The introduction of wind powered turbines within the United Kingdom, as part of an alternative energy policy, can create certain problems for aviation. In addition to their potential for presenting a physical obstacle to air navigation, wind turbines can affect signals radiated from, and received by, aeronautical systems. The rotating blades create electromagnetic disturbance, which can degrade the performance of these systems and cause incorrect information to be received. The amount of interference depends on the number and size of wind turbines, construction materials and location, and even the shape of their blades.
