A. 在燃油箱内提供正气压。Provide positive air pressure in the fuel tanks.

B. 平衡燃油箱内压力。Equalize pressure in fuel tanks.

C. 使空气在油箱内流动以防止爆炸性气体混合。Cause air to flow through fuel tanks to prevent explosive gas mixtures.

D. 没什么作用。油箱在飞行中密封，以防止燃料在高海拔的低气压下蒸发。Do nothing. Tanks are sealed in flight to prevent fuel from evaporating in low atmospheric pressures at high altitudes.

禁止根据TCAS TA 信息进行避让机动飞行。It is forbidden to execute avoidance maneuver according to TCAS TA information;

（案例分析）某航班在上客快结束时EFB收到舱单后一直无法签收，机长认为是机场信号接收问题，移动位置可能好一点,为保障航班正常，申请正常推出后尝试签收。飞机滑出上跑道后机长电话告知AOC电子舱单无法签收，航班滑回，你认为机长的决策是否正确？(Case analysis) A flight crew received loadsheet on EFB when the passenger boarding were to be completed soon, but it could not be signed, the captain thought the problem resulted from signal receiving, it could be improved by moving the aircraft to another place. For guaranteeing flight nomality, the flight crew requested a normal push-back and then had another try on signing. After the aircraft taxied out and entered runway, the captain informed the AOC by phone that the electronic loadsheed could not be signed, and the plane would taxi back. Do you think the captain＇s decision was correct and why?

机长在得到开车指令之后，应立即关闭舱门，舱单只要在起飞前确认即可。After getting the clearance of engine start, the captain shall close the door immediately, the load-sheet can be confirmed before takeoff.
