By studying on operational principles of governor propeller test stand and governors test program are made up . Repaired governors need test on the test stand and test-fly in mid air .

对调速器、螺旋桨及测试台的工作原理进行研究，编制了调速器测试程序，对修理后的调速器进行测试验证和 装 机 飞行 验证。

It is found that the data precision of atmosphere data sensor is affected during the test-fly of a certain plane . The reason for this is that ( sensor 's ) output signal on the transmission cable brings on a self-excitation caused by distributed capacitance .

在某 型飞机的 试飞过程中，发现大气数据传感器的输出信号在传输线上，有分布电容对其进行干扰而产生自激，影响了传感器的数据精度。
