EMC tests (electromagnetic compatibility) are used to ensure that electrical devices, including their partly wireless communication paths, do not interfere with each other and thus fulfil their functions incorrectly or not at all. In aircraft, the sensitive antenna systems, which are used for the instrument landing system, for example, play a major role in ensuring that they are not impaired by the installation of modifications.
Experimental installations must also not interfere with the existing avionics. To this end, measurements are carried out in the Institute's EMC laboratory during development. Identified interference emissions can often be reduced to a safe level with suitable countermeasures. EMC is also of great importance for electric flight, for which the institute carries out measurements on electric motors and investigates faults. Further research topics are being worked on in the field of transfer paths and measurement methods.
