Why is the Lambert's Conformal Conic chart projection widely used for aeronautical charts in mid-latitudes?

1. A straight line drawn on the chart closely approximates a Great Circle route, and scale is relatively constant.
2. All Rhumb Lines appear as straight lines, making heading calculations simple.
3. It represents the entire Earth's surface on a single sheet without distortion near the poles.
4. It is a cylinder projection that keeps grid lines perfectly parallel at all latitudes.
