华盛顿4月21日电（路透社）——美国运输部长肖恩·达菲表示，他正寻求国会拨款100亿美元，用于美国老化空中交通管制系统现代化改革的下一阶段工作，以减少系统性航班延误。
去年，国会为该项目拨款125亿美元，用于更换过时技术并补充人手不足的空中交通管制塔台人员。达菲在接受路透社采访时表示，此次新提案中的大部分资金将用于开发新软件，以大幅提升航空旅行效率。

“真正的核心突破在于空域管理软件，”他说道。
美国联邦航空管理局（FAA）的空中交通电信系统近期遭遇了一系列故障，包括去年导致纽瓦克机场大面积瘫痪的严重中断事件。此前的125亿美元拨款是在数十年的机场拥堵和航班延误投诉后拨付的，这些问题在很大程度上源于技术陈旧和塔台人员不足。
今年3月，由于技术老化问题，FAA两次被迫暂停华盛顿地区三座机场的所有航班，每次停运时长超过一小时。
达菲已申请更多资金用于塔台升级和地面态势感知技术。他此前曾表示需要额外190亿美元，此次仅向国会申请其中的100亿美元。

航空公司通常会安排超出FAA容量的航班量。达菲指出，他可以提前45天查看航班计划，发现其中有50%的航班量超出了系统承载能力。
新软件将帮助FAA调整航班安排以避免延误。“这个工具可以让我们提前掌握情况，进而合理分散航班，大幅减少延误，”达菲说，“我们能够解决这个问题。”
2023年的一份报告显示，FAA的通信系统已经过时多年，许多系统已无法获取备件。另一份报告指出，在FAA的138套空中交通管制电信系统中，有51套已无法持续运行。
在周二的一场活动中，达菲表示，FAA已经更换了近50%的铜线，完成了全国270个无线电基站的改造，在54个机场安装了新的地面态势感知系统，并将17个塔台升级为电子飞行条。
“重建我们航空系统的基础设施对美国来说并非不可能，我们完全可以做到，”达菲在航空行业活动上对听众说。
FAA表示，到2028年底，各机场将新增5000个基于光纤、卫星和无线技术的高速网络连接，27000台新无线电设备以及612套最先进的雷达系统。

US transportation secretary seeks $10 billion for air traffic control overhaul

WASHINGTON, April 21 (Reuters) – U.S. Transportation Secretary Sean Duffy said he was seeking $10 billion from Congress for the next phase of a massive effort to modernize America’s aging air traffic control system and reduce systemic flight disruptions.
Last year, Congress awarded $12.5 billion for the project to replace outdated technology and boost understaffed air traffic control towers. Much of the new proposed spending is to develop new software that could help make air travel much more efficient, Duffy told Reuters in an interview.

“The real magic truly is the software to manage the airspace,” he said.
The FAA’s air traffic telecom system has been hit by a series of failures, including serious outages covering Newark airport traffic last year. The initial $12.5 billion followed decades of complaints over airport congestion and flight delays due in large part to creaky technology and understaffed towers.
The FAA in March was twice forced to halt all traffic to the Washington area’s three airports for more than an hour because of issues with aging technology.
Duffy has requested more money for tower improvements and surface awareness technology. He has previously said he wants $19 billion more, but is asking Congress for $10 billion of that total.

Airlines often schedule traffic in excess of FAA capacity. Duffy noted he can look out 45 days and see schedules 50% above capacity.
New software would allow the FAA to move flights to avoid delays. “This tool lets us see and then spread flights in a way that allows for way less disruption,” Duffy said. “We could fix this.”
A 2023 report said the FAA’s communications system has been outdated for years and it can no longer get spare parts for many systems. Of the FAA’s 138 air traffic control telecoms systems, 51 were unsustainable, a separate report said.
At an event on Tuesday, Duffy said the FAA has already replaced nearly 50% of all copper wires, converted 270 radio sites nationwide, installed new surface awareness systems at 54 airports and transitioned 17 towers to electronic flight strips.
“Rebuilding the infrastructure of our aviation system is not too big for America. We can actually get this done,” Duffy told an aviation audience.
The FAA said by the end of 2028, airports will have 5,000 new high-speed network connections on fiber, satellite and wireless, 27,000 new radios and 612 state-of-the-art radars.
