What is the function of the VNC charts in aviation?

VNC charts, or Visual Navigation Charts, are designed specifically for visual navigation in general aviation. Their primary function is to provide pilots with terrain information, which is crucial for maintaining situational awareness and safe flight at low altitudes. VNC charts display a variety of features, including topography, prominent landmarks, and navigational aids, which assist pilots in navigating visually and avoiding obstacles, especially in mountainous or complex terrain.

In contrast, IFR navigation relies on different types of charts, such as en route charts and approach plates, which contain specific information necessary for instrument flying. Detailed airport information is typically found on airport diagrams or in sectional charts rather than VNC charts. While airspace restrictions are depicted on various aviation charts, VNC charts primarily emphasize visual navigation and help pilots understand the terrain features in their flying area.
