Methodology for analyzing the effects of disruption and its criticality (FMECA) For the feeding circuit in the optical collision avoidance and positioning system of the Cessna aircraft

Abstract

Failure Mode Effects and Criticality Analysis (FMECA) methodology is a preventive tool that contributes to ensuring the reliability and safety of

products and manufacturing processes. This methodology is applied during the design and development stage, during which the seriousness of the design components is assessed with the aim of eliminating them or minimizing their impacts and embarrassment with regard to safety, and appropriate corrective actions are taken and the design is modified so that it is validated at a later stage. This paper provides a detailed explanation of the methodology Failure Mode Effects and Criticality Analysis of the feeding circuit of the optical system installed in the Cessna agricultural plane. This is done by applying it to estimate the severity of the components and calculating their Criticality using XFMEA software based on the American standard MIL-STD-1629A.
