What is true about the RVR measurement?

• A. It indicates ground visibility only
• B. It is only relevant for IFR operations
• C. It is used for both VFR and IFR operations
• D. It is only reported in statute miles

Answer: (B)

The correct answer highlights the relevance of Runway Visual Range (RVR) specifically for Instrument Flight Rules (IFR) operations. RVR is a measurement used primarily to assess visibility on runways, especially under conditions where pilots might be flying in low visibility, such as during fog or heavy precipitation. In IFR operations, pilots rely on accurate RVR readings to make informed decisions about whether it is safe to take off or land. Since IFR procedures are conducted in conditions where visibility might not meet the requirements for Visual Flight Rules (VFR), the RVR offers a crucial metric that helps determine operational safety. Therefore, RVR is particularly influential and necessary in IFR scenarios since it directly correlates to the minimum visibility standards required for safe flight operations. While RVR can provide insight into visibility conditions, it is not solely indicative of ground visibility in general, nor is it exclusively relevant to IFR operations, as it does play a role in VFR under certain conditions. It is also reported in meters, in addition to statute miles, making the notion that it is only reported in statute miles incorrect.
