Which of the following types of aeronautical charts is primarily used for VFR (Visual Flight Rules) navigation?

The choice that encompasses all the listed options, indicating that all types of aeronautical charts mentioned are primarily used for VFR navigation, emphasizes the variety of chart types available to pilots operating under Visual Flight Rules.

World Aeronautical Charts (WACs) provide a broad overview of large areas, featuring important landmarks and navigational aids. They are useful for general VFR navigation over extensive regions.

Sectional Charts are specifically designed for VFR navigation, presenting detailed topographical features, airspace classification, and other critical information for pilots flying visually. They cover smaller geographical areas more intensely than WACs, making them ideal for pilots flying at lower altitudes.

Terminal Area Charts are utilized around busy airport environments, providing crucial information for safe navigation in the vicinity of aerodromes. These charts are particularly useful for pilots during takeoff and landing, ensuring awareness of surrounding airspace and obstacles.

Given that all these chart types serve the purpose of supporting VFR navigation in various contexts—from wide-ranging regional navigation to specific terminal operations—the correct answer encapsulates the completeness of the available chart options.
