FAA clears proposed Trump arch, requires 'eternal flame' to alert pilots

The FAA has cleared a proposed 250-foot triumphal arch near Arlington National Cemetery, finding it poses no hazard to aircraft but requiring an 'eternal flame' on top as a warning light. The arch, proposed by President Trump to mark the nation's 250th anniversary, is part of a broader plan to reshape Washington's monumental landscape. Veterans have sued to block the project, arguing it would destroy the historic sightline between the Lincoln Memorial and Arlington National Cemetery.

The Federal Aviation Administration has cleared a proposed 250-foot triumphal arch near Arlington National Cemetery, finding it poses no hazard to aircraft but requiring an 'eternal flame' on top as a warning light. The arch, proposed by President Trump to mark the nation's 250th anniversary, is part of a broader plan to reshape Washington's monumental landscape, including a new White House ballroom, renovation of the Lincoln Memorial Reflecting Pool, and redevelopment of a golf course in East Potomac Park. Veterans have sued to block the project, arguing it would destroy the historic sightline between the Lincoln Memorial and Arlington National Cemetery. The FAA determination requires the arch to be marked with a light on top and floodlight projectors pointed at it to make it noticeable for pilots. Some aviation experts have raised safety concerns given its proximity to Reagan Washington National Airport. The FAA previously said the arch would need red obstruction lights but said on Friday the structure no longer is required to have them. The FAA determination is subject to review if anyone petitions by October 18. In June, Senator Tammy Duckworth urged the FAA to reject White House pressure to approve the arch, citing potential risks to commercial flights. The proposed arch would be 3,000 feet from Washington National Airport and within the airport's main approach and departure corridor. The FAA said pilots must fly at least 780 feet above the area around the arch, at least 488 feet above the top of the proposed structure. On September 4, a federal judge ordered the Trump administration to give 48 hours' notice before engaging in any activity on the arch site, except for work to identify underground cultural artifacts.
