The smartphone in your pocket, the tablet you use to browse the web, the safety systems in your automobile: they all benefit from fast-evolving computer and electronic component technology. These components are lighter, hold more data, and can perform increasingly complex tasks. This electronic evolution has had an impact in the aviation industry as well. The electronic components used in today's engines can do more than ever before, but the need to replace older components has introduced some added complexity. Until now. The problem is obsolescence. Driven by an ever-demanding consumer market, electrical components - including those used for aircraft engines - are evolving faster than ever. Engine components installed just a few years ago are no longer being made. This means engine manufacturers need to install new models when replacing these older models or when building new engines.

From a past perspective, System Engineering was able to control the product data accuracy with respect to its requirements and towards product certification and delivery avoiding operational disruptions in the development lifecycle. But we usually do it by increasing the complexity of the product data management and administration what makes heavier the product integration. The trends indicate that the product complexity is intensifying and that the increasing load rate of changes will create serious efficiency disruptions if we persevere with today System Engineering approaches. New System Engineering paradigm is then proposed. It conducts to an innovative management of product identification and business integration.

The power plant is the area in an aircraft where they are a lot of power conversion. The power plant is the core of the aircraft from energy point of view. The engines allow to take off but not only, it also provides energy to the aircraft from many different manners. They are electrical, hydraulic, mechanical, …. The power plant is definitively a power generator but also a power consumer. Since now some years, the power electronic technology is spread into the aircraft. One can say that some pedigree has been collected with this technology embedded to the aircraft. For the power plant domain, it is different. This technology is really not usual for use. Our environment is really not friendly and even if the integration of the power converters has been improved over the last years, there is not a lot of space around the engines. These are probably the mains reason of the low deployment of the power electronic in this domain but not only.
