基于RTCA/DO-254以及中美适航当局硬件批准指南,对先前开发电子硬件的符合性验证技术进行了深入研究,识别出7种类型的先前开发电子硬件。通过对不同类型的先前开发电子硬件的适航审查要求进行研究,归纳出7种类型的先前开发电子硬件,并针对不同的类型研究制定了适航符合性验证方法和策略,用以指导民用飞机先前开发电子硬件的适航符合性验证工作的开展。
Based on the RTCA / DO-254 and the hardware approval guidelines from the Airworthiness Authorities in both China and the United States, an in-depth study of the compliance verification techniques for previously developed electronic hardware identified seven types of previously developed electronic hardware. Based on the research of airworthiness examination requirements for different types of previously developed electronic hardware, seven types of previously developed electronic hardware are summarized, and airworthiness compliance verification methods and strategies are developed for different types of research to guide civil aircraft Development of airworthiness compliance verification of previously developed electronic hardware.
