If a gyro is used to measure the rate of rotation around the aircraft roll axis, it will measure a non-zero value as long as the aircraft is rolling, but measure zero if the roll stops.
使用陀螺仪测量飞机机体轴向的旋转角速率时，如果飞机在旋转，测得的值为非零值，飞机不旋转时，测量的值为零。
As if there is no way to get congruity between flatness and surface roughness, for the control of the latter, larger rolling force during the final pass is expected, while the former stands against.
