I am not sure the subsequent line of discussion over how Class B requires ATC (not pilots) to separate all traffic is a very productive one. Any separation instruction given by ATC relies upon the pilot executing it, for instance by maintaining the cleared altitude. Here, it relied on the pilot not colliding with the specific traffic he had confirmed visual contact with. So far as the FAA is concerned, that's a sufficient degree of control and differs from the "see and avoid" principle applicable to VFR/VFR in Class C, and VFR/Any in Class D. Again, the question is whether that's appropriate. . Listening to the NTSB , the only ATC instruction given : to " pass behind " was not received , and therefore not acknowledged by the crew , so we are here 100% in the good old "see and avoid" scenario I would say Subjects

WMF,
… well having searched the usual places and the NTSB, you will have to help with directions and text for reference. There is a NTSB Charter for data, but nothing which explains the link between ICAO and the USA, and thence to the NTSB and investigation, or the required statement of any USA deviation from the ICAO guidance (Annex 13). Notwithstanding https://www.ntsb.gov/about/organizat...office_as.aspx " fulfill U.S. obligations under International Civil Aviation Organization agreements" "to examine specific aviation safety problems from a broader perspective. " But back to the thread. Are there any reasons why NTSB might not comment on the wider organisational aspects as indicated in the discussion. Also noting that the NTSB have no powers of enforcement, relying on the FAA; thus if the FAA process were to be identified as deficient, who mandates change. ,, Subjects

I cannot cite anything specific to support it but I'm strongly inclined to think Chair Homendy, at this point in her public service career, will insist on a report and supporting analysis that leaves, if you will, political niceties on the bottom of the Potomac shy of the Rny 3-3 threshold -- where they belong.

At what distance and light conditions should any average (heli) pilot be able to identify specifically a \x93CRJ\x94 ? That stand alone, or after having been told what other traffic was in range and view. For example another being a biz jet or A320. And this question for both daytime and at night. Would that performance improve when ATC would supply them with say \x93at your 11 o\x92clock and 1,500 ft and 150 kt and intent (visual to rwy33)? And would that performance improve at say 3 o\x92clock? Amazed that visual separation responsibility ended up in the lap of the \x91least able\x92 party involved that some here describe as being \x91clinically\x92 blind ! On the NTSB - as far as I have understood it, they can study and recommend on anything. They could for example start an SS parallel to this investigation addressing this wider issue. Subjects

Assuming they correctly received/understood that the object they were to pass behind was landing runway
33
, not runway 1. That seems to be in some doubt.
Because without that information, they could IMHO quite happily look at the A319 approaching runway 1, intend to pass behind it to head south down-river until the A319 was no longer over the river, and loiter around the runway 33 approach until that happens. (Not sure why this little hamster wheel is still spinning, but this is PPRuNe). Subjects

[safetypee's emojis and comments ommitted] Almost invariably lawyers as well as law students and professors, when asked to comment about what is taught in law school, recite the truism that "law school teaches you how to think like a lawyer." Problem is, even quite modest experience in and with the realities and pressures of representing clients - i.e., practicing law - dulls the thinking part and intensifies the hustler mentalities, of which there are many variations. I'm noting this because law school actually trains you how to spot the issues. It sometimes is the case that the standard things lawyers think about a given set of issues are not the most relevant and meaningful things. With that hopefully not grossly pedantic context out of the way..... in previous comments on this thread I've noted that the federal defendants would be expected to assert sovereign immunity.... more technically, that although the Federal Tort Claims Act waives sovereign immunity in general terms, the statute also contains various exceptions - in other words, the exceptions where they apply keep sovereign immunity in place. The exception relevant here is the "discretionary function" exception, which (pardon the attempt at over-simplifying it) keeps the immunity in place if the allegedly negligent act (or omission) resulted from a federal entity's policy decision or choice. I previously viewed the discretionary function exception is likely imposing a pretty strong barrier against liability of the (probable) federal defendants. However. However. However, as I write this somewhere in an aviation law practice a mid-level or even junior associate is pounding their computer keyboard, amassing BASED ON THE ISSUES NOW REVEALED an analysis of how the discretionary function exception has never, never ever ever, been imposed to bar liability for alleged negligence roughly and/or reasonably comparable to the record of "encounters" now documented by NTSB Prelim Report. And that record goes back several years . . . but presumably discovery in United States District Court under the Federal Rules of Civil Procedure could easily reach back to even more past years. Of course, it will be said that ignoring these many encounters was indeed a policy choice, and so the exception does apply, a forum post like this notwithstanding. But that's just the point. The ISSUE here is that there never was a conscious policy directive which the alleged negligence stemmed from. Or stated another way, if I were in the aviation practice imagined above, I'd be running associates ragged to amass the above-mentioned analysis which establishes, among other things, that GROSS NEGLIGENCE by the FAA can never be, and is not as a matter of law, a predicate for applying the discretionary function exception. (For lawyers out there, somewhat akin to prima facie tort.) By the way, for all the discovery sports fans out there, just think how much fun it will be to run discovery to amass the facts of what actions - meaning by the aircraft in which the RAs were annunciated - were taken as a result of all the RAs as noted by NTSB's Prelim Report.

