Hi
Before start, if there is less than 1000kgs in the centre tanks, I leave off the centre pumps until after take off (assuming of course there is fuel in centre!)
I noticed for the first time, when I loaded the fuel I had 830kgs in the center and so the centre pumps were off. Taxiing out I did see a very small reduction - down to 800kgs just after take off. Assume some fuel still gets drawn from the centre in that case ?
Thanks
