Wind energy plants over 100m tall present a risk to aviation traffic – especially during night time, fog and stormy weather. The Air Traffic Act dictates wind plants over 100m tall must include an aviation warning system. Traditionally, warning systems consist of a red flashing light placed at the top of the plant. However, this can disturb local residents and wildlife.  

The new „passive radar system“ provides a new solution – warning aviation traffic whilst not disturbing local residents. Only when an aircraft approaches the wind turbine is the warning light activated. The system uses existing radio signals and does not transmit radar radiation. This creates an affordable safety system, that considerate to both local residents and wildlife. The slogan is: ‘The night shall remain dark’.
