Why do wind turbines flash?
The night-time flashing of wind turbines is more than just a visual phenomenon - it is an essential safety mechanism for air traffic.
Invisible by day, widely visible at night: The characteristic blinking of wind turbines shapes the nocturnal landscape in many places. Behind this spectacular sight lies sophisticated aviation safety technology. Yet many wonder: Why do wind turbines actually need to blink?
With heights exceeding 200 meters, modern wind turbines intersect flight paths of airplanes and helicopters. The nocturnal blinking of wind turbines - the rhythmic obstacle lighting - serves three key functions:
Above 100 meters, the "General Administrative Regulation for the Marking of Aviation Obstacles" mandates this marking. We'll spare you the complex legal jargon and summarize the key facts about wind turbine blinking.
The regulation defines:
While aviation safety remains the top priority, the constant nocturnal blinking often disrupts residents' sleep. This doesn't make wind turbines any more popular in local communities.
The Aircraft Detection Lightguard System (ADLS) resolves this conflict. It activates the beacons only when aircraft approach.
Light:Guard has perfected this technology and supports wind farm operators with ADLS integration:
Benefits of Smart Wind Turbine Marking:
The Aircraft Detection Lightguard System revolutionizes wind turbine lighting - a milestone for wind energy acceptance.
