Sectional Aeronautical Charts are primarily utilized for what purpose?

Sectional Aeronautical Charts are primarily utilized for pilotage, which refers to the navigation of an aircraft using visual references. These charts provide essential information such as topographical details, landmarks, airspace boundaries, and navigation aids, enabling pilots to safely navigate by sight. The use of pilotage is especially crucial for visual flight rules (VFR) operations, where pilots depend on visual cues from the environment rather than relying solely on instruments or air traffic control guidance.

While sectional charts do assist with navigation in general, their main strength lies in their ability to serve as visual aids, helping pilots identify geographical features and their relationship to the aircraft's flight path. This situational awareness is key for maintaining safe distances from terrain and avoiding obstacles during flight. Other options such as communication and weather forecasting do not fall under the main functions of sectional charts, as those aspects rely on different resources and tools specific to those purposes.
