关于昨天韩亚航空事故的一种观点

以下节选自flyertalk.com的一个帖子~我简单翻译一下。我不是专业人士,翻译的不好请见谅。

I am both an Airline Transport rated pilot and flight instructor.

我是一名飞行教练,同时是一名持有Airline Transport Pilot License(在美国是最高等级的飞行执照)的飞行员。

What seemed likely yesterday now seems clear. This was purely pilot error. The glide slope of the ILS (Instrument Landing System) was turned off at SFO. This means that the pilot could not use his autopilot for the approach. However, the weather was perfect and visual approaches were what was required. This means that the pilot had to determine his own glide path to the runway.

昨天看起来比较可能的猜测今天已经基本得到证实。这次事故完全是飞行员的错误。昨天旧金山机场着陆引导系统(ILS)中的下滑道引导系统(glide slope)因为故障被关闭。这意味着飞行员不能使用自动驾驶系统来完成航班最后的进近过程。但是昨天旧金山机场的天气非常好,飞行员完全可以目视降落。也就是说,飞行员必须自己计算出下滑道,以正确降落在跑道上。

Plainly he landed short. Indeed, this has all the earmarks of what student pilots show before they learn to do better. When a glide path is coming up short, the response by the pilots must be application of power. That is the only response that works. Human nature unfortunately suggests raising the nose as that creates the illusion that the short glide path is being fixed. Actually that makes things worse as it does not lengthen the glide path; instead it reduces airspeed.

这个飞行员降落得太早了。这是典型的初学者一开始会犯的错误。当下滑道计算失误,导致降落点太早,这时候飞行员的正确反应必须是加大引擎的推力。这是唯一可以修正错误的方法。遗憾的是,人们的直觉反而是要抬高机头,因为这产生一种能够修正下滑道的错觉。事实上抬高机头把事情弄得更糟,它不能延长你的飞行距离,反而降低了你的空速。

So what do we see here: throttles at idle position and airspeed 7 knots too slow.

这就是我们昨天所见到的,油门处于空挡,而空速比正常情况下小了七节(knots)。

Honestly this is inexcusable incompetence in the flight deck. These are mistakes that student pilots make in Cessna 150s before they are taught to do better. Not in an airliner.

实话说,这是驾驶舱出现了不可饶恕的错误。这种错误应该是初学者在切塞纳150(一种训练机型)上会犯的错误,并应该已经得到纠正。这不应该出现在客机飞行员身上。

Seems without the crutch of a glide slope and an autopilot coupled approach, this crew was not up to the job.

在我看来,没有了下滑道引导系统和自动驾驶的帮忙,这个机组没有足够的能力来应对(目视降落的任务)。

Tragic, sad, inexplicable, incompetent.

杯具,遗憾,不可饶恕,不称职。
