What is a Sectional Aeronautical Chart?
- The majority of VFR pilots utilize sectional aeronautical charts as their primary source of navigational information. The 1:500,000 scale Sectional Aeronautical Chart Series is intended for slow- to medium-speed aircraft visual navigation. The relief and a selective number of visual checkpoints utilized for flight under visual aviation rules make up the topographic information provided.
- The display height of the earth's surface using the relief and elevation contour lines completes the appearance of topographic data.
- Settlements, cities, rivers, highways, railroads, high peaks, and other notable locations are all readily visible observation spots.
- Population centres, drainage systems, roadways, railroads, and other recognizable landmarks are among the checkpoints. Airports, controlled airspace, restricted zones, impediments, and associated information are among the aeronautical details on sectional charts. Every 56 days, these charts are refreshed.
