It's not always a smooth and pleasant landing for airplanes.

飛機的降落不總是那麼平順愉快。

分詞構句

Intense, strong winds can affect the position of how planes land on the Runway, making it look like the plane is literally landing sideways.

強勁的陣風會影響飛機在跑道上的降落位置，讓飛機看起來像是真的側著降落。

Here's how planes land sideways in high winds.

這就是飛機在高風中側著降落的方式。

Landings like this actually have a name, crabbing.

這種降落方式其實有個專有名詞，叫做 crabbing。

The name comes from the way crabs walk sideways across the beach.

這個名字來自螃蟹橫著走路的樣子。

That's kind of what the airplane looks like when it's landing this way.

這跟飛機這樣降落時的樣子有點像。

Crabbing is usually needed because of high crosswinds.

crabbing 通常是因為強勁的 crosswinds 所需的。

The wind can either be blowing straight down the Runway or 90 degrees to the Runway or somewhere in between.

風可能是筆直吹向跑道，或是與跑道成九十度角，或是在兩者之間。

And usually it's somewhere in between there.

He teaches aeronautical science at Embry Riddle Aeronautical University and is a retired airline pilot.

他同時也是一位退休的 airline pilot，並在 Embry Riddle Aeronautical University 教授 aeronautical science。

Landing in a crosswind situation requires a couple of different maneuvers.

在 crosswinds 的情況下降落，需要一些不同的 maneuvers。

When we're at altitude, the aircraft just flies in a craft and we just go across kind of sideways.

當我們在 altitude 的時候，aircraft 會以一種 craft 的方式飛行，有點側著移動。

Once we get down to the ground, we can't land with the aircraft in a craft because that's going to put a lot of stress on the outside of the landing gear and could actually cause the landing gear to collapse if we put too much stress on it.

一旦我們降到地面，就不能讓 aircraft 用 craft 的方式降落，因為那樣會對 landing gear 外側造成很大的壓力，如果壓力太大，甚至可能導致 landing gear 塌陷。

Whenever there's a crosswind, there's a lot of turbulence.

只要有 crosswind，就會有很多 turbulence。

So it's not like the pilots are flying through a slight summer breeze.

所以這可不是像飛行員在微風中飛行一樣。

Of course, the ultimate goal is for the aircraft to land straight where the nose of the plane is in alignment with the stripe that's down the Runway.

當然，最終的目標是讓 aircraft 直直地降落，讓飛機的機頭與 Runway 上的標線對齊。

Those crosswinds sure make it challenging.

那些 crosswinds 確實讓事情變得很有挑戰性。

There is an angle to that, you know, it's a force vector.

這是有個角度的，你知道，這是一個 force vector。

So the direction and the intensity that it's coming at will determine how much input we have to put into the aircraft's flight controls.

所以風吹來的方向和強度，將決定我們需要對 aircraft 的 flight controls 輸入多少力道。

As the plane comes in, the pilots are actively controlling it so that it's in the perfect landing position.

所以飛機進場時，機師們會積極操控，讓飛機處於完美的降落位置。

But when a gust of wind comes at the wrong time, it will cause the pilot to execute a go around instead of landing.

但如果一個不合時宜的 gust of wind 出現，就會讓機師決定 execute a go around，而不是直接降落。

If the crosswinds are severe enough, around 45 miles per hour or so, the pilot does not have enough control to straighten the airplane out and land.

如果 crosswinds 太強，大概時速 45 英里左右，機師就沒辦法把飛機喬正來降落了。

If this happens, the pilot will abandon the approach and divert the plane to another airport.

如果真的發生這種情況，機師就會 abandon the approach，然後 divert the plane 到另一個機場。

These strong winds can prevent the planes from taking off at an airport.

這些強風有時候也會讓飛機無法在機場起飛。

That's sometimes where those flight delays come in, and we all love those.

這也就是為什麼有時候會發生 flight delays，而我們都很喜歡這樣。

So exactly how do the aircrafts land in these conditions?

那麼，飛機在這種情況下到底要怎麼降落呢？

Last minute, we want to move the nose of the aircraft parallel with the Runway.

在最後一刻，我們要讓 aircraft 的機頭和 Runway 平行。

But soon as we do that, the aircraft's going to start blowing off to the side of the Runway with the wind.

但我們一這麼做，飛機就會被風吹離 Runway 的一側。

So in order to counteract that, we lower the wing, the upwind wing.

所以為了抵銷這個影響，我們會降低順風側的機翼。

We lower the wing and straighten the nose out.

And a perfect crosswind landing will be when the upwind wheel touches down first, the aircraft is straight down the Runway, and

而完美的 crosswind landing 就是順風側的輪子先落地，飛機沿著 Runway 直線前進，

then the second wheel will come down after that.

然後另一側的輪子再跟著落地。

Finally, the plane is on the Runway and heading to the terminal.

最後，飛機就安全地降落在 Runway 上，朝航廈前進。

Some of your best landings are actually made when it is in challenging conditions, because you are on your A game when you're doing this, and

其實你一些最棒的 landing，都是在有挑戰性的情況下完成的，因為你全神貫注，

you're completely engaged and actively controlling the airplane.

So actually, some of our best landings are made when we are in these crosswind landing situations.

所以其實，我們一些最棒的 landing，都是在這種 crosswind landing 的情況下完成的。

So if you're ever on a plane that feels like it's landing sideways, feel safe knowing the pilots have the situation totally under control.

所以如果你搭飛機時，感覺飛機好像是側著降落，請放心，機師們已經完全掌控了情況。
