The technique of 'running down' wing tanks by retaining centre tank fuel is an effective solution to that, as long as CofG and ZFM issues are addressed and there is enough in the wings to cope with that 10,000,000 to 1 double ctre tank pump failure. The 'cold soak' lines are good, but don't help much in winter at 'cold' airfields.
