飞机高度等于或者高于航图公布的复飞高度时，能否使用TO/GA模式？Can the T0/GA mode be used when the aircraft altitude is equal to or higher than the missed approach altitude published in the aeronautical charts?

以下哪个是APU主要部件组成。Which of the following is major component of APU:

以下哪个是APU主要部件组成。Which of the following is major component of APU:

判断正误：高温滑油在 APU 空气/滑油热交换器内，通过 APU 进气管路提供的部分空气进行冷却。True or False: Oil is cooled in the APU air/oil heat exchanger, with airflow provided by the APU intake duct.

判断正误：在地面，如果滑油压力电门失效，ECU 将使 APU 停车。True or false: The ECU will shut down the APU ifOil pressure switch failed on the ground.

判断正误：在地面或在飞行中，如果转速传感器信号失去，ECU 都将使 APU 停车。True or false: The ECU will shut down the APU if loss of speed sensor signals on the ground or in flight.

判断正误：在地面或在飞行中，如果APU 舱门不能在指令30秒内打开，ECU 都将使 APU 停车。True or false: The ECU will shut down the APU if APU door failed to open within 30 seconds of command on the ground or in flight.

判断正误：在地面或在飞行中，如果APU直流电源丢失，ECU 都将使 APU 停车。True or false: The ECU will shut down the APU if APU lost DC power on the ground or in flight.

判断正误：在地面或在飞行中，如果APU超速，ECU 都将使 APU 停车。True or false: The ECU will shut down the APU if APU overspeed on the ground or in flight.

如果APU 喘振活门关闭，APU操作高度须低于（）。If APU surge valve closed, APU operation altitude shall be below ( )

用于在驾驶舱外关闭APU的APU SHUT−OFF电门位于飞机哪个位置？Where is the APU SHUT−OFF switch located in the airplane to shut down APU from outside of cockpit?
