In 2026, with how much money their is in aviation, it seems wild to not have digitized this ages ago. The runway should be essentially 'locked' when in use, if they don't want screens in every ground vehicle that may cross a runway, at least display it at runway entrances.

That ATC still takes place over radio just seems insane at this point. And there's pretty much no way to make ATC's job not stressful, its inherently stressful. Taking out how much of their job is held in the current operators mind versus being 'committed' seems like low hanging fruit 30 years ago.

The whole system's just begging for human error to occur. There's 1700+ runway incursions a year in the US alone, each one should be investigated as if an accident occurred and fixes proposed. Like when an accident occurs.

matthewkayin an hour ago | parent | next [-]

While modernizing ATC in the US may be overdue, the real issue here is that ATC in the US has been understaffed, underpaid, and overworked for a while now.

My father works ATC and his schedule has him working overtime, 6 shifts a week, including overnight shifts, meaning that there is literally not a day of the week where he doesn't spend at least some time in the tower.

If that's the reality for even half of the controllers, it's no surprise that we've been seeing more and more traffic accidents lately.

No that is not the issue. Runway incursions have always been a problem and many deaths have occurred.

There have been many attempts to change phraseology, teach pilots and controllers to always readback runways, etc. but nothing that actually prevents the issue from occurring entirely via automation.

Imagine it were 90% automated. Now imagine there's a 3 hour outage of the automated system.

You're left with a bunch of planes in the sky that can't stay there forever, and not enough humans on the ground to manually land them.

Now image the outage is also happening at all airports nearby, preventing planes from diverting.

How do you get the planes out of the sky? Not enough humans to do it manually.

Now imagine the system comes back online. Does it know how to handle a crisis scenario where you have dozens of planes overhead, each about to run out of fuel? Hopefully someone thought of that edge case.

There's exceptions all the time. They turn back because a warning light came on. They saw a deer on the runway, a passenger got up to the bathroom. There's no way that could be automatic, plus they often need atc to look at their jet to see if it's damaged.

My suggestion is to restrict the use of smaller jets like crj and turboprops. I know airports like LaGuardia can't handle the big jets either, but they could reduce the slots and require a jet that holds, say, 150 people or more. This would result in fewer flights per day to some airports, but reduce overall congestion while still serving the same number of passengers.

dpark 2 hours ago | parent | prev | next [-]

Air traffic (and ground traffic) control are not simple problems. La Guardia has 350k aircraft operations (takeoffs and landings) every year. 1000/day. Peak traffic is almost certainly more than 1 plane every minute. Runways are always in use and the idea that some simple software will solve all the safety problems is not grounded in reality.

I’m not saying we couldn’t move more into automation. What I’m saying is that doing so will not solve all of our air/ground control problems. We still have human pilots and humans driving vehicles on the ground. Switching from humans directing landings to machines might improve some things but will not solve for all (and probably not most) risks.

Literally the crash here was caused by a fire truck entering the runway.

The ATC told them to enter the runway because they were confused or distracted due t overwork.

No one here or anywhere is saying automation would solve or be able to handle everything that human operators handle, that's an argument you invented that no one is making.

People are saying automation could handle a significant portion of the routine things allowing humans to handle the more complex/finicky issues.

Even if automation could handle 10% of the most common situations it would be a huge boon. In reality its probably closer to 50%.

cogman10 12 minutes ago | parent | next [-]

There's unfortunately an alertness problem WRT automated systems.

If the reason you have the human there is to handle the unusual cases, you run the real risk that they just aren't paying attention at critical moments when they need to pay attention.

It's pretty similar to the problem with L3 autonomous driving.

Probably the sweet spot is automation which makes clear the current set of instructions on the airport which also red flags when a dangerous scenario is created. I believe that already exists, but it's software that was last written in 1995 or so.

Regardless, before any sort of new automation could be deployed, we need slack for the ATC to be able to adopt a new system. That's the biggest pressing problem. We could create the perfect software for ATC, but if the current air traffic controllers are all working overtime and doing a job designed for 3 people rather than one, they simply won't have the time to explore and understand that new system. It'll get in the way rather than solve a problem. More money is part of the solution here, but we also need a revamped ATC training program which can help to fill the current hole.

I’m asking if it would have solved even the current situation. The truck presumably saw the red light, and was asking to cross. Would traffic control have said no if more had been automated and if so, what automation would fix this? Unless we are supposing the truck would be autonomously driven and refuse to proceed when planes are landing, in which case, maybe, though that’s not really ATC automation anymore.

It's worth pointing out that plenty of pilots take off and land safely at uncontrolled airports. ATC is a throughput optimization; the finite amount of airspace can have more aircraft movements if the movements are centrally coordinated. It feels like we are nearing the breaking point of this optimization, however, and it's probably worth looking for something better (or saying no to scheduling more flights).

The FAA already does issue temporary ground stops for IFR flights when ATC capacity is saturated. This acts as a limit on airlines scheduling more flights, although the feedback loops are long and not always effective. The FAA NextGen system should improve this somewhat.

