Abstract

Avionics are fundamental to the flight management and engine control of today's airplanes. With increasing functional complexity of onboard autonomous avionic systems, there is an increasing demand for system-level health assessment, fault diagnostics, and prognostics, especially to meet critical safety and mission requirements. This article presents the motivation for increased health management, diagnostics, and prognostics for avionics, and then provides a diagnostics and prognostics approach to assess avionics.
