An aeronautical chart serves the primary purpose of providing navigational information essential for flight planning. These charts include critical data such as airways, navigational aids, terrain features, airspace boundaries, and altitude information, all designed to facilitate safe and efficient navigation by pilots. By utilizing an aeronautical chart, pilots can plan their routes, identify potential hazards, and understand airspace restrictions, ensuring they operate within regulatory requirements and maintain safety during flight operations.

While airline routes, weather updates, and lists of airports may be relevant to aviation, they are not the primary functions of aeronautical charts. Airline routes can be depicted on certain types of charts, but these do not encompass the full range of navigational information contained in an aeronautical chart. Likewise, while weather is crucial for flight planning, updates are typically provided through other means, like weather briefings or specialized weather services. Airports are often indicated on aeronautical charts, but the charts themselves are more focused on navigation than providing a complete list of airports. Hence, the correct choice emphasizes the vital role aeronautical charts play in ensuring effective flight navigation and planning.