One example, after the KBED G IV accident, the NTSB went to the NBAA asking for help in better use of FOQA data increase compliance with flight control checks. Remember, this the G IV crew who tried to take-off with locked controls. ASIAS has tens of thousands of flight control checks and compliance data. Focused on that, measure it, problem mostly solved. GE Digital’s FOQA programs also have a tremendous data bank. For example, KTEB has an easily the highest rate of TCAS encounters for corporate operators. How it compares to KDCA, I again cannot say. The airlines have the KDCA data for their operations. They know how many and where TCAS events occur. More evidence of normalization, I suppose. Subjects

The catastrophe publicised the problem of trains travelling too close together, with signalmen having to appraise the situation too quickly for safety's sake. A simple communication mistake between the two signal boxes caused havoc that Sunday, but the telegraph was also blamed for the tragedy because it did not register without continual pressure on the switch. The signal, too, was also at fault for not returning to "danger" immediately after the train had passed. The accident encouraged the use of the
block system
(rather than the
time interval system
) for the remainder of the railway system.
One other aspect of this accident was that Signalman Killick was working a continuous 24-hour shift that day, rather than the regulation 18 hours to gain a complete day off duty. In his report on the accident Captain Tyler stated that "it was disgraceful that a man in so responsible a position as Signalman Killick should be compelled to work for twenty-four hours at a stretch in order to earn one day of rest a week."

