I was making the point that 4 of the 5 largest operators of the 757 use PW engines. I agree that more 75's are powered by RR than PW, but I don't think it's close to the 80% that you mentioned. I think UA's 777 are GE powered and unless NW has RR's on their A330's, I don't think they are a Rolls Royce customer either :confused: AA is the worlds largest 757 operator and they use the Rolls RB211. RR powers the "vast" majority of 757's and PW doesn't even come close. The RB211 incorporated the RR 3 spool technology and wide chord fan making it a superior engine. UA has PW on their B777's but PW's market share on the 777 lags behind GE and Rolls. However, UA is a big RR customer. They have the largest IAE V2500 A320 fleet in the world just ahead of Jetblue. NWA is also a RR customer. Their B787 will be powered by the Rolls Trent 1000. The vast majority of Airlines around the world are RR customers and that includes "all" the legacy carriers in the US. And as you might put it................NICE TRY!!!!!!! AL |

hey this might have already been discussed but a buddy of mine said that he had a fedex guy tell his captain that the 757's that fedex is getting are the ones delta has right now.. Is that true?.....
This may be true. According to DAL's page on APC, they're looking to simplify their fleet to four a/c type. Which one's they are....I don't know. atp |
Wow ...

Me. 12,000 hours flying the Pratts with no problems.
:D I have flown both ... and agree with the characteristic differences stated by most posters. But without spending hours on the web looking over charts and graphs, I'll say this much ... most maintenance reliability types prefer the RR for its reliability ... I also think it is why UPS switched to the RR in the middle of its fleet, but anyone on here with more time at UPS would know for sure. Everything that we can point out as differences as pilots is just that ... differences. Airlines worry about cost to operate and maintain and reliability ... in no particular order ! Later, CC |

There appears to be some confusion here.

AL 1049 757s produced, 617 RR and 432 PW , 59/41% IAE is a partnership between four companies PW,RR,MTU,Japanese aircraft. As of July 07' Delta is the largest operator of 757s. Delta is an operator of RR engines, eight AC with no more RR orders in sight. From another thread... Delta is not getting rid of 757s for fleet simplification. The lease holder wanted them back. |
There's a lot of exciting things going on at GE and RR right now with the next generation engines.
Also, the next generation aircraft from Airbus and Boeing are very exciting. We are fortunate to have such great technology in our time. AL |

Some info from Boeing, AMR, DAL, IAE websites...
As of July 07' Delta is the largest operator of 757s. Delta is an operator of RR engines, eight AC with no more RR orders in sight. The following quote is directly from DL's website. Pratt & Whitney signed a 10-year exclusive deal with Delta TechOps in which they will provide TechOps with materials for the PW2000 engine type. Delta was the launch commercial customer for the PW2000 engine and over the years TechOps has developed significant repair capabilities on this engine. “Delta Air Lines operates the largest PW2000-powered Boeing 757 fleet in the world,” said Jim Keenan, senior vice president and general manager, Pratt & Whitney Global Service Partners. “We are proud to be Delta’s strategic partner and exclusive source of PW2000 material.” source: http://http://news.delta.com/article...ticle_id=10649:cool: |

No. Delta operates PW powered 757s. Where did you see on DL's website that they operate RR powered 757s? :confused:

I blame the public education system for my reading comprehension! :p

Rolls Royce has really turned things around in the last 20 years with the RB 211. It was a real problem laiden power plant. On one of my trips across the pond, the RR CEO came up to the cockpit for a visit (oh, the good old days!) He asked me what I thought of the RB 211. I told him that I had no problems with it. He replied, only half jokingly "If I type up your statement, would you be willing to sign it?" Later I had big problems with one..scattering fan blades over the southern half of New Mexico.
