In this paper, the minimum function of civil aircraft power supply emergency is defined based on the model- based system engineering method and the principle of ensuring aircraft flight safety. Through functional architecture-logical architecture-physical architecture modeling, realize the mapping from minimum functions to minimum equipment. The system equipment that needs to work under the emergency electrical power supply of each aircraft system is sorted out from the forward direction, and the electricity requirements of the electrical equipment in different scenarios are analyzed statistically, and then the emergency electrical power requirements of the whole aircraft are obtained as the design input of the electrical power system.
