ABSTRACT

The advent of digital electronic technology in electrical/electronic systems has enabled unprecedented expansion of aircraft system functionality and evolution of aircraft function automation. As a result, systems incorporating such technology are used more and more to implement aircraft functions, including Level A systems that affect the safe operation of the aircraft; however, such capability does not come free. The EME (electromagnetic environment) is a form of energy, which is the same type of energy (electrical) that is used by electrical/electronic equipment to process and transfer information. As such, this environment represents a fundamental threat to the proper operation of systems that depend on such equipment. It is a common mode threat that can defeat fault-tolerant strategies reliant upon redundant electrical/electronic systems.
