Narrative:
Due to the strong winds out of the west; we were filed well north. The flight was weight restricted with an alternate and we had a full fuel load. About 4.5 hours into the 6.3-hour flight; we noticed the right outer fuel wing tank temperature had dropped to -39C. The captain brought dispatch and maintenance control into the discussion; after looking at the QRH we decided to descend and increased the speed to warm the fuel. We were not using the fuel from the outer tanks at the time; the inner tank temperatures were -28C and -30C. It was difficult to find information in the QRH and flight manual limitations sections on where the minimum fuel temp limitation exists. Is it at each individual fuel tank?
