Security Analysis and Preventive Measures of EWIS

Abstract

In the field of airborne electrical equipment safety, the major concern has been focused on the reliability of the equipment, and the long-term neglect of the connection of each of the airborne electrical equipment cable failure. In order to reduce the probability of wire fault effectively, separate it from the airborne electrical equipment system for research. Firstly, starting from the basic problem of the security of EWIS (Electrical Wiring Interconnection System), the steps of the quantitative analysis of the EWIS fault are given. Secondly, based on the analysis of the failure mechanism of the aviation wire, the advantages and disadvantages of different detection techniques are compared. Finally, the scheme of improving EWIS fault detection ability for the new and old aircraft with different maintenance modes is presented.