"That's good thinking there, Hot 'n' High." (with apologies to the late Tom Wolfe for my copying the opening line of his 1968 New Journalism book, The Electric Kool-Aid Acid Test)
1) The starting point for any of my thought process about the midair collision is that this accident should never have happened and would not have happened without some parts of "the system" failing to fulfill their assigned responsibilities. Midair collisions in U.S. airspace are an aberation, aren't they? I sense that many aviators and other aviation professionals don't want to say it out loud - their sense of disbelief that this actually occurred. A few years ago, in response to a question after a guest lecture he had delivered at an ICAO event in Montreal, then-Chair of the NTSB Robert Zumwalt said, "we've already had that accident" . . . the question was about whether an accident caused by certain factors which were, in fact, present in the Colgan Air accident needed to happen, in order for certain rules to be changed. (I don't want to misstate the q&a, although my best recollection was that the question was about fatigue and rest, and commuting time before line service.) In other words, the DCA midair is not an accident the primary causes of which were factors the overall aviation system had not quite learned to do correctly. In comparison, at the time I first began "reading aviation", wind shear accidents were occuring not infrequently (that beginning was December 1974). I have not represented anyone or anything in air crash litigation and my posting here is not intended as what most lawyers call "client development and prospecting." Despite that, I think the opening statement on behalf of the families of the victims of this accident will be quite a courtroom moment. It's against this backdrop that I've been trying to think through the federal entities' most likely defense. There is some sense, maybe only vague, that how the anticipated lawsuits play out will have some impact or bearing on how the overall aviation system responds to this tragic occurrence. 2) Not for the first time my choice of phrasing was too emphatic and also imprecise. I didn't mean to point to ASIAS as a foundational or ultimate component of decisions about safety of DCA airspace management and usage. Instead, the content of some of the incident reports pointed out by Juan Browne struck me as glaring. They struck me as strong evidence of two things; one - as noted above, this accident was the kind of occurrence caused by some part of the system not fulfilling its responsibilities, and the other, that there were pretty clear statements by "bottom-up" reporters about such responsibilities appearing to be unfulfilled at particular times and in particular situations. So, from these two foundations, I'm trying to figure out whether the discretionary function exception applies or does not apply. If it applies, the federal court will not have jurisdiction over the claims and the federal defendants will enjoy immunity (irony intended). I apologize in advance for what follows next (it is quoted in full from Congressional Research Service Report (R45732.8, April 17, 2023) "The Federal Tort Claims Act (FTCA): A Legal Overview". I would not clutter up this respected forum with legal material were it not arguably necessary for meaningful discussion of what is likely to happen next in the aftermath of the night of January 29. CRS: "[T]to determine whether the discretionary function exception bars a particular plaintiff's suit under the FTCA, courts examine whether the federal employee was engaged in conduct that was (1) discretionary and (2) policy-driven. "If the challenged conduct is both discretionary and policy-driven," then the FTCA does not waive the government's sovereign immunity with respect to that conduct, and the plaintiff's FTCA claim must therefore fail. If, by contrast, an official's action either (1) "does not involve any discretion" or (2) "involves discretion," but "does not involve the kind of discretion\x97consideration of public policy\x97that the exception was designed to protect," then the discretionary function exception does not bar the plaintiff's claim. Whether the Challenged Conduct Is Discretionary When first evaluating whether "the conduct that is alleged to have caused the harm" to the plaintiff "can fairly be described as discretionary," a court must assess "whether the conduct at issue involves 'an element of judgment or choice' by the employee." "The conduct of federal employees is generally held to be discretionary unless 'a federal statute, regulation, or policy specifically prescribes a course of action for an employee to follow.'" If "the employee has no rightful option but to adhere to the directive" established by a federal statute, regulation, or policy, "then there is no discretion in the conduct for the discretionary function exception to protect." Put another way, the discretionary function exception does not insulate the United States from liability when its employees "act in violation of a statute or policy that specifically directs them to act otherwise." Even where a federal statute, regulation, or policy pertaining to the challenged action exists, the action may nonetheless qualify as discretionary if the law in question "predominately uses permissive rather than mandatory language." In other words, where "a government agent's performance of an obligation requires that agent to make judgment calls, the discretionary function exception" may bar the plaintiff's claim under the FTCA. Notably, "[t]he presence of a few, isolated provisions cast in mandatory language" in a federal statute, regulation, or policy "does not transform an otherwise suggestive set of guidelines into binding" law that will defeat the discretionary function exception. "Even when some provisions of a policy are mandatory, governmental action remains discretionary if all of the challenged decisions involved 'an element of judgment or choice'". [End CRS, all quotations in the excerpt as in original, and all footnotes omitted] 3) Which leads to this essential inquiry: which one - and the answer cannot be "both are involved" - is closer to what happened: the federal entity individuals involved at all levels acted in violation of a statute or policy that specifically directs them to act otherwise", or, the federal entity individuals' "performance of an obligation require[d] that agent to make judgment calls", and "all of the challenged decisions involved an 'element of judgment or choice.'" On one hand, the imperative of separation of aircraft in controlled airspace is pretty absolute, as far as I have been given to understand. There isn't any discretion or choice to risk a collision at an "intolerable" level of likelihood in order to keep traffic moving, both airline and the military and other helicopter operations in question. And that was the query I was attempted to point out: the midair collision at DCA on Janaury 29 looks like the proverbial death of a thousand small cuts, such that there never was any "judgment" or "choice" as those (admittedly ambigous) terms are employed in the statute and its interpretation. I should have been clearer about only imagining that one of many hypothetical situations where - arguing for the defense - someone was looking at ASIAS and proceeded with the calculating or reasoning which presumably would qualify as "judgment" or "choice." The larger point is that taking account of all the safety information in all the system elements which have been noted and others which might not have been noted here, mark me down as quite skeptical that there ever occurred a time, at a particular place, where anyone acting on behalf of the federal government exercised judgment or discretion that - contrary to the assessment of the NTSB Chair - the risk at DCA was tolerable. Two caveats to wrap: I don't envy the advocates for the victims' families, as it will be terribly challenging to argue the facts of this case without appearing to cast aspersions on some or all of the pilots and controllers. Nobody wants that, and I certainly don't. The other is that I do not think that the discretionary function issue will play out in the context of the actions by the pilots of either aircraft or the controllers. Rather it will be litigated with regard to the way FAA (and its parent Cabinet department, DoT) structured, managed, and operated DCA airspace. And this could include staffing policies and procedures (but again, not individuals' actions or inactions on the night of the accident). There may be some involvemenmt of civil-military coordination also at the agency level. On a somewhat personal note, just a few years ago I traveled by air to a major European capital where a quite substantial and important aviation industry organization has its headquarters; the purpose was to attend a conference hosted by that organization. When the flight ended, because I had not previously traveled on a 787 aircraft, I asked the cabin crew if I could please get an invitation to visit the flight deck to see it, if doing so would not unduly delay the pilots from deplaning. When I got admitted to the flight deck, the captain invited me to sit in the LHS, and then gave me his hat and offered to take my photograph (yes, really). In the snapshots this SLF/attorney looks pretty ridiculous, and I wonder, "what am I, ten years old?" I hope neither this post nor any others look like they were written by that kid. Subjects

