    Jeju Air Flight 2216 Crashes in South Korea

    It’s definitely there from one angle. It’s the right engine, which is the one that is shown having a compressor stall earlier. It’s quite possible for a jet engine, to run, but not produce power, or to start compressor stalling as you increase the power. But, if running, even at low power, you’d...

    Jeju Air Flight 2216 Crashes in South Korea

    I specifically said ADSB, because we know the exact time that it dropped out. Whilst it’s logical to assume, we actually don’t know that that is the same time that the recorders stopped, or if the two recorders stopped at the same time as each other. So you could have all three stopping at once...

    Jeju Air Flight 2216 Crashes in South Korea

    It's all about energy. At the point the ADSB stops, he's barely got enough to get to the runway without any turn at all. But, not only does he manage a 180º, but he lands at a speed appreciably faster than he his at the end of the recording. The energy to do that has to have come from the...

    Jeju Air Flight 2216 Crashes in South Korea

    I'm sure it's been played to death in various sims around the world already. I saw that early in the piece, and then a denial. I don't think it fits the 4-5 minute timeline, but it would make sense if they had a bit more time.

    SPITFIRE! I want to do this someday

    To fly it? Young me certainly would have been. As for the reporter, I don't think he expected quite that low. My guess is that they'd done the shot a couple of times to get the timing, and the aircraft was lowest on that run. Flying very low isn't necessarily as dangerous as you might imagine...

    Article: Are Ground Handlers Gaming Baggage Delivery KPIs?

    Ah, KPIs. What a load of the proverbial. I can see the handlers doing all they can to worsen the KPIs, as any benefit derived from them would go to 'management' and not the workers.

    Jeju Air Flight 2216 Crashes in South Korea

    Loss of both generators pretty much has to be tied with engines. But, it cannot possibly have happened before the GA, as you simply cannot go around without them. Well, not for long enough, anyway. From the point where data is lost on the approach, the aircraft barely had enough energy to...

    Jeju Air Flight 2216 Crashes in South Korea

    Australia is a minnow, so if it came out with something that wasn’t already required elsewhere, we simply wouldn’t be getting new aircraft. But, you’re missing the point. It simply doesn’t matter if the recorders are powered, if the data sources aren’t powered. So, you need to provide backup...

    Jeju Air Flight 2216 Crashes in South Korea

    Why? You don't think a double engine shutdown/failure would hurry them up enough. You could get smoke in the cabin (from your cooked birds) but that's not a fire, and requires no more response than you'd already be doing. And you'd never get to that checklist (or even answer the phone) anyway...

    Jeju Air Flight 2216 Crashes in South Korea

    Actually I think it went to the NTSB. And Boeing don’t make flight recorders, so if you want to get the maker involved, it would probably be someone like Honeywell. I think you can be pretty confident that there would be no tampering. Why do you need a fire? Actually engines will often run...

    Jeju Air Flight 2216 Crashes in South Korea

    It’s a very telling bit of information. Power to the recorders will be drawn from a couple of the aircraft buses (not the same one for each recorder), and it will stop any recording if that bus is unpowered. The buses themselves are powered by the engine driven generators, and the APU. The...

    EY plane stuck on runway at MEL for 14 hours after tyres burst

    I theory I guess it could, but it isn’t. Normally with braking, you simply manually put in a little more pressure than the automatic system (via the pedals) and it it will disengage, but in RTO, as it’s already sending maximum pressure, that won’t work. But, if you select something else on the...

    What to do about noshows?

    Back in my early days with the airline, and I was flying with a very no nonsense Captain. He hated people who intentionally held up the aircraft, as they visited duty free, in the knowledge that as their bags were on board, they could afford to be late. You know who you are, and they are not...

    EY plane stuck on runway at MEL for 14 hours after tyres burst

    It's not an instant effect either, so I'd expect the tyres were still all happily inflated when the aircraft came to a halt. The heat would have continued to soak in from the brakes, and eventually the plugs would go, deflating the tyres. You should have a few minutes in which you can safely...

    I had a chat to a couple of the cabin crew, and they remembered a young lady traveling alone.

    Jeju Air Flight 2216 Crashes in South Korea

    Yes, good question. But, we don’t know if they went around before the strike or after. CRM is a process that has, in many ways, made flying safer. But in some ways too, it has become a bit of a “talk-fest”, with some protagonists thinking it makes the coughpit democratic. Quite simply there are...

    Jeju Air Flight 2216 Crashes in South Korea

    Another point that is possibly relevant, if you're trying to restart engine(s), then there's a minimum speed, which will be something in the order of 240kias. If you're slower than that, then you need the APU for bleed air. So, you need to start the APU, and make the correct bleed selection.
