Airspace Obstruction and Electromagnetic Interfeerence Considerations for Wind Power Projects

Airspace Obstruction and Electromagnetic Interfeerence Considerations for Wind Power Projects

The purpose of this document is to provide a general set of airspace analysis guidelines for wind turbine projects. The FAA criteria which establish the basis for these guidelines are highly complex, especially as they relate to operational impacts on air traffic. There are many instances where FAA operational criteria, both VFR and IFR, are modified on a case by case basis. With that in mind, the Filing requirements and Imaginary Surface considerations are consistent in almost all FAA studies, and should enable the user of these guidelines to understand and calculate the heights associated with these criteria. However, only an experienced airspace analyst should attempt to apply the Operational Impact criteria delineated herein.

The EMI considerations are important in the siting of because pf potential interference to air defense radar and public safety systems. However, there are potential effects on other forms of RF transmission, as well, and these will all be discussed in the EMI section of this document.
