The FAA and U.S. Coast Guard disagree on the safety of the airspace near Ronald Reagan Washington National Airport (KDCA) in D.C. following major changes the regulator recently implemented.
The FAA in January published an interim final rule that would permanently restrict nonessential helicopter and powered-lift aircraft operations in certain areas near KDCA, building on updates it made to the airport’s helicopter routes and zones in October. For example, helicopter Route 3 over the Wilson Bridge—which intersected the route that planes use to approach the airport’s runway 1—was replaced by the Bridge Creek Transition, a less direct route further from fixed-wing traffic.
Three members of the Coast Guard, speaking during a Transportation Research Board (TRB) meeting earlier this month, said the agency failed to adequately roll out these changes, which they said actually raise the likelihood of a collision between helicopters.
The FAA implemented the changes to deconflict helicopter and fixed-wing traffic after the fatal January 2025 collision between a U.S. Army Black Hawk and commercial airliner over the Potomac River. The National Transportation Safety Board (NTSB) has since issued a laundry list of recommendations, several of which the FAA in May said it adopted.
“It wasn’t mitigating the overall risk, it was just transferring that risk elsewhere,” said Commander Nate Rhodes, a senior Coast Guard pilot assigned to the national capital region (NCR) air defense facility that is tasked with safeguarding the skies over Washington, D.C.
Commander Blake Morris, another Coast Guard pilot assigned to the NCR air defense facility, said some changes to the airport’s helicopter routes were a “big surprise” to the branch. He added that they make the airspace “probably the most complex that I’ve operated in.”
The FAA, though, flatly denied that assertion.
Commander Mike Freeman, the Coast Guard’s chief of aviation safety, said the unit’s helicopters recorded six serious near-collisions in the NCR between 2015 and ’25, four of them with other helicopters. The FAA by contrast said it has received zero reports of near-midair collisions involving military helicopters in the KDCA airspace since 2023, but there were 10 involving helicopters in that airspace from 2017 through ’22.
The regulator said the Coast Guard’s claims are “not supported by the data.” It further emphasized that no military agency commented to express concerns with the interim final rule published in January.
“Following the January 2025 midair collision, the FAA took decisive action to improve safety around DCA for the flying public,” the agency said in a statement. “We restricted mixed traffic around the airport and implemented permanent helicopter route changes that addressed an NTSB safety recommendation—actions the NTSB has publicly praised.”
Per The Air Current, one unnamed FAA official said after the TRB meeting that helicopters faced more conflicts in KDCA airspace prior to the recent changes.
“They have the whole rest of the U.S. to fly,” the official reportedly said. “If they can’t separate themselves from the whole rest of the national airspace system, they just need this two miles around the airport to make themselves safe, then there’s something wrong with the way the system is operating.”
Rhodes said the airspace changes have disrupted Coast Guard training flights in the NCR that are designed to ensure “that we’re proficient in the area and flying in the area.”
“I brought these [concerns] up to our Coast Guard FAA rep, and I’ve also brought them up on the [FAA’s safety risk management] panels as well,” he said. “And I know a number of other operators have voiced similar concerns.”
In a statement to The Air Current, Captain Scott Austin, commanding officer of Coast Guard Air Station Atlantic City in New Jersey, said the branch “has been working collaboratively with the FAA on iteratively improving airspace changes based on our concerns for months.”
What’s New?
Facing political pressure and public scrutiny, the FAA implemented several changes at Reagan Airport in the past several months.
In October, the regulator updated the airport’s helicopter routes and zones, with the big changes being the shift from helicopter Route 3 to the Bridge Creek Transition and the shrinking of two operating zones.
In March 2025, it banned the use of visual separation between helicopters and fixed-wing aircraft within five miles of the airport and permanently closed helicopter Route 4, where the Black Hawk collided with the passenger jet in ’25. It also updated its agreements with the military regarding the required use of ADS-B Out broadcasting.
This past March, an FAA general notice extended the visual separation limitations to airports nationwide. However, lawmakers continue to debate two bills calling for broader ADS-B Out equipage—one that would require it for the military, and one that would not.
The NTSB in the wake of the January 2025 collision further recommended mandatory ADS-B In equipage and a transition to more modern airborne collision avoidance system X (ACAS X) platforms. It also required the Army to review its helicopter route charts and determine whether further modifications may be needed to safely deconflict helicopter and fixed-wing traffic at KDCA.
Investigators determined that ineffective sharing of helicopter training route data between the FAA and aircraft operators resulted in those routes being placed in close proximity to KDCA approach. They also found that the Army failed to alert pilots to the error tolerance of the Black Hawk helicopter’s barometric altimeter, which led the crew of the accident helicopter to surpass Route 4’s maximum published altitude.
Though federal officials have lauded the recent changes’ impact on safety, Rhodes said that “some of them are good, but some of them have made things more challenging.”
Coast Guard Disagrees With FAA
Chief among the Coast Guard’s concerns is that the October charting revisions pushed helicopters out of KDCA airspace and into more concentrated operating zones. Rhodes said that “increased the risk” of collisions “because it’s actually far harder to spot another helicopter flying in the area…than it is an airliner.”
“They’re big and very bright, and they’re actually on set paths,” he said.
According to the FAA, the “reported concern about avoiding other helicopters in visual flight conditions underscores exactly why” the agency moved rotorcraft from Route 3 to the Broad Creek Transition. But per Rhodes, the decision actually created more ambiguity since helicopters are no longer flying above a roadway.
“You both just move to the right of the road, and it’s easy to cross,” he said of the old route over the Wilson Bridge.
Rhodes added that “there is almost a 90-degree turn” on the Broad Creek Transition, “which really isn’t feasible” for rotorcraft.
“And then if you’re transiting west to east, it’s forcing you to descend lower—even after you cross the river under the approach quarter—into rising terrain there on the other side of the river,” he said.
Rhodes said air traffic controllers’ (ATC) adjustment to the new routes has raised further confusion. He said that on KDCA’s helicopter Route 1, which still appears on aeronautical charts, “we’ve had a crew told—when they switched controllers—that they weren’t allowed to be on that route anymore, even though they were previously cleared for it.”
According to Rhodes, the FAA conducted SRM panels in 2025 through the lens of risk to commercial airlines and did not use controlled flight into terrain (CFIT) data when assessing changes to KDCA’s helicopter routes.
“I don’t think any of the CFIT hazards were looked at,” he said. “On some of the panels I was like, ‘Can we bring CFIT data into that?’ And they were like, ‘Well, we don’t have that.’”
An unnamed FAA official told The Air Current that SRM panels are “designed to discuss implementation, not airspace designs.”
“It seems like a lot of what was being pushed was mitigating the risk between commercial airliners and helicopters,” Rhodes said of the discussions. “I do think there are changes that can be implemented to make things safer overall for everyone. But that’s going to require just looking at the entirety of the risk and not just trying to shift it from one side to the other.”
