Which projection is conformal and used for navigation?

Conformality means angles are preserved locally, so small shapes and directions stay true on the map. The Lambert conformal conic projection is built to be conformal, using two standard parallels so that distortion is minimized along those lines. Because angles are preserved, bearings and course lines plotted on the chart remain reliable, which is exactly what navigators need. This combination—local angle accuracy and a practical conic form for mid-latitude regions—makes Lambert conformal a strong, commonly used choice for navigation charts. (Mercator also preserves angles and is widely used for navigation, especially at sea, while Polyconic is not conformal and Transverse Mercator serves different mapping needs.)
