不小心的英文-高中成语大全

几经周折,我联系上了新加坡ATC的Deputy Chief,他的回答是:Reference to your query on
NPDC for flights operating in the South China Sea area, you may wish to refer to Singapore AIP
under ENR 1.18-19.



However we would also like to take this opportunity to respond to your query.



NPDC was first practiced in the late 1990’s to reduce the delay for flights departing from South
East Asian airports. This is to reduce the coordination between ATC Centres for clearance and an
aircraft can start up for departure without Singapore ATC coordinating with downstream ATC
centres for levels.



When Singapore Delivery give clearance for ‘No PDC FL350’, it means that there is no delay for
you. Sometimes there may be another aircraft that has already been given the level requested and
you would have encountered being given two or three levels to choose for no delay if the level you
requested has been given to another aircraft already.



When you are airborne, ATC will then coordinated with the next ATC Centre for FL350 subject to
traffic. If it is approved by the next ATC centre, you will be informed by the enroute controllers.
However if your requested flight level is not available, ATC will try to offer you the next best
level based on your request.





关于你询问的关于在南中国海区域运行的航班NPDC的问题,您不妨参考下新加坡AIP的ENR 1.18-19中的
相关章节。


但是,我们也想借此机会回应你的查询。


NPDC于90年代后期首次开始实 施,以减少对从东南亚机场起飞的航班延误。这是为了减少在放行时空管
指挥中心的协调,和让一架飞机 可以在新加坡的空管没有和下游航管中心协调高度的情况下就启动发动机。






当新加坡放行发布一个许可是没有PDC的FL35 0,这意味着你不会遇到延误。有时候你可能遇到这种情
况,当你请求的高度层已经被另一架在你前面申 请的飞机占据了时,则会提供2到3个其他的高度层供你选
择以避免延误。

< br>当你离地后,管制员这时会与下游的空管中心协调FL350的高度层。如果下一个空管中心批准,航路的 管
制员将会通知你。如果确实遇到你所要求的飞行高度是无法使用的,航管单位将尽力为您提供能满足您 要
求的其他次佳高度层。

no predeparture coordination很简单,就是新加坡给你的巡 航高度层,未与周边国家管制协调,
所以你实际上有可能因为其他周边管制区飞机的影响,飞不到这个巡 航高度层。 其实我们




是在国内飞麻木了,从来都是飞不到放行许可给你的巡航高度。 在某些国家和地区,放行
都比较较真。 Jeppesen 或者Area ATc 关于新加坡部分都有描述

楼上说的很对,我们在国内都飞习惯了,放行席位说的“巡航高 度”10次就有9次飞不上去。
机组基本都是应付说“收到”,都知道真正的巡航高度只有上天区调给多 高就是多高,基本没
得选择!
哪像国外,基本都是按照放行席位给的巡航高度飞!

NO PDC的意思就是说他现在给你的predeparture clearance并 不是一个绝对可信赖的许可,
也就是说实际情况可能会有变化,特别是巡航高度层是极为不确定的因素. 因为好久不飞新加
坡了,我印象中他们给PDC的格式应该是这样的PDC LEVEL
XXX,CLEARED TO XXX VIA XXX.....也就是说这个是专门针对他给你的巡航高
度而言的.
出师表
两汉:诸葛亮

先帝创业未半而中道崩殂,今天下三分,益州疲弊,此诚危急存亡 之秋也。然侍卫之臣
不懈于内,忠志之士忘身于外者,盖追先帝之殊遇,欲报之于陛下也。诚宜开张圣听 ,以光
先帝遗德,恢弘志士之气,不宜妄自菲薄,引喻失义,以塞忠谏之路也。
宫中府中 ,俱为一体;陟罚臧否,不宜异同。若有作奸犯科及为忠善者,宜付有司论其
刑赏,以昭陛下平明之理; 不宜偏私,使内外异法也。
侍中、侍郎郭攸之、费祎、董允等,此皆良实,志虑忠纯,是以先帝简 拔以遗陛下:愚
以为宫中之事,事无大小,悉以咨之,然后施行,必能裨补阙漏,有所广益。
将军向宠,性行淑均,晓畅军事,试用于昔日,先帝称之曰“能”,是以众议举宠为督:
愚以为营中之事 ,悉以咨之,必能使行阵和睦,优劣得所。
亲贤臣,远小人,此先汉所以兴隆也;亲小人,远 贤臣,此后汉所以倾颓也。先帝在时,
每与臣论此事,未尝不叹息痛恨于桓、灵也。侍中、尚书、长史、 参军,此悉贞良死节之臣,
愿陛下亲之、信之,则汉室之隆,可计日而待也。
臣本布衣, 躬耕于南阳,苟全性命于乱世,不求闻达于诸侯。先帝不以臣卑鄙,猥自枉
屈,三顾臣于草庐之中,咨臣 以当世之事,由是感激,遂许先帝以驱驰。后值倾覆,受任于
败军之际,奉命于危难之间,尔来二十有一 年矣。
先帝知臣谨慎,故临崩寄臣以大事也。受命以来,夙夜忧叹,恐托付不效,以伤先帝之明;故五月渡泸,深入不毛。今南方已定,兵甲已足,当奖率三军,北定中原,庶竭驽钝,




攘除奸凶,兴复汉室,还于旧都。此臣所以报先帝而忠 陛下之职分也。至于斟酌损益,进尽
忠言,则攸之、祎、允之任也。
愿陛下托臣以讨贼兴 复之效,不效,则治臣之罪,以告先帝之灵。若无兴德之言,则责
攸之、祎、允等之慢,以彰其咎;陛下 亦宜自谋,以咨诹善道,察纳雅言,深追先帝遗诏。
臣不胜受恩感激。
今当远离,临表涕零,不知所言。
