If I’m not mistaken, there was also an issue with the enable/disable option in the system and it turned out that it didn’t work even for the airlines who paid extra for previously standard (and now required by law because of this bullshit) functionality.

Remember the first time 737s were dropping out of the sky due to departures from old safety standards Boeing lobbied the FAA for and Boeing covered it up? No one went to jail over all those deaths either.

Which motorcycle was it that wouldn't start if it was at 0°C because the zero was an invalid return for its temperature sensor to clear it to start?

I'm pretty sure they just send the whole kit and kaboodle - after all, diabetics tend to be older, and thus not exactly technology-literate. The battery and SIM were already installed when I got it (isn't that a no-no for removable Li-Ion batteries?), it was literally turn it on and start using it, it just asked for my name. When I registered it online, I was just asked for the serial # of the meter itself (way too short to be an IMEI). I'm sure the SIM card is associated with the meter somewhere. It's been so long since I had a phone with a removable battery that I didn't even think to try popping the back off. Since I managed to get it into fastboot, I wonder what would happen if I did a factory reset.. ADB didn't recognize it even in fastboot though (PC didn't either, it just showed "Android" with no drivers installed).

That's the same reason that roborace car decided to bury itself into the pit wall as soon as it started off. There was an error outside of what the car was actually looking for so just ignored it, turns out it was a fairly important error to just ignore it hence the car kissing the wall.

My friend's a pilot and he was saying it is drilled into you to rely on your instrumentation because as dumb as you think it is, it's real easy to get disoriented and not be flying how you think you are. "The auditory system, vestibular system (within the inner ear), and proprioceptive system (sensory receptors located in the skin, muscles, tendons and joints) collectively work to co-ordinate movement with balance, and can also create illusory nonvisual sensations, resulting in spatial disorientation in the absence of strong visual cues." So you think you're flying flat but are banked over and such. ...the problem is when the instrumentation is wrong.

It's also a thing in scuba diving, because of the feeling of weightlessness it's very easy to become disoriented and lose track of what direction is "up", especially in conditions where the water isn't clear. Luckily underwater you can just blow some bubbles to reorient yourself.

So you think you're flying flat but are banked over and such. yep https://en.wikipedia.org/wiki/Atlas_Air_Flight_3591 quote:The NTSB determines that the probable cause of this accident was the inappropriate response by the first officer as the pilot flying to an inadvertent activation of the go-around mode, which led to his spatial disorientation and nose-down control inputs that placed the airplane in a steep descent from which the crew did not recover. Contributing to the accident was the captain's failure to adequately monitor the airplane's flightpath and assume positive control of the airplane to effectively intervene. Also contributing were systemic deficiencies in the aviation industry's selection and performance measurement practices, which failed to address the first officer's aptitude-related deficiencies and maladaptive stress response. Also contributing to the accident was the Federal Aviation Administration's failure to implement the pilot records database in a sufficiently robust and timely manner.[12] The plane was flying in the clouds with no visual references to the horizon. The pilot bumped the throttle by accident, putting the plane in TOGA (max thrust) mode, and with no external references his brain interpreted the acceleration as the plane pitching up. Thinking the plane was going to stall, he instinctively forced the nose down. That caused the plane to accelerate even more, strengthening the illusion. He kept pushing forwards until the plane hit the ground. All the instruments were operating normally, and if he'd managed to ignore his brain and focus on the attitude indicator, everything would have been fine. When I was learning to fly, the most dramatic example was getting "the leans." Put on the hood and do a bunch of steady turns in one direction, and after a minute or so your brain -- having no visual horizon to calibrate itself -- shrugs and goes "guess this inner-ear information is normal" and you stop feeling the turn. Then when you straighten up, for another few minutes you have the intense feeling that the plane is still banked over, even though you're staring at the attitude indicator saying you're flying level. It takes serious concentration to ignore the sensation and trust what the gauges are saying. Sagebrush fucked around with this message at 19:54 on Apr 19, 2021 |

It's worth noting that analog instruments can fail too and modern displays can be very reliable, although they're generally susceptible to different failure modes. I'm a little leery of it, but hopefully people did their due diligence in testing Here's a PA-46-600TP with full glass cockpit. You can change which displays are looking at what so even if one of the displays fails, you can pull relevant information up on another display and keep flying. If the brains of the flight computer die you're out of luck, but it's not supposed to do that. I'm not familiar with the avionics on it, it may have redundant arguing computers, so it may be more resilient than I'm giving it credit for.

You can see the redundant instruments over on the extreme left. They’re digital, but completely separate from the PFDs in input, processing, and have an independent battery backup. Turns out that digital processing and displays are waaaaaaaay more reliable and cheaper to maintain over the long term than analog instruments.

I'm not familiar with the avionics on it, it may have redundant arguing computers, so it may be more resilient than I'm giving it credit for. The solid-state avionics computer in that plane, which takes a couple of air pressure inputs but does pretty much everything else internally with rugged, shielded electronics, is far more reliable than mechanical gyros and aneroids. Like: when was the last time you heard of a car's ECU just crapping out? Not the infotainment center, but the actual control unit that handles the engine management? This is the same deal but built to an aviation standard. It's true that the screens are more delicate than a glass-faced mechanical dial. But everything in the background is much better.
