不少旅客都很喜欢坐在靠窗的位置欣赏窗外的风景，但飞机靠窗的座位有限并不是每个旅客都能如愿。当旅客按照登机牌上的信息坐在不靠窗的位置，而此时有空着的靠窗座位时，是不是可以随意自行换位呢？

Many passengers are very like to sit by the window position appreciate the scenery out of the window,But the plane seat by the window co., LTD., and not every passenger can fulfill a wish.When passengers boarding pass according to the information without sitting on the position of the window,When the window seat free when,If we can optional to transposition??

　　飞机的平衡指的是一架航空器的重心位置，它对飞机的稳定性、可控性以及飞行安全是极其重要的。

The plane balance refers to a frame aircraft center of gravity position,It to the stability of the plane/Controllability and flight safety is extremely important.

　　影响航空器的俯仰平衡的因素主要有旅客的座位安排方式和货物的装载位置及滚动情况、机上人员的走动、燃料的消耗、不稳定气流、起落架或副翼的伸展和收缩等。因此配载人员在安排旅客的座位时，除去按照舱位等级与旅客所持客票的票价等级一致来安排之外，在对重心影响较小的舱位尽量多安排旅客，并且在航空器起降时请旅客不要在客舱内走动，以免影响航空器的俯仰平衡和旅客的安全。

Influence of aircraft pitch balance are the major factors of the passenger seat arrangement way and the goods loading position and rolling conditions/Crew walking around/Fuel consumption/Unstable airflow/Landing gear or flap of stretching and contraction, etc.Therefore loading personnel in the arrangement of the passenger seat,Remove according to space level and the passengers of the ticket fare level consistent outside to arrange,In the center of gravity affect smaller space arrangement of passengers as much as possible,And in the aircraft takeoff passengers please don't walk about in the cabin,Lest affect aircraft pitch balance and the safety of the passengers.

　　每一个航班在起飞前，地面配载平衡部门都会根据旅客的人数和所装货物的重量，计算出飞机的平衡参数，将旅客合理分布在飞机的“某一座位上”，这“某一座位”就是旅客在机场值机柜台办理登机手续时领取的登机牌上所指定的座位号，而飞行人员则根据相关平衡参数来飞行。因此在飞行过程中，是不允许旅客擅自调换座位的，以免引起飞机失衡从而影响飞机操作性能而危及飞行安全。

Every flight before taking off,Ground loading balance department will be according to the number of passengers and cargo weight,Calculate the balance of the plane parameters,Will passengers reasonable distribution of aircraft"A seat",this"A seat"The passenger is at the airport check-in counter to check in for boarding pass at the designated seat number,And flight crew is according to relevant equilibrium parameter to fly.Therefore in the process of flight,Passengers are not allowed without authorization of the exchange seats,So as not to cause the plane imbalances which affect aircraft performance and endanger the flight safety.

　　温馨提醒：

Warm remind:

　　如果您对座位有要求，建议您可以提前去值机柜台办理登记手续，在换登机牌的时候向值机人员提出您的要求，一般情况下值机人员会按照您的要求为您选择座位。另外，当飞机起飞后，在不影响飞机安全飞行的前提下，向乘务员提出合理的换位要求也会得到满足。

If you have requirements for seats,Suggest you can advance to the registration formalities at the check-in counter,In the change of the boarding pass when check-in staff to put forward your request,Usually check-in staff according to your request for you to choose seat.In addition,When the plane took off,In does not affect the safety of the flight under the premise of flight,This paper puts forward reasonable transposition to attendant demands will be satisfied.
