What is the scale of the World Aeronautical Chart (WAC)?

The World Aeronautical Chart (WAC) is designed for navigational use at a broader scale, specifically providing important geographic and aeronautical information for pilots flying at lower altitudes. The correct scale for the WAC is 1:1,000,000. This means that one unit on the map represents one million of the same unit in the real world, making it particularly useful for general aviation and international flight planning.

The chosen scale allows for a comprehensive overview, making it easier for pilots to interpret airspace structure, navigational aids, airports, and terrain features without overwhelming detail. Understanding this scale is crucial for effective navigation and flight planning, as it provides a broader perspective compared to charts with larger scales that offer more detailed information but cover smaller geographic areas.
