目前,我国已跨入世界航空大国的行列,但距航空强国还有较大差距,人均水平还比较低。从总量上看,我国运输机场的总量仅为美国(可供大于5.7吨、30座以上飞机起降的商用定期航班机场,2003年为628个)的约1/5,运输飞机数量约为美国的1/10,航空运输总周转量和旅客运输量约为美国的1/5 At present, our country has stepped into the ranks of the world’s aviation big powers, but there is still a long way to go before the powerful air powers, with per capita GDP still relatively low. In total, the total number of transport airports in China is only about 1/5 of that of the United States (for commercial scheduled airports that take off and land more than 5.7 tons and 30 or more, up from 628 in 2003), the number of transport aircraft is about 1/10 of the United States, the total volume of air transport and passenger traffic is about 1/5 of the United States
