Which section defines general airspace structure?

Which section defines general airspace structure?

• A. ENR 2
• B. ENR 1.4
• C. GEN 3.3
• D. ENR 5.4

Answer: (A)

Understanding where the en-route airspace is described helps you quickly locate information for flight planning. In the Aeronautical Information Publication, the ENR part contains en-route and airspace information, and the portion that covers general airspace structure lays out how the airspace is organized—the overall layout, the boundaries of controlled airspace, the network of airways, and how different airspace blocks fit together. This focus makes it the best source for questions about the general structure of airspace, rather than sections that cover general information (GEN) or more specific route or procedure details within ENR. So, the section that defines general airspace structure is the ENR part that describes en-route airspace organization.
