The charts are published "in accordance with Interagency Air Cartographic Committee specifications and agreements, approved by the Department of Defense and the Federal Aviation Administration". The legend of an aeronautical chart lists many of the symbols, colors and codes used to convey information to the map reader.
FAA-Terminal Area Chart Baltimore-Washington from 2011. Like the VFR sectional charts that they complement, terminal area charts depict topographic features and other information of interest to aviators flying visually, including major landmarks, terrain elevations, visual navigation routes, ground-based navigation aids, airports, rivers, cities, and airspace boundaries.
The Airport/Facility Directory also provides a means for the FAA to communicate, in text form, updates to visual navigation charts between their revision dates — VFR Sectional and Terminal Area Charts are generally revised every six months. Volumes are side-bound at 5 + 3 ⁄ 8 by 8 + 1 ⁄ 4 inches (140 mm × 210 mm), and colored a ...
The first sectional chart was published in 1930; in 1937 the full series of the lower 48 states was completed. These early sectional charts were smaller (most covered two degrees of latitude and six of longitude) with the map on one side; after 1950 the legend and index to adjoining charts was on the reverse.
An aeronautical chart is a map designed to assist in the navigation of aircraft, much as nautical charts do for watercraft, or a roadmap does for drivers. Using these charts and other tools, pilots are able to determine their position, safe altitude, best route to a destination, navigation aids along the way, alternative landing areas in case of an in-flight emergency, and other useful ...
These charts are similar to sectional charts, and the symbols are the same. However, there is less detail at the smaller scale, so it is seldom used for visual flight rules flight at slower speeds or for local flights. WACs show topographic information, airports and radio navigational aids. They are useful for strategic flight planning, where a ...
In the US, the Federal Aviation Administration issues sectional charts. Each rectangular area covering one degree of latitude and one degree of longitude is divided into four smaller areas called quadrangles (in accordance with the World Geographic Reference System, or GEOREF), each spanning half a degree of latitude and half a degree of ...
It is believed that this extra awareness can improve planning and navigation. Hot spots are shown on both airport diagrams and chart supplements. [6] An area is likely to become a hot spot if it has: [7] hold short line infractions; approach hold issues; complex taxiway configurations; movement-non movement boundary area issues; tower line of ...
