Design of logic processes for prognostics and health management in an avionics system

Abstract

Avionics systems perform critical functions in modern aircrafts. Intelligent technologies of prognostics and health management (PHM) are necessary in avionics systems. This paper discussed the architecture of an avionics PHM system, and showed and explained the flowcharts of the logic processes in different levels of the avionics PHM system in detail. A database and a model library needed in the PHM system were designed.
