Max Truscott: 我是航空新闻播客的主持人Max Truscott,我今天将讨论NTSB关于里根国家机场附近空中相撞事故的初步报告。这份报告揭示了该空域中存在的系统性风险,包括直升机与飞机之间的近距离相遇事件频繁发生。报告中还提到了系统性偏差的常态化,以及FAA在数据分析和安全管理方面存在的不足。我将分享报告中的关键信息,并播放NTSB主席Jennifer Homendy和交通部长Sean Duffy在新闻发布会上的讲话音频。 此外,我还将分析报告中关于机组人员经验、飞行数据记录器信息以及空中交通管制沟通等方面的内容。最终,我希望听众能够理解这起事故背后的系统性问题,并认识到主动报告危险和建立安全文化的重要性。 Jennifer Homendy: NTSB的初步报告显示,在过去几年中,DCA机场附近发生了大量的直升机与飞机近距离相遇事件。这些事件大多发生在飞机进近着陆时,并且其中相当一部分直升机可能高于规定的航线高度限制。我们发现,每月至少有一次TCAS(交通警报和防撞系统)的解决建议被触发,这表明存在严重的碰撞风险。我们还发现了系统性偏差的常态化现象,即由于长期以来没有发生严重事故,人们逐渐接受了这种风险。因此,我们建议永久关闭DCA机场附近4号直升机航线,并指定一条替代航线,以减少空中碰撞的风险。 Sean Duffy: 交通部对NTSB的初步报告表示关注,并已采取行动,限制直升机在DCA机场波托马克河上空的飞行。我们正在部署AI工具,以识别空域和机场中的热点区域,并采取预防措施。此外,我们将对美国的空中交通控制系统进行重大升级,包括使用光纤、无线和卫星技术,以及最新的雷达和终端设备,以提高安全性并减少延误。这将是一项大规模的投资,但我们认为这是必要的,以避免未来发生类似的悲剧。

Shownotes Transcript

The NTSB held a press conference to provide preliminary findings from the flight Max talks about new findings from the NTSB Preliminary Report on the midair collision over the Potomac River involving a U.S. Army Black Hawk helicopter and a PSA Airlines regional jet near Reagan National Airport (DCA). The episode features audio from NTSB Chairman Jennifer Homendy and DOT Secretary Sean Duffy, highlighting the systemic risks in the airspace.

)

The report reveals a history of frequent near-midair collisions at DCA, with 85 close encounters (under 200 feet vertical, 1,500 feet lateral separation) in the last two and a half years. A key issue is Route 4, where helicopters fly with only 75 feet of separation from aircraft on approach to Runway 33. The NTSB recommends closing Route 4 near DCA and establishing an alternative route.

The episode also discusses systemic normalization of deviance, where repeated near misses led to complacency. DOT plans major air traffic control upgrades, including AI monitoring for collision hotspots.

Max reviews details from the cockpit voice and flight data recorders, noting altitude discrepancies and miscommunications between ATC and the helicopter crew. He urges pilots to report hazards proactively, emphasizing that a culture of safety is critical to preventing future accidents.
