AI Technical Summary
Technical Problem
In the prior art, unnecessary disconnection of the yaw damper may lead to a decrease in aircraft handling stability and make the aircraft more susceptible to disturbance signals, increasing the workload of the crew.
Method used
By introducing rudder status signals for judgment, a disconnection pre-positioning signal is generated. In response to abnormal operation of the rudder or main flight control system, the yaw damper is disconnected after dual judgment to ensure that it is disconnected only when necessary and to prevent accidental disconnection.
Benefits of technology
It improves aircraft handling stability, reduces unnecessary oscillation failures caused by accidental disconnection, and lowers the workload of the crew.

Abstract
本发明公开了一种用于控制偏航阻尼器断开的方法和系统。在本发明的一个实施例中，在方向舵、偏航阻尼器数据传输路径、和 / 或主飞行控制系统非正常工作时生成断开预位信号，并且响应于断开预位信号，若确定方向舵控制链路或方向舵的偏航功能中的至少一者非正常，则断开偏航阻尼器。
