如果对飞机能否安全着陆有怀疑，或在目视盘旋的同时失去了目视参考物，则应执行复飞程序。If there is a doubt as to whether the aircraft can land safely, or if visual reference is lost while visually circling, a missed approach procedure should be performed.

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.

在 APU 起动和运行过程中，同时需要 APU 电瓶和主电瓶工作。它们的最低电压是 _____ 伏直流电。Both the APU and main battery are required to start and operate the APU. The minimum battery voltage for both is _____ volts DC.

在飞行状态下，当 APU 转速下降到低于（）时，可以立即重新起动 APU(起动机重新接入系统)。In flight, an immediate restart (APU starter reenactment) can be initiated upon APU rpm rolldown below（）.

APU 起动机起动次数有严格的要求，一小时内最多起动____次或尝试起动。The APU starter motor duty cycle is limited to no more than ____ starts or start attempts in 1 hour.

APU 起动系统由直流起动机和一系列由 ECU 控制的继电器组成。起动系统的电源是: The APU start system consists of a DC starter motor and a series of relays that are controlled by the ECU. The electrical power source is:

APU排气温度(EGT)受以下参数影响:APU EGT is influenced by:

判断正误：当 APU 转速超过 50% 时，进气门完全打开。True or false: At APU rpm greater than 50%, the intake door is fully open.

判断正误：如果不知道 APU 进气门的位置，那么空速不得超过 220KIAS，或者 APU 必须保持运行状态。True or false: If the APU door position is unknown, airspeed is restricted to 220 KIAS, or the APU must remain in operation.
