There are also some pax B744 without a stab tank. BA has four aircraft.
The B744 fuel system just uses the fuel in the correct order. It is not very clever, uses point sensors to initiate fuel transfer as required, and commands the pilots to close the cross feed valves at the right time.
The A330 is clever. It moves the fuel back during the climb, then fwd in small doses, and sometimes will move the fuel back a second time (if centre tank fuel used).
One thing confuses me as an engineer on the B744 is why different airlines start using the stab tank at different fuel qtys. If you let the aircraft refuel itself, stab tank starts to be used at around 129000 kgs, but BA starts using it a lot later. What is the reasoning behind this?
