美国交通部长近日在接受路透社专访时透露，已正式向国会提请100亿美元专项资金，用于启动下一代空中交通管制系统的大规模升级计划。这项雄心勃勃的改造工程被视为近三十年来美国航空基础设施最重大的变革。
据悉，该笔资金将主要用于部署基于卫星导航的先进航管技术，逐步取代沿用数十年的地面雷达系统。新系统预计能提升40%的空域容量，同时通过优化航路减少航班延误现象。分析指出，这项升级将惠及达美航空、联合大陆航空及西南航空等主要承运商，有望降低其运营成本并提升准点率。
目前美国国会已就该提案展开初步讨论，两党议员均承认现有航管系统存在老化风险，但在资金分配和实施进度上仍存分歧。若拨款顺利通过，首批升级设备将于2026年在东西海岸主要空域投入测试。
