执行标准目视进近，飞机（襟翼45放出)机动飞行中，为防止机动失速，四转弯速度不得小于（）速度？
To implement a standard visual approach, in order to prevent maneuvering stall, the speed for the fourth turn should not be less than ( ) during maneuvering of the aircraft (flaps 45 deployed)?

判断正误：ECS简图页用于监控APU 负载控制活门(LCV)。True or False: The ECS synoptic page can be used to monitor the APU LCV.

关于APU的什么信息会在EICAS状态页上显示？What kind of APU Indications can be found in the EICAS Status Page?

判断正误：在飞行状态下，发生某些故障时，APU 也不能自动停车。APU 故障警戒信息将会显示，但是 APU 仍将继续工作，直到飞机落地后 30秒，然后 APU 的控制逻辑转为地面模式，并使得 APU 发生保护性停车。True or False: In flight, during certain faults, the APU will not automatically shut down. The APU FAULT caution message will be displayed but the APU will continue to operate until 30 seconds after landing, then the APU control logic reverts to the ground mode and APU protective shutdown occurs.

当按下 APU START/STOP(起动/停车)开关/灯时:When the APU START/STOP switch/light is pressed:(1)      绿色的 AVAIL 开关/灯熄灭(APU GEN 关闭)Green AVAIL switch/light extinguishes (APU GEN tripped OFF).(2)      APU 燃油关断电磁活门关闭APU fuel shutoff solenoid closes.(3)      APU 转速和排气温度下降APU RPM and EGT decrease.(4)      当 APU 转速降到低于 25%时，进气门关闭APU intake door closes when rpm decreases below 25% rpm.(5)      发动机指示和机组警告系统(EICAS)上显示＇DOOR CLSD＇信息 EICAS parameter DOOR CLSD displayed

什么情况下绿色的 AVAIL 开关/灯变亮When will the green AVAIL switch/light illuminates?

在什么情况下＇APU SOV OPEN＇(关断活门打开)信息消失When will the APU SOV OPEN message removed?

在什么情况下＇APU START＇状态信息消失，START 开关/灯熄灭。When will the APU START status message is removed and the switch/light START indication extinguishes

当按下＇APU START/STOP＇(起动/停车)开关/灯，APU 达到 5%转速时When theAPU START/STOP switch/light is pressed, at 5% rpm:

在什么情况下状态页上显示＇APU START＇状态信息，START 灯变亮。When will the APU START status message appears on the status page and the START light on the switch/light illuminates?

判断正误：在地面上时，如果 APU 的转速超过 5%，或者空中飞行时，APU 转速超过 10%，那么 ECU 将抑制起动过程。True or False: If the APU is rotating above 5% RPM (on ground) or windmilling above 10% (in-flight) the ECU will inhibit start.
