摘　　要：目前国内在机载电子硬件的电路板级适航审定中主要依据《机载电子硬件设计保证指南》(DO-254),但该文件对电子硬件的设计保证过程及目标在工业实践中存在一定的模糊性。基于此,通过对比分析关于DO-254的国外咨询通告AC 20-152A和备忘录CM-SWCEH-001中对电路板卡级的相关目标要求,结合国外适航当局审定理念和目前国内工业水平现状,提出以咨询通告AC 20-152A作为DO-254的支持材料应用于国内机载电子硬件电路板级审定实践的思路和方法。同时,对咨询通告AC 20-152A中电路板级相关要求开展可行性分析,基于条款意图对其进行优化以适应国内审定现状,并通过实际项目审定案例论证该思路和方法的适用性及优越性。结果表明:该思路和方法可为国内机载电子硬件的电路板卡级适航符合性提供参考和借鉴。This article is to address the ambiguity in the current domestic certification practice based on the DO-254 Airborne Electronic Hardware Development Assurance Guidelines regarding the circuit board level certification strategy and objectives for circuit boards.By comparing and analyzing the relevant objectives for circuit board level in Advisory Circular AC 20-152A and Memorandum CM-SWCEH-001 regarding DO-254,and combining the certification concept of foreign airworthiness authorities and the current domestic industrial circumstance,this paper proposes the idea and method of using Advisory Circular AC 20-152A as a supporting material for DO-254 to be applied in the domestic airborne electronic hardware circuit board level certification practice.Meanwhile a feasibility analysis is conducted on the circuit board level requirements in Advisory Circular AC 20-152A,and based on the intent of the clause,it is optimized to adapt to the current domestic approval status.The applicability and superiori-ty of this approach and method are demonstrated through actual project approval cases.Results show that the idea and method proposed in this paper can provide reference and inspiration for the circuit board level airworthiness compliance of domestic airborne electronic hardware.
