It can roll about a line from nose to tail — the longitudinal axis; and it can yaw, left or right, about the vertical axis.

他可以绕着从机头到机尾的纵轴来翻滚；并且可以绕着竖轴向左或向右偏航。

Yaw axis - Vertical axis, passes through the airplane from top to bottom - left and right control is by rudder.

偏航轴—又称垂直轴。由机身上方通向下方。飞机绕此轴转动即造成机首之左右运动，此一运动由方向舵控制。

I push on the rudder pedal and begin a yaw rate turn to the left.

我蹬方向舵踏板使飞机沿Y轴向左进入滚转。
