Please give your reasons.

I don't think there is one best. They all make equally good, successful, and high quality engines.

Unfortunately this is an undiscussable topic. Nobody here is really qualified to give a business answer.

We can hear from mechanics about which is easiest to fix, and from pilots on which they prefer.

But its hard to decide a "best".

There are no best.

Every airline has its own perspective and preferences in order to maintain the correct economic standars through equality and adaption of the engine to the carrier's network.

If there eventually were a best, it would be very subjective.

Dunno, seems like Pratt is falling behind the other two, just barely hanging on (relative failure of 409x on 777, having to team up w/ GE on GP7200, probably will be GE vs. RR for 7E7, PW6000 project, etc.). Almost seems they're not too serious about the commercial engine market :-(

I will agree with the previous poster, seems that PW is falling behind.

In addition to the things mentioned, the FAA has prodded PW to make improvements to the 40xx series due to a higher rate of IFSD than other engines in the same thrust class. And we all know about the well publicised initial failure of the PW6000. Time will tell if they are able to fix the 6000.

they all turn and burn... all are certified to the same standards all turn fuel into power and heat... the JT-8D was a true workhorse u could have a compresser stall and keep on rolling with them, The rolls royce tay had its issues... The RB-211 had its problems... I think if you look at the statistics which would be the only immpartial thing, CFM has the best numbers for on wing time... lowest IFSDs and the best dispatch relaiblity. Plus its the #1 selling engine right now... So based on that i would say CFM makes the and i hate to use the word "best"

Wilcharl,

I agree with your opinion. I already ponted out in a similar thread in the Tech/Ops forum, that ther is NO "best" engine. There is just the "best" engine for a certain mission profile and operation environment, nothing more, nothing less in my opinion. But there are many parameters influencing this environment, like fleet usage, usage of take-off derates, fleet commonality (maintenance) and so on to take into consideration.

Regarding your statements concerning the CFM engine, I would like to add some comments (as it is my daily job to handle them in our shop). There are examples where CFM engines reached high amounts of on-wing time. Nevertheless, the CFM56-5C4 variant that powers the A340-300 is known to cause a lot of headache for the short on-wing time you can achieve usually. The parameters like IFSD and dispatch reliability are also widely varying between the different operators and engine models. What I just want to point out is, that also those CFM56 have a lot of technical issues that causes the maintenance and operation personnels a considerable amount of headache.

Cheers, Thomas

As far as a personal favorite engine i prefer the RR RB211 that is on the L1011/757. As far a 777 Engine the RR Trent 90 is an awesome engine. And then of course there is the BR715 that is on the 717. I guess I am just a fan of the RR variants.

Its hard to say, they all make good engines, some are better suited for a certain type of aircraft than others. Maybe if you asked who made the best engine for a certain type of aircraft, this could be answered.

Personally I love how the RR engines sound on 757s.

Well, I agree with the people that say that there is no "best". I'm sure there are people in this forum that would like one engine more than another just because it sounds better when it's wound up for takeoff or because it produces more power than a different brand on a same aircraft. I'm one of those people Big grin

Let me ask this: Which engine manufacturer has sold the most engines overall. I'm going to guess and say Pratt... Including all those JT8Ds they slapped on the DC9s, 727s and 732s way back when..

 Big thumbs up

Dont forget all of the engines Pratt supplied to military aircraft. I believe GE also has put many an engine on military aircraft.

GE has put many an engine on almost all types of aircraft. Everything from CRJ's to 777's to Military and more.

I assume you mean RR Trent800... as opposed to GE90 (by far the superior engine for the highest MTOW 777s  Big grin)

I've never piloted an aircraft equipped with any of those...I dont see how I or anyone in a similar position can possibly answer that accurately.

Lycoming makes the only engine I have ever used myself. I'll take any of the big three as long as they stay attached to the wing.
