SupAirVision and the drones used for wind turbine inspections are registered with the DGAC (Direction Générale de l'Aviation Civile). On wind farms, we are concerned by scenario S1, free zones, flight < 200 m of the pilot and < 150 m height. A prefectural authorization - scenario S3, urban areas - is therefore not required to carry out blade inspection. Any other authorization is exceptional due to the configuration and location of the wind farms (total height less than 150 m, excluding air corridors and military areas).
