Hi all. I was just wondering, even though damage is not modeled, should you turn off the center fuel pumps on the 737NG when you have exhausted the fuel in the center tank? This is just for realism's sake. Thanks in advance.Mike FluhartyJamaica, IA, USA

I think so :-)

Mike,Yes, you should actually let aprox 500kg or 1000lbs of fuel be left in the centre tank to keep the fuel pumps submerged. Hope it helps,

Thanks for the replies, and yes it does help. Thanks again, Mike

I have a question about the 737-700. I flew a flight lately where both of my wing tanks emptied and I could not get it to draw from the center tank. How do I correct this?

ensure you have the center fuel pumps in the on position, thats all thats too it

Todd,Alan is correct. Also you should usually draw fuel from the centre tank first, then the wing tanks. That is if you have more than 500kg/1000lbs in the centre tank. Hope it helps,

Todd,As Mats was saying draw fuel from the center tank first if you have more than 500kg/1000lbs of fuel in it but ensure that when you are re-fueling that you fill the wing tanks before putting anything in the center tank (although you should keep the min in the center tank at all times)Remember that 747 tradgedy when there was so little fuel in the center tank that the air conditioning unit (which is situated under the fuel tank in the 744 I think) got so hot that it heated the fuel to vapour unfortunately some electrical problem then sparked the vapour in the fuel tank...thats basically the reasoning behind it as well as keeping the fuel pumps immersed
