Officials claim the move will eventually have an impact on overall weight and fuel efficiency of the aircraft, although clearly the decision will also remove expensive printing costs.
新航有关管理人员表示此举既可减少昂贵的印刷费用，而且也可降低飞机整体载重和提高燃油效率。
On really long flights, fuel can account for 40% of a plane's take-off weight, so that around 20% of the fuel is used to carry the rest of the fuel.
在特别长的飞行时，燃料可以占到飞机起飞重量的40%，所以大约有20%的燃料时用来运输其它燃料的。
In this way, new forms of carbon will reduce aircraft weight, subsequently cutting the burning of fuel and dumping of carbon in the atmosphere.
由此途径，新型碳会减轻飞机重量，从而减少油耗和碳排放。
