Runsick is correct.
There is a big diference between both tanks.
I know there is a diference in fuel freezing temps acording to the fuel used.
In case of JET A-1 is -47ºC.
My question was: Supose that we had the ECAM , disregarded because my freezing point is -47.
At some point , it reached , minus 47ºC. Instead of increasing speed , lowering one level , etc, may I only manually transfer fuel from the outers to the inners?
Thanks for your answers.
