Aeronautical chart on Lambert conformal conic projection with standard parallels at 33°N and 45°N. A Lambert conformal conic projection (LCC) is a conic map projection used for aeronautical charts, portions of the State Plane Coordinate System, and many national and regional mapping systems.

Usually clipped near 80°N/S. Standard world projection of the NGS in 1922–1988. c. 150: Equidistant conic = simple conic: Conic Equidistant Based on Ptolemy's 1st Projection Distances along meridians are conserved, as is distance along one or two standard parallels.

A sectional chart is a two-sided chart created from a Lambert Conformal Conic Projection [1] with two defined standard parallels. The scale is 1:500,000, with a contour interval of 500 feet. The size of each sectional is designed to be "arm's width" when completely unfolded.

In cartography, a conformal map projection is one in which every angle between two curves that cross each other on Earth (a sphere or an ellipsoid) is preserved in the image of the projection; that is, the projection is a conformal map in the mathematical sense. For example, if two roads cross each other at a 39° angle, their images on a map ...
Conformal projections are generally preferred. Common map projections include the transverse Mercator (used in Universal Transverse Mercator, the British National Grid, the State Plane Coordinate System for some states), Lambert conformal conic (some states in the SPCS), and Mercator (Swiss coordinate system).
There are several projections used in maps carrying the name of Johann Heinrich Lambert: Lambert cylindrical equal-area projection (preserves areas) Lambert azimuthal equal-area projection (preserves areas) Lambert conformal conic projection (preserves angles, commonly used in aviation navigation maps) Lambert equal-area conic projection ...
