On the basis of introducing the request and theory of transport category airplanes certification of dynamic stability. A method using modified transient peak ratio caculating dynamic stability of airplane is put forward. Calulating some airplane's flight testing data,the results show the method is easy to use with hign consistency and reliability, which can be used for the certification of any aircraft with small damping ratio.%简要介绍了CCAR25部对于民用飞机动态特性的合格审定要求和原理.提出了一种改善的采用峰峰比值计算飞机动态特性的方法.结合某型飞机飞行试验数据,证明了该方法简单易用,结果准确,可靠性高,可为型号试飞数据处理使用,也可作为一种基本的精确计算方法来检验其它方法.
