First of all I want to encourage everybody not to put biased opionios into this thread (because very often such topics lead to a RR vs. GE duel, so try to be objective)
Well my question is very simple. Is there a (significant) fuel burn difference between the GP7200 and the trent 900?
If so (well EA claims to be more efficient) how big is this differenvce and what does this mean for the operating envelope (I could read that the trent 900 has a weight advantage so maybe on shorter missions <5000nm the trent 900 would compensate for this disadvantage). Maybe anyone has also got some data about the noise emissions.
