Can Claude Fly a Plane?

4/14/2026 at 12:26:18 PM

“Automation can lower the workload in some cases. But in other situations, using automation when it is not appropriate can increase one’s workload. A pilot has to know how to use a level of automation that is appropriate... Whether you’re flying by hand or using technology to help, you’re ultimately flying the airplane with your mind by developing and maintaining an accurate real-time mental model of your reality—the airplane, the environment, and the situation. The question is: How many different levels of technology do you want to place between your brain and the control surfaces?“[0]

I‘d say the same holds true for other use cases and should not only target vibe coders. Eg self driving cars. Level 2 is fine and level 5 is good, it‘s in between these two where I‘m afraid of as people are distracted enough and not able enough to gather what‘s happening around them to react in every situation.

We already have advanced autopilots that can fly commercial airliners. We just don't trust them enough to not have human pilots. I would trust the autopilot more than freaking Claude. We already do, every day.

I think we can trust them to not have human pilots. It is just that having human in loop is very useful in not that rare scenarios. Say airfield has too much wind or fog or another plane has crashed on all runways... Someone needs to make decision what to do next. Or when there is some system failure not thought about.

And well if they are there they might as well fly for practise.

And no. I would not allow LLM in to the loop of making any decision involving actual flying part.

by Ekaros

4/14/2026 at 7:37:11 AM

There's also the issue that when something goes wrong, many people will never trust an autopilot again. Just look at how people have reacted to a Waymo running over a cat in a scenario where most humans would have made the same error. There's now many people calling for self-driving cars to never be allowed on roads and citing that one incident.

> We just don't trust them enough to not have human pilots.

Much of the value of a human crew is as an implicit dogfooding warranty for the passengers. If it wasn't safe to fly, the pilots wouldn't risk it day after day.

To think of it, it'd be nice if they posted anonymized third-party psych evaluations of the cockpit crew on the wall by the restrooms. The cabin crew would probably appreciate that too.

by boring-human

4/14/2026 at 7:43:17 AM

There are soooo many pilot decisions that AI is nowhere near making. Managing a flight is more than flying. It is about making safety decisions during crisis, from deciding when to abort an approach to deciding when to eject a passenger. Sure, someone on the ground could make many of those decisions, but i prefer such things be decided by someone with literal skin in the game, not a beancounter or lawyer in an office

by sandworm101

4/14/2026 at 9:28:47 AM

I doesn't sound ethical to eject passengers while aborting an approach, regardless of precise timing.

> It is about making safety decisions during crisis, from deciding when to abort an approach to deciding when to eject a passenger.

Everyone likes to hand wring about this sort of stuff but I think it's the exception. Nailing the "macro level" decisions like "we'll go around this storm but we'll go over that one" or "we must divert to A or B and we will chose B because it's better for our passengers/company/crew even if it's 10min more flying to get there" are what keep the industry humming along mostly in the black rather than in the red. And it's these sorts of things that AI just tends to yolo and get mostly right when they're obvious but also get immensely wrong when any sort of gotcha materializes.

by cucumber3732842

4/14/2026 at 7:51:44 AM

I sincerely doubt that pilots decide "when to eject a passenger". Mostly it would be the cabin crew: the flight attendants are 100% in charge of flight safety, and they would be managing relationships with passengers, and they would be the ones to make the call. It would ultimately be them calling some kind of law enforcement. If an Air Marshal is onboard already, obviously they would be on the front line as well.

Furthermore, the concept of "ejecting a passenger" from a flight would mostly not be something you do while in the air, unless you're nuts. Ejecting a passenger is either done before takeoff, or your crew decides to divert the flight, or continue to the destination and have law enforcement waiting on the tarmac.

Naturally, pilots get involved when it's a question of where to fly the plane and when to divert, but ultimately the cabin crew is also involved in those decisions about problem passengers.

by ButlerianJihad

4/14/2026 at 8:21:04 AM

The Pilot in Command has ultimate legal responsibility over the operation of the flight, ICAO conventions explicitly state this. Whilst in practice the cabin crew will be the ones dealing with the passenger(s) and supplying information to the PIC , it won’t be them making the final decision.

by rounce

4/14/2026 at 8:32:41 AM

No. Cabin crew recommend. Pilots actually decide.

by sandworm101

4/14/2026 at 8:57:35 AM

Do the pilots also decide whether to issue a parachute to the ejected passenger?

by ButlerianJihad

4/14/2026 at 9:28:06 AM

Pretty sure ejection here is meant as shorthand for "Transfer the passenger to an entity on the ground to proceed from there" whether that entity is emergency medical services or law enforcement is secondary.

