Every request for opinion on wind turbines is analysed with regard to its potential impact on the technical installations (Systems for radio navigation, radar and communication) that skeyes manages. It is also examined whether the establishment at the requested location does not hamper operations, more specifically the visual reporting point and the holding locations and flight procedures (Obstacle free zones around controlled airports) for the airports that skeyes manages.
The criteria that skeyes uses are based on ICAO regulation, studies commissioned by skeyes, international studies in which skeyes participated (Eurocontrol among others), international guidelines, information exchanged in various fora in which skeyes actively participates (ICAO, Eurocontrol, etc.), on experience of other ANSPs and on skeyes’s own experience.
Those criteria have been translated in a simplified manner to the Wind Turbine Consultation Map. On that map all criteria are visually represented by means of zones.
Those zones are:
This map was drawn up for wind turbines with a maximum tip height of 200m. For larger turbines and wind farms as from 20 turbines (including turbines that have already been built and/or licensed) or as from 10 turbines depending on their geographical location, an ad hoc assessment will always be necessary.
At least 30 days before the start of the wind turbine works, the prime contractor has to contact skeyes so as to allow the new obstacle to be published in the AIP (Aeronautical Information Publication).
