When vectored for an approach with an RVR of 2400 and the reported range 1500 to 3000, which RVR value should be used to determine acceptability for the approach?

When vectored for an approach with an RVR of 2400 and the reported range 1500 to 3000, which RVR value should be used to determine acceptability for the approach?

• A. 2400
• B. 1500
• C. 3000
• D. 0

Answer: (A)

RVR used to determine if an approach is acceptable is the value that applies to the approach itself, not the range of readings reported for the field. When you’re vectored for an approach, rely on the RVR specific to that approach (the value in effect for the approach or its minima). Here, the RVR associated with the approach is 2400, which is the controlling visibility for decision-making. The reported range of 1500 to 3000 simply shows variability along the field; it does not override the approach’s designated RVR. The value 0 is not a valid decision value. So, use 2400 because it’s the RVR that governs acceptability for this approach.
