sectional aeronautical charts

Charts that are designed for visual navigation of slow-to medium-speed aircraft. The topographic information consists of contour lines, shaded relief, drainage patterns, and an extensive selection of visual checkpoints and landmarks used for flight under VFR (visual flight rules). Cultural features charted include cities and towns, roads, railroads, and other distinct landmarks. The aeronautical information includes visual and radio aids to navigation, airports, controlled airspace, special-use airspace, obstructions, and related data. The scale is 1 in = 6.86 NM/1:500,000. 60 × 20 in is folded to 5 × 10 in. The Lambert conformal projection is used to create the chart, so straight lines drawn on the chart are nearly great-circle routes. (see page 571)
