When the Windmill and hostile aircraft in the sky

That a plane crashed into a windmill, the likelihood is very small. But the windmills can be fatal to flight activity.

A plane crashed into a windmill ? Such a scenario is rarely the headache of airport traffic controllers . There are other things which they think are threatening , " the problem lies in the navigation system , " said Axel Raab , spokesman for the German Aviation Security .
Because during flight in the air , the plane will be passed by means of which emit radio waves to aid navigation . The plane then will catch the signal to measure its position . However, windmills or other buildings can reflect signals will then be captured by the aircraft as an alias Noise nuisance - and deviate from the path of flight .
The biggest problem is the signal interference caused by the wind farm . Stefan Hawlitschka of the Fraunhofer Institute for Communication and Information Dissemination ( FKIE ) complained that such interference signal can not be corrected by the aircraft computer system . Because windmills spinning wheel causes the emission signal becomes discontinuous irregularly .
" If the site is near the airport , in a worst case scenario of two planes could collide . Such a thing should not happen , " said Axel Raab in an interview with DW .
Therefore Aviation Safety Agency ( BAF ) 2009 imposing 64 security zones throughout Germany that prohibit the construction of wind power plants .
Regulation Bitter Wind Parks for business
Create windmill industry regulations could mean a loss . Because the area around the major airports such as Frankfurt radio transmitter density is so great , that energy producers are no longer able to find a place to build a windmill . According to the windmill lobby kelompokk claims , in Germany alone was 208 wind energy projects that failed due to the regulation of aviation security zone . Lost capacity of four gigawatts thinks - equal to the production capacity of three Tenagah Nuclear Power Plant
Therefore windmill manufacturers and power companies since the past few months complained of a general rejection of the wind park in aviation security zones . They demanded that the regulation is loosened .
Satellite Navigation Not Adequate
Recently, the government of France and the UK does provide an exception for the project was the construction of wind parks in the aviation security zone . Nevertheless insisted Flight Safety Monitoring Board refused .
Director Nikolaus Herrmann BAF claimed , that had a lot of wind parks are built in Germany even before the flight safety zone is enforced. " Jug is full , " he said . In Germany by Hermann there are many convenient locations to serve the wind park . Security , he said , has the highest priority .
However Hermann admits , community-owned wind farm there is no other alternative places , like those of large companies . The greatest hope for the aviation industry is a satellite navigation technology . However, these technologies are still less accurate complained , so the airport is not going to part of a radio transmitter .
