近日，一架西南航空的波音737客机在准备降落克利夫兰霍普金斯国际机场时，因一架医疗直升机在其前方同一高度飞行，被迫中断降落并进行复飞。飞行数据显示，两架飞机在约2075英尺的高度，相距约半英里。空管塔台记录显示，直升机飞行员曾收到指示，要求其飞越并经过西南航空客机前方。西南航空机组人员收到TCAS RA（交通碰撞避免系统分辨率建议）后，执行了复飞程序，并在安全绕飞后成功着陆。美国国家运输安全委员会（NTSB）已派出调查组介入此事，调查两架飞机之间发生的“分离丢失”事件。此次事件也再次引发了对当前因政府关停导致空中交通管制系统压力增大的担忧。

✈️ **迫降复飞事件**：一架西南航空的波音737客机在克利夫兰进行降落时，因一架医疗直升机出现在其前方同一高度，机组人员收到了TCAS RA警报，被迫中断正常降落程序，执行了复飞操作。此举是为了避免潜在的空中碰撞风险，确保飞行安全。

🚁 **近距离接触细节**：根据Flightradar24的数据，事发时直升机在西南航空客机前方约半英里处，两机均在2075英尺的高度飞行。空管塔台的录音显示，直升机飞行员曾被指示“最好能飞到它上面并从前面通过”，但随后西南航空客机因TCAS RA指令而转向，并告知需要进行复飞。

🚨 **NTSB介入调查**：美国国家运输安全委员会（NTSB）已确认派遣调查团队前往事发地，对此次“分离丢失”（loss of separation）事件进行深入调查。分离丢失是指两架飞机之间的距离小于安全要求的最小距离，这可能导致严重的空中危险。

⚠️ **空管系统压力**：此次事件发生在政府关停背景下，导致空中交通管制员面临无薪工作和因病缺勤率上升等问题，使得空管系统承受巨大压力。虽然此次事件未造成人员伤亡，但其潜在风险和与年初DC发生的致命直升机撞击事件的相似性，再次凸显了保障空域安全的重要性。

A Southwest flight had to abort its landing after a close call with a helicopter.The NTSB said it's sending a team to investigate Wednesday's incident.It comes as the government shutdown has increased pressure on the air traffic control system.

Investigators are looking into a close call between a Southwest Airlines flight and a helicopter that forced the plane to abort its landing and go around.

Southwest Flight 1333, from Baltimore, was on approach to Cleveland Hopkins International Airport last Wednesday.

At the same time, an Airbus H145 medical helicopter was en route to pick up a patient from a hospital in the city.

Flightradar24 reported that the Boeing 737 received a traffic collision avoidance system resolution advisory, or TCAS RA, an instruction that tells the pilots how to move out of the way.

Flight-tracking data shows how the helicopter passed about half a mile in front of the airliner, both at an altitude of 2,075 feet.

An audio recording from the air traffic control tower shows controllers instructing the helicopter to pass behind the Southwest plane.

"Sir, it'd be better if we go above it and in front of it, if we can?" the helicopter pilot replies.

The Southwest plane then turns right, and the pilot tells the controller they need to go around as they received the TCAS RA.

It circled around the airport before landing safely, data from Flightradar24 shows.

In a Saturday post on X, the National Transportation Safety Board said it was sending a team to investigate.

It added that the two aircraft experienced a loss of separation, meaning they came closer to each other than the required minimum safe distance.

A Southwest Airlines spokesperson said the "pilots discontinued their initial approach to the runway due to the presence of another aircraft."

"Southwest appreciates the professionalism of our Crew in responding to the situation. We are engaged with the [NTSB] and will support the investigation," they added. "Nothing is more important to Southwest than the safety of our customers and employees."

The incident came as the country's air traffic control system is in the spotlight amid the government shutdown.

Air traffic controllers aren't being paid during the shutdown, but must still come to work due to their critical role. As the shutdown drags on, more of them are calling off sick.

Staffing shortages have prompted flight delays at numerous airports since the shutdown began on October 1.

"The shutdown must end so that these controllers receive the pay they've earned and travelers can avoid further disruptions and delays," the Federal Aviation Administration said on Friday.

The Cleveland incident, although it ultimately didn't lead to a collision or any injuries, bears similarities to a deadly crash that occurred in January of this year.

On January 29, 67 people died after an American Airlines flight coming in to land at Reagan National Airport collided with an Army Black Hawk helicopter over the Potomac River in Washington, DC.
