“An aeronautical chart where the earth’s features are represented with a minimum of distortion.” → CORRECT. A topographical chart, like a Sectional Aeronautical chart, is designed to allow Pilots to navigate by visual reference to the ground.

To achieve this effectively, the chart must represent the ground physical features, such as mountains, rivers, lakes, cities, as accurately as possible, in terms of their relative shape and position.

Most aeronautical topographical charts use a Lambert Conformal Conic projection, which ensures that small shapes are preserved and angles are correct, leading to a minimum distortion for the features depicted.

Regarding the other options:

“An aeronautical chart where parallels of latitude are parallel straight lines.” → INCORRECT. It is a characteristic of a Direct Mercator chart projection, but not a requirement for a topographical chart which uses Lambert Conformal Conic projection, where parallels are curved.

“An aeronautical chart where scale of the chart is constant throughout the chart.” → INCORRECT. It is impossible for a chart to have a constant scale, because the chart is flat and depicts the ellipsoid Earth.

“An aeronautical chart where meridians are parallel straight lines.” → INCORRECT. It is a characteristic of a Direct Mercator chart projection.
