虽然全球航空运输业2008年的重大事故总数较前两年有所增加,但事故生存率却得到了提升。科技的进步,法规的完善,确实已经明显地提升了全球航空安全水平。但从最近几年的统计结果来看,全球航空运输业似乎在安全运营上遇到了瓶颈问题:从1999年以来,每年的重大飞行事故总数并没有像几年前一样,表现出持续下降的趋势,而是在波峰和波谷之间不断震荡。 Although the total number of major accidents in the global air transport industry in 2008 increased from the previous two years, the accident survival rate has been raised. The advancement of science and technology and the improvement of laws and regulations have indeed obviously raised the level of global aviation safety. However, judging from the statistical results in recent years, the global air transport industry seems to have encountered a bottleneck in its safe operation. Since 1999, the total number of major aviation accidents each year has not shown a steady downward trend as it was only a few years ago , But in the peak and trough between the constant shock.
