华盛顿3月31日 路透社报道——美国联邦航空局周二表示，将对旧金山国际机场实施新的安全限制措施，此举将限制部分航班降落，并导致严重延误。
美国第13繁忙机场将因跑道重铺工程以及该局禁止航班在晴朗天气下并行降落旧金山东西向平行跑道的决定而出现延误，联邦航空局表示。

联邦航空局称，两项措施将把最高起降速率从每小时54架次降至36架次，并补充称跑道重铺工程完成后，该局并不计划解除这些限制。
该机场的跑道工程将使两条南北向跑道停用约六个月。
旧金山国际机场在一份声明中表示，这些调整将导致航班延误。
此前该机场预计约15%的航班会因跑道工程延误，但现在预计延误情况将加剧，约四分之一的抵港航班可能出现至少30分钟的延误。

联邦航空局表示，目前正在要求“交错进场，即一架飞机与平行跑道上的飞机保持偏移”。
该局称，此前在恶劣天气下从未允许并行进场，并补充称正在探索安全提升该机场抵港速率的方法，同时已采取多项措施降低因目视间隔问题引发事故的风险。
联邦航空局本月早些时候表示，将收紧直升机安全规则，并暂停在大型机场附近使用飞机与直升机之间的目视间隔规则。
这一举措是在2025年1月美国航空（AAL.O），将在新标签页打开 一架支线客机与陆军直升机相撞造成67人死亡的空中相撞事故之后出台的。

WASHINGTON, March 31 (Reuters) – The U.S. Federal Aviation Administration said on Tuesday that it was imposing new safety restrictions at San Francisco International Airport that will limit some landings and lead to significant delays.
The 13th-busiest U.S. airport will experience delays due to a runway repaving project and the agency’s decision to prohibit flights from making side-by-side approaches to San Francisco’s parallel east-west runways in clear weather, the FAA said.

The two measures will reduce maximum rates from 54 flights per hour to 36, the FAA said, adding it does not plan to lift the restrictions once the runway repaving is completed.
The airport’s runway project will put the two north-south runways out of service for approximately six months.
San Francisco International Airport said in a statement that the changes would result in flight delays.
While the airport previously forecast about 15% of flights to be delayed by the runway project, it now expects the change to increase the potential for delays to about a quarter of arriving flights experiencing a delay of at least 30 minutes.

United Airlines (UAL.O), opens new tab accounts for about half of the passenger traffic at San Francisco, followed by Alaska Airlines (ALK.N), opens new tab with about 10%. United said the planned runway construction may cause flight delays.
The FAA said it is now requiring “staggered approaches, with one aircraft offset from the aircraft on the parallel runway.”
It said it had never allowed side-by-side approaches in bad weather, adding that it was exploring ways to safely increase the airport’s arrival rate and had taken a number of steps to reduce the chances of accidents due to visual separation issues.
The FAA said earlier this month it was tightening helicopter safety rules and would suspend use of visual separation between airplanes and helicopters near major airports.
This follows the January 2025 mid-air collision between an American Airlines (AAL.O), opens new tab regional jet and an army helicopter that killed 67 people.
The FAA cited two recent incidents in issuing the new rules, including a near miss involving an American Airlines flight and police helicopter near the San Antonio airport.
