Ok, wings generate lift most efficiently when they are at a 4 degree angle to the airflow (angle of attack).
The wing is attatched to the fuselage at about 2 degrees (angle of incidence).
Therefore the fuselage will be tilted nose up by 2 degrees.
Why they dont just make the angle of incidence 4 degrees and have a level fuselage I dont know, but I'm sure there is a reeason!
