Unfortunately I am not a pilot and this is my first post on this tragedy, but from my limited understanding of the trim function, it is to take the load of the control column or stick to reduce or maintain a balanced feel with no loads felt.
Obviously in the Airbus with the stick having no feedback on control surface loads, I therefore assume the trim is there to reduce hydro-mechanical /electro mechanical loads on the actuation systems during ascent, descent and level flight modes. If this is the case how would the pilot manual trim in alternate law?
What would be his indications to make the corrections? Why with the stick back would auto trim go to fully max with such a low horizontal speed (i.e. elevator control surface loading would have been at a minimum if the aircraft was at or below stall speed , does vertical speed have an influence here?)
