Which CFR part covers airspace, routes, and reporting points?

The correct answer is Part 71, which specifically addresses the classification of airspace and the establishment of routes and reporting points within those airspaces. This regulation details the different types of airspace classifications—such as Class A, Class B, Class C, Class D, and Class E—and provides guidelines for their structure and operational parameters. It also governs the designation of specific routes, including airways, and reporting points that are crucial for pilots in navigating airspace and maintaining situational awareness.

This part is essential for both controllers and pilots to understand airspace boundaries, communication requirements, and navigation procedures, ensuring safe and efficient operation in the National Airspace System (NAS).

Other parts mentioned, such as Parts 61 and 91, cover pilot certification and general operating and flight rules, respectively, while Part 97 focuses on instrument approach procedures. While these regulations are important for different aspects of aviation, they do not specifically cover the classification and management of airspace, routes, and reporting points like Part 71 does.
