    That just means that the wind had swung a bit more to the north.

    Ask The Pilot

    Because even with the headwind, 250 would be too short for the operation. Because wind isn’t the only issue with the weather. Looking at the videos, the approaches are all in ‘actual’ IMC, which means that you’ll need greater separation between aircraft, and you’ll need to be careful of...

    Air India B787 crash Ahmedabad

    Well, she isn’t alone there. It is FADEC…. Anyway the two terms overlap. Full authority digital engine control, and electronic engine control. I doubt that you could buy an airliner now without FADEC. People have locked in on TCMA, but I suspect that it isn’t the only thing that’s capable of...

    So... what car do you guys drive when not flying?

    Presumably, you keep the diesel and batteries right next to each other.

    Air India B787 crash Ahmedabad

    Oxygen bottles have been in service forever. As far as the ATSB were able to discover, only one has ever decided to go bang whilst sitting and minding it's own business. You just need the holes to line up in the right way, or in the case of software, the right sequence of events, which may be...

    Not an expert on aviation, but not just any lawyer either.

    Air India B787 crash Ahmedabad

    “Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth.” Assuming the engines have shut down, which seems reasonable given the outcome, and what can be seen and heard, then you’re left with a Sherlock Holmes problem. Engines are reliable, and they’re...

    So... what car do you guys drive when not flying?

    Funny coincidence. My nephew sent me a refererence on Carsales, for a HSV GTS. I was the original owner of the car, and sold it 29 years ago. So, then I had a look around the site, and found another car that looked pretty familiar. A bit of research and found that it too was mine. VW R32 that I...

    Wouldn’t be much point in having its own power supply, if no data was coming in, though perhaps that’s telling in itself. If all of the buses are dead, in an electric jet, then that’s about it. But, the fact that we see the aircraft remaining stable in roll, and making some pitch changes, means...

    Read the article I referenced in #351.

    Because it will be wrong, no matter how long we wait.

    Ask The Pilot

    I’m surprised that any pitot heat MEL relief would be available at all. I wonder if it came with any caveats. I know that QF engineers attempted to use a similarly restricted MEL on a domestic flight, when the MEL said “no icing conditions”. They didn’t seem to understand that just because it’s...

    Air India B787 crash Ahmedabad

    Which is what you'd actually expect. Those looking for the smoking gun are struggling though, because it looks like a dual engine failure, but it's almost impossible to explain how that could happen. I have a theory about aircraft accidents, to the effect that they seem to become stranger, and...

    Air India B787 crash Ahmedabad

    It’s interesting if true, but I’m not convinced that looking for the smoking gun is a great idea, with such limited information. Nevertheless, a default position of ”shut down” seems inappropriate for anything that flies. Whether that’s really correct, I don’t know.

    Air India B787 crash Ahmedabad

    Possibly sounds strange, but the non flying pilot might have had a few seconds when he wasn’t doing anything…in large part because there’s nothing you can really do in this sort of situation. Again, the timing of the call, relative to the aircraft’s position will be relevant. And pilots, can...

    Would you fly at a less convenient time to get a nicer plane?

    I'll take a less convenient time to get an AB.

    It's interesting, though his presentation has reached the breathless level. My fear would actually be that they don't. Basically a tree of possibilities with a branch missing. I'm finding it odd that they're going to the conclusion stage, though I have no objection to being given possible...

    Air India B787 crash Ahmedabad

    I've just watched that all the way through, and I'm disappointed that he comes to the final 'conclusion' that he does. I don't think he has anything to really base it on, and is suffering from the same youtuber race that he mentions at the start. It's reasonable to look at what we can see as...

    Air India B787 crash Ahmedabad

    That does leave us with another question. I’ve asked, but not gotten a definite answer. We know that the first action in the gear retraction sequence is the repositioning of the gear truck, but I don’t know what the no hydraulics rest position of the truck is. I suspect that it would also be the...
