Abstract : Wind turbines installed nearby the means of Navigation (VOR) and Surveillance (primary and
secondary radars) operated by Civil Aviation impact their performance by degrading the precision of
localization and being a source of fake information.
French regulations oblige wind project developers to get the authorization of the Civil Aviation for
any wind farm located within a limited distance fixed by decree according to the equipment
concerned.
In the absence of a simple simulation tool that can be used by a non-specialist, the notices
elaborated by Civil Aviation services are based on an estimation of the risks of disturbance of the air
traffic picture provided to the air traffic controllers. This approach is based on technical and
operational criteria taking into account the average levels of diffracted power, the nature of the
impacted spaces and the density of traffic that evolves there.
