Abstract:

A Failure Modes, Effects and Criticality Analysis FMECA is used to optimize system performance by identification of all potentially hazardous failure modes affecting either personal safety or operational mission success. This in-depth systematic approach of such an analysis provides quantitative assurance of the systems reliability and integrity. The previous FMECA performed is updated to determine the impact on localizer and system reliability of the additional equipment required by the substitution of the traveling wave antenna array for the wide aperture parabolic antenna. All relevant hidden equipment failure modes are identified within the analysis and based upon allowable probabilities of occurrence, their respective preventive maintenance frequencies are specified.
