Every request for opinion regarding wind turbines is analysed for its potential impact on the technical installations (radio navigation, radar and communication systems) managed by skeyes. In addition, it is assessed whether the installation at the requested location would disrupt operations – with particular attention to visual reporting points and holding locations – and flight procedures (obstacle-free surfaces around controlled airports) for the airports under skeyes’ control.
The criteria applied by skeyes are based on ICAO regulations, studies commissioned by skeyes, international studies in which skeyes has participated (including Eurocontrol), international guidelines, information exchanged in various forums in which skeyes actively participates (ICAO, Eurocontrol, etc.), the experience of other air navigation service providers (ANSPs) and skeyes’ own experience.
The Wind Turbine Consultation Map shows, for each zone, what type of study is required and where wind turbines cannot be permitted for safety reasons. The reference criteria are shown on the map using different colours (outlined, hatched and shaded zones). Installation criteria and procedural criteria may overlap. In any case, skeyes will analyse all criteria individually.
Every technical installation at skeyes is protected by a no-go zone. To ensure aviation safety, wind turbines cannot be permitted in these zones.
This map has been drawn up for wind turbines with a maximum tip height of 300 metres. For larger turbines, as well as for wind farms comprising 10 or more turbines (including those already built and/or granted planning permission) or in the case of a cluster with a potential cumulative effect depending on the location in relation to the installations and procedures, an ad hoc assessment will always be required.
During the construction phase, once all the necessary permits have been obtained, the client must notify skeyes at least 30 days before work commences, so that the new obstacle can be published in the AIP (Aeronautical Information Publication) in good time.
