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.
This article describes the graphic conventions used in Sectional charts and Terminal area charts published for aeronautical navigation under Visual Flight Rules in the United States of America. The charts are published "in accordance with Interagency Air Cartographic Committee specifications and agreements, approved by the Department of Defense ...
Sectional charts typically cover a total area of about 340x340 miles, printed on both sides of the map. The scale is 1:500,000. VFR terminal area charts are created with a scale and coverage appropriate for the general vicinity of a large airport (1:250,000). They may depict preferred VFR flight routes within areas of congested airspace.
The sectionals are complemented by terminal area charts (TACs) at 1:250,000 scale for the areas around major U.S. airports, and until 2016 by World Aeronautical Charts (WACs) at a scale of 1:1,000,000 for pilots of slower aircraft and aircraft at high altitude. [1] Since February 2021, the charts have been updated on a 56-day publication cycle. [2]
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 ...
In aviation, a terminal control area (TMA, or TCA in the U.S. and Canada), [1] [2] [3] is a designated area of controlled airspace surrounding a major airport where there is a high volume of traffic.
Such areas are established for security or other reasons associated with the national welfare. These areas are published in the Federal Register and are depicted on aeronautical charts." Part of a terminal area chart, showing the prohibited/restricted airspace surrounding Camp David. Some prohibited airspace may be supplemented via NOTAMs.
Pilots use aeronautical charts based on LCC because a straight line drawn on a Lambert conformal conic projection approximates a great-circle route between endpoints for typical flight distances. The US systems of VFR (visual flight rules) sectional charts and terminal area charts are drafted on the LCC with standard parallels at 33°N and 45 ...
