Lambert conformal conic projection

A Lambert conformal conic projection (LCC) is a conic map projection, which is often used for aeronautical charts. In Mathematics, a conic section (or just conic) is a Curve obtained by intersecting a cone (more precisely a circular Conical surface A map projection is any method of representing the Surface of a sphere or other shape on a plane. An aeronautical chart is a Map designed to assist in Navigation of Aircraft, much as Nautical charts do for watercraft or a roadmap In essence, the projection superimposes a cone over the sphere of the Earth, with two reference parallels secant to the globe and intersecting it. A cone is a three-dimensional Geometric shape that tapers smoothly from a flat round base to a point called the apex or vertex A circle of latitude, on the Earth, is an imaginary East - West circle connecting all locations (not taking into account elevation that share a given A secant line of a Curve is a line that (locally intersects two points on the curve This minimizes distortion from projecting a three dimensional surface to a two-dimensional surface. Distortion is least along the standard parallels, and increases further from the chosen parallels. As the name indicates, maps using this projection are conformal. In Mathematics, a conformal map is a function which preserves Angles In the most common case the function is between domains in the Complex plane

Pilots favor these charts because a straight line drawn on a Lambert conformal conic projection approximates a great-circle route between endpoints. A great circle is a Circle on the surface of a Sphere that has the same circumference as the sphere dividing the sphere into two equal Hemispheres.
