解析：这道题考察的是根据指示操作开关的能力。正确答案是B: 当灯亮起时，将开关设置为正常。这句话的意思是当灯被点亮时，你需要把开关设置为正常。选项A中的“goes off”表示灯熄灭，与题目中的“comes on”相反，所以不是正确答案。选项C中的“extinguished”也表示灯熄灭，与题目中的“illuminated”相反，所以也不是正确答案。
举个生动的例子来帮助理解：想象你在一个房间里，有一个开关控制着房间里的灯。当你看到灯亮起时，你需要把开关设置为NORMAL，这样灯就会保持亮着。所以正确答案是B。

解析：这道题是关于系统去能化的问题。De-energize意味着去能化，也就是移除系统的电力。所以正确答案是C。
让我们通过一个生动有趣的例子来帮助你更好地理解这个概念。想象一下你的手机是一个系统，它需要电力才能正常工作。当你想要关闭手机时，你会按下电源按钮，这样手机就会De-energize，也就是移除电力，手机就会关闭。在这个例子中，De-energize就相当于移除手机的电力，让手机关闭。
A. The actuator receives a hydraulically controlled mechanical command from FCC who sends an electrical commands and the aileron and the elevator power control units(PCU) will carry out this command.
B. FCC sends an electrical order to autopilot actuator. The actuator converts it to a hydraulically controlled mechanical command. The aileron and the elevator power control units(PCU) will carry out this command.
C. FCC sends an electrical commands to autopilot actuator. The actuator receive it to a hydraulically controlled unit . The aileron and the elevator power control units(PCU) will carry out this command from hydraulically controlled unit.
A. Pilots have more opportunity to move stabilizer to nose up position during takeoff thanks to the mach trim actuator who commands elevator to a more nose down position.
B. During takeoff, pilots have more opportunity to move elevator to nose up position thanks to the mach trim actuator who commands stabilizer to a more nose down position.
C. During takeoff, pilots have more opportunity to move elevator to nose down position thanks to the mach trim actuator who commands stabilizer to a more nose up position.
A. This is the maximum portion of flammable vapors in air. If the portion is bigger, when an ignition source touched the gas, it would cause the fire to be diffused.
B. This is the minimum volume of flammable vapors. If the volume is lower, when the gas contacted with an ignition source, the fire would not come out.
C. This is the minimum density of flammable vapors in air. If the density was lower, when an ignition source touched the gas, it would not cause the spread of flame.
A. If you don＇t do the OVHT/FIRE test, there is no indication of single loop operation in the flight compartment.
