简单用户微编码器件适航要求研究

Research on certification requirement of simple custom micro-coded component

用户微编码器件的便捷性与高效性,使其在机载设备研制中被广泛应用。由于具有高度集成性和复杂性,难以通过传统方法对开发过程中产生的设计错误进行管理和评估,其使用会对飞机的安全性造成影响,因此通常采用研制保证方法表明用户微编码器件的适航符合性。但在实际项目中,用户微编码器件实现的功能可能较为简单,采用充分的确定性测试和分析相结合的方法足以表明其功能确定性,确保其在机载设备中的使用安全性。通过对现有适航咨询通告、工业标准及实践指南等资料的分析和研究,旨在梳理出简单用户微编码器件通过充分的确定性测试和分析相结合的方法表明适航符合性需满足的相关要求和关键要素,为机载设备制造商完成简单用户微编码器件的适航验证提供支持和帮助。

Custom micro-coded components are widely used in the development of airborne equipment because of its convenience and high efficiency.Due to its high integration and complexity,it is difficult to manage and evaluate the design errors in the development process by traditional methods,and the components use will affect the safety of aircraft.Therefore,the design assurance method is usually adopted to demonstrate the airworthiness compliance of the custom micro-coded component to certification requirements.However,in practical projects,the function implemented by the custom micro-coded component may be relatively simple.The component functionality visibility can be shown by comprehensive combination of deterministic testing and analysis,and safety of component use in airborne equipment can be assured.Based on analysis and research of current advisory circular,industry standards and practical guidelines,the goal is to sort out the relevant requirements of the custom micro-coded component and key elements should be fulfilled to show compliance by comprehensive combination of deterministic testing and analysis to support and help airborne equipment manufacturers apply for airworthiness certification of simple custom micro-coded component.
