What is the main role of a sectional aeronautical chart?

The main role of a sectional aeronautical chart is to aid in navigation and situational awareness. These charts are specifically designed to provide a comprehensive overview of the airspace, terrain, and various navigational aids, making them essential tools for pilots during flight. They depict features such as airways, navigation aids, obstructions, and different airspace classifications, which help pilots make informed decisions during their flight operations.

While other charts and resources might focus on specific aspects like elevation information or airport facilities, sectional charts integrate multiple factors into a single resource that enhances a pilot's ability to navigate efficiently and safely. They allow pilots to maintain situational awareness by visually representing critical information, which is vital for successful flight planning and execution.
