ENR 2 covers which topic?

ENR 2 covers which topic?

• A. General airspace structure
• B. Air navigation obstacles
• C. MORA
• D. Communications frequencies

Answer: (A)

This question tests understanding of what ENR 2 covers in the En Route part of the Aeronautical Information Publication. ENR 2 deals with the general airspace structure you’ll encounter while flying en route: how airspace is organized, the different types and classes of airspace, and the horizontal and vertical limits that define where you can operate and what ATC responsibilities apply. This framework is essential for planning routes and ensuring you stay clear of restricted or controlled areas. Air navigation obstacles are publication details about obstacles and terrain and are handled in other sections. MORA relates to minimum off-route altitudes for obstacle clearance and is a topic tied to safe altitude planning rather than the broad structure of airspace. Communications frequencies cover how to contact ATC and navigational facilities, which is also addressed in other parts of the AIP. Therefore, the best match for ENR 2 is the general airspace structure.
