Refuelling an airbus to maximum The airbus A350 aircraft when being refuelled seems to drop when the wings are filled.How  much is the drop from empty to full.Thankyou
That’s going to depend on a lot of things including how well serviced the struts are, what the existing payload on the aircraft is and whether the aircraft is parked on any sort of grade. 

I don’t work the A350, but I work other heavy aircraft and I’ve had them “settle” quite a bit when putting on a full fuel load.
