Failure Modes, Effects and Criticality Analysis (FMECA) of Category III Instrument Landing System

摘要

A Failure Modes, Effects and Criticality Analysis (FMECA) is used to optimize system performance by identification (and subsequent elimination) of all potentially hazardous failure modes affecting either personnel safety or operational mission success. The in-depth systematic approach of such an analysis provides the quantitative assurance that the system design has achieved the highest standards of system reliability and integrity. All relevant hidden equipment failure modes are identified within the analysis and, based upon allowable probabilities of occurence, their respective preventive maintenance frequencies are specified.
