Which 14 CFR part designates Class A, B, C, D, and E Airspace Areas; Air Traffic Service Routes; and Reporting Points?

• A. 14 CFR Part 71
• B. 14 CFR Part 73
• C. 14 CFR Part 91
• D. 14 CFR Part 97

Answer: (A)

The key idea here is understanding who sets how airspace is organized and where routes and reporting points live in the regulations. 14 CFR Part 71 designates the Class A, B, C, D, and E airspace areas, the air traffic service routes that connect them, and the reporting points pilots use to indicate position. In other words, Part 71 lays out the boundaries of controlled airspace, the routes ATC uses to provide separation, and the reporting points used for communication and navigation procedures. Knowing this helps you determine where you need ATC clearance, what airspace rules apply, and where to report your position as you fly.

For contrast, Part 73 covers special-use airspace like restricted or prohibited areas; Part 91 covers general operating and flight rules; Part 97 covers standards for instrument approach procedures.
