摘　　要：航空器噪声审定机构要求航迹测量系统独立,且不限定技术方法。申请人需向审定机构递交设备及测量方案,用于评估,并明确测量准确度相关设备指标。基于局方目前已核准的飞行航迹测试方法,本文详细分析成像比例法与差分全球定位系统法(DGPS)在民用航空器噪声适航审定航迹测试中的应用,针对以上2种方法,详细阐述了噪声审定过程中的主要验证内容、验证工具、验证方法及审查判据,为民机噪声适航审定提供科学方法。The authority requires that the track measurement system be independent and does not limit the technical method.The applicant needs to submit the equipment and measurement plan to the airworthiness agency for evaluation and specify the equipment indicators related to the measurement accuracy.Based on the flight path testing methods currently approved by the authorities,this article analyzes in detail the application of imaging ratio method and differential global positioning system(DCPS)method in the noise airworthiness certification flight path testing of civil aircraft.Regarding the above two methods,the main verification content,verification tools,verification methods and review criteria in the noise certification process are elaborated in detail,providing scientific methods for the noise airworthiness certification of civil aircraft.
