Interference with radar

A major source of objections to upland wind farms has come from the Ministry of Defence.

A major source of objections to upland wind farms has come from the Ministry of Defence because of concerns about wind turbines affecting navigational equipment on aircraft.

The MOD, the Civil Aviation Authority, and the National Air Traffic Services  must be consulted. Urban wind power sites that are close to airfields may be affected.

Large turbine manufacturers are researching the possibility of making rotors using ‘stealth’ technology, making rotors that do not get picked up by radar.
