Definition
A small-scale aeronautical chart, drawn at 1:1,000,000, that depicts large areas of terrain in moderate detail and is intended for use by pilots of moderate-speed aircraft and aircraft operating at higher altitudes. It shows cities, towns, principal roads, railroads, distinctive landmarks, drainage, terrain relief, airports, radio aids to navigation, special-use airspace, and obstructions.
Plain English
A flying map covering a wide area at a smaller scale than the more detailed Sectional Chart. It shows less fine detail but lets you see more of the country on one sheet, which suits faster aircraft and longer flights.
Context Anchor
Seen in aeronautical chart discussions and long-distance visual flight planning, especially when choosing which chart scale fits the route.
Derivation
The name reflects its purpose: a chart designed for aeronautical use that covers a broader portion of the world per sheet than the more detailed Sectional Chart. The 1:1,000,000 scale was originally adopted internationally so that adjacent charts from different countries would fit together.
Why Pilots Care
Provides an overview for high-altitude VFR navigation where sectional charts would require too many sheets.
Intuition Check
“World” does not mean one chart shows the entire world. Here it means a wide-area aviation chart series made for broad visual navigation.
Example Sentence 1
For the long cross-country to the coast, she planned with a World Aeronautical Chart so the whole route fit on a single sheet.
Example Sentence 2
At cruising altitude the World Aeronautical Chart gave enough detail to stay oriented without switching between multiple sectionals.
