  • ……角度来看。他做出了迫降哈德逊河的正确决定。一旦下了决心,剩下的就是一段漫长的滑翔而已。空域绰绰有余。空中客车全套飞行控制系统承担了大部分操作。去读读朗格维舍(Langewiesche)写的《电传操纵》(Fly By Wire),里面对此有非常详尽的剖析。埃塞俄比亚航空的飞行员当时面临的问题极其棘手。飞机不知为何拼命低头俯冲,标准改平程序毫无用处,……

    …standpoint. He made the right decision to ditch in the Hudson. Once that decision was made, it was just a long glide. Plenty of room. He had the full Airbus flight control system doing most of the work. Read "Fly By Wire", by Langewiesche, which goes into this in great detail. The Ethiopian Air pilots faced a very tough problem. They were nosing down for an unknown reason, the standard recovery procedure didn't work,…

  • 威廉·朗格维舍(William Langewiesche)写航空方面的文章绝对值得一读。想了解更多技术背景,可以读他的《电传操纵》(Fly by Wire),书中解释了为什么“哈德逊河奇迹”的水上迫降其实大半是计算机的功劳。而这篇文章则是在法航447空难的背景下,探讨了驾驶舱自动化的另一面……

    William Langewiesche on aviation is always worth reading. For more background on the technology, read his "Fly by Wire", which explains why the "miracle on the Hudson" water landing was mostly the work of the computers. This article discusses the other side of cockpit automation, in the context of the Air France 447…

  • 那架飞机大部分操作都是由空中客车的增稳控制系统完成着陆的。飞行员的主要职责是拍板决定要在那里降落。去读读威廉·朗格维舍写的《电传操纵》(Fly by Wire)这本书吧。

    That aircraft was mostly landed by the Airbus stability control system. The pilot's job was to make the decision to land it there. Read the book "Fly by Wire", by William Langewiesche.

  • ……采用侧杆制造。但那是为了让飞行员在高过载机动时能够操控。空中客车采用这种设计多年来一直饱受争议。想全面了解空客的控制系统,去读读威廉·朗格维舍的《电传操纵》(Fly by Wire)。但狮航的问题根本不在这儿。空速、姿态、垂直速度、高度,如果飞行员依据的这些信息有误,就有可能失控……

    …produced with a sidestick. But that was so the pilot could control it during high-G maneuvers. Airbus's use of it has been controversial for years. For a good overview of the Airbus control system, read "Fly by Wire", by William Langewiesche. But that wasn't the problem with Lion Air. Airspeed. Attitude. Vertical speed. Altitude. If the pilot is operating on wrong information for any of those, they may lose control…

  • ……颇具讽刺意味的是,威廉·朗格维舍(除了本身是飞行员之外,他在航空领域的声誉还继承自其父亲沃尔夫冈·朗格维舍)就全美航空1549号班机事故写过一本书:https://en.wikipedia.org/wiki/Fly_by_Wire

    …ironically, William Langewiesche (whose reputation for aviation is based, aside from being a pilot himself, on his father, Wolfgang Langewiesche) wrote a book on US Airways 1549: https://en.wikipedia.org/wiki/Fly_by_Wire

  • 参见威廉·朗格维舍的《电传操纵:飞鸟、滑翔与哈德逊河奇迹》(Fly by Wire: The Geese, the Glide, the Miracle on the Hudson)。他指出,在空中客车飞机接近失速时,把操纵杆拉到底才是正确的操作规范。这会告诉……

    See "Fly by Wire: The Geese, the Glide, the Miracle on the Hudson", by William Langewiesche. He points out that pulling the stick all the way back in a near-stall is what you're supposed to do in an Airbus. That tells…
