Which chart represents a scale of 1: 500,000?

The correct answer is the Visual Navigational Chart (VNC). VNCs are specifically designed for visual navigation, primarily used by pilots flying under visual flight rules (VFR). They provide detailed information about airspaces, landmarks, and navigational aids, which are essential for pilots to safely navigate during flight. The scale of 1:500,000 allows for a broad view of geographic features and navigation resources, making it suitable for visual navigation over larger distances.

Other types of charts, such as the Visual Terminal Chart (VTC), World Aeronautical Chart (WAC), and Medium Aeronautical Chart (MAC), serve different purposes and scales. VTCs are aimed primarily at terminal areas with a scale of 1:250,000 or larger for more detailed information. WACs have a scale of 1:1,000,000, focusing on broader areas, while MACs typically have a scale of 1:500,000 but are used less commonly. Understanding the scale and purpose of each chart type is crucial for pilots to select the most appropriate chart for their navigation needs.
