Which statement is true about RVR data when RVR equipment is inoperative and visibility is at or below 1 mile?

Which statement is true about RVR data when RVR equipment is inoperative and visibility is at or below 1 mile?

• A. RVR should be reported using data from the alternate end
• B. RVR should not be reported at all
• C. RVR should be reported locally and longline as RVRNO
• D. RVR should be reported only in longline format

Answer: (C)

When RVR equipment is inoperative, you must clearly indicate that RVR data is not available and share that status through all dissemination channels. If visibility is at or below one mile, the correct approach is to report locally and on the longline that RVR data is not available, using the code RVRNO. This provides unambiguous, consistent information to pilots across both local broadcasts and the longline feed, preventing reliance on any faulty readings. Using data from the opposite end would imply the failed sensor is still giving readings, which isn’t accurate. Not reporting at all would leave pilots without essential information, and reporting only on one channel wouldn’t ensure all users receive the notice.