A naive view that confuses the map with the territory.

While in a database state you write a row and reality updates atomically....for aircraft they exist in a physical world where your model lives with lag, noise, and lossy sensors, and that world keeps moving whether your software is watching or not. Failed database transactions roll back, a landing clearance issued against stale state does not. The hard problem in ATC is not coordination logic but physical objects with momentum, human agency, and failure modes that do not respect your consistency model.

You can't just throw software at this. It's a complex system that involves way more than just an airplane and someone in a tower. Systems engineering, human factors, and safety management systems are the relevant disciplines if you'd like to start reading up. In addition there are decades of research on the dynamics between human operators and automation, and the answer is never as simple as "just add more automation." Increased reliance on automation can paradoxically decrease safety.

CPDLC is already being deployed domestically. It's currently available to all operators in en route segments.

All runway incursions at towered airports are reported, classified according to risk, and investigated.

On the flipside, look at the success of TCAS. It doesn't have a perfect operational history. It hasn't completely eliminated midairs, either. But it took a relatively rare event and further reduced the frequency by about a factor of 5.

I wouldn't be so quick to rule out that there's some kind of relatively easy technological double check that could greatly reduce incidents. The fact that we've not gotten there despite years of effort to reduce runway incursions doesn't mean that it's not possible.

_moof 38 minutes ago | parent [-]

TCAS is fantastic - absolutely stellar example of effective automation.

But calling a replacement of major ATC functions with software a "simple fix" is a perfect illustration of why this is a bad idea. Nothing about human-rated safety-critical software is simple, and coming at it with the attitude that it is? In my view, as an experienced pilot, flight instructor, spacecraft operator, and software engineer, that thinking is utterly disqualifying.

Besides, there already are a lot of "simple" fixes in place for this problem, e.g. RWSL, which didn't prevent this accident.

It does, the Runway Status Lights System uses radar to identify when the runway is in use and shows a solid bright red bar at every entrance to the runway. I'm curious what the NTSB has to say about it for this incident. From the charts LGA does have RWSLs. I didn't check NOTAM to see if they were out of service though.

Airport emergency services are presumably trained in this, but since a plane cannot stop easily (or not at all on takeoff after V1), I seem to remember the general rule is that even emergency vehicles with lights and sirens on give way to planes, and don't enter runways without permission from the tower.

In the audio released by the BBC, the fire truck DID get permission from the tower to cross something, I can't tell if it was the runway in question. However, to cross the red runway lights if lit, you normally need that spelled out too something like "truck one, cross four delta, cross red lights". This did not happen on the BBC audio, which could mean one of many things.

The system is only advisory at present, so if the truck did see a warning light and proceeded anyway, they were technically permitted to do so.

The problem with the analogy is that aviation has no equivalent to "maintain a safe following distance" or "pull over and come to a stop". If a plane is on an active runway, or in flight, it's generally compelled by physics to keep moving forward one way or another. An automated system that prevented the truck from entering the runway would have been great, but an automated system that falsely reported a truck on the runway might have caused a disaster by forcing the plane into dangerous maneuvers to avoid it.

Traffic lights instead of mad max intersections are better.

Then there's subway Automatic Train Control.

I don't know that Air Traffic Control staff don't have computer systems for establishing which plane owns what airspace. They at least did do it manually already following specific processes, so it can be at least augmented and a computer can check for conflicts automatically (if it isn't already). And, sure, ATC could still use radio, but there could be a digital standard for ensuring everybody has access to all local airspace data. Or maybe that wouldn't help.

Your ground vehicle wanting to cross a runway could have the driver punch "cross runway 5" button (cross-referenced with GPS) and try to grab an immediate 30 second mutex on it. The computer can check that the runway is not allocated in that time (i.e. it could be allocated 2 minutes in the future, and that would be fine).

But, as pointed out elsewhere, obviously some of this is already present: stop lights are supposed to be present at this intersection.

The last time we "modernized" ATC was closer to the 90's than today, when there was still some general political will to make our government agencies modern instead of tearing them to pieces.

The FAA NextGen program has been running for literally decades. They have made some progress but there's a lot of work left to be done.

Ha. My first job in '89 was working for an FFRDC reviewing IBM's Jovial code that was going to "revolutionize ATC" by modernizing everything.

I'm gonna guess that code never went into production. The problem seems easy until you start looking under the hood.

There are systems for it, just not really integrated into emergencies and ground vehicles. Mistakes also happen even if all info required to avoid is present

There is digital comms with ATC without voice:

* https://www.faa.gov/air_traffic/technology/DataComm

But in the highly dynamic environment of final approach, landing, and taxiing, I doubt it would be practical. Unless we want to try autonomous 'driving' on taxiways and runways?

> There's 1700+ runway incursions a year in the US alone, each one should be investigated as if an accident occurred and fixes proposed. Like when an accident occurs.

How many runways crossings are there in a year? How much is "1700+" a percentage of that total?

snitty an hour ago | parent | next [-]

A "runway incursion" is a very broad term that includes everything from this accident to a single engine Cessna moving past the hold short line prematurely at a quiet airport.

