Sectional chart
From Wikipedia, the free encyclopedia
In United States aviation, a sectional chart is a type of aeronautical chart designed for navigation under Visual Flight Rules.
[edit] Overview
A sectional chart provides detailed information on topographical features that are important to aviators, such as terrain elevations, ground features easily identifiable from altitude (rivers, dams, bridges, large buildings, etc.), and ground features useful to pilots (airports, beacons, distinctive landmarks, etc.). The chart also provides information on airspace classes, ground-based navigation aids, radio frequencies, longitude and latitude, naviation waypoints, navigation routes.
Sectional Charts are in 1:500,000 scale. The Federal Aviation Administration in the United States provides a series of over 50 charts covering the continental United States, Alaska, and Hawaii. A number of commercial enterprises, notably Jeppesen, produce compatible, certified Sectionals.
The Sectionals are complemented by Terminal Area Charts (TACs), produced in 1:250,000 scale and depicting the areas around major U.S. airports in detail.
Sectional Charts are updated at regular six-month intervals.
