Thank you for the answers.
So generally, for an unpowered control system, in trim condition the elevator floats to a balance position and it is faired not with the rotated tailplane but with the local airflow, so that the force on the control column is relieved.
Is the misalignment relative to the adjustable horizontal stabilizer small?
I suppose that for maneuvering the stabilizer actuator is too slow and the elevator is used for this purpose, right?
