China is running a large number of foreign advanced civil aircraft.These aircraft are all equipped with flight data quick access recorders to collect flight data for flight quality monitoring.Besides being able to play a role in airline operation,the daily flight data of civil aircraft can also analyze the design experience and operation characteristics of advanced models through technical analysis.The relevant technical achievements have certain reference significance to the development of domestic civil aircraft manufacturing industry.Actual case analysis shows,the analysis based on QAR data can effectively respond to the design logic embodied in the altitude maintenance control law of the automatic flight phase,which can benefit the design and optimization of the domestic civilian aircraft.%中国国内运行着大量国外先进民用飞机.这些飞机全部装有飞行数据快速存取记录器,以采集飞行数据开展飞行品质监控工作;民机日常飞行数据除了能够在航空公司运行中发挥作用,还能够通过技术手段分析得出先进型号的设计经验与运行特点,相关技术成果对国产民机制造业的发展也具有一定的借鉴意义;在分析国内外相关研究基础上,以两款国外民机巡航段飞行数据的分析为例,解析了两型飞机的高度保持控制律设计逻辑,实际案例分析表明,基于QAR数据的分析能够有效地反应在自动飞行阶段高度保持控制律中体现的设计逻辑,从而有助于对国产民机的设计和优化.