FAA defines it as "Any occurrence at an aerodrome involving the incorrect presence of an aircraft, vehicle or person on the protected area of a surface designated for the landing and take off of aircraft." [0]

Many runway incursions run no risk of any accident, but are still flagged as issues, investigated, and punished if appropriate.

The point is that it doesn't matter what percentage of the total they are, it's that 1 is too high without adequate explanation (the Gimli Glider caused vehicles to be guilty of a runway incursion by turning an abandoned runway into an active one, for example).

And the cost of investigating 1,700 should be within the budget.

criddell 2 hours ago | parent [-]

Of course it matters. All of these entities have limited budgets and personnel and almost unlimited ways they could apply those resources. They have to choose what to chase and they do that by deciding how big of a problem it is.

bombcar an hour ago | parent | next [-]

If 1,700 is a huge percentage of runway uses (obviously it isn't but grant it, say at a single airport), then it's mandatory it be investigated because it's so huge.

If 1,700 is a minuscule fraction of all runway uses (as it likely is) then investigating it should be a proportionally minuscule amount of the budget.

There are five categories of incursion, with the top one being where a collision occurs:

* https://en.wikipedia.org/wiki/Runway_incursion#Definition

* https://www.faa.gov/airports/runway_safety/resources/runway_...

All incursions (in the US) are tracked:

* https://www.faa.gov/airports/runway_safety/statistics

Given there are ~45,000 flights per days in the US (and so aircraft and vehicles would move hither and fro around an airport for each flight), 1700 feels like a small number.

bombcar an hour ago | parent [-]

Exactly - it's a small number and should be investigated, because if we reduce the number of all incursions, we reduce the number of collisions (and fatalities).

throw0101d 29 minutes ago | parent [-]

They are classified as operation/ATC error, pilot error, and vehicle/pedestrian error.

Human can misspeak or mishear instructions, but if they were communicated and understood correctly (a read back was correct), but the pilot had a 'brain fart' and went forward instead of stopping, how do we eliminate brain farts?

bombcar 12 minutes ago | parent [-]

That's a big part of the story of aviation; the way things are communicated has changed because of brain farts, the way things are lined up, etc.

See 5-2-5 for an example:

https://www.faa.gov/air_traffic/publications/atpubs/aim_html...

NOTE- Previous reviews of air traffic events, involving LUAW instructions, revealed that a significant number of pilots read back LUAW instructions correctly and departed without a takeoff clearance. LUAW instructions are not to be confused with a departure clearance; the outcome could be catastrophic, especially during intersecting runway operations.

The older term was "hold short runway X" and that was too close to "hold runway X" - the first meant do NOT enter the runway, the second meant enter and line up but do NOT takeoff.

You can't know how big of a problem it is without an investigation. Frequently, the initial "obvious" cause of a collision or incursion turns out to be a multi-layered set of failures. Tightening up procedures or recognizing a previously overlooked defect in the systems makes us all safer and should be prioritized.

We talk about Vision Zero for streets. Vision Zero is actually achievable in aviation.

You seem to be giving too much credit to the singleton design pattern. We know exactly how well that works on a modern, multi-tasking, preemptible operating system (hint: not well at all).

> That ATC still takes place over radio just seems insane at this point.

Voice communication is insane? I suspect you are ignorant of what it is like to actually fly a large aircraft into a busy airport. Fault-tolerant and highly available hardware must facilitate low-latency, single-threaded communication with high semantic density in order to achieve multi-dimensional consensus in a safety-critical, heterogeneous, adversarial environment.

There is some interesting research that captures this sentiment and shows how complex a solution might need to be (replace "faulty agent" with "human error"): https://www.sciencedirect.com/science/article/abs/pii/S00051...

lxgr 2 hours ago | parent | next [-]

Listening to some recent close call ATC tapes, yes, it seems absolutely insane to manage current traffic levels with the existing number of controllers over voice.

I don't doubt that it's a very safe system with enough slack allowing for intentional redundancy. But as it is, some of these controllers seem to be limited by their ability to pronounce instructions, leaving absolutely no margin for error and presumably very little room for conscious thought.

ianburrell 2 hours ago | parent | prev | next [-]

Voice communication has the advantage is that it can be used without taking off hands and attention off controls. Digital solution would require using device.

lxgr an hour ago | parent [-]

Voice communication can still be used for anything out of the ordinary despite automating the common case.

Almost all voice transmissions are routine instructions/clearances from ground to air, with the pilots reading them back to reduce the chance of errors. In fact, this already exists and is in wide use in (at least) the US, EU, and in transoceanic airspace.

Of course, now you have two systems that can fail, and reducing reliance on the older one can easily cause automation complacency (which is a well-researched source of errors) and require more frequent refresher courses if the skill is not practiced on a continuos basis.

I suspect that that these are the reasons it's not commonly used for approach and tower operations: There's a lot more spontaneous and/or nonstandard stuff happening in those flight phases, and as you say you don't want a pilot's eyes on a tiny screen/keyboard instead of on their instruments or out the window.
