What RVR values should be issued when either is less than 2000 feet?

• A. Touchdown and rollout RVR
• B. Midpoint and rollout RVR
• C. Midpoint and touchdown RVR
• D. Touchdown and approach RVR

Answer: (C)

When either RVR (Runway Visual Range) measurement is less than 2000 feet, it is crucial to provide both the midpoint and touchdown RVR values. This is because the midpoint RVR indicates the visibility conditions at a point halfway down the runway, which is important for pilots during approaches and landings. The touchdown RVR provides information on the visibility conditions where the aircraft first makes contact with the runway. Providing both values helps ensure that pilots receive comprehensive information about visibility conditions throughout the critical phases of landing. If only one RVR value were provided, it could lead to insufficient situational awareness for pilots, impacting safety during low visibility operations. Thus, issuing both midpoint and touchdown RVR ensures that pilots are well-informed and can make informed decisions regarding their approach and landing under such conditions.
