Hello, I really like flying the IXEG. But I have a question about the trim in cruising. When I fly on FL370, I have always raised the nose of the aircraft 5 °. I presumably have an immensely high fuel mileage. (600nm 9.5 to fuel) In the external view, the plane (the windows) is never straight, but always tilted backwards. Flaps are all retracted, Airbrakes are retracted and I fly over the FMC. Do I have to possibly something in the FMC enter something? But my display shows CRZ mode after CLB mode. Or is it something completely different? Thank you in advance for your answers! Manuel
