What type of map displays rhumb lines and is used for air navigation?

The Transverse Mercator Projection is widely used in air navigation because it accurately represents rhumb lines or loxodromes. These lines are crucial for pilots since they indicate a constant compass heading over the globe, which is essential for maintaining a steady course while navigating. The projection preserves angles, making it effective for navigation over small areas, which is beneficial for pilots when they need to calculate headings, distances, and waypoints.

The other projections mentioned have different characteristics. For instance, the Lambert Conformal Conic is excellent for areas with a predominant east-west orientation but doesn't specifically display rhumb lines in the same straightforward manner as the Transverse Mercator. The Universal Transverse Mercator is a standard for dividing the world into zones for mapping purposes, but it is not specifically focused on the representation of rhumb lines. The Polar Stereographic is primarily used for polar regions and does not cater to air navigation needs across broader and more varied latitudes. Thus, the Transverse Mercator Projection stands out as the most appropriate choice for displaying rhumb lines in aviation contexts.
