Which statement accurately describes Fixed-Wing Taxiway Dimensions?

• A. 75 ft wide, taxiway lateral clearing zone is 200 feet from centerline, 25 ft paved shoulder, 50 ft paved shoulder for a B-52, 10 ft paved shoulder for fighters
• B. 60 ft wide, lateral clearance 150 ft, shoulder 20 ft for all aircraft
• C. 100 ft wide, lateral clearing zone 300 ft, shoulder 30 ft
• D. 40 ft wide, no shoulder requirement

Answer: (A)

The main idea here is how fixed‑wing taxiway dimensions are set to match what aircraft need: width to accommodate the aircraft plus clearance for wings and tires, a safe lateral space to keep objects and other traffic away from the taxi path, and shoulder widths that protect the pavement and provide room for wingtip or tire overhang if needed. The best option uses a practical, versatile set of dimensions: a 75‑ft wide taxiway, a substantial lateral clearing zone of 200 ft from the centerline to keep obstacles out of the taxiway path, and paved shoulders that vary by aircraft type—25 ft standard, 50 ft for a heavy airframe like a B‑52, and 10 ft for fighters. This combination covers typical operations for a wide range of fixed‑wing aircraft, balancing safety, compatibility, and pavement protection. The other choices either use narrower widths or insufficient/absent shoulders, which would not adequately accommodate larger aircraft or provide the necessary edge protection and clearance.
