Approach to Implementation of Power Management with Load Prioritizations in Modern Civil Aircraft

Any use of energy in industrial productive activities is combined with various environment impacts. Withintransportation, this fact was not only found among land transport, railways and maritime transport, but also in the air transport industry. An effective climate protection requires strategies and measures for reducing all greenhouses gas emissions, in particular carbon dioxide, and must take into account the economic, ecologic and social aspects. It seemsimperativenow to develop and manufacture environmentally friendly products and systems, to reduce consumption and use less resource, and to save energy and power. Today’sproducts could better serve these requirements taking into account the integration of a power management system into the electrical power system.This paper gives an overview of an approach ofpower management with load prioritization in modernaircraft. Load dimensioning and load management strategies on current civil aircraft will be presented and used as a basis for the proposed approach. Keywords—Load management, power management, electrical load analysis, flight mission, power load profile.
