Part 1 is preface , dealing with the importance of strategy study for the mro as well as for gameco 阐述发展战略研究对于本行业特别是本企业的意义。第二部分，民用飞机维修行业特点与现状。
The ways provided by this paper is instructive to constitute successfully a computer system of maintainability evaluation and validation of airplane 本文提供的方法对于成功构建民用飞机维修性评估与验证的计算机系统具有指导意义。
For civil airplane , the good or the bad of its maintainability will directly affects its whole life costs and affects its competition in the market 对于民用飞机，其维修性的好坏将直接影响其全寿命周期费用，也将影响其市场竞争力。
Super - duralium that is widely used for the longerons , frames , stringers of military and civil aeroplanes , is an important aeronautic material 超硬铝合金是重要的航空结构材料，广泛用于军用飞机和民用飞机的大梁、桁条、隔框等承力部位。
Method of evaluation and validation of civil aircraft maintainability is studied in the paper from quantitative view , the research of this paper includes three questions . 1 本文从定量的角度研究民用飞机维修性的评估与验证方法，主要研究和解决了三个方面的问题： 1
" the reason for the delay is we do n ' t have a direct flight from skopje to london , and we did n ' t want to risk sending this kind of material with a commercial plane 他说： “行期之所以一拖再拖，是因为斯科普里没有直飞伦敦的航班，而且我们也不想冒险通过民用飞机来运送。
This paper firstly put forward maintainability qualitative parameters being the same with civil airplane based on traversing maintainability qualitative parameters of warplane 本文在详细研究军用飞机维修性定性指标体系的基础上，提出了适用于民用飞机的维修性定性指标体系。
3 . apply random net and neural net to evaluation and validation of civil aircraft maintainability , validate maintenance time of aircraft lighting system and landing gear system 将随机网络和bp神经网络应用于民用飞机维修性的评估与验证中，较好地验证了飞机照明系统和起落架系统的维修时间。
Now in our nation the system of maintainability parameter and value suited in warplane , a whole and feasible the system of civil aircraft is offered in the paper . 2 目前我国飞机的维修性参数指标体系大多数是针对军用飞机的，本文提出并建立了一套完整的、相对可行的民用飞机的维修性参数指标体系。
Under heavy security and before hundreds of cameras , the airbus a380 , the world ' s largest passenger aircraft , made a relatively quiet landing on the runway at jfkinternationalairport in new york 在重重保卫和成百个摄像机镜头前，空客a380 ，世界上最大的民用飞机，在纽约肯尼迪机场的跑道上安静地降落。
