Electromagnetic compatibility studies (ILS and ASR) concerning new fire station at Frankfurt/Main airport completed

March 2017 | Safety Assessment

Within the scope of the construction planning of a new fire station in the south of Frankfurt/Main airport an electromagnetic compatibility study for relevant CNS facilities has to be carried out according to § 18a LuftVG (german air traffic act) and requirements of the competent authority as well as Federal Supervisory Authority for Air Navigation Services (BAF). In cooperation with our partner FCS Flight Calibration Services GmbH, being specialized in high frequency technology, and on behalf of Fraport AG potential interferences between the fire station and the operation of radar and navigation facilities were analyzed. Especially the runways’ localizer and glide slope antennas (ILS), the airport surveillance radar (ASR) and in particular the secondary surveillance radar (SSR) can be affected by disruptive interferences. The assessment of radar facilities is based on state-of-the-art solver software for near and far field simulations permitting the determination of electromagnetic stray fields by using a hybrid method consisting of the Method of Moments (Mom) and Physical Optics (PO). By this technical testing procedure we can offer the currently most modern and most reliable methodology. In the course of the stray field analyzes risk mitigation measures concerning façade construction and material selection were examined. Furthermore, the assessment’s approach was co-ordinated with Deutsche Flugsicherung GmbH (DFS) as operator of the CNS facilities in the project’s early stage. Thus, an unique accuracy concerning the implementation of radar facility parameters is achieved and ensured.
