判断正误True or False：自动交输用以修正机翼油箱燃油的不平衡 powered crossflow is used to correct an imbalance between wing tanks.

判断正误True or False：在发动机关车状态下，中央油箱的燃油可以自动传输至两侧机翼油箱。As both engines shut down，the fuel in the center tank canbe automatically transferred into wing tanks。

判断正误True or False：飞机在地面准备起飞时，如果燃油不平衡值超过136kg，会有信息FUEL IMBALANCE显示。As then aircraft on the ground and ready for takeoff，if the imbalance exceeds 136kg，FUEL IMBALANCE caution message appears.

判断正误True or False：当使用人工交输平衡燃油时，当两个机翼油箱油量差减小到一定值时，燃油交输会自动停止。When manual crossflow active，as quantity difference between the wing tanks are within limits，Fuel crossflow will stop automatically.

以磅每小时或公斤每小时为单位的燃油流量（FF）的数字读数显示在哪个位置？Where is the digital readout for fuel flow(FF) in PPH or KPH displayed?

判断正误True or False：EICAS对气源系统和引气泄漏探测系统的信息显示在主页、状态页、环境控制系统（ECS）以及防冰（ANTI-ICE）简图页中。EICAS indications for the pneumatic and leak detection systems are provided on the primary page, status page and the ECS and ANTI-ICE synoptic pages.

判断正误True or False：APU电子控制组件（ECU）控制APU LCV的打开、关闭及调节。The APU ECU controls the opening, closing and modulation of the APU LCV.

判断正误True or False：通过调节隔离活门来控制APU输出的引气流量。The isolation valve（ISOL） is modulated to control the amount of bleed air taken from the APU.

判断正误True or False：引气总管位于发动机吊架和后设备舱内。The bleed air manifold is located in the engine pylons and aft equipment bay.

判断正误True or False：当APU关车、ECU或ACSC信号丢失时，APU负载控制活门关闭。APU shutdown or the loss of the ECU or ACSC signal closes the APU LCV.
