摘　　要：梳理和分析电传飞控系统共模相关适航要求,创新建立“电传飞控系统共模认知-控制审定流程模型”并提出针对共模问题的审查原则和考虑,有助于全面分析、识别并确定可能的共模失效、提出独立性设计要求,权衡设计解决方案等。应用该模型和审查考虑对某机型电传飞控系统有关复杂电子硬件差错共模的审查案例开展分析,识别确认共模因素和共模失效并分析各设计方案的可行性。研究成果对电传飞控系统及其它复杂系统共模的审查和设计具有指导和借鉴意义。This paper combs and analyzes the airworthiness requirements related to the common mode issues of FBW flight control systems,innovatively establishes the“common mode cognitive-control certification process model for FBW flight control system”and proposes the review principles and certification considerations for the common mode issues,which helps to fully analyze,identify and determine possible common mode failures,propose independent design requirements and trade-off design solutions.By applying the model and certification consideration,the certification case of a complex electronic hardware error common-mode of an FBW flight control system was analyzed,the common mode factors and common mode failures were identified and confirmed,and the feasibility of each design solution was analyzed.The research results have guiding and reference significance for the certification and design of common mode issues of FBW flight control system and other complex systems.
