The Biggest is GE, Then PW, then RR. The GE is the best looking! Big thumbs up Then RR! Smokin cool

You Took A GE 777? Lucky Duck!

Oh, yeah, I know how you know. You were in HKG and saw a CO 777 right? Wink/being sarcastic

I took a RR Trent 892 powered Delta 777-200ER last year from MCO to ATL and I was amazed by the power on takeoff and how quiet it was!

Can anyone describe the small visual differences between these engines that help you be able to distinguish them?

If you look at the GE and the RR engines head on, you'll see three major differences.

1) The GEs are noticeably bigger.

2) The RRs are not perfectly round, whereas the GEs are pretty much a perfect circle.

3) If you look at the center of the engine, you'll notice that in addition to the swirly white line that is on both, there are dots around the the swirly line on the RRs, but not on the GEs.

PW I'm not as good at identifying.

Having flown on 777s with both GEs and RRs, I can't say that I have a definite favorite in terms of sound or power. Both are impressive. However, I think I like the look of the GEs better overall. They're so huge, it's incredible.

Actually, as for the PWs, they can pretty much be distinguished by looking at the center as well. The swirly white line that is customarily in that area is not swirly, but a straight line instead.

Excellent points Bombayhog, where did you happen to learn all this?!?!

As for the "swirly lines"- I know of them as "spinners" not that "spinner" is really a better term.

All the Best. Go RR.

Did you guys know that each of these engines puts out more thrust that an Atlas Rocket..the rocket that was used on the Mercury Space Program?

Wow.

If you look at the engines from the front, you can see that the GE90 and PW4000 fans both spin counterclockwise while the RR Trent spins clockwise. You can also identy the GE90 by the titanium leading edges on the composite fan blades.

The GE engines look better because of their size.

The Rolls Royce Trent 800 and P&W 4000 series engines on the 777 are much lighter than the GE90.

I think the P&W looks best, followed by the RB211
although I prefer the RB211 operationally.

The GE-90 looks too big, out of proportion to the aircraft.

Interesting how both AA and Delta are so impressed with
the RB211 they ordered a foreign engine on their aircraft.
The best contribution to safety is a competent Pilot.

Max Q, the Rolls Royce RB211 engine is on AA's 757-200s and was on Delta's L-1011s. On their 777-200ERs, they went with the Rolls Royce Trent 800 series engine.

For 777s I prefer :

1- P&W
2- GE
3- RR

RR 777 engines are exclusively of the Trent 800 variety. The RB211s are the RRs that you might find on the 744 or the 757. That is one beautiful engine. Not astoundingly huge or anything, but if I had to choose the most elegant engine, it would have to be the RB211-524H.

I have never flown in a GE powered B77 as much as I wanted to, but loooking at them rotating in front of you the sound is really fantastic! I've only been on PW and RR.

I've never been on a 777.

I would have to go with the PW, followed by the RR and then the GE.

Did you guys know that each of these engines puts out more thrust that an Atlas Rocket..

The Atlas Rocket as used in the Mercury program produced 360,000 pounds of thrust, which is 3x the thrust of any 777 engine. After leaving the atmosphere and jettisoning two of its three chambers, the engine produced 60,000 lbs. That figure is below the static thrust of a 777 engine, but the latter can't produce net positive thrust in the Atlas' operating conditions.

My dad chose ANA since it was cheaper to get to Shanghai. Well, took a B742 to Osaka for a transit then the B777 onto Shanghai. I was lucky, got to fly in a plane I like a lot, got to try a B777 for the first time and it was cheap for my dad. Why not?

Well, if I have to fly direct, I got a choice of China Eastern and Singapore Airlines. Well, he chose ANA, the time was better for us and it was cheaper than China Eastern by a bit too!
