THE REASON WE TRIM IS TO NOT ONLY RELIEVE LOADS ON THE CONTROL COLUMN BUT TO SET THE REQUIRED AOA(I.E WE SEE ATTITUDE) WE NEED.
Trim is
not to set either AOA nor attitude (which are not the same). The reason we trim is to relieve loads on the control column. That was my point.
Except of course if you lose all your flight controls and all you have left is trim and engine power! Have a look at this incident
