What does RVR stand for?

RVR stands for "Runway Visual Range." This term is critical in aviation, particularly in the context of instrument approaches and landing. RVR is a measurement that describes the horizontal distance a pilot can see down the runway, which is essential for assessing visibility conditions during takeoff and landing.

The RVR value helps pilots determine whether they can safely land given the prevailing runway conditions, especially in low visibility situations like fog, rain, or snow. It is reported in meters or feet and is a standard part of the weather reports a pilot reviews before proceeding with landing or takeoff operations.

Understanding RVR is key for maintaining safety during approach and landing phases of flight, where visual references are necessary to ensure accurate and safe operations. It emphasizes the importance of having real-time data on visibility directly at the runway, which helps in navigation and decision-making for pilots.
