Which color is used to depict Class C airspace on sectional charts?

In sectional charts, Class C airspace is depicted using solid magenta lines. This visual representation indicates the boundaries of Class C airspace, which generally surrounds major airports with a significant volume of traffic. The use of solid magenta for Class C is a standardized convention in aeronautical charts that helps pilots easily identify areas of controlled airspace, which require specific communication and operating procedures. This color coding is essential for situational awareness and ensuring compliance with airspace rules, contributing to the safety and efficiency of flight operations.

Other airspace classes are represented by different colors or line styles; for example, Class B airspace uses solid blue, while Class D airspace is indicated by dashed blue. By familiarizing themselves with these standard representations, pilots can effectively navigate and conduct their flight operations within the complex airspace system.
