Advanced Diagnostics

Abstract

The maintenance of avionics systems on current Air Force aircraft is plagued by problems in the areas of fault detection and fault isolation. Despite the built-in-test capabilities included in many subsystems and the availability of some diagnostic aids, there remains a costly problem of unnecessary removal of serviceable line-replaceable units (LRUs). This report describes the findings of a study conducted to assess current diagnostics processes and capabilities, define problem areas, and identify developing technologies with the potential to significantly improve the capability of Air Force units to accurately diagnose system failures. The study provided essential background for a new Air Force Research Laboratory program to address the diagnostics problem. This program, Predictive Failures and Advanced Diagnostics (PFAD), developing technology to more effectively isolate system faults and, where possible, accurately predict failure of a specific component before it occurs.
