An effective runway visual range (RVR) system provides pilots and air traffic controllers with crucial visibility data, essential for informed decision-making. Weather is a significant cause of delays in the National Airspace System, responsible for nearly 75% of delays and over 20% of general aviation accidents. Low visibility remains a persistent challenge.
Weather events like fog, heavy rain, snow, and sandstorms can drastically reduce visibility, affecting airport operations and safety. An efficient RVR system offers real-time data to address these challenges.
Visibility is defined differently depending on context. The International Civil Aviation Organization (ICAO) defines it for aeronautical purposes, while the World Meteorological Organization measures atmospheric visibility as meteorological optical range (MOR). RVR measures the distance visible along a runway using lights and markings. It can be up to five times greater than MOR at night.
