Clandestiono: the sidestick is not directly connected by cables to the ailerons, so has it not occurred to you that the ELACS still control the ailerons and you may not have full knowledge of how the ELACS have been programmed or how the stick deflection/aileron displacement ratio is altered by Flap Lever position.
Indeed Iīve posted it wrongly: in direct law thereīs switch in ELAC bias as slats extend from zero, but thatīs as much as my FCOM would let me know. Did you get your data from maintenance manual?
