What is the purpose of a sectional chart in aviation?

A sectional chart serves a crucial role in aviation by providing detailed aeronautical information that is essential for pilots. This includes valuable data such as the layout of airspace, navigation aids (like VORs and NDBs), airport locations, and terrain features. These charts are designed specifically to assist pilots during visual flight rules (VFR) operations by highlighting information that is vital for safe navigation and situational awareness.

The other options focus on aspects that sectional charts do not encompass. Passenger information is usually found in materials separate from navigational charts; meteorological data is provided through different sources, typically weather briefings and reports; and while emergency procedures for pilots are critical, they are documented separately, often in pilot operating handbooks or safety manuals rather than on sectional charts. Thus, the primary purpose of a sectional chart is to furnish comprehensive aeronautical information necessary for effective flight planning and navigation.
