飞机为什么会晚点?

WHY are planes DELAYED??? What are SLOTS? Explained by "Captain" Joe

我们要登机
We are going to be on that flight!
我警告你
I WARN YOU
我们要登上那架飞机
WE ARE GOING TO BE ON THE FLIGHT
因为是你们的人告诉我们
Because we were told by your own people
我们可以登机了
that we were okay
所以你必须负责
so you take responsibility
– 并且你要让我们登机- 很抱歉……
and you get us on that flight!- Unfortuna…
没有“抱歉”
THAT IS NO”UNFORTUNATE”!
你才是抱歉的
YOU ARE UNFORTUNATE!
那边是一个愤怒的乘客
That’s an angry passanger right there!
我们都有过这种经历 我承认
We’ve all been there, and I admit,
飞机晚点是件很讨厌的事情
it’s a nuisance – airplane delays.
今天我们要来看一下 飞机晚点的
Today we’ll be looking at five reasons why
5大原因
尤其是为何所谓的“预计离场时间”会导致离谱的晚点
and especially why these so-called”slots”cause these ridiculous delays.
并且 为什么飞行员
Also, why do pilots let
让乘客登机并坐在飞机上等待也不起飞
their passangers sit and wait onboard on the plane and don’t take off,
这和高速公路的交通情况又有什么关系?
and what’s that got to do with highway traffic? So,
让我们少说废话 现在开始吧
let’s NOT delay thisvideo, and let’s get started!
我相信很多人都遇到过这样的情况
I assume many of you have been there –
你在登机口等待
you’re waiting at the gate,
然后登机柜台的女士发布通知
and the lady at the desk makesan announcement saying
你的航班因为技术问题晚点了
that your flight is being delayeddue to technical reasons.
这就是第5大可能导致飞机晚点的原因
So possible reason number 5
技术问题
is”technical problems”.
我知道许多乘客会想
Now,I know that many passangers think
技术故障是飞行员编出来的托辞
that the pilots come up with some technical malfunction,
而晚点是由其他原因导致的
although the delay is caused by other nature.
如果飞行员说是技术问题
If a pilot states it’s a technical issue,
相信我 那确实是技术问题
trust me, there is a technical issue.
通常那只是些小问题
Often the problem is only minor,
但最终可能会影响航行
but could eventually have an impact on the flight.
比如驾驶舱里一个小灯泡坏了
I’m talking as small as
这种小事
a little light bulb that’s broken in the cockpit,
那么这架飞机也哪儿都去不了
and the plane is going nowhere.
我自己就曾遇到过要换另一架飞机的情况
I personally had to switch to another plane
因为飞机在前趟飞行中遇到小鸟撞击
after encountering a bird strike
飞机引擎需要进行彻底检查
on the previous flight and the engine had to go through a thorough investigation.
想象180名乘客在30分钟内登上飞机又下去
Now picture 180 passangers boarding and deboarding in 30 minutes –
一脸尬笑[笑]
happy faces [laughes]
不过
But by the way,
我可以接受因为技术故障导致的延误
I’ll take any delay due to a technical failure,
难道你愿意开着轮胎松动的车上路吗?
or would you set off in your car with a loose tire?
第四大原因:机组人员迟到
Reason number 4: crew memberarriving late to the plane.
这种情况发生的概率很低 但是有时机组和乘客
It’s a rare case, but sometimesthe crew and passangers
不得不等待迟到的乘务员
have to wait for a missing crew member. Now,
不过 你可不要以为
don’t get the image
迟到的乘务员是因为睡懒觉
that the late crew member just had a lay-in
而上班迟到了
and arrives late to work.
通常情况下 该同事是临时调来代替
Most likely, the colleaguewas called out of stand-by
另一名临值机请病假的机组人员
as one of the other crew members called in sick just prior check-in.
大多数的待命任务要求
And most stand-by duties demand
你只有1小时的时间来准备
that you have one hour to get ready,
开车到机场 通过安检
drive to the airport, go through security,
来到已经延误的飞机上
and get taken to the NOW delayed plane.
所以你讽刺地鼓掌欢迎机组人员
So sarcastically applauding the crew member onto the plane
上飞机一点也不酷
isn’t cool at all,
因为他或她很可能冒着生命危险
as he or she most likely risked their life driving
疯了一样地在高速公路上飙车
like a maniac over the highway
只为为了各位而准时到达
to be there on time just for YOU.
