Does RVR take precedence over other visibility reports for the runway?

The correct answer indicates that Runway Visual Range (RVR) takes precedence over other visibility reports for a runway. RVR is a specific measurement of the distance one can see down the runway and is particularly critical for pilots during landing and takeoff, especially in low-visibility conditions such as fog, rain, or snow. This measurement provides an objective assessment of visibility that is directly related to runway conditions and is vital for safe flight operations.

When RVR is reported, it offers more precise information about the ability to see the runway ahead, which is crucial for making decisions regarding landing and departure. Other visibility reports, such as those provided by surface weather observations, can be influenced by factors that are not directly related to the actual visibility a pilot may experience when approaching or departing from the runway. Therefore, when RVR is available, it is considered the most reliable indicator of visibility for that specific runway and should be used as the primary reference for pilots.

The options that suggest limitations, such as only during poor weather or for departures, do not capture the comprehensive nature of RVR's applicability in aviation safety. RVR is essential in all conditions where visibility is a concern, making it the gold standard for runway visibility reporting.
