摘　　要：纵向静稳定性试飞属于飞行试验科目中的经典科目,依据CCAR25部要求,传统民用运输机执行此科目时主要考察飞机改变速度所需的杆力方向、杆力-速度平衡曲线以及操纵结束后飞机速度的恢复能力。但对于具有纵向中立静稳定性设计特点的全电传飞机,传统的适航条款和试飞方法都已不再适用。在咨询通告AC25-7C和某型飞机专用条件的基础上,给出了使用操纵品质等级评定方法(HQRM)来开展纵向静稳定性试飞的基本方法和判据要求。Longitudinal static stability flight test is a classical flight test subject. According to CCAR 25, the longitudinal static stability flight test is to verify the control force vector,force versus airspeed curve and airspeed recovery ability after control release for the conventional aircraft while for fly-by-wire aircraft with longitudinal neutral static stability, conventional airworthiness requirements and flight test method are not applicable. Based on AC25- 7C and special conditions of certain aircraft, the handling quality rating method （HQRM） is presented to evaluate longitudinal static stability in this paper.