所以不要那样做
So don’t do that.
第三大原因:迟到或消失的乘客
Reason number 3: the lateor vanished passanger.
机场的神秘事件之一就是
One of the airport’s TOTAL misteries –
一名乘客值了机 却没到达登机口
a checked in passanger who’sunable to find his boarding gate,
他的行李显然是被运上了飞机
his luggage obviouslymade it onto the plane,
但他人却不见踪影
but he has vanished somewhere inbetween.
他甚至得到了在机场广播中
He even gets the luxury of hearing his name
叫到自己名字的豪华待遇
being called out overthe terminal PA system. Now,
现在这名乘客 或至少是他的行李
as the passanger,or at least his luggage,
对飞机上其他乘客的安全造成了潜在的威胁
now creates a potential security threat to all other passangers onboard,
配载人员必须卸下所有的行李
the loading crew has to unload all pieces of baggage
只为找到他或她的手提箱
to find his or her suitcase.
很显然 这要花费很多时间
That will cost time, obviously,
就在找到行李的时候 他出现了
and just as the luggage is found, he shows up. Well,
我们通常不会让他的行李上飞机
we often set offthen without his luggage,
就想给他一个教训[笑]
just to teach him a lesson [laughs].
第二大原因:持续罢工
Reason number 2: going on strike!
如果你们生活在欧洲
If you live in Europe,
你们都会受到一个国家的影响
you’ve all been impacted by a country,
这个国家的空中交通管制员喜欢
which has air traffic controllers who just LOVE to go
罢工 一年至少一次
on strike at least once a year
扰乱整个欧洲领空
and disrupt the entire European airspace. Now,
就不说名字了
not to mention any names,
但他们把国家的座右铭太当真了
but they’re taking their country’s motto a little TOO serious.
他们的南方邻居也好不到哪里去
And their southerly neighboursaren’t any much better, so,
对不起伙计们
sorry guys,
你赚那么多钱 不应该罢工
but you make WAY too much money to go on strike! Now,
更糟的是 如果你乘坐航班的航空公司罢工了
even worse, if yourairline goes on strike,
将导致你滞留机场好几天 那真的太倒霉了
leaving you stuck at your departureairport for days [!] if you’re unlucky. Now,
在我为这个视频查阅资料时
during the research for this video,
我一点也不惊讶那家知名德国航空公司
I wasn’t surprised that famous German airline
是罢工记录的保持者
is the record holder in strike days. Well,
我是一名飞行员
I’m a pilot,
我的同事有足够的理由罢工
and my colleagues had good reason enough to go on strike,
这对他们来说是好事
so good for them.
特别是那家尾翼上
Especially the airline
有女士在弹竖琴图案的航空公司
with the lady playing the harp on their tailfin,
他们完全有理由罢工
they have every reason to go on strike,
相信我 干得好 伙计们
believe me, well done, boys. Also,
机场地勤一旦罢工会造成大面积航班延误
very effective in causing delaysare airport ground staff strikes.
机场总是宣传自己是安全避风港
Airports always promotethemselves as”safe havens”,
但是他们最先削减的就是安保人员的薪水
but the first thing they’ll cut is the salary of the security staff.
你愿意因为必须检查乘客的行李
Would you like to be shouted by passangers
而被客人大吼大叫
because you have to search their luggage,
却只拿最低的薪水吗?
but you’re only beingpayed at minimum wage?
我非常怀疑这点
I HIGHLY doubt that.
所以 帮我个忙
So please, do me a favour
遇到他们时请给予他们必要的尊重
and approach these people with the necessary respect
而不是抱怨他们的工作毫无必要
instead of complainingtheir job is useless.
导致飞机晚点第一大原因
And the number 1reason for delays
就是离场时间
are slots. Now,
我相信你可能听飞行员说过
I’m sure you mighthave heard a pilot say
-女士们先生们 非常抱歉地告诉你们
“Ladies and gentelmen, Iam very sorry to tell you,
我们刚接到一条离场时间通知
but we’ve just received a slot
我们预计在两小时内起飞
time which starts in two hours,
但我们想尽快出发
but we’re hoping to getreleased a little earlier,
所以我们发送了一条准备完毕的消息
as we’ve just sent a”ready” message.”
