Which document defines minimum runway widths and lengths, clear zones, frangibility areas, and approach/departure clearance surfaces?

• A. FAA Advisory Circular
• B. MIL-STD-810
• C. ISO 9001
• D. UFC 3-260-01

Answer: (D)

These design parameters for airfields are set by military facilities standards, not civil aviation guidance. Unified Facilities Criteria, specifically UFC 3-260-01, codifies the DoD’s airfield design requirements, detailing runway widths and lengths, safety zones such as clear zones and frangibility areas, and the approach/departure clearance surfaces. It provides the uniform criteria the military uses to ensure safe and compatible operations across services. The other options don’t fit this use: a FAA Advisory Circular governs civil airports, MIL-STD-810 covers environmental testing of equipment, and ISO 9001 is about quality management systems, not airfield geometry or safety surfaces.
