A quick question regarding the NEO’s fuel efficiency. I can see that in the app it says Fuel burn 4.6t per hour for both the CEO and the NEO version. My understanding is that NEO has higher MTOW and higher Zero Fuel Weight as well, so maybe its not that simple to compare the two engine option’s efficiency.
On the RR website I read this: “The Trent 7000 […] features a 10% specific fuel consumption improvement thanks to its small, high pressure-ratio core and the latest, fully swept, wide-chord fan technology.”
But how is the engine more fuel efficient if the fuel flow is exactly he same in the sim? I did a quick test flight, and with the same conditions, same weather, same route, flight level, speed weight etc. they had the same FF value. Where is the 10% fuel consumption advantage? Is there a difference between the two planes in the sim?
