1994年,全民航全年共运输货邮82.94万吨,是1979年的15.5倍。货邮运输总周转量达18.6万吨公里,占全国民航运输总周转量的31.8％,这样的规模与我国运输飞机的运载能力(1994年全民航运输机平均载运率为56.8％)相比表明,航空货运的发展远远未能适应运载能力的增长,客机的货舱利用率不高,客机的带货潜力未能充分发挥。同时,由于我国航空货运的货源具有较大的不稳定性和明显的单向性特点,专用货机的大量使用受 In 1994, the entire airline flew 829,400 tons of cargoes a year, 15.5 times that of 1979. The total turnover volume of cargo and mail transport reached 186,000 tons, accounting for 31.8% of the total civil aviation transportation volume. Compared with the carrying capacity of China's transport aircraft (the average carrying capacity of all civil aircraft carriers was 56.8% in 1994), this scale shows that aviation, The development of freight transport is far from being able to meet the growth of carrying capacity. The cargo hold utilization rate of passenger planes is not high, and the potential of cargo carrying aircraft is not fully demonstrated. At the same time, due to the large instability and obvious unidirectional characteristics of the cargo sources of China's air cargo, the extensive use of special freighters is affected by
