Class G airspace is depicted in what shading where it exists above 18,000 MSL?

• A. Brown
• B. Yellow
• C. Gray
• D. Blue

Answer: (A)

Class G airspace, which is uncontrolled airspace, is depicted in brown shading on sectional charts for areas that exist above 18,000 feet Mean Sea Level (MSL). This is consistent with federal regulations and charting standards used in aviation. The choice of brown for Class G airspace helps distinguish it from other airspaces displayed on charts, such as Class E, which generally appears in a different color. Understanding these color codes is essential for pilots and air traffic controllers to effectively navigate and communicate within varying airspaces. The other colors designated for other classes of airspace serve specific purposes. For instance, chart shading for Class E airspace (which usually starts at 1,200 feet MSL or above) is often depicted in a different color to aid in visual identification. Knowing these distinctions is crucial for safe and efficient airspace management.
