C:「H我看她身價如果沒有兩億的話,是嫁不去的…」

親愛的學長在他跟我交接之後, 隔天跟我提到, 資深教官/協調員認為我離場的一架飛機, 之所以沒有爬的那麼快, 都是因為我 cancal 他的 speed restriction... 以下是一些 MSN 的對話:

Q: ALL, I mean, ALL the pilots I asked, tell me that, cancel speed 250knots restriction will make planes climb FASTER. but ALL SENIOR ATC, tell me that it's gonna make planes climb SLOWER. I am totally confused, HELP ME PLZ.

Captain Wang 說: IT'S A FXXKING COMPLICATED QUESTION.. LET'S START FROM ....Vx and Vy
Q: just tell me the answer plz
Captain Wang 說: YOU ARE RIGHT THEY ARE WRONG to sum up....the airplane want to fly fast...then she can gains the best millage for certain fuel...best fuel millage.

Snohomish 說:因為要先低頭加速 一旦加到高速 會爬很快
Q: 教官 我這樣說好了 一萬以下會爬的比較快還是慢?
Snohomish 說:快

半年前的另外一個問題:

Q:Cancel speed restriction of 250knots, will it affect NADP1 or 2 procedure? In another way: high speed climb, is it more noisy?

CPA B777 Colin - Anchorage was nice! 說: Well, normally regardless of the speed we fly, the engine thrust is the same after takeoff, so the noise at the engine is the same. Over 250kts allows us to climb higher so I guess for people on the ground it is quieter.

CPA B777 Colin - Anchorage was nice! 說: At least in the 744 and 777 at CX. We have a climb thrust setting..... same setting regardless of speed

你得答案了嗎? 那完全是因為atc與pilot站在不同的角度思考問題所致. 取消250速限後, pilot在單位時間內的爬升率其實沒有太大變化, 但是對atc來說同樣距離內的高度的增加變少了. 對於要在有限距離內高度對衝, 可能會產生一些風險, 不過我覺得提早告知航情, pilot應可配合吧!
