The Changing Electromagnetic Environment Onboard All-Electric Aircraft, an EMC Perspective

All-electric aircraft (AEA) is an emerging subject, due to its environmental contributions and economical appeal, thus, such technology is progressing at a fast pace towards commercial applications. The changing electromagnetic environment (EME) which such aircraft will endure, encompass not only current technologies, but will experience new EMI effects, originating from future mobile communication, power conversion, and increase in air-traffic. As a consequence of an operation relying solely on electric and electrical systems (avionics), together with the implementation of a high-power electric powertrain, AEA will experience increased levels of EMI. Therefore, to regulate the EMI changes onboard AEA, current aerospace standards must be assessed in order to identify possible limitations and bottlenecks. This paper presents an insight into the future EME, its EMC issues, and the intricacies towards the implementation of AEA for regional commercial flights.
