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.

APU驱动的附件包括The APU driven accessories include:

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.
