Runway Visual Range (RVR) is a measurement used in aviation that indicates the distance a pilot can see down the runway. This metric is particularly important for assessing visibility conditions, especially during takeoff and landing operations. RVR is typically measured in meters or feet and is derived from information obtained from runway lighting systems or visibility sensors. RVR readings help pilots and air traffic control determine whether conditions are suitable for landing or takeoff.
