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.
The size of each sectional is designed to be "arm's width" when completely unfolded. The "northern" half of the section is on one side of the chart, and the "southern" on the reverse. The edges between north and south are designed with a calibrated overlap that permits plotting extensions of course lines from one side to the other, once the ...
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 ...
MEF's of 4700 and 3300 feet are shown on this excerpt from the FAA's Los Angeles sectional aeronautical chart. Maximum elevation figure ( MEF ) is a type of visual flight rule (VFR) information that indicates the elevation of the highest geographical feature within a GEOREF quadrangle area.

TikTok and ByteDance on Monday had filed the emergency motion with the U.S. Court of Appeals for the District of Columbia, asking for more time to make their case to the U.S. Supreme Court.
U.S. applications for unemployment benefits jumped to their highest level in two months last week but remain low relative to historical standards. Jobless claim applications climbed by 17,000 to ...
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 ...
