Some more interesting figures from the 787 sim at LRC, FL370, ISA, 200T:
N1 86%
FF 2700kg/hr (x2) = 5,400kg = 11,900lbs
Weight 440,873lbs
Total Thrust 21,900lbs
Therefore L/D=20/1
Thanks Sidestick and Gearlever for your input. Very interesting.
Yes, it makes sense to reference AoA to the whole aircraft and not just the wing.
