During low visibility, what range is the RVR specifically defined as?

The RVR, or Runway Visual Range, is a measurement used to assess visibility conditions specifically for aircraft operations. During low visibility situations, the RVR is defined as being between 1200 feet and 600 feet. This range indicates critical conditions where visibility is significantly reduced, impacting both taxiing and flight operations.

Recognizing the implications of the RVR range is important for ensuring safe operations at airports, as it dictates the visibility standards below which specific procedures must be followed. Understanding these parameters helps pilots and ground personnel take the necessary precautions and actions to maintain safety standards during low-visibility conditions.

In contrast, other ranges presented do not accurately reflect the definition of RVR during low visibility, which focuses primarily on the threshold of 1200 feet to 600 feet. These parameters are essential for maintaining safe operational practices in aviation when visibility is compromised.
