Currently on a flight, upto the stage of reaching equivalence in the tanks, got the upper EICAS tank/eng message, so did the usual. Was fine.About 10 mins later up pops a Caution and X FEED CONFIG. I look at the EICAS shows that I have 9.1, 9.1, 9.3, 9.1 in the tanks, feeding tank to engine. I switched back on the x-feeds, and overide pumps and I get the TANK/ENG message again, so I go back to tank/eng config and get an alert with X FEED CONFIG again.Any ideas?First flight with the patch, its amazing btw, really smooth now and just awesome.

this happed to me a few times. just kept fiddling with it until the EICAS message dissapeared. Still want to know how to properly adjust the pumps etc..Andrew

EDIT: I had the same problem, but it turned out in my case that Main2 had about 1,000lbs more fuel than Main3 (Main1 19,000lbs, Main2 20,000lbs, Main3 19,000lbs, Main4 19,000lbs). I re-enabled the crossfeeds and shutoff all fuel pumps except for Main2 until it was even with the rest of the tanks. Then after turning on all pumps again and switching into direct-to-engine, the config error went away. Thanks,Jason
