在飞行中，霾对观察飞机活动或地形特征的影响有：
1 霾中飞行时玻璃窗常变得模糊不清，能见度常小于2 千米； 2 在霾中飞行使眼睛工作负荷过大，地形特征很难看清； 3 霾能产生比离实际跑道距离高的感觉，使得飞行员进近偏低； 4 霾层常与逆温层相连，其下常有风沙天气； 5 迎着太阳飞行时，霾层顶强烈反射太阳光，使飞行员看不清前方的目标。 正确答案是

总管压力读数显示在什么地方？Where are manifold pressure readouts presented?

判断正误True or False：在环控 (ECS)或防冰简图页上没有显示外部地面气源接头和管路。The external ground air connector and duct are not depicted on either the ECS or ANTI-ICE synoptic pages.

进近时，起落架放下，襟翼大于20度，引气负荷：On approach, with the landing gear down or flaps greater than 20, bleed air loading:

哪个区域没有被引气泄漏探测系统监控？Which area is NOT monitored by the bleed air leak detection system?

如果一个单传感环路探测到了引气泄漏引发的高温：If a single sensing loop detects a high temperature associated with a bleed leak:

APU和发动机运转，引气在自动模式且没有结冰条件，地面操作的引气源是什么？What is the bleed source used for ground operation with the APU and engines running, bleeds in AUTO mode and no existing icing condition?

进近时，什么时候引气负荷将自动从发动机转换到APU：On approach, bleed air loading will automatically transfer from the engines to the APU when:

在地面运行，当APU负荷控制活门打开时，隔离活门：when the APU load control valve is open during ground operations, the isolation valve is:

起飞之后，引气负荷会自动转移到发动机，当油门杆从起飞卡位收回且：After takeoff, bleed air loading automatically transfers to the engines when the thrust levers are retarded from the takeoff detent and the:

判断正误True or False：引气管理由2个空调系统控制器自动控制。Bleed air management is automatically controlled by two air conditioning system controllers.
