摘　　要：A类性能是运输类直升机的典型特征,A类性能飞行试验是表明符合性的最佳途径。以CAAC颁布的相关A类性能适航文件为基础,分析A类起飞性能产生的背景,研究相关规章条款的要求和符合性方法,探讨极限高度—速度包线、A类起飞航迹、A类继续起飞和中断起飞以及最终起飞决断点确认等试飞技术,制定无障碍机场A类性能起飞决断点试飞风险管控措施。构建的直升机无障碍机场A类性能起飞决断点试飞方法及试飞风险管控措施,有效地指导完成了AC312E、AC313等直升机的局方审定飞行试验工作,为其获得CAAC型号合格证奠定了基础。CAT-A performance is a typical feature of transport helicopter,meanwhile CAT-A performance flight test is the best way to verify its conformity.Based on the relative CAT-A performance airworthiness documents issued by CAAC,the background of CAT-A take-off performance is analyzed in this paper,the relative clause requirements and compliance method are researched,the flight test techniques concerning H-V envelope curve,CAT-A take-off flight path,CAT-A continued take-off,aborted take-off,and the determination of final take-off decision point are discussed.The CAT-A performance take-off decision point flight test risk management and control measures for clear runway are made.The CAT-A performance take-off decision point flight test method and flight test risk management and control measures specified in this paper has effectively instructed the CAAC certification flight test toward AC312E,AC313,laying a sound foundation for the above mentioned helicopters to acquire CAAC type certificates.
