80节以前出现以下什么情况应当中断起飞:1主警告警戒电门灯亮 2系统失效 3声音或震动异常 4轮胎爆破 5加速异常缓慢 6起飞形态警告？ Due to which of the following conditions shall the takeoff be rejected before 80knots? 1 Master warning and caution switchlight illuminates; 2 System fails; 3 Abnormal sound or vibration; 4 Tire burst; 5 Extreme slow accelleration; 6 Takeoff config warning.

下列哪些由3号液压系统提供动力： Which of the following are powered by hydraulic system 3：

判断正误True or False: 2号液压系统控制方向舵、右侧副翼、右反推。 Hydraulic system 2 controls rudder, right aileron and right thrust reverser.

液压系统1和2的主要部件有： The main components of Hydraulic system 1&2 includes:

在双发故障的情况下(液压发动机驱动泵和整体驱动发电机不工作)，ADG自动放出，主飞行控制系统将从（）液压泵上获得液压动力。In the event of a double engine failure (the hydraulic EDP and IDG inoperative), ADG will automatically deploy, the primary flight controls will remain hydraulically powered from ACMP（ ）

左副翼由液压系统( )提供动力。The left aileron is powered by hydraulic system ( ).

右副翼由液压系统()提供动力。The right aileron is powered by hydraulic systems ( ).

判断正误True or False: 液压关断活门的功能是中断从液压油箱到发动机驱动泵（EDPs）的液压油流量。The purpose of the HYD SOVs is to interrupt the flow of fluid from the reservoir to the EDP.

判断正误True or False: 通过HYD SOV电门/灯关闭液压关断活门可以控制液压油超温，而不需要关闭发动机。The HYD SOV switch/lights provide an alternate method of closing the shutoff valves eliminating the requirement to shut down an engine to control fluid overtemperature.

判断正误True or False: 在三套液压系统中，3号液压系统提供最大的液压需求。System no. 3 services the largest demands of the three systems.

判断正误True or False: 液压系统3冷却不需要使用热交换器。Hydraulic system no. 3 cooling does not use a heat exchanger.
