FAA World Aeronautical Chart, showing the northern part of theA World Aeronautical Chart (WAC) is a type of used for navigation by of moderate speed aircraft and aircraft at high altitudes. They are at a of 1:1,000,000 (about 1 inch = 13.7 nautical miles or 16 statute miles).These charts are similar to, and the symbols are the same. However, there is less detail at the smaller scale, so it is seldom used for flight at slower speeds or for local flights.
Aeronautical Charts are used by pilots for flight planning and navigation. With these charts and other tools, pilots can determine their position, safe altitude, best route, navigational aids, emergency landing areas, and other useful information, such as radio frequencies and airspace boundaries. VFR Sectional Aeronautical Charts are the primary navigational reference medium used by VFR pilots in the US. The 1:500,000 scale Sectional Aeronautical Chart Series is designed for visual navigation of slow to medium speed aircraft.

WACs show information, airports and radio. They are useful for strategic flight planning, where a view of the entire flight area is useful.These charts are revised annually, except for several charts and the / charts which are revised every 2 years. WAC charts are amended every 3 to 5 years. On June 25, 2015, the USA's Federal Aviation Administration announced the discontinuation of all WACs covering the USA.A set of 12 WACs covered the continental United States and 8 others covered Alaska. Airspace is covered by a set of 18 WACs. The 43 Australian WACs are indexed according to a geographic name or a corresponding 4-digit number.Unlike sectional charts, North American WACs are named according to an international 'grid system' having a combination of letters and numbers. For example, WAC CF-16 covered the, and E-15 covers the area.
Letters progress from A at the to U at the southern tip of. The numbers generally progress from 1 at the and increasing to the east, to a maximum of 29, depending upon the number of charts required at that.See also.
