A re-upload of American Airlines captain Warren Vanderburgh's 1997 presentation warning that pilots who over-rely on cockpit automation lose manual flying skills and awareness. The uploader adds context from his own flying.

HN brings it up in any thread about autopilot, Tesla FSD, self-driving cars and crashes as the classic lecture on automation dependency.

That is from 2013 (not saying it’s invalid advice, just that it’s not related to current flying schedules). Children of the Magenta Line is a great presentation on automation dependence and quite funny at moments. [VIDEO] (The GPS flight plan track is standardized to be drawn in magenta.)

@scarier2021 · in “Artificial Intelligence in the Cockpit”

I think this lecture ( [VIDEO] ) should be mandatory for anyone trying to improve flight safety with more automation. I think we're already at diminishing returns, and the only way to eliminate accidents caused by over-reliance on automated systems is to cut the pilot out of the loop entirely. Even in general aviation, the low-hanging fruit is elsewhere. That said, this is still pretty cool, and I could see something like it being one component of a much larger fully automated flight management system. Edit: link should be fixed. If I'm still crushing it, the title of the lecture is "Children of the Magenta Line."

"The thing that stands out here the most is the complete lack of control that the crew had over the plane. The crew was managing the computers rather than flying the aircraft ." Perhaps they are "Children of the Magenta": [VIDEO] ... and I cannot recommend this video enough. I am not a pilot and I have no interest in flying nor any particular interest in aviation, generally ... and I find this talk to be fascinating . EDIT: you can jump to 3:35 where he gives a specific example of a situation where pilots need to choose between automation dependency and dropping down a level of automation. He's a really good speaker and you can tell the audience is very engaged.

The "occasional captured lectures" are still pretty strong. Off the top of my head, here are two lectures: [VIDEO] "Children of the Magenta Line" by Warren Vanderburgh [LINK] "Total Synthesis of Vitamin B12" by RB Woodward You may tell me I'm cheating by posting videos that are obviously not "native" to YouTube, but YouTube was the way I found them, how I watch them, and how I share them with other people. OK, so YouTube-native videos are hard mode. Try [LINK] I suppose? I like it. It has life lessons I'd argue are at least as valuable as the videos you're thinking about.

There is relatively well-know presentation from 1997 by American Airlines captain Warren Van Der Burgh called "Children of Magenta" that talked about the risk of crew being too dependent on the guiding magenta-colored lines of the autopilot on their screens: * [VIDEO] * [LINK] * [LINK] Some of the pros and cons of cockpit automation: * [LINK] Generally automation exists on a spectrum, and the pilot should be able to select its level depending on the circumstances: > In Van’s presentation he describes three levels of automation: > *The pilot manually flying the aircraft. > *The pilot using the flight director, autopilot, and autopilot modes to fly the aircraft for a short period of time. For example: Heading select, Flight Level Change, Vertical Speed, Indicated Airspeed, etc. > *The pilot using the FMS to command the autopilot to fly the aircraft for hours at a time. * [LINK]

Perhaps these pilots were "Children of the Magenta"[1] ? These AA instructional videos by Captain Vanderburgh are fascinating - even to a non-pilot like myself. They are especially relevant as we dip our toes into automobile auto-pilot and the "automation dependency" that comes along with it. Of particular note in this video: @ 12:30: "... tactily connected to the airplane ..." @ 14:15: "... we see automation dependent crews, lacking confidence in their own ability to fly an airplane are turning to ther autopilot ..." @ 17:35 - 18:15: (just listen) [1] [VIDEO]

@throw0101d2024 · in “JAL A359 at Tokyo collided with Coast Guard DH8C on runway and burst into flames”

> Driving doesn’t require an advanced degree in physics. It’s mostly a mish mash of fairly mundane tasks. Generally not wrong, but when it becomes non-mundane, it can become so in a hurry. This is why I'm sometimes skeptical about statistics that say " x% of airplane crashes are human error ". Well maybe, but by the time the humans get involved the automated systems have often thrown up their proverbial hands and digitally exclaimed " Jesus take the wheel ". I think having computers take over the mundane parts may help collision rates as people can get numbed and bored by the monotony. One has to be careful about having the right level of automation and control for the given situation, as per the famous "Children of the Magenta Line" presentation: * [VIDEO] > “Children of the magenta line” has become shorthand for pilots who manage and monitor systems but lack the stick-and-rudder skills to fly the airplane with authority. You may hear it wielded as an epithet in a discussion of “real pilots” versus “kids these days.” But in many cockpits today, automation illiteracy may be as dangerous as automation dependency. Vanderburgh’s insights shouldn’t drive us to reject automation altogether, but rather put it in its proper place in our pilot toolkits. Just as you should hand-fly regularly to keep your stick-and-rudder skills sharp, you should also practice using the technology available in the aircraft you fly. * [LINK] * [LINK] * [LINK] * [LINK]

