Jet Engines
Hi all,
got a few questions about Jet Engines.
In CX (or any airline), one aircraft type may use different jet engines. Like 747-400 use PW4062, GE CF6 or RR RB211-524.
how does the airline choose the engines, like more power, more efficient or sth else.
as i know, PW and GE bulid 2-spools engine, while RR build 3-spools engine.
so if you are asked, what are the advantages of each engine, what would be the answer. is there a general pros and cons for each engine manufacturer. how would you compare the engines
Looking for your reply
