Sectional charts are aeronautical maps designed for navigation under visual flight rules. They show topographical features and terrain elevations, as well as ground features such as airports, highways, buildings and obstructions. Charts also show information on airspace classes, radio frequencies, navigation routes and way points.
The Seattle Aeronautical Chart Mask is made with 2 layers of cotton and an outer layer of polyester, elastic looped.
