The flight dynamics (FD) are slightly off according to the Boeing FCOM. Your model is somewhat overpowered in the CLB phase. I have attached a table comparing your model with that of the FCOM.
This is with a TOW of 220 000lb / 100 000kg, no weather, standard temperature and pressure from sea level.
The cruise pitch is also somewhat off. At 100t at FL350 (M0.78) the pitch should be +3 degrees - yours is somewhat lower.
The N1 values at CRZ are also off. According to the FCOM, in the above mentioned situation, N1 value should be 79%. The CS model's value is 75%.
Captain Sim has done a great job on the 757/767 so it would be really appreciated if you could please fine tune the flight dynamics.
I have not looked at the RR dynamics yet - will do later.
Thanks again for your on-going efforts to perfect and update these two airplanes.
