Fuel Planning
I recently had a chat with one of the planners. I think there are 2 issues here. The final Vulcan transfer just north of the FI is relatively easy to explain. Bob T had swapped places with the other remaining Victor (which had a broken probe). This had 2 bearings on the situation. The other AC had to keep enough fuel to reach ASI without the planned AAR and the Victor/Victor transfer had taken part further south than planned (delayed by swap around ) which made matters even worse. The part I have difficulty with is understanding why it is that the short slot ac all landed with low fuel states. The supposition that it is anything to do with the Vulcan fuel figures is a red herring since they only transferred fuel to other Victors. It therefore must be that the Victor assumptions were wrong. I can only think that the ISA Deviation was unknown /unfactored.
