The purpose of the Aerodrome Standards and Recommended Practices is to serve as the ______ for airport specifications.

• A. Authoritative reference
• B. Physical characteristics
• C. Obstacle limitation surfaces
• D. Lighting, markers, marking, and signs

Answer: (A)

Standards and Recommended Practices provide an authoritative reference for airport specifications. They establish the official rules and minimum requirements used by regulators and airport designers to shape how aerodromes are built, certified, and operated, ensuring consistency and safety across airports worldwide. They describe the criteria and guidance that airports must meet, rather than being a physical feature or a single element like obstacle limitation surfaces or lighting. Those components are elements described within the standards, but the overarching purpose is to serve as the recognized, binding reference for how airport specifications are set.
