No guys, I dont do my own thing and am by the book. All I am asking is the Boeing Dispatch Deviation guide reading into if you have a centre tank pump u/s and you are operating under the mel and you have 2000kgs in the centre tank...for take off am I correct in the reading that you have the cross feed open and the remaining centre tank fuel pump on? Having a cross feed open on t/o is not up my alley. Enlighten me chaps
