EMC
EADS Military Air Systems operates one of the world's most up-to-date electromagnetic compatibility (EMC) test facilities at its Manching site. It can be used to test the electromagnetic compatibility of an entire airborne system.

EMC comprises the analysis of possible mutual interference and impairments of function among individual systems, but also the interaction of the aircraft as an entire system with external electromagnetic fields, e.g. mobile phones, radio, radar, television transmitters, storms, etc. The EMC measurements cover the various individual electronic elements such as amplifiers, subsystems such as on-board radars and, of course, the aircraft as a complete system too. EMC tests establish the field strengths of the emissions and can be subdivided into three major areas: firstly, to prove that a system's own radar or jamming emissions do not affect the operation of the overall system in the various modes; secondly, to measure the resistance of the overall system to irradiation from external sources; finally, to examine the ways in which all the subsystems may affect each other in all their possible switching states. The goal here is to simultaneously meet all three requirements with as little negative interaction as possible.
