If one of these was elevator trim though you would have to visually look to see it's neutral every time before takeoff rather than being able to center it by feel.

如果这些中的一个虽则是电梯修剪您视觉上会必须看看它在起飞之前每次是中立的而不是能由感觉集中它。

For any C. G. position, an increase in trim speed from any initial value to a larger one requires a downward deflection of the elevator.

对于任意一个重心位置，平衡速度由它的初始值变化到较大的值时要求升降舵向下偏转。
