Real time operating systems are expensive to develop for and require laborious system validation. That's why we decided to use a custom version of Android Jelly Bean running on the latest MediaTek quad core processors featuring Arm Mali gpus. Sensor communications are handled wirelessly with BlueTooth. Be sure to turn off all electronic devices before the flight. :)

You joke, but relying on bluetooth could be reasonable as a redundant system, wires can break too. Probably more as a failure detection mechanism though.

I think it's worth reporting on because this particular issue is known to everyone... you need to cycle the power on the planes every 3 days or else the reset themselves. it's crazy that a modern plane needs to have that happen but it does. the most likely situation is that the plane didn't get shutdown and happened to occur at a level flying situation and the pilots probably freaked out and overflew the plane which…

There was a mandatory patch for that in 2020.

It apparently wasn't mandatory - you could ignore patching it if you kept doing the "reboot at least once every 22 days" directive from the AD 2016...

Mentour Pilot is for people interested in aviation. He does breakdowns/analyses of plane incidents—not just crashes. He's also a certified trainer on at least one type.

It's funny, I was also thinking about Mentour Pilot, both because of the whole discussion here, and because of the post upthread talking about clickbait. I love Mentour Pilot once I get into one of the videos, but looking at all the attention-grabbing (and clickbaity!) stills on his video list makes me have to force myself to remember that it's fine once the video starts.

if you're a Chrome user, consider installing the Clickbait Remover for Youtube extension: https://chromewebstore.google.com/detail/clickbait-remover-f.... or the add-on for Firefox: https://addons.mozilla.org/en-US/firefox/addon/clickbait-rem...

they both do the job well. i've not been mildly irked by clickbait-y thumbnails for ages! great for mental health.

Boeing news … meanwhile doors or flying off planes, planes are dropping mid flight … and the whistleblower is dead. What a strange time. I’m afraid of airplanes (made by Boeing) now.

No. It's a turbulent time with new opportunities.

    When one door closes, an other door opens.  Boeing.

Aren’t turbulence / tailwinds / low pressure zone the only things that can cause a plane to suddenly lose lift and drop? I don’t think there’s any control input that can cause that, this story doesn’t seem to make sense.

Quantas 72 is a flight that experienced a sudden uncommanded pitch-down (-0.8g), causing injuries. https://en.wikipedia.org/wiki/Qantas_Flight_72 So it's in principle possible. But passengers are notoriously clueless, to the point that "there was a go around and I thought we were all going to die" is practically a meme in aviation circles. Wait a few days and see what comes to light once it's investigated.

Good find. I was wondering it was possible.

I don't think defining the size of a market based on how many companies are in it is a very useful metric. If you kept reading your investopedia snippet, you would see that "The airplane manufacturing market is part of the overall airline industry". So saying that "there are only two companies in the industry" is incredibly disingenuous, there are thousands of companies involved in commercial passenger flight. Btw, p…

Ok cmon be nice it’s hacker news we all hate Boeing here - that’s why we’re Hackers :) Yeah it’s relative and the line between “large airliners” and “all passenger aircraft” is somewhat arbitrary, I agree. But I stand by the distinction. The market for large airliners is by far the most important market in aerospace, and it has two companies in it, and the one that’s been doing a decade of record cost cutting has way…

My point is more that: the engines are built by a different company, the tickets are sold by different companies, the airports are run by different companies. I am not making a distinction between large aircraft and medium aircraft, I am saying that Boeing is cog in a much larger wheel, and market dynamics dictate much more than meets the eye. As I mentioned, I am not on Boeing's side and the cost cutting is obviously having impacts. We are arguing about the idea that you think it is a simple fix and common sense fix, and I promise you it isn't. But if I am wrong, I guess I hope to see you in the boardroom soon!

Not really. No airplane was ever grounded by the FAA since the 1970s, when they grounded the McDonnell Douglas DC-10. Since the merger, the FAA has grounded both of Boeing's new planes (The 787 Dreamliner and the 737 Max). Boeing's safety record is objectively declining. They are shipping out airplanes with safety issues that are being found "in production". This is why their planes are being grounded (something that…

Number of groundings depends on the subjective judgement of FAA employees. It's not useful as an objective measure. Christ, Boeing planes used to just spontaneously explode back in the 90s, and the only reason more people weren't killed was that two of the three had the good fortune to happen on the ground.

Modern airplanes should be compared to what is possible in modern times with modern safety standards. If you want an objective measure then compare the Boeing Max planes to their Airbus equivalent: the A320neo.

The A320 neo has had zero fatalities. This is an objective measure that Boeing should be compared against.

AFAIK there have also been zero manufacturing defects at the scale of missing bolts on a door panel.

If you watch The Aviation Herald, this kind of reporting feels a little like trying to write news stories off VAERS data. Crazy shit is happening more or less all the time in planes; the idea isn't that nothing ever goes wrong, but that layered controls prevent injuries or hull losses. It's not that there necessarily isn't a thru-line to these stories. And I read "Flying Blind" like everyone else and share the popula…

What is the value in posting a long, entirely speculative comment like this? It doesn't even appear that you have any credibility in this field. Even if you did, this comment would be useless.

Anyone have the tail number for the airplane involved? Is it CC-BGG? Wondering if there's any way to tell if this is one of the 787s built in South Carolina or in Washington state.

Let me introduce you to two tools! The first is https://aviation-safety.net/wikibase/354285 . A fairly complete database of aviation incidents. The second is https://avherald.com/h?article=51601631&opt=256 , similar to Aviation Safety but has comments and is more like hackernews but for commercial aviation. And yes, tail number was CC-BGG.

Thanks! Either of these tools allow you to see where an airframe was assembled?

Its a 787-9 and was produced in 2015 so I think it could be either. Neither of the two tools I linked tells you which plant.
