x Center of gravity is the point at which an airplane would balance if suspended .Its distance from the reference datum is. found by dividing the total moment by the total weight of the airplane.
A.重心是飞机悬浮时保持平衡的点。它与答案：基准的距离是通过总力矩除以飞机的总重量得出的。 B.飞机的重心是使飞机保持平衡的点。它与答案：基准的距离可以通过总弯矩除以飞机总重量找到。 C.重心是如果飞机悬着使飞机保持平衡的点。它到参照基准的距离可以通过总长度除以总重量找到。正确答案A
