（案例分析）某航CRJ900在进近过程中，高度30英尺，突然跑道上闯入另外一架飞机，机组决定复飞，副驾驶操纵飞机，机长立即收到襟翼8度，造成飞机突然下沉接地，副驾驶此刻加油门至复飞推力，开始增加姿态复飞，造成机尾擦地。请分析以上机组执行任务复飞动作是否正确以及可能造成擦机尾的原因。(Case analysis) During the approach of one Airline＇s CRJ900 , at 30ft，there＇s suddenly another aircraft incursion the runway, the crew decided to go-around, the copilot took control of the aircraft, and the captain immediately retracted flaps to 8, causing the aircraft suddenly sinking to touch the ground. The copilot advanced the thrust to T0/GA at this moment and started to increase the go-around attitude, causing the tail strike.
Please analyze whether the flight crews perform the go-around maneuver correctly and the reasons that might cause the tail strike.

对流层顶的高度随纬度的变化是

A. 随纬度的增大而降低

B. 随纬度的增大而增高

C. 在中纬度地区最高

判断正误：正常起飞推力的额定功率是13360 lb (59.43 kN) 。True or False:Normal take-off thrust – 13360 lb (59.43 kN)

A. 风向不变

B. 由右侧风变为左侧风

C. 由左侧风变为右侧风

最低扇区高度MSA对扇区内所有障碍物提供的最小超障余度是( )。

A. 2000英尺

新版航空安全差错标准中，仪表进近偏离水平或垂直轨迹，飞机触发TOO LOW TERRAIN音响警告，仪表进近偏离水平或垂直轨迹，飞机触发TERRAIN引起PULL UP音响警告，为航空安全严重差错。（ ）

液压系统1和2液压油使用位于后设备舱的单个空气/液压热交换器冷却。 以下适用于所描述的系统的是：Hydraulic systems 1and 2 hydraulic fluids are cooled using a single air/hydraulic fluid heat exchanger which is located in the aft equipment bay. The following applies to the described system.

A. 尽管系统1和2共享同一套热交换器，但两套系统之间没有液压油混合。Although systems 1 and 2 share the heat exchanger there is no mixing of hydraulic fluid of the two systems.

B. 由于只有一个热交换器，两个系统都必须被增压以防止两个系统之间的液压油混合。Since there is only one heat exchanger both systems must be pressurized to prevent mixing of hydraulic fluid between the two systems.

C. 在地面上必须避免使用液压系统1和2，因为液压滑油冷却不充分，而与外部空气温度无关。On ground use of hydraulic system 1 and 2 must be avoided because of insufficient cooling of hydraulic oil, independent of the outside air temperature.

D. 在启动期间的极低温度（10℃和更低）下，热交换器冷却空气旁通热交换器。At very low temperatures (10C and lower) during start-up the heat exchanger cooling air is by- passed around the heat exchanger.

判断正误true or false：当选择速度方式时，速度基准（显示在PFD上）将被设定为当前空速。When speed mode is selected, the speed reference (primary flight display) is set to the current airspeed