It would be interesting to see if Claude can land and take off. Don't think the autopilot can do that yet.

by zenmac

4/14/2026 at 10:26:56 AM

> Don't think the autopilot can do that yet.

It absolutely can; it's called autoland[1]. In really bad visibility, pilots simply can't see the runway until too late, and most aerodromes which expect these conditions have some sort of autoland system installed. The most advanced ones will control every aspect of the plane from top-of-descent (TOD), flaps and throttle configuration, long and short final, gear down, flare, reverse thrust, and roll-out, all the way to a full stop on the runway. Zero pilot input needed.

And most of this was already available in the late 1970s. We have absolutely no need for LLM-based AI in aviation; traditional automation techniques have proven extremely powerful given how restricted the human domain of aviation already is.

4/14/2026 at 8:54:06 AM

Autopilots can. Both on airliners and small planes, although only landing on the latter as far as I know and it's only meant for emergencies. Airbus ATTOL is probably the most interesting of these in that it's visual rather than ILS (note that no commercial airliners are using this).

Because humans are the fallback for all the scenarios that the tech cannot reliably cover. And my intuition says that the tech around planes is so heavily audited that only things that work with 99.999...% accuracy work will be left to tech.

by stnikolauswagne

4/14/2026 at 8:52:17 AM

Still those technological issues do happen, and in those situations it's good to have a human pilot in control. See for example Qantas Flight 72 - the autopilot thought aircraft was stalling, and sent the plane into a dive. It could have ended up very badly without human supervision.

by reeredfdfdf

4/14/2026 at 1:48:13 PM

That's so incredibly reductive, that I'd go ahead and call it plain wrong.

"Caused by a human" is the lowest tier, first base human instinct analysis of any accident, and as such, unless proven otherwise, can be discarded out of hand.

It comes down to: if a human mistake is capable of causing an accident, your system is badly designed because it assumes a part of the system known to be unreliable (a human) is always reliable.

The whole trick is designing systems that are safe despite humans being in the loop. Then you get to benefit from the advantages humans bring over machines without suffering the downsides.

The question of 'can it fly' is clearly a 'yes, given a little bit of effort'. Flying isn't hard, autopilots have been around a long time. It is recognizing and dealing with things you didn't anticipate that is hard. I think it is more interesting to have 99% of flying done with automated systems but have an LLM focus on recognizing unanticipated situations and recovering or mitigating them.

4/14/2026 at 7:29:13 AM

>I think it is more interesting to have 99% of flying done with automated systems but have an LLM focus on recognizing unanticipated situations and recovering or mitigating them.

Seeing how Claude (or any current LLM) perform in even the most low-stake coding scenario I dont think I would ever set foot on a plane where the 1% of most risky scenarios are decided by one.

by stnikolauswagne

4/14/2026 at 9:55:32 AM

General LLMs I would say are uniquely bad at this sort of thing.

I mean if you have a stable plane, then it'll do alright, as it'll mostly fly straight and level (assuming correct trim) reacting to turbulence however, the sampling rate would probably too slow, so you'd end up with oscillations.

For recognising that you're in a shit situation, yeah, it'll probably do that fine, but won't be able to give the correct control inputs at the right time.

by KaiserPro

4/14/2026 at 10:12:00 AM

>For recognising that you're in a shit situation, yeah, it'll probably do that fine, but won't be able to give the correct control inputs at the right time.

Even that im not sure of, I know relatively little about aviation safety but I can imagine that there are all kinds of 0.0000000001% percent corner cases that no plane has ever encountered that still need some sort of reaction, who knows how easy an llm can distinguish those from the 0.000000001% corner cases that no plane has ever encountered that are completely fine and can be ignored.

by stnikolauswagne

4/14/2026 at 10:35:04 AM

I agree with your intuition, There are lots of corner cases, but there are also a fucktonne of checklists: https://www.aviationhunt.com/boeing-737-normal-checklists/ (this is just a small "normal" one) but for loads of situations there are check lists, thats something the LLM can probably do very well.

