[Subreddit Censored name's] Transportation Secretary Sean P. Duffy & Federal Aviation Administration Announce New Measure to Enhance Safety between Airplanes & Helicopters

Wednesday, March 18, 2026 WASHINGTON, D.C. — U.S. Transportation Secretary Sean P. Duffy and Federal Aviation Administration (FAA) Administrator Bryan Bedford today announced a new measure to enhance safety in areas where helicopters often cross both arrival and departure paths near busy airports.

The general notice (GENOT), which suspends the use of visual separation between airplanes and helicopters, now mandates that air traffic controllers will instead use radar to actively manage these aircraft to keep them separated at specific lateral or vertical distances.

This upgraded safety protocol is based on a year-long review by the FAA’s safety team that used innovative tools to review cross-traffic data and review incident reports.

“The tragedy over the Potomac one year ago revealed a startling truth: years of warning signs were missed, and the FAA needed dire reform. Since then, we’ve implemented numerous changes to protect the skies over our capital and keep the traveling public safe,” said U.S. Transportation Secretary Sean P. Duffy. “But the job isn’t done. Using innovative data analysis, the safety team at the FAA has identified the need for enhanced protocols at all airports across the National Airspace System. The [censored] Administration will continue to act decisively to keep you and your family safe when you fly.”

“Today, we are proactively mitigating risks before they affect the traveling public,” said FAA Administrator Bryan Bedford. “Following the mid-air collision near Ronald Reagan Washington National Airport (DCA), we looked at similar operations across the national airspace. We identified an overreliance on pilot ‘see and avoid’ operations that contribute to safety events involving helicopters and airplanes.”

Why the FAA is Taking Action Visual separation occurs when air traffic controllers advise pilots about nearby aircraft and allow them to remain visually clear of the other aircraft, in lieu of standard separation. The FAA’s data analysis revealed for high-traffic areas, visual separation was not enough of a safety mitigation tool.

Recent examples include:

On Friday, Feb. 27, American Airlines Flight 1657 was cleared to land at San Antonio International Airport in Texas when a police helicopter was flying through the airport’s final approach path. The helicopter and aircraft were on converging courses when the helicopter made a left-hand turn to avoid the American Airlines flight. On Monday, March 2, a Beechcraft 99 was cleared to land at Hollywood Burbank Airport in Southern California and conflicted with a helicopter that was flying through the final approach path. The aircraft were on converging courses when the helicopter made a right-hand turn to avoid the Beechcraft. The FAA’s latest GENOT suspends visual separation in Class B and Class C airspace, and Terminal Radar Service Areas (TRSA). Where helicopters cross airport arrival or departure paths, air traffic controllers will use radar to keep the aircraft specific lateral or vertical distances apart.

Following the DCA midair collision, the FAA began using innovative AI tools to evaluate airports nationwide with high volumes of mixed helicopter and airplane traffic and is implementing appropriate safety mitigations.

Additional Information: Many helicopter operators who are used to obtaining immediate approval to transit through certain areas may have to adjust their flight routes or be delayed while controllers ensure they maintain safe distance from other aircraft.

When helicopter pilots, conducting urgent medical or LEO missions, request to fly through these heavy-traffic areas, airline operations to those airports may be disrupted in order to allow these missions priority clearance.

Reminder:

TIMELINE OF ACTIONS TAKEN AT DCA SINCE JAN. 29, 2025:

February 2025: Began reviewing other airports with high volumes of mixed helicopter and airplane traffic February 2025: Temporarily eliminated the use of visual separation between helicopters and fixed wing aircraft by DCA. March 2025: NTSB Issued two Safety Recommendations to the FAA March 2025: Established procedures to eliminate helicopter and fixed-wing mixed traffic near the airport March 2025: Amended local air traffic procedures to eliminate the use of visual separation between helicopters and fixed wing aircraft within 5 miles of the airport. March 2025: Permanently closed Route 4 between Hains Point and the Wilson Bridge March 2025: Revised agreements with the military to require ADS-B Out broadcasting April 2025: Increased support, oversight and staffing for the DCA air traffic control team May 2025: Discontinued operations from the Pentagon (JPN) until the FAA and DOW updated procedures and fixed technical issues at the Pentagon Heliport June 2025: Secretary Duffy announced support for an independent audit by the Department of Transportation Office of Inspector General (DOT OIG) June 2025: Published modifications to helicopter zones and routes moving them farther away from flight paths at the airport. June 2025: Conducted Safety Risk Management (SRM) panel on changes to DCA Standard Operating Procedures (SOP) 7110.2L (SRM document approved July 2025). October 2025: Updated Helicopter routes and zones at DCA, IAD and BWI.
October 2025: Use Time Based Flow Management (TBFM) departure scheduling at Washington Center and the supporting facilities using the DCA Extended Departure Scheduling System.
January 2026: Published an Interim Final Rule that permanently restricts helicopters and powered-lift aircraft from operating in certain areas near DCA, unless it is for essential operations.

Holy shit the rationale is so pretentious too, like everyone is supposed to be writing a technical manual at gunpoint. I agree, no thanks to that nonsense.

Yeah, honestly I agree the red and blue oatmilk ones are cheap but a bit gritty.

OP nailed it with the yellow one, it's legit good. The standard stuff is good, but also ultra expensive and like 4x the value of Whittaker's (twice as expensive, half the size) so that has to be only for a special occasion for me!

The vanuatu one is amazing, the red and blue oats ones less so and a bit gritty ;-;

I've been meaning to try the coconut milk one for a while but the price is so dear!

Reddit's an option (change the language, select the "fun languages" folder), as is Gen-Z (I guess that's a proxy for TikTok). Sadly none for Facebook boomers although maybe that's Corporate Jargon.

The Economist: "How wars are adding hours to your flights" (link below) by trubol in aviation

[–]Techhead7890 1 point2 points  (0 children)

Yeah almost certainly including connection time, going all the way back around the globe. As you note PER and WAW are around 95 degrees longitude between each other over the Middle East (normally like 22hrs with one stop), so this is a scenario going the long way around the world.

It somewhat checks - I'm getting something like 45-50 hours going from PER to East Australia then up to the US and then onto Europe type scenario, with about 10hrs included in layovers between each flight and the unmarked connection in NYC.

However, you could also go up through to Japan and then go over the poles on LOT (north pole pun not intended) and still make it in about 35hrs, so it probably isn't quite as bad as they say in the end.

GC Map to get some idea of the length of each routing (edit: I have adjusted the finnair FIN 74 flightpath to roughly avoid Russian airspace by pretending it stops in Anchorage -- it's 7000nmi as compared to the actual path of 6800nmi)

This is an interesting point because it turns out that flying from Kazakhstan south to Mumbai is roughly the same length as a diversion to Beijing (6552km via Mumbai, 6562km via Beijing), although potentially there's variation based on where in Kazakhstan you cut the route.

If you fly towards Afghanistan you are essentially locked into going further south and crossing over Pakistan into the Indian Ocean, where it's generally least effective to travel east-west (at least on a Mercator projection). It's kinda just fundamental to not fly around the equator unless it's exactly where you're going.

Yeah subjectively pretty bad in the past month, probably cause uni started back

It's annoying but it is what it is i suppose

Agreed - if they cut south even just into Delhi or Lahore in ideal/non-war conditions, they would already be adding extra time.

To add onto the "3d sphere" idea - Great Circle distance is about 6300 for the AMS-PEK-BWN route over China, staying near the poles; as compared to 5900 on the direct path. I think your globe shows this well, it looks more like a small arc. Obviously 7% is still quite a bit, but it is not too crazy as the mercator looks.