Of course in this case the thing known to degrade safety is "see and avoid", the regulator is the FAA, and the relevant parts of the user community appear to be "near as damn all of it". Focusing on the Army pilots' failure to achieve it would be a neat distraction from the much more difficult question (for everyone) of whether it is an appropriately safe means of separating from airline traffic. The nice NTSB diagram of Route 4 and the 75 feet spacing dodges the issue that neither the controller nor the Army pilots assumed that procedural separation existed; visual separation was being applied. The permanent closure of Route 4 could be seen as acceptance that this was an unsafe basis on which to permit operations. However it still misses the point. The route was capable of being operated safely, for instance by holding helicopter traffic or avoiding use of runway 33 when needed to prevent conflictions, but that would have been tacitly to accept that visual separation was unsafe. Closing the route also only fixes the issue on one runway at one airport. Where next? Last edited by Easy Street; 22nd March 2025 at 13:08 . Subjects

The vast majority of flights I was on (even when I was not an instructor) were correctly classified as training missions (the post maintenance check flights were not, and the combat missions were not). (I was a Navy pilot for 25 years. The Army follows a similar documentation scheme). The word "Training" is utterly irrelevant. This has been explained multiple times in this very thread.

What I was suggesting was that being on a NVG training exercise required (or very strongly recommended) the pilot to use NVGs regardless of their impact on the pilot's performance at the task in hand. I totally agree with your last two sentences. Last edited by Peter H; 24th March 2025 at 20:03 . Subjects

T....... Nevertheless if you are driving a truck and you don't plan your route properly, you ignore the signs saying no trucks on the expressway, you ignore the signs saying low clearance ahead you disregard the fact that you are about to try to drive under an overpass which is lower than your truck is high and you plow into it at sixty miles an hour then you were negligent. .........
Agreed 100%! After all, many air accidents are because pilots are in the wrong place - a good example is the current sister Thread to this one covering a plane which started to take-off from a taxiway - sadly a regular occurrence. Lots of people are asking "How on earth......." - but they did, just as others have done before them! I'll not comment further as the discussion is on that Thread anyway which you can read and the Investigation is early days so far. However, one of the reasons aviation is so safe today is because the aviation community realised a big driver to improving safety, based on the premise that humans are both ingenious in devising new ways to screw things up - as well as being quite capable of repeating the old ways too - was to understand if additional issues were contributing to those accidents. In particular, anonymous self-reporting of "near misses" provides much valuable information enhancing the understanding of issues before anyone dies. There were many "near miss" reports relating to this route/runway as has been mentioned. But no-one joined the dots........ By understanding how those additional factors contributed to the near miss/accident means further mitigation could be put in place. Maybe one of the most significant - Flight Time limitations - have come about as, after a number of accidents, people realised just how a lack of proper rest significantly degrades human performance and so contributed to poor decision-making, particularly when under pressure. I just use that as an example of "contributory factors" - possibly not relevant here - the full Report is not out yet. In this case, the helo crew ended up flying into a jet. But why did they do that? Well, when the NTSB recommended that Route 4 be closed, it described it as being "an intolerable risk to aviation safety by increasing the chance of a midair collision.". If the helo crew mistook another aircraft to one they should have been avoiding (a likely mistake) there was little effective mitigation to prevent that mistake leading to catastrophe - hence the recommendation from the NTSB. What there was in terms of mitigation - such as the ATCO - failed. The ATCO suddenly realised all was not quite right but he didn't have the time to come up with a solution to save the day and a collision happened on "his watch". I can't even imagine what he is going through right now every single day..... Yes, by all means decide liability for recompense to those who lost loved ones on that fateful day - (top tip, go where the money is!). The legal people like our esteemed fellow PPRuNer, WillowRun 6-3 , will do that. What the aviation community itself wants to ensure is that such a mistake (which will happen again - as I said, whilst humans are extremely inventive in finding out new ways to screw up they are also prone to be quite capable of repeating mistakes ad infinitum) - never leads to such deaths in the future. That's why people look, in great depth, behind the obvious cause for the crash to see what more can be done. That's why it's so safe for you to step aboard an aircraft today. To reiterate, in the words of the NTSB, the aviation world was running a route which provided "an intolerable risk to aviation safety by increasing the chance of a midair collision.". So, one question, who approved that ..... and where is the Safety Case to support that decision? Cue tumbleweed rolling slowly down the road...................... I hope this helps explain why it's wayyyyyy more than "The crew screwed up. End of story!". Cheers, H 'n' H Subjects