这些意味着什么
So what does all that mean?
想象一下由于道路施工四条车道缩减到一条
Picture a four-lane highway narrowed down to one lane due to roadworks. Now,
想象一下这个不幸的情况
okay, everyone pictures this,sad reality, unfortunately. Now,
我们把天空也比作四条车道的公路
let’s say the sky isalso a four-lane highway
而机场是只有一条车道的道路施工现场
and the airport is the roadworks with literally one lane to land on.
跟公路唯一不同的是
Now the only differenceto the highway example
机场的管控会优先考虑避免
is that the air traffic controllersin airports want to avoid
空中航道的拥堵而不是陆地上跑道的拥堵
congested traffic in the skyprior to that one lane runway.
因为没有飞机会消耗几个小时的燃料
Because no plane carrieshours and hours of fuel
在空中等待工作人员清理地面
to wait in the sky fortheir landing clearance. Now,
每一班机都需要严格执行飞行计划
every airliner hasto file a flight plan
注明他们的执飞高度
stating the flight level they want to fly,
飞机机型 飞行路线 等等
aircraft type, routing, etc.,
但更重要的是飞行时长和飞行速度
but more importantly, theflight time and speed. Now,
例如 欧洲的空中管制人员
the air traffic controllersat Eurocontrol, for example,
要确认在当天特定时间需要降落的航班数量
check how many planes approach an airport at a certain time
还要比对
of day, and compare that
机场能够承载的最大航班容量
to its maximum capacitythe airport can handle. But,
但不仅仅是机场 他们还需考虑
it’s not just the airport.They also have to consider
经过或待在管制区内的飞机数量
how many planes fly throughor within a control sector
以便减轻管控员工作负荷 因为如果管理员
to not overload the controller,because overloading a controller
负担过重 一次管理过多飞机
by giving him or her too many aircraft
是非常危险的
at once is just way too risky. Now,
所以管控员可能会把工作分成两部分
the controller MIGHTsplit it into two sectors
同时与另一个管控员一起工作
and share the work with another controller, but,
但如果工作还是超过了他们的控制范围
if that is gettingout of hand as well,
欧洲航空管制中心就会发出CTOT
Eurocontrol will sendout [a] so-called CTOT –
一个预计起飞时间
a calculated take-off time,
或多数人称之为“离场时间”
or better known as”slot times”. Now,
设置CTOT或管制起飞时间的目的是
the purpose of a CTOT, or a slot,
让管理员预测
gives the controller a future prediction
在某一确定时段内他的管辖区域
of how many planes he can expect
可以容纳多少架飞机
in his secter at a certain time
且指引飞机安全着陆在跑道上
and safely guide the planes onto that one lane,
或是使用仪表降落系统 避免让飞机在空中滞留
or ILS, without havingto put them into a holding.
所以我们列举的高速路例子可能是这样
So our highway examplewould then look like this:
你有广阔的空间
you have all the space,
但是你只能用一条跑道
but you’ll be using up only one lane,
当每辆车或每架飞机
as every car, or plane,
提前规划好出发或起飞时间
sets off at a predetermined take-off time,
交通就能更畅通
resulting in a smoother flow of traffic. Now,
有几种不同类型的离场时间
there are various types of slots.
最常见的是天气管制
Most common are the”weather” slots. Now,
比如说你在纽约肯尼迪国际机场
let’s say you’re sittingat New York JFK airport,
想飞往华盛顿特区
wanting to fly to Washington D.C.,
而巨大的雷暴云团正停留在华盛顿的上空
and a massive thunderstorm issitting over the White House. Now,
管控员很有可能会进行“天气”管制因为
the controller most likely willgive you a”weather” slot,’cause,
他已经知道暴风雨过去之前
why would he let youtake off already knowing
你将在华盛顿南方的某处滞留 这种情况下他怎么会让航班起飞呢
that you’ll be holding somewhere north of Washington before the thunderstorm clears?
同样地 机场能见度很低的情况下也会有管制
Same goes for aiports which have low visibility procedures in progress –
此时各项工作进展都非常缓慢 管控能力也会降低
everything works at a slower pace, and the handling capacity is much lower.
