This is why an airliner's fuselage looks perfectly horizontal (because it actually flies near 0 AoA) during cruise,
I'm neither an aerodynamicist nor a structural engineer but all the airliners that I have flown seem to cruise with the nose about 3 degrees above the horizon.
By 'horizon', I mean a reference that equates to a level attitude, not the visible horizon which at typical cruising altitudes is depressed by about 3 degrees below the true 'horizontal' due to the curvature of the earth.
If I am right, that would imply that the wings are actually mounted at close to zero angle of incidence. Can any structural engineer or test pilot shed some light?
