I’m interested to see what they come up with to solve the issues of cold environments at altitude and refueling between legs.

I fix giant metal birds that light themselves on fire and scream really loud to fly across the sky. The kingdom heavily regulates who fixes them, how they fix them, and who flies them to make sure everyone is safe.
It’s also very easy to run an AI image generation tool locally using open source models.
Considering that writer is pumping out multiple articles a day, they most likely are to some extent.
Totally fine. The inside window isn’t the important one. It’s just a plastic cover for the real window on the outside.
But in this case, they’re not. Plus, the crew are going to be the ones determining if their VOR/DME makes sense or not.
First, they have to align on the ground. You initialize them with your current known position (usually by GPS or your known airport/gate spot). Then, you wait for them to synchronize with the Earth’s rotation. If you’re far north, like in Alaska, this could take half an hour. If you’re close to the equator, it could take 5 minutes. Once they’re ready, from that point, any movement you make, it will know where you are and where you’ve been.
If you spin up a gyro and begin moving around, it will maintain it’s starting position. You can use this deflection to calculate direction. If you know how fast you are going and for how long, you’ll have your position.
Mechanical gyros drift. It’s the nature of a world with friction. Newer IRUs use laser gyros, so the only real drift they have comes from extremely minute rounding errors.
If it’s a smaller plane (such as a CRJ / ERJ) with only one IRU, it will not be able to determine if GPS is valid or not, so the drift correction gets spoiled.
Large commercial aircraft are using 3 IRUs, with newer aircraft using ADIRUs. If GPS does not agree with the three IRUs, the GPS data is thrown out. If the GPS is within tolerance, correction is applied. You could build up very small errors over a long distance, but you should still be pretty close to the airfield when you get there.
ADIRUs will throw out bad GPS data if it disagrees with multiple IRUs, hence why there’s usually 3 on the aircraft. That being said, if the GPS is close enough to the three, then correction will still be applied.
If they’re using the older IRUs, the drift is corrected via redundancy and not GPS. Usually pilots will report drift based on their final IRU coordinates compared against GPS. Even then, they should still be checking their course with VOR.
Yes. Most of commercial navigation systems rely on the IRUs as a primary source of position data, and they’ll usually have 3 of them. VHF is used by the crew to confirm that the aircraft is on track by referencing VOR stations, though these are slowly being phased out due to GPS.
That being said, a single traditional IRU can have up to 2km of drift over a 2 hr flight (at which point it’s removed from service and replaced). When used in combination with two other IRUs, the error is dramatically reduced. Traditional IRUs are gyroscopically mechanical in nature and do not talk to GPS.
Now, that being said, the new standard is called an ADIRU (ADvanced IRU), which ties in with GPS and features laser gyros. They’re extremely accurate and have essentially zero drift, plus multiple redundant components within each unit.
That just means you can’t use autoland in low visibility conditions. Modern IRUs (inertial reference unit) are highly accurate laser gyros that can use GPS for correction, but will throw out the data if it doesn’t make sense. Navigation won’t be affected much, and autoland (if used) will still rely on VHF guidance.
We may have the same employer.
In addition to switching companies, my employer is also bragging about a new health plan with $0 monthly cost to the employee, while being completely silent on that new plan covering absolutely nothing aside from virtual appointments through an app sponsored by the insurance company.
I wonder if it’s going to be as terrible as their Fire OS.
YouTube compresses the video as soon as it's uploaded, so it's unlikely you can obtain any sort of lossless download. You may be able to get a .wav or similar download of a video's audio track, but there will still be compression losses from the YouTube side.

Home internet data caps WERE a thing of the past when Obama appointed Tom Wheeler as FCC chairman, who then pushed rulings to classify ISPs as a public utility and started enforcing net neutrality. Companies that didn’t play ball started getting fined until they fell in line. Being a former executive for a major ISP, he was very familiar with the anti-competitive practices and underhanded tricks those companies had been using for years; and he used those practices against them to finally make some pro-consumer progress for internet access in the US.
Then, Trump came in and put Ajit Pai in charge of the FCC (no joke, my phone kept auto correcting his name to Shit Pie). Anyways, Shit Pie tore down those rulings and undid all those years of progress as part of the Trump administration’s anti-Obama initiative. Even though it was proven time and again that what he did was directly against public opinion, and that ISPs were flooding the public commentary with bot posts(some even made by dead people); Shit Pie continued to meme about himself and drink from an obnoxiously large Reese’s coffee mug while doing so. At this point, every provider of internet services has added back data caps in the US, and they have continued to increase their prices to maintain that 99.9% profit margin. They’ve also locked down more areas to prevent municipal broadband services from forming, and they’re even pushing for legislation to prevent them from ever happening.
The current administration has done absolutely nothing. In fact, they’ve been so unremarkable, I have no idea who is in charge of the FCC, and I don’t feel like looking it up.
Also the fact that they are made of metal. Heck, just the idea of lighting a fire below deck of a ship made of cast iron back in the civil war was seen as something insane.
