"However, GENERALLY (not always) Rolls are
considered more reliable than either Pratt and Whitney or GE. However,
all three manufacturers make good engines. "
Not true at all. For years Rolls-Royce engines were the least reliable engines. In fact the first engine they ever made that was really superior in reliablity to another was the RB211-535. And the only reason the -535 was really superior is because PW took their time fixing some major teething problems that PW2000 had.
The 94 inch engines (CF6, PW4000) have an inflight shutdown rate twice as good as the Rb211.
There have only been two times that Rolls-Royce has produced a more reliable engine. 1. The Rb211-535 was more reliable than the PW2000. However, PW has since fixed the problems and the engines now enjoy virtually equal ratings.
2. The Trent 800- the trent 800 has marginally better reliability figures than the PW. The GE90 is a distant third.