However its as far as I know the check list volume scales with how "airline-y" the plane is. so for a one seater, the checklist is small and only handles a few things. For a 777 its a binder.

by KaiserPro

4/14/2026 at 7:56:02 AM

Using an LLM doesn't mean it has to take the final decision. You can also use it as a warning system.

by amelius

4/14/2026 at 1:53:34 PM

False negatives are a huge issue when designing safety systems. It is not the case that "more warnings = more better".

by Mawr

Is there any indication that current warning systems are insufficient in any way that would be improved by LLM involvement?

We won't know that until someone has actually investigated how an LLM would do in those scenarios.

by vidarh

That sounds like a solution looking for a problem though, i see plenty of arguments against throwing critical safety information that are in charge of peoples lives into an LLM "just in case the result is better than the result that the current battle-hardened systems already provide"

Can you give an example scenario?

by amelius

4/14/2026 at 11:04:56 AM

To properly test an LLM based emergency system against the current as-is system there needs to be a way of verifying whether the LLM detected emergency is classed as an emergency as-is. If this information was available publicaly it could enable bad actors things like stress-testing the EMP-tolerance of the current systems or what level of malware infiltration is detected.

The bit in the middle where it decides to make its control loop be pure P(roportional), presumably dropping the I and D parts, is interesting to me. Seems like a poor choice.

I try to fly about once a week, I’ve never really tried to self analyze what my inputs are for what I do. My hunch is that there’s quite a bit of I(ntegral) damping I do to avoid over correcting, but also quite a bit of D(erivative) adjustments I do, especially on approach, in order to “skate to the puck”. Density going to have to take it up with some flight buddies. OR maybe those with drone software control loop experience can weigh in?

"Actual controls engineers" use PD loops (no I) all the time.

by gbgarbeb

4/14/2026 at 7:55:14 AM

In some circumstances, yes (usually when the system itself acts as an integrator somehow). Aircraft controls do not strike me as a system where this is sensible (trimming an aircraft is basically an integral control process).

(d'oh, should have read the specific context: in the case mentioned, it is where the system acts as an integrator (pitch -> altitude), and so pure P control is pretty reasonable)

"Can I Get Claude to Fly A Plane" isn't the same thing. Interesting though, would be a good test for different models but it relies on the test harness being good enough that a human could also use the same info to achieve the required outcome. e.g. if latency of input/output is too slow then nobody could do it.

Claude uses the wrong modality to be a piloting model. Latency is critical, and outputting tokens in the hope they take the action at the right time is kinda bonkers.

You'd want all the data from the plane to be input neurons, and all the actions to be output neurons.

Surely at least part of the issue here is that even an LLM operates in two digit tokens per second, not to mention extra tokens for "thinking/reasoning" mode, while a real autopilot probably has response times in tens of milliseconds. Plus the network latency vs a local LLM.

by est

This is a limitation of LLM i/o which historically is a bit slow due to these sequential user vs assistant chat prompt formats they still train on. But in principle nothing stops you from feeding/retrieving realtime full duplex input/output from a transformer architecture. It will just get slower as you scale to billions or even trillions of parameters, to the point where running it in the cloud might offer faster end-to-end actions than running it locally. What I could imagine is a small local model running everyday tasks and a big remote model tuning in for messy situations where a remote human might have to take over otherwise.

by rkagerer

4/14/2026 at 8:12:02 AM

As most others have pointed out, the goal from here wouldn't be to craft a custom harness so that Claude could technically fly a plane 100x worse than specialist autopilots. Instead, what would be more interesting is if Claude's executive control, response latency, and visual processing capabilities were improved in a task-agnostic way so that as an emergent property Claude became able to fly a plane.

It would still be better just to let autopilots do the work, because the point of the exercise isn't improved avionics. But it would be an honestly posed challenge for LLMs.

by Paracompact

4/14/2026 at 7:18:48 AM

I suppose part of the problem with autolanding a small plane is that they have much less intertia and are much more susceptible to conditions.

Large planes are autolanded in normal conditions with oversight of qualified, capable and backed up operator, in harsh conditions they are not used, as far as I understand.

Autoland systems in small planes are emergency systems to land plane with disabled operator in any conditions generally acceptable for flying in that plane.
