Have to agree and disagree with arcniz on this.
As far as my feeble memory can recall the tailplane/stab is always acting upside down. IE it is always pulling the nose UP not Down, (in a conventional stable non-flybywire a/c).
Also large airliners have adjustable/variable incidence stabs so the issue of pointing the a/c in the right attitude just to get the stab in line with airflow is a bit of a nonsense, sorry.
However, an engineer instructer once told me that the reason airliners fly slightly nose up is because the fuselage actually adds to the total a/c lift. On that we can agree.
Hope this helps
