OUTER TO INNER XFREach Outer TK cycle its Inner TK between 3500kg and 4000kg until it is empty. The valves then close after 5min. If no AUTO XFR available, manual xfr via refueling pipe and inlet valve possible.
CENTER TO INNER XFR A332The center TK pumps run continously.Each inner TK inlet valve controls the tranfer by cycling its inner TK between FULL and 2000kgbelow full until it is empty.Then pmps & vlvs close.
