天气状况是如何通过影响气流来提高编队飞行的效率的,这点仍有待观察。
It might also be hard for airlines to co-ordinate the departure times and destinations of passenger aircraft in a way that would allow them to gain from formation flight.航空公司可能也很难协调客机的起飞时间和目的地,使它们能够从编队飞行中获益。
Earlier this year the country's Defense Advanced Research Projects Agency announced plans to pay Boeing to investigate formation flight, though the program has yet to begin.今年早些时候,美国国防高级研究计划局宣布将计划出资,请波音公司研究编队飞行,不过该计划尚未启动。
