What would you do if the RVR equipment were out of service but visibility was still being reported?

In the scenario where the RVR (Runway Visual Range) equipment is out of service but visibility is being reported, the correct action is to declare RVR unavailable in the remarks section. This indicates to pilots and other users of the weather information that the standard RVR information cannot be provided due to equipment issues, which is crucial for safety.

Reporting RVR values without functioning equipment can lead to misinformation; estimated values may not accurately reflect the conditions, and omitting RVR altogether could cause confusion about what information is available. Declaring it as unavailable maintains clarity and informs all parties that the RVR data cannot be relied upon at that time, thereby ensuring better situational awareness for those utilizing the information for flight planning and operations.
