- The arch will require an "eternal flame" and lighting to alert pilots.
- The proposed arch is part of President Donald Trump's initiative to reshape Washington's monumental landscape.

- The FAA determination is subject to review if anyone petitions by October 18.
The Federal Aviation Administration (FAA) has determined that a proposed triumphal arch President Donald Trump intends to build near Arlington National Cemetery in Washington would not pose a hazard to aircraft. The structure will be required to feature an "eternal flame" and floodlight projectors to ensure visibility for pilots. Some aviation experts had previously raised safety concerns due to its proximity to Reagan Washington National Airport.
The FAA's decision removes a significant aviation-related obstacle for the arch, which is part of Trump's broader vision for reshaping Washington's monumental landscape. The project also includes plans for a new White House ballroom, renovation of the Lincoln Memorial Reflecting Pool, and redevelopment of a golf course in East Potomac Park.
However, veterans have filed lawsuits seeking to block the arch's construction, contending that it would disrupt the historic sightline between the Lincoln Memorial and Arlington National Cemetery. The FAA had previously indicated that red obstruction lights would be necessary, but on Friday stated these are no longer required. The FAA's determination remains subject to review if any party petitions against it by October 18.
In June, US Senator Tammy Duckworth, a key figure on the Senate aviation subcommittee, had urged the FAA to reject any White House pressure to approve the 250-foot (76-meter) arch, citing potential risks to commercial flights. The proposed arch is located 3,000 feet from Washington National Airport and falls within its primary approach and departure corridors. Typically, buildings over 200 feet near airports require blinking red warning lights, similar to the Washington Monument. Duckworth also noted that construction would involve cranes reaching 300 to 320 feet and could operate up to 20 hours daily for two to three years. The FAA has stipulated that pilots must maintain an altitude of at least 780 feet above the arch's vicinity and 488 feet above the structure itself. Earlier, on September 4, a federal judge had ordered the Trump administration to provide 48 hours' notice before commencing any work on the arch site, with the exception of identifying underground cultural artifacts.
