To what temperature does anything that isn't warm blooded or radioactive adjust to and stabilize at?
If an aircraft cold soaks for 12 hours on a ramp at -10*C, exactly WHAT temperature do YOU think that plane and everything in it is busy stabilizing at?
If you spend many hours cooling the fuel in your tanks to -25*C and then refuel from a truck that is holding fuel that has stabilized at the average ambient temperature of say... -5*C... would you care to guess what temperature range your fuel will be upon refueling?
