Difference between RR and GE engines?

[JJPrum]

In the view of airlines, what are the differences between them?

What makes them use GE or RR for their B777?

:) thanks!



Note: I know there are a lot of answers on google, but couldn't find a good one with tech or airline view. Hope u guys can help:)

Depends on which engine manufacture takes the airline engineering/operations director to the nicest restaurant and gentleman's club.

Not that I'm cynical.

Rolls Royce engines are the bee's knees, the dog's bollocks, as they say.

Rolls Royce engines are more powerful, more efficient, and last much longer. What do you expect? They're made by the hands of British engineers.

But the many benefits come at a higher price.

As a Brit who is not a bell-end, I apologise for the fact that some of us are.

The 777-300ER/200LR are only available with the GE90 engine. In fact, for all practical purposes, the Trent 777 is out of production - Boeing hasn't delivered a Trent powered 777 in years. That's unlikely to change in the future, and the Trent isn't even an offering on the 777X.


As for SkiingPilot, the GE90 on the 777-300ER is currently rated at ~115,000 lbs. thrust. Please tell me which Rolls engine is currently rated at over 100,000 lbs. of thrust?:eek:

That GE90 didn't look too healthy in Las Vegas earlier on.
