关于飞机使用电气源勤务

yeh999

CAUTION:       
DURING PRE-CONDITIONING WITH THE GROUND-AIR SUPPLY UNIT, MAKE SURE THAT THE ELECTRICAL GROUND POWER UNIT IS ON AND CORRECTLY CONNECTED TO THE AIRCRAFT. IF YOU DO NOT OBEY THIS PRECAUTION, THE RECIRCULATION FANS CAN STOP OPERATION AND DAMAGE TO THE AIRCRAFT CAN OCCUR.
接地面空调里面的CAUTION就给了解释
不供电 再循环风扇会停止运行 对飞机造成损坏
关于先断空调再断电源也是同一个道理吧 但是撤地面电源手册并没有写要先撤空调、气源

如果是高压气源的话
WARNING:       
MAKE SURE THAT DURING THIS PROCEDURE THE AIRCRAFT IS IN ONE OF THESE THREE CONDITIONS:
THE CABIN PRESSURE OUTFLOW VALVE IS OPEN.
确保OFV打开 头顶面板OFV正常位就是打开的
