"The OCAS system uses radar technology to detect approaching aircraft and activate warning systems. Strobe lights on the turbines will be activated as a visual warning and an audio warning will be transmitted to the pilot's radio if the aircraft doesn't immediately change course.
"The OCAS technology has been tested and approved by aviation authorities in Norway, Sweden, Canada and the United States…It has been installed at more than 60 sites in Europe and North America."
