CG vs. fuel consumption
I know that the farther aft (closer to Centre of Pressure) CG moves, the less fuel is burnt because of less downforce req'd from the tailplane.
But is it (in theory) better to have the CG at CP, rather than aft of the CP? Would the trim- and induced drag of the tailplane outweigh the benefits of producing positive lift if CG is located beind CP?
Thanks!
