Guide to Civil Aircraft Electromagnetic Compatibility (EMC) Webinar

Abstract:

In the webinar, Billy Martin reviews the guidance in SAE ARP60493 for demonstrating that electrical and electronic systems installed on civil aircraft can operate without adversely affecting the operation of other aircraft electrical and electronic systems. This includes guidance for defining appropriate electromagnetic compatibility requirements for the electrical and electronic equipment. It also includes methods for aircraft electromagnetic compatibility analysis and tests.

Simulation technologies have progressed such that full-platform electromagnetic compatibility analysis is now practical and increasingly common on major programs. Tim McDonald from EMA describes how to use EMA3D to predict the coupling of energy between systems. This will include the siting of intentional emitters and their coupling of fields to units and cables. Further, EMA discusses the analysis to predict the electromagnetic coupling between cables. Finally, EMA describes techniques to consider the modeling of unintentional emissions in installed equipment. At the end of the presentation, attendees will understand the basic steps to perform a platform simulation as well as what may be accomplished using simulation.

 

Speakers:

Billy Martin is one of the world’s most renowned experts in EMC, HIRF and Lightning standards, testing, design and certification. Billy has 40 years of experience in the aircraft industry, most of which he has been a DER in EMC, HIRF, Lightning and other electromagnetic effects. He was the chair of the SAE AE-2 lightning committee for the 18+ years, as well as the chair for the FAA Large Transport Aircraft Fuel System Lightning Protection ARC and one of the principle technical members for the FAA Portal Electronic Device ARC, Chair for SC-234 (PED Tolerance Standard) and Task Group leader for the ARP60493 document. In addition, he has been a major contributor to every major standards committee that has dealt with Electromagnetic Effects for the past 24 years, including the committees that have written the EMC standard, PED standards , HIRF and Lightning rules as well as the test procedures, such as RTCA DO-160.

Tim McDonald, PhD is the President and Co-Owner of Electro Magnetic Applications where he has implemented new system-modeling approaches to simulate the interaction of systems and their electronics with electromagnetic environments in a shorter time, with more accuracy, and at a lower cost. He is a consultant to NASA and DoD major primes for specialty engineering of critical systems, development of novel solutions to EMI/EMC problems, and in the execution of major programs that require verification to electromagnetic environmental effects.
