Hello,
in the last flight has fuel imbalance coming (due my mistake - forgot to switch off APU before departure  :-X), in 5 hours of flight difference of 1.1 tons, EICAS message rolled up.
So, in keeping with standard procedure for these cases XFER button on fuel control panel was swithed on, at that point in time in left tank was 6.3 and 7.4 in right tank. At landing time fuel disbalance has remained in 1.1 t. It means only one thing - fuel transfer pump is not working or working incorrectly
Is anyone face this problem also?
