RVV is associated with which aviation measurement?

• A. Runway visibility value
• B. Runway Visual Range
• C. Radar visibility value
• D. Relative visibility value

Answer: (A)

The concept here is runway-specific visibility. RVV is tied to Runway Visual Range—the distance over which a pilot on the runway centerline can clearly see the runway environment, including lights and markings. This measurement is obtained with instruments along the runway (like transmissometers) and is reported in METARs as Runway Visual Range. It’s different from general visibility because it focuses on how far you can see along the runway for landing and takeoff, which is critical for safe operations in low visibility.

The other terms aren’t standard runway-specific measurements. General visibility or radar-based visibility aren’t used to describe the distance along the runway, and “relative visibility value” isn’t a recognized aviation term for this purpose.
