Today's performance needs for commercial and military avionics systems require increasingly sophisticated electronic equipment and greater use of composite structures. As operational requirements become more critical, the level of electromagnetic interference (EMI) protection for electrical equipment is increasing. Harnessing and termination techniques must change to keep pace with state-of- the-art technologies. By effectively attenuating these undesirable energies on susceptible flight control and monitor wiring, the threat of disturbing electronic systems can be diminished. Some solutions to minimize the effects of EMI on systems through the use of proper terminations and radio frequency absorptive wire are discussed here.
