Comment Re:Directly monitored switches? (Score 1) 36

There is a possibility of a short-circuit causing an engine shutdown. Apparently, there is a known fault whereby a short can result in the FADEC "fail-safing" to engine shutdown, and this is one of the competing theories as the wiring apparently runs near a number of points in the aircraft with water (which is a really odd design choice).

Now, I'm not going to sit here and tell you that (a) the wiring actually runs there (the wiring block diagrams are easy to find, but block diagrams don't show actual wiring paths), (b) that there is anything to indicate that water could reach such wiring in a way that could cause a short, or (c) that it actually did so. I don't have that kind of information.

All I can tell you, at this point, is that aviation experts are saying that a short at such a location would cause an engine shutdown and that Boeing was aware of this risk.

I will leave it to the experts to debate why they're using electrical signalling (it's slower than fibre, heavier than fibre, can corrode, and can short) and whether the FADEC fail-safes are all that safe or just plain stupid. For a start, they get paid to shout at each other, and they actually know what specifics to shout at each other about.

But, if the claims are remotely accurate, then there were a number of well-known flaws in the design and I'm sure Boeing will just love to answer questions on why these weren't addressed. The problem being, of course, is that none of us know which of said claims are indeed remotely accurate, and that makes it easy for air crash investigators to go easy on manufacturers.

The issue is not whether the switches were moved. In the event of a dual engine shutdown, moving the switched off and then on - is the correct procedure to force a re-start. After a short delay for the second one, because electric power was lost, and the RAT only supplies enough power to start one at a time.

Suicidal pilots would not have restarted the engines!

The "did you do that?" comment had no indication of what "that" was that has been published. It is pretty clear that multiple actors are engaged in muddying the waters.

"The truth will out" - but possibly at 40,000 feet over the North Atlantic.

How many RATs does it take to power a data center? enquiring minds want to know!

Journal Journal: Audio processing and implications

Just as a thought experiment, I wondered just how sophisticated a sound engineering system someone like Delia Derbyshire could have had in 1964, and so set out to design one using nothing but the materials, components, and knowledge available at the time. In terms of sound quality, you could have matched anything produced in the early-to-mid 1980s. In terms of processing sophistication, you could have matched anything produced in the early 2000s.

It's far from indisputable. Indeed, it's hotly disputed within the aviation industry. That does NOT mean that it was a short-circuit (although that is a theory that is under investigation), it merely means that "indisputable" is not the correct term to use here. You can argue probabilities or reasonableness, but you CANNOT argue "indisputable" when specialists in the field in question say that it is, in fact, disputed.

If you were to argue that the most probable cause was manual, then I think I could accept that. If you were to argue that Occam's Razor required that this be considered H0 and therefore a theory that must be falsified before others are considered, I'd not be quite so comfortable but would accept that you've got to have some sort of rigorous methodology and that's probably the sensible one.

But "indisputable"? No, we are not at that stage yet. We might reach that stage, but we're not there yet.

Not really. If you ask it what's going on in the news then you'll get an up-to-date response, because it knows in that instance to check and summarize the news rather than just generating something from its LLM.

And if you ask Gemini what time it is you'll get the right answer, for the same reason.

The fact that ChatGPT fails to do this is a problem with ChatGPT, not any inherent problem for AI. Probably in response to this embarrassing article it will be fixed within a couple weeks.

That's a good point. Here on /. I can assume people know what open world games are. Out in the real world movies are probably the better analogy.
