    Air India 787 crashes on take off

    They are digital inputs. And there is a voting system which then links to the EICAS. Its called the EEC (electronic engine control). Which we have 2 channels per engine with a 3rd emergency. And if 2 go leaving only the emergency the other engine can support the other with its spare. You...

    It definitely doesn't solely, its one of these triple redundancy systems for FBW. Although quite how it works I have no clue. I am actually hoping that someone that does, is going to show up and explain.

    The region has issues with qualifications not just aviation and corruption. I must admit Tug has just voiced a possibility I had been considering as a possibility with no proof. to note the Engine FEDEC are powered by its own perm magnet generator so the aircraft electrics failure shouldn't...

    i don't think they could shut them down together so there is no yaw if they did. I suspect its like the dual engine shut down on landing on the A220 when there is a throttle failure caution. We shall see how many and what type of MEL items were open.

    By pulling upwards and then moving to off then releasing. It's not something you can do inadvertantly. The A220 is the same. You get a skin calus on your index finger lifting it. There are some issues with liquids being spilt on those switches and engine shut downs. I can't remember the type...

    The bus ties decoupling due to fault can produce an alarming amount of noise. Thanks for correcting engine type.

    Seems reports are coming out of electrical issues on the previous sectors. It was Trent RR engines.

    Anyone seen if it was GE or RR on it? I think the Trent had an issue with thrust reversers and uncommanded shutdown on landing.

    Air India 787 crashes on take off

    The lot of runway is a function of derated power. We used an app to calculate the departure performance which optimises things for minimum engine wear and fuel used. And you do get very near the end when you rotate sometimes. Flap 2 is our normal departure flap setting. Anything more than...

    Definitely something up with electrics. Normally the No1 radio is wired to the emergency battery bus. But the crew might have been too busy to think to use it. It's reported and you can get the recording of the mayday radio call. There seems to be multiple issues but what's the primary...

    787 had battery issues which it was grounded for. But not much else. If a li ion battery blew up i have zero clue if that could cause the fuel valves to close.

    That does sound like the rat is out... Only heard it once on real life in 24 years. The automatic trigger for that is complete electrical failure. To turn both engines off is almost impossible to do by accident.

    Seems someone walked away from the crash. Reports a loud bang then the crash. "A British father has miraculously survived the Air India plane disaster believed to have claimed the lives of hundreds of people in India. Vishwash Kumar Ramesh, 40, spoke from the safety of a hospital bed after...

    American Airlines plane diverted because it was too big for the airport

    The 650$ EU compensation for a delay more than 3 hours will be in play here I susepct. It mounts up rapidly if its the airlines fault.

    As an aside it's a very picturesque area. You fly round a big volcano on departure depending on the runway. In use.
