" Thanks I would like a small confirmation during climb/cruise. Should I keep the Main 1,4 pumps on until they reach 23500 Lb then turn the pumps off until the Main 2,3=Main 1,4+reserves or Should I keep Main 1,4 pumps off all the times until the Main 2,3=Main 1,4. Besides the scavange pump found out a small problem in fuel calculations: At alternate fuel should be at least 15000 Lb and destination 23000Lb. And of course landing is mandatory with fuel >12000 Lb José "
" To reach balanced fuel in tanks during climb and cruise I would do: Crossfeed 2 and 3 closed (2 and 3 are in tank to engine state now) All boost pumps set to ON No. 1 and 4 fuel boost pums to ON until 1 and 4 reaches 23 500 lbs of fuel after this condition is reached: No. 1 and 4 boost pump to off, 2 and 3 crossfeed valves move to open. When No. 2 and No. 3 equals the quantity in main tanks No. 1 and No. 4 plus adjacent reserve tanks then turn 1 and 4 boost pumps to ON. "
