So with the update 1.0.1 it got even worse. I gained fuel on a 7 hours flight of over 11 tons compared to the Simbrief plan! Yes I use the Ini Simbrief profile and I use the RR engine variant. Before the update, it was inconsistent. In climb I used about 1.5 tons more, but in cruise the fuel came back and depending on the flighttime I mostly gained fuel. On short hops it remained as a loss. But with the update everything seems out of bounds. I had a gain of 1,4 tons between waypoints with less than 200 NM. Very strange. Looking forward to a solution soon! Despite of that, this aircraft is a masterpiece! Congratulations! Keep up your great work!
