Wing ice
Our procedure on the A330/340 is to transfer the outer wing tank fuel on arrival, if not moved automatically, and then refuel as normal. The warmer induced fuel to the outer tanks rapidly moves any surface frost/ice caused by the humidity.
No delays and done during a one hour transit.
Transferring fuel from the centre or another tank is just moving cooled fuel which will have little or no effect. Space for that fuel has also to be created.
