![]() VFR Terminal area charts are designed with a scale and coverage appropriate for a large airport’s general surroundings (1:250,000).Ĭontrolled airspace is classified into 5 classesĬlass A: exists between 18,000 and 60,000 feet in altitude.These charts are updated every six months. Not only those but also airspace classifications, ground-based navigation aids, radio frequencies, longitude and latitude, navigation waypoints, and navigation routes are displayed on the sectional charts. It shows topographical elements (such as terrain levels), ground features (such as rivers, dams, bridges, and buildings), and other ground objects that pilots may find useful (airports, beacons, landmarks, etc.). It is aimed to be used in visual flight rules air navigation (VFR). They cover a total area of around 340×340 miles. Sectional charts are printed on both sides of the map and have a scale of 1:500,000.These charts are updated annually, except for a few Alaskan charts and the Mexican/Caribbean charts, which are updated every two years. They’re useful for strategic flight planning, as they provide you with a bird’s-eye view of the whole flight region. It displays topographic information, airports, and radio navigational aids. However, because of the smaller scale, it has less information. These graphs are similar to sectional graphs and use the same symbols. They have a scale of 1:1,000,000 and cover a huge area. World Aeronautical Charts (WACs) are a form of aeronautical charts used for navigation by pilots of medium-speed aircraft and aircraft flying at high altitudes. ![]() ![]() Visual charts are classified according to their scale which is directly proportional to the size of the area covered by one map.
