the -400F -400BCF (as involved in the Bagram accident) -400BDSF -400ERF do not have activated stab tanks. So thats out of the question.
As the center tank quantity decreases and wing fuel from the main tanks (wings) is burned off, the CG continues to move aft.
Landing ASAP before it gets worse comes to mind.
Had it not been for the crew of the Korean -400F contacting load control at HQ in Seoul, immediately after takeoff and them telling the relief pilot and captain to go downstairs to move pallets forward, the plane would have landed with more than 43.7% MAC CG. Some 10.7% aft of the limit!
Considering the CG was 37.8% MAC at takeoff (4.8% aft of the limit) and not including the subsequent load shift by the crew, the resulting fuel burnoff to Seoul would have resulted in a CG shift of 5.9% MAC.
Amazing that HQ advised them to continue or that the captain didnt just land immediately at Oslo overweight with a CG 4.8% MAC aft of limit instead of the 7.2% MAC aft of limit at Seoul. Again, land ASAP comes to mind.
In the case of the National -400BCF, the aircraft was obviously not airborn anywhere near enough time for a burnoff of center tank and most of the wings to result in the CG moving AFT.
