*~BB Dragon :我地阿sir話國泰唔入A380既其中一個原因係因為佢地個target customer同其他競爭對手(eg. SQ)唔同
備註: 阿sir之前係國泰做左>30年

另外國泰高層之前就經常放風話 A380 個載貨量唔夠多,
要知道其實國泰起每架客機上面都一樣有做 Cargo 生意 ~

其實間間都有，細到連四川航空個d一樣有forwarder用黎走貨

唔買a380可能係食油大...依家油價感高...加上a380成日都壞
之前澳航a380壞左引擎...維修費是(天文數字)
香港唔買係是保守的做法

吓?? A380每個pax除返開佢係全球耗油量最低嘅commercial aircraft
所以A380耗油量其實唔高
問題只係有無可能時時都打得爆架機姐
咁人少左，除返開你咪覺得條數多囉

呢個當然, 不過國泰呢間公司一向計得好盡,
佢入 777-300ER 都係因為載貨量高,
所以有陣時有 D 線眼見載客量唔多佢都照飛,
實情佢架機上面都載左唔小貨,
計黎計去佢都係有盈利 ~

所以未話每間航空公司取態唔同,
有航空公司鐘意一架機載哂 D 人去佢自己個 Hub 度再轉佢自己航空公司 o既其他線 (呢個好明顯係 EK)
都有航空公司鐘意做點對點或者以航班密度去爭客, 所以用中型客機 (前者如 NH, 後者例子 CX) ~


所以就要睇航空公司自己想點,
不過對於以密度取勝 o既航空公司黎講, 有時都要睇下人地比唔比到 slot 你, 如果唔係你開幾多班都係死 (尤其 LHR) ~
所以國泰到今時今日都仲有咁多 744 起手 ~

話哂有4引擊安全D

有4個引擎就安全啲？
得...你贏...

點解 4 個引擎唔會安全 D?

如果 2 引擎同 4 引擎一樣咁安全，就唔會有 ETOPS 呢樣野啦

其實 ETOPS 已經不斷放寬,
不過始終兩個引擎就係兩個引擎,
當其中一個引擎有事就要靠另外一個引擎,
而四個引擎出事都仲有三個引擎頂 ~

暫時黎講只係得部份南半球 (飛過南極上空) 航線始終要用 A340 或者 B747 / A380 等四引擎客機,
因為就算連 777 個 ETOPS 都未能達到要求 ~

其實etops係d乜，有乜用

aa67 :其實etops係d乜，有乜用

ETOPS 係咩,
呢度幫到你 ~

年年都加價，無錢賺就假

Jetfoil :年年都加價，無錢賺就假

今年都加唔小,
尤其係 Y 位轉左做 Y+ 之後, Y 位由本來已經唔多夠到而家直情全 FULL 要迫人上 Y+
呢下佢地已經搵多左唔小 ~

Consider the reliability of jet engines are providing today and you will get the answer why ETOPS was introduced in the 70s and nowadays almost all twinjets are ETOPS certified.

Aviation technologies changes every year, day and second froms 1903, the first powered aircraft flew to sky at Kittyhawk. One of the main reason that the industry introduced ETOPS is piston propeller engines were having poor reliability causing degraded operations must be taken like Lockheed Constellation are flying with 3 working engines all the time. The industry worries the same reliability problem will also applies on jets lead all engine out where twinjets have no backup engines.

Nowadays, engines are controlled by FADEC or even more advance electronic control system that installed on individual engines to manage their ignition and fuel distribution. These kind of advanced FADEC could usually be seen GE engines. Although at most of the time they are working as designed way and helped the airline to use lesser fuel and extend maint. cycle of spark or something related to combustion or pressurization components, they are very sensitive while flying into severe turbulence or sudden-change weather condition. Engine flameout will happen easily with frequent-changing temp plus idled engine like approach phase. This is due to weather condition and air density changes are confusing the FADEC sensor and chips. Also it's driver would contained bugs may lead to such a flameout as a fail-safety concern. There were numbers of flameout over the ocean of GE CF6-80E2 which is one of the engine option of Airbus A330. Investigates shown that too-sensitive FADEC caused is the major and only clause. How about adding 2 extra engines like A340? You will get 4 out at the same time and your workload in cockpit is double although you will nothing besides light switching and lack of bleed air as a passenger.

Furthermore, volcano ashes are one of the major hazard and cause of FOD to jet engine. Thick ashes could jam engine ducts stuck and strike with baldes. Your engine will definitely damaged by it whatever you have a advanced GE90 or conventional PW JT8D engines. Do you think you can avoid the case by having 2 extra engines?

With these clause above, I don't agree the point "4 engines is safer" and "4 engines would provide quad reliability".
以師奶智慧嚟講，多幾個熱水煲，實穩陣嫁。但依家係電腦時代呢

油價太高，客量唔夠

GY7155 :油價太高，客量唔夠

客量夠就夠

不過相比開兩部777, 747, 350，開得密d，對乘客方便d ~

其實睇下 SQ 入左 A380 之後 o既業績變成點就知咩事
