IMA System Overall Fault Management Method Research Based on ASAAC Architecture

Abstract

This paper describes the architecture of the integrated modular avionics (IMA) system; summarizes the various fault management functions; and proposes an extended layered IMA system overall fault management architecture combined with fault prognosis and fault handling functions based on the European allied standard avionics architecture council (ASAAC) standards. The logic process for each level of overall fault management and the implementation method of the overall fault management of IMA system are given.