还有一种“流量管理”管控
Then there are”flow managment” slots. That,
据我所知
to my knowledge,
这意味着空中管控中心没有足够的管控员
means that air traffic controller hasn’t got enough controllers.
当我飞周末去往德国西部的航线时遇到过很多次这种情况
This happened to me numerous times on weekends flying into western parts of Germany. Now,
请记住
keep in mind:
每3秒就有一架飞机起飞
an aircraft is taking off
或是进入欧洲的空域
or entering European airspace every 3 seconds,
所以空中交通管理员需要时刻进行工作
so there is a constant need[of] air traffic controllers.
还有一种“机场”管控
Then there are”airport” slots.
例如 如果你飞往希腊的一个岛
If you fly to the islandsof Greece, for example,
一些机场只有2到3个停机点
some airports only havetwo 2 to 3 parking spots,
所以空中交通中心要协调你的离开和到达的时间
so air traffic coordinates yourdeparture and arrival time
这样你就无需在目的机场持续等待
that you don’t have towait at the destination airport
直到你航班的停机点空出来
until your parking slot clears.
作为一个飞行员
And as a pilot,
你可以预计管制时间 因为有时
you can anticipate its slot time because sometimes
你会被要求立即减速飞行
you get a clearance to drasticallyreduce your speed during cruise
然后你就知道
and then you know
你的目的地机场已经达到最大可承载量
that your destination airport is reaching its maximum capacity
或者正在经历一些变动
or is experiencing some discrepancies,
比如 为了除雪而关闭跑道
like runway closures due to snow removal
或者类似的情况
or of similar nature. Now,
飞行员还会说
the other word[s]the pilot mentioned are
“我们已经发出了准备就绪的信息”
“We’ve sent out a’ready message’.”
这意味着什么
So what does that mean? Now,
首先
first of all,
只有在乘客全部登机后
you would only hear a pilot say that
飞行员才会这么说 然后你开始等待
once all passangers are onboard,and then you wait and wait.
但为什么飞行员明知
But why does the pilot board all passangers
不能马上起飞
if he already knows
还要让所有乘客登机呢
that we’re not gonna be taking off any time soon? Well,
其实他并不知道在跑道被清空前
he doesn’t really know how long
具体还要等多久
he’s gon na be waiting for his start-up clearance
通过发送准备就绪的信息
because by sending out a”ready” message,he’s letting the controller know
是让管理员知道他和他的飞机
that he and his plane are
已经准备好在管制起飞时间前
ready to take off at ANY time
任何时间起飞 这意味着如情况有所好转
before the actual slot time, meaning ifthere is any improvement,
不管是天气方面还是交通方面
maybe in weather or overall traffic,
管理员都有可能联系飞行员
the controller would then contact the pilots
告知他们一个更早的起飞时间 他们会这样说
and give them an earlierdeparture time by saying
“AirJoe125号 航空管制取消 起飞请求批准
“AirJoe 125, slot has beencancelled, start-up approved,
准备在15分钟内起飞”
be airborne withing the next 15 minutes.” So,
因此 飞行员要求所有的乘客在飞机上等候
therefore, the pilots requestall passangers to be onboard,
因为在15分钟内让所有乘客登机
because there’s no way to board a plane
是不可能的
in under 15 minutes
因为有这样的乘客
with passangers like this:
所以 帮自己一个忙 请不要
So please, do yourself a favour, and DO N’T get furious
对乘务人员和飞行员发怒
with the cabin crew members or pilots –
相信我
trust me when I say they want to
他们和你一样想起飞
get airborne as much as you do,
但无论如何 乘客总是找到各种理由抱怨
but still passangers always find some reason to complain, one way or another.
如果延误了 他们抱怨如果飞机颠簸 他们抱怨
If they’re delayed, they complain,if it’s turbulent, they complain,
但飞行员和空中交通管理员实际上避免了
but the pilots and air trafficcontrollers are actually preventing them
他们在坏天气中濒临死亡
a”near-death” experience
但他们却毫不自知
with a”bad weather” slot doesn’tstrike their mind at all.
我在从业十年的经历里
And one thing I have learned of being
学到一件事
in this industry for over ten years now,
绝对 绝对不要低估天气的影响力
do never, ever underestimate the weather.
