Re: WASHINGTON D.C. | Commercial Jet vs Military Helicopter Over Potomac
Some air traffic control scanner before the incident.

Re: WASHINGTON D.C. | Commercial Jet vs Military Helicopter Over Potomac
That URL shows the current flight of the airframe, and has now moved on from the accident flight to the next scheduled flight (which, unsurprisingly, has been cancelled). Pls replace with this URL which refers specifically to the accident flight: https://www.flightaware.com/live/fli...328Z/KICT/KDCA |

Re: WASHINGTON D.C. | Commercial Jet vs Military Helicopter Over Potomac
According to ADS-B data the helicopter was not travelling particularly quickly. (*) The helicopter did not travel behind the commercial jet. It was supposed to, and if it did there would not have been an accident. Why do you say that? (*) We need to be careful when interpreting the flight path of the military helicopter on flight tracking sites because it was not transmitting a GPS position (as most other flights do). The position of the helicopter was estimated based on differential time of arrival of the ADS-B signals (this is called MLAT), which is not especially accurate and why the flight path looks so jagged on tracking sites. |

Re: WASHINGTON D.C. | Commercial Jet vs Military Helicopter Over Potomac
Attached is a more comprehensive audio recording of the ATC traffic (source: blantonl on RadioReference): Also attached is the relevant part of the Washington DC area Helicopter Route Map (source: FAA/Skyvector) showing helo routes in the area. From this it is apparent that helicopter traffic routinely follows the path that PAT25 took. PAT25 was following ROUTE 1 southbound. The "Memorial" reporting point referred to in the ATC audio is the ble solid triangle marked "Memorial Bridge" on ROUTE 1 north of the Pentagon. |

Re: WASHINGTON D.C. | Commercial Jet vs Military Helicopter Over Potomac
So I live less than a mile from where this occurred and I am also a licensed pilot. First let me say that this airspace is amongst the most controlled in the US, if not the world. The CRJ was cleared for RW1 which is the most common approach into the longer of the runways at DCA. If you've ever flown into DCA it's an approach that basically follows the Potomac River. JB Bolling base is located to the SSE of DCA and helicopters are often given clearance to shoot across the river and instructed to maintain visuals on traffic. Due to the location of Bolling, almost all of the air traffic is either landing on RW1 or taking off of RW1 and it's relatively easy to maintain visuals on air traffic. Shortly before the crash, ATC asks the CRJ if they can switch to RW33 which is a shorter runway and runs from SE to NW. This change would have required the CRJ to do "right slip approach". Not a huge adjustment but something that only smaller jets could be able to do safely. That change placed the airliner a little further north than usual. Usually the helo traffic from Bolling is instructed to quickly cross the Potomac and the responsibility is largely theirs to keep an eye on the traffic to DCA (which is why they asked if they had a visual) The jet and the UH60 though are NOT on the same frequency and it's unlikely the UH60 was aware that the CRJ's runway (and approach) changed. My suspicion (it's still early into the investigation) is that we are going to find that several things came together at the wrong time but I doubt that any sort of "pilot error" is responsible. I had 2 friends ive known most of my life on the CRJ returning from KS and am still in shock that this happened. |

Re: WASHINGTON D.C. | Commercial Jet vs Military Helicopter Over Potomac
once the helicopter pilot was given Visual Flight Rules, it was his job and responsibility to create the separation. unfortunately he didnt create that and ultimately caused the crash.

Re: WASHINGTON D.C. | Commercial Jet vs Military Helicopter Over Potomac
he was told multiple times about the traffic which he acknowledged. I think he saw traffic behind the jet involved

Re: WASHINGTON D.C. | Commercial Jet vs Military Helicopter Over Potomac
literally any time two aircraft make contact with each other in the air, there was "pilot error" involved. |
