Can confirm that sim training just taught me to look at each of the three trims (Rudder/Aileron/Pitch). The Call is 0 / 0 / 6 meaning the mid points of each setting.
Others I know have also been taught that at light weights trim the elevator to be more nose down which makes sense.
I do remember that it was said in class that apparently, prior to this accident the only flight manual that had the table to calculate a pitch trim position was the UK one, where the good ole CAA were alone in insisting on it prior to certification..............
