To offload pressure on the primary flight surfaces, exactly the same as autotrim does. Autotrim is a way of solving the problem of not having the surfaces transmit the pressure through the primary flight controls - nothing more, nothing less.
"When does the pilot command trim ?"
You don't answer the question .. you just explain what is trim
With autotrim the pilot not command directly the trim
The position of the trim is a result of a combination of the elevators position and other factors
He have no power over the trim movements unless he switch to manual trim
