In the quest for sustainability, wind turbines play an important role to take advantage of one of the most available sources of renewable energy. Airports are equipped with several electromagnetic devices allowing airplanes to precisely know the distance and approaching angle with respect to a radiating antenna placed at the airport facilities. The presence of wind turbines in the vicinity of an airport may alter the behavior of these systems, which would imply a wrong measurement value on the airplane. Nonetheless, numerical electromagnetic methods can provide, accurately, the impact of such environment during the design phase of the nearby wind farm. In this paper, we analyze the behavior of a couple of well-known methods for this sort of study: The Method of Moments (MoM) and the Physical Optics (PO). Due to the electrical size of the turbines at the usual working frequencies of these aeronautic systems, the number of unknowns of the corresponding linear system becomes huge. Therefore, an accelerated technique, such as the Multilevel Adaptive Cross Approximation (MLACA) or the MultiScale Compressed Block Decomposition (MSCBD), will be necessary when using the MoM.
