飞机跑道

THE connection between an 18th-century savant called Joseph-Louis Lagrange and the problem of landing safely at Hong Kong International Airport may not, at first, be obvious. But there is one. Hong Kong airport is notorious for rocky and sometimes aborted landings caused by the disturbed air flow from nearby mountains. Though laser technology is deployed alongside its runways to monitor changes in wind speed and thus forewarn pilots, that is often not enough. What is needed is a better understanding of the theory of the winds themselves.

十八世纪的学者Joseph-Louis Lagrange同香港国际机场飞机的安全降落之间乍观起来并没有明显的联系，但是，实际上是有的，香港机场以其路面坚硬、附近山上吹来的空气涡流常常飞机降落的被迫取消而臭名昭著，尽管沿着飞行跑道部署了最新的科技手段以监视空气风速的变化，从而给飞行员以提前警告，但这常常是不够的，需要的是对风本身理论上的更好的理解

And the position vector of aircraft is computed too if the runway width is known. A complete drive of the algorithm is given based on imaging geometry.

由此可直接算出飞机的姿态向量，若跑道的宽度已知，还可以算出飞机的位置矢量。

Preflight -This portion of the flight starts on the ground and includes flight checks push-back from the gate and taxi to the runway.

飞行前的预备工作——这部分工作是在地面完成的，包括飞机的检修，飞机从登机口拖出来并驶往跑道。

High oil prices have sealed the fate of the four-engined aeroplane, along with rules that allow twin-engined aircraft to fly long-haul routes provided the nearest landing-strip is no more than two hours away.

高油价决定了四引擎飞机的命运，也使双引擎飞机可以飞长途路线，只要最近的起降跑道不超过两小时路程。

For most of the past two decades the state of Afghanistan's air power has been graphically depicted by the hulks of destroyed and cannibalised Soviet aircraft littering the side of the runway at Kabul International Airport.

过去二十年的大部分时间中，喀布尔国际机场跑道边上废弃的飞机外壳和拆东墙补西墙的苏制飞机成了阿富汗空军状态的形象写照。

BA plane to bounce on the Jamaican tarmac, run off the end of the strip, veer partly across a roadway and end up pancaked in the sand - by some accounts with its nose barely 10 feet from the edge of the water.

飞机在金斯敦机场着陆时失去控制，冲出跑道撞毁围栏，在一条道路上打滑，最后停在海滩上。一些人说，飞机机头距离海边还不到10英尺。

A Lufthansa flight taxiing for takeoff in New Jersey clipped the (3)___ of another plane last night.

昨晚一架汉莎飞机在新泽西滑翔起飞时，夹在了另一架飞机的跑道上

Dun, the Pilot coach who was directing the plane to land safely told him: You must make your plane to aim at the runway, then turn the engine off and make especially the plane to keep a balance.

指挥飞机安全降落的飞行教练告诉他对准跑道后关掉引擎，并格外要他保持平衡，如果下降的倾斜度太大飞机就会撞在地上。

Another pass. The landing runway is tilted at a 14-degree angle to the rest of theship, so bolters like this can take off from the side of the ship instead ofplowing into the planes on the other end of the deck.

着陆跑道要比航母飞行甲板的其它部分倾斜14度，这样急速飞驰的飞机可以在飞行甲板的一侧起飞，而不至于冲向停在甲板另一端的飞机那里。

Operational data needed for noise contour development includes aircraft type, runway use/direction of operations , flightpath identification, and time of day.

为噪音研究所提供的运行数据应包括以飞机类型、跑道运行方向、飞行轨迹、飞机识别标志和运行时段。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
