I just know about the 787 and from what I have heard it is going excellent. Its pretty neat how they test those on the 747 as well. I did hear a few weeks ago there was a problem where the engine scrapped the ground. I don't know if it has been confirmed yet.
All of the opinions stated above are mine and do not represent Airliners.net or my employer unless otherwise stated.

Aren't both 787 engines certified at this point? RR first, GE second? Doesn't mean they aren't working to improve them, but they were certified and ready for EIS, but EIS sort of got delayed. Just a little bit…
Of all the things to worry about... the Wookie has no pants.

Quoting Transpac787 (Reply 3): Wasn't there an article some time back that RR missed it's fuel burn targets rather substantially on the Trent 1000's, and they're having to work to resolve it??
I have no links to back this up, but this is the last I have heard:
RR is better on SFC than GE on take-off and climbing to cruise altitude. GE is better on SFC while in cruise. So the longer the flight, the advantage should shift towards GE at this time. But no doubt RR and GE are working very hard to improve their engines on the supposedly "weaker" parts of their performance. Both are excellent products as far as I can be a judge of that. But I am not an expert on this, not at all.

Quoting Cloudy (Thread starter): How are the next generation of engines doing - the ones used to power the 787 and A350? That seems to me to be a huge factor in the success of these programs, but not often talked about.
Both certified. You could strap one to a 787 or A350 and fly it tomorrow, if only you had the rest of the 787 or A350.

Exactly. Both RR and GE are now committing to rolling some additional improvements into the EIS engines that, under the original schedule, wouldn't have shown up until a few years after.