@conartist62024 · in “Boeing Passenger Jet Nearly Crashes Because of Known Software Bug”

It's actually the right way of thinking! When high-level automation fails you, messing around with the high-level system in a critical moment would probably be your death. Debugging takes minutes not seconds. This is why pilots are trained to drop from a high level automation to a lower one when necessary. Like most learnings about piloting, this insight was purchased with a lot of blood. If you want to know more, check out Children of the Magenta Line: [VIDEO]

@wat100002025 · in “Why was there a wall near runway at S Korea plane crash airport?”

There are numerous past examples of this sort of thing. Automation in aviation is really hard to get right. If the automation can fail then the pilots need to be able to perform whatever it was going to do. If the automation fails rarely then the pilots may not get enough practice. But if the automation normally does a better job than the pilots, there’s a tension with letting them get more practice on real flights. A recent(ish) example is the Asiana crash in SF. They had pretty much perfect conditions for a hand-flown visual approach, but they were out of practice, got behind the airplane, and it snowballed. There’s an excellent lecture about this called Children of the Magenta Line. The magenta line being the flight path or direction indicator on an autopilot, and the discussion is about pilots who constantly reconfigure the autopilot to direct the plane instead of just taking over.

@rsync2025 · in “Flight disruption warning as Airbus requests modifications to 6k planes”

Both unsophisticated lay observers and capital/owners tend to fault operators ... for different reasons. Accident studies and, in particular, books like _Normal Accidents_[1] push back on this assumptions: "... It made the case for examining technological failures as the product of highly interacting systems, and highlighted organizational and management factors as the main causes of failures. Technological disasters could no longer be ascribed to isolated equipment malfunction, operator error, or acts of God." It is well accepted - and I believe - that there were a multitude of operator errors during the Air France 447 flight but none of them were unpredictable or exotic and the system they were tasked with operating was poorly designed and unhelpfully hid layers of complexity that suddenly re-emerged during tremendous "production pressure". But don't take my word for it - I appeal to authority[2]: "Automation dependent pilots allowed their airplanes to get much closer to the edge of the envelope than they should have ..."[3]. or: @ 14:15: "... we see automation dependent crews, lacking confidence in their own ability to fly an airplane are turning to ther autopilot ..."[4].

@Animats2025 · in “AI and the ironies of automation – Part 2”

Bainbridge [1] is interesting, but dated. A more useful version of that discussion from slightly later is "Children of the Magenta", [2] an airline chief pilot talking to his pilots about cockpit automation and how to use it. Requires a basic notion of aviation jargon. There's been progress since then. Although the details are not widely publicized, enough pilots of the F-22, F-35, or the Gripen have talked about what modern fighter cockpit automation is like. The real job of fighter pilots is to fight and win battles, not drive the airplane. A huge amount of effort has been put into simplifying the airplane driving job so the pilot can focus on killing targets. The general idea today is that the pilot puts the pointy end in the right direction and the control systems take care of the details. An F-22 pilot has been quoted as saying that the F-22 is far less fussy than a Cessna as a flying machine. For the F-35, which has a VTOL configuration (B) and a carrier-landing configuration (C), much effort was put into making VTOL landing and carrier landing easy. Not because pilots can't learn to do it, but because training tended to obsess on those tasks. The hard part of Harrier (the only previous successful VTOL fighter) was learning to land the unstable beast without crashing. There were still a lot of Harrier crashes. The hard part of Naval aviator training is landing on a carrier deck. Neither of these tasks has anything to do with the real job of taking a bite out of the enem

Hot take but I feel like Tesla owners (hell, anyone with 'autonomous driving' vehicles) need to see some kind of modern lecture based on the Children of the Magenta talk on automation dependence in aircraft. Mandatory, before you can trigger the system on. FSD has built this generation's newest children of the magenta line. [VIDEO]
