空中旅行需求到2050年几乎翻一番,但跑道短缺限制了增长,尽管空中交通系统有所改善。 Air travel demand to nearly double by 2050, but runway shortages limit growth despite improved air traffic systems.

在亚太和非洲增长的推动下,预计到2050年全球航空旅行需求将增加近一倍,达到94亿乘客。 Global air travel demand is projected to nearly double to over 9.4 billion passengers by 2050, driven by growth in Asia-Pacific and Africa. 虽然空中交通管理的进展——包括卫星导航、ADS-B、RVSM和AI增强的系统——提高了飞行的效率和安全,但最大的瓶颈仍然是跑道能力。 While advancements in air traffic management—including satellite navigation, ADS-B, RVSM, and AI-enhanced systems—have improved in-flight efficiency and safety, the biggest bottleneck remains runway capacity. 尽管空气空间系统现代化,但所有飞机都必须在有限的跑道空间降落,使地面基础设施成为对系统扩展的主要限制。 Despite modernized airspace systems, all aircraft must land on limited runway space, making ground infrastructure the primary constraint on system expansion. 建造新的跑道是必要的,但常常被忽视。 Building new runways is essential but often overlooked.
