional chart symbology uses a blue vignette to depict controlled airspace where the floor of Class E starts at 700 feet AGL; this is the standard depiction in FAA Chart User’s Guide and Aeronautical Chart legend materials. The “Class E” label inside the shaded area confirms the airspace class, and the blue shading specifically distinguishes it from magenta vignette areas that begin at 1,200 feet AGL.
C. Class E airspace beginning at the surface
D. Prohibited area
