这时候要求我们稳定的控制操纵，并且在速度减小到失速速度之前使飞机低头，在满油门的情况下加速。

We ought to hold the column and make the aircraft nose down to accelerate with full poser before reach to the stall speed.

One is inertial mass, which is how much you hate your velocity to change, how hard you resist acceleration.

一个是惯性质量,它反映了物体速度改变的难易程度,即保持加速度的难易程度
