What does RVR stand for?

RVR stands for Runway Visual Range, which is a meteorological term used to describe the distance a pilot can see down the runway. It is an important measurement in aviation, especially during takeoff and landing, as it directly affects a pilot's ability to navigate safely in low visibility conditions, such as fog, rain, or snow. RVR is typically determined by sensors positioned along the runway that measure visibility and can relay this information to pilots and air traffic control. This measurement is critical for ensuring safety during operations at airports and is closely monitored in relation to weather conditions. Understanding RVR helps pilots make informed decisions based on current visibility and runway conditions.
