2790.The yaw damper works by sensing any yaw motion and then applying corrective inputs to the aircraft's rudder to reduce or eliminate any unwanted yawing.It is particularly useful in minimizing the effects of turbulence or other external disturbances that can cause yawing and make the aircraft harder to control.The yaw damper is an important safety feature that helps to improve the overall stability and control of the aircraft,especially during critical phases of flight such as takeoff and landing.

A. 偏航阻尼器通过感受偏航动作然后将正确的信号输给方向舵来减轻和消除不希望出现的偏航。它在减少尾流和其他外部干扰的影响中很有用,气流和外部干扰使飞机难以操控。偏航阻尼器也是一个改进飞机稳定性和操作性的重要安全特征尤其是在起飞和着陆等关键阶段。

B. 偏航减震器通过感受偏航动作然后将正确的信号输给方向舵来减轻和消除不希望出现的偏航。它在减少气流和其他外部干扰的影响中很有用,气流和外部干扰使飞机难以操控。偏航减震器也是一个改进飞机稳定性和操作性的重要安全装置尤其是在起飞和着陆等关键阶段。

C. 偏航阻尼器通过感受偏航动作然后将修正的信号输给方向舵来减轻和消除不希望出现的偏航。它在减少湍流和其他外部干扰的影响中很有用,气流和外部干扰使飞机难以操控。偏航阻尼器也是一个改进飞机稳定性和操作性的重要安全装置尤其是在起飞和着陆等关键阶段。
