What is the primary role of World Aeronautical Charts (WAC)?

World Aeronautical Charts (WAC) are primarily designed to assist with flight planning and in-flight navigation, particularly for cross-country flights. They offer a comprehensive overview of geographic and aeronautical information, including terrain features, navigation aids, airspace boundaries, and airports. This makes them invaluable for pilots who are navigating long distances and need to understand the airspace and the geography of the areas they are flying over.

These charts are specifically oriented towards visual flight rules (VFR) pilots operating at lower altitudes, providing the necessary details for maintaining situational awareness and ensuring safety during the flight. Pilots using WACs can effectively plan routes, identify visual landmarks, and navigate through varied terrain, all critical components for successful cross-country operations.
