一个被称做是“自由飞行”的革命正要取代美国现在的空中交通管制系统。此次革命的倡议者表示,这不仅能减少延误而且每年可以为民航业节省数十亿美元。“自由飞行”,顾名思义,飞行员可以依其需要起飞并沿最适合的航路飞至目的地,只要飞行员在飞行时不挡住其他飞行员的道路,空中交通管制(ATC)——改革者们称为空中交通管理(ATM)——不必发布任何指示。 A revolution known as “free flight” is replacing the current U.S. air traffic control system. Proponents of the revolution say it will not only reduce delays but also save billions of dollars a year for the airline industry. “Free flight”, as the name implies, allows pilots to take off and fly along the most suitable route to their destination as long as pilots do not block the paths of other pilots while in flight. ATC (Air Traffic Control) Traffic Management (ATM) - Do not post any instructions.
