On the L1011 we always have nose up pitch trim. This shows that th CoG is fwd of the CoP. It is good form to load the aircraft with as far back a CoG as possible thus ofloading the "STAB" (elevator for lesser mortals). This way you burn less fuel, make more money, are likely to remain employed for longer.
The only real restictions come at light weights because the stab doesnt go very far nose down and without the weight turning moment it could run out of authority if for eg. going around with the center engine out. all the pitching moment from the wing engines is nose up !!!!!!!!!
We do have weight related go around thrust settings to compensate for this.
