因為atc試過幾次都係衰personality
唔想考cadet都係咁


我覺得你要諗吓自己係唔係有問題喎
因為無論atc定pilot都係乜人都有,無理由肥
你係唔係估人地想要咩答案?


唔係㗎,嗰陣去ob,個instructor 同我哋講,話國泰都幾犀利,我哋成班各有不同,有人淆底-我,有人大膽,但個core personality 差不多一樣

巴把可唔可以講多啲 core personality 點樣一樣

我都唔知,嗰順instructor 都無講

我嘅認知係,飛機師唔需要某一樣嘢好叻,平平均均就得。要有臨危不亂,去到最後關頭要有少少犧牲自己而救其他人嘅傾向。

我自己平時都係好容易緊張嘅人,但有嘢發生我反面好平淡應對。有次喺德國炒車衝出公路架車失控,個駄已經鎖實,但我都係不自覺咁將個駄狂chok等佢轉多少少,最後我停到個位同個架空電纜塔差一米唔夠,過多少少我就回唔到你。之後坐我側邊個fd平靜咗之後話見我平時癲癲傻傻on99,但都總算明白點解公司會揀我

平時做sim 啲emergency 係咪都會好緊張

你明知假嘅有乜好緊張?

我想問下lift production 方面既野 各位巴打
是咁的,我睇緊FAA 本書
佢有Part 寫到好1999.....
bernoulli effect 講左 當air 個velocity 高既話, 空氣之間的壓力就會下降
但FAA 把書有part 寫到好1999
佢剩係話 air 當經upper surface area 個陣,air速度會加快..壓力會下降...
但問題 本野無寫到 點解air 經過upper surface area 個陣 速度會加快
係因為upper surface area 細過 lower surface area 定係其他原因?

2. Upper surface 應該長過Lower surface 喎

因為upper surface係curved 因為相同距離下要行較多,所以上面空氣行快過下面

應該係symmetric都一樣?
因為隻機翼係有個angle upward
而below wing既flow surface大過above wing
by lift coefficient,
當flow area越大, average flow speed就會下降?
唔知岩定錯

假設air density, lifting force, lifting coefficient 不變

你assume 左lift is equal wo
我理解係A decreased => lift force decrease

人地講緊話根本唔會meet up at trailing edge 唔關距離事,個theory 係任何情況都唔成立

同埋lift equation係成隻airfoil咁睇 唔係拆開上下咁睇 v係true airspeed of the airfoil 唔關upper and lower surface airstream 事

求其他大師指教下

其實應該係wing curvature create pressure difference create lift, velocity difference 只不過係因為有 pressure difference而產生既
2017-08-18 20:25:21

就係最後個part 點解有aoa 就upper 快過lower

因為有vortex 做咗個circulatory flow 所以上面嘅velocity 會快啲,求fatso 大神指教

睇過好多lift theories
但全部都離唔開pressure difference依樣嘢
至於點解有個difference就係唔同theories嘅分野

我自己理解就係
airflow係circular motion嘅一種,
circular motion就一定要有向心力令air貼住wing surface
依個向心力就係pressure gradient (P1>P2>P3)製造出嚟



有個定律就係:喺一個circular motion入面,越近centre of curvature嘅streamline,pressure就越低 (P1>P2>P3)
加上我哋都知air flows from high pressure to low pressure region
由此推斷,越近wing surface,air pressure 就越低

亦即係話,喺upper wing surface:
pressure drops from atmospheric level (Patm) to Pus (最近upper wing surface嘅 airstream嘅pressure)

喺lower wing surface
pressure drops from 最近lower wing surface嘅 airstream嘅pressure (方便解釋,assume佢叫Pls) to atmospheric level (Patm)

Pls>Patm WHILE Patm>Pus
所以Pls>Pus
依個就係係我哋所知嘅difference in pressure between upper and lower wing surface

唔該晒巴打解釋先 但其實巴打,有無可能唔報flight course (YAA DACP etc...) 唔去Trial flight.... 剩係靠自修讀書入到cadet....

其實好多入到既都只係識基本野
唔好諗到要識得好多先考到
面試係睇你個人唔係問答比賽鬥高分鬥參加得多野
飛都無飛過都有人入到啦

Final都係問基本

你與參加多野 飛得多咪問深d
