I was wondering how the engines that power the A340-500 and -600 compare with those on the B-777.
Is Rolls Royce the only engine manufacturer for the A345/A346, or will P&W and GE have engines available?
The A345 will have Trent 553-61's and the A346 will have Trent 556-61's. How are these different and how do they compare with the powerplants on the 777 in terms of thrust ratings, size, etc?
Looking at pics of the A346, the engines look big, but are they as big as the 777's?
