Technology could ease wind turbines’ interference with ATC

Raytheon and National Air Traffic Services next spring hope to complete a test that will certify a project that will allow air traffic radars to distinguish between aircraft and wind turbines. Raytheon officials note that the multiple government agencies involved and the cost of the project could slow its adoption. “There’s a lot of discussion taking place between everybody, but there isn’t anybody who is tagged as lead,” noted Peter Drake, Raytheon’s technical director for Digital Airport Surveillance Radar. Meanwhile, observers note that wind turbines’ interference with the air traffic control system is already stunting the growth of wind power. CNET
