Fuel distribution between wing and centre tanks at t/o
The AAIB report states:
The aircraft was serviceable on departure from Beijing
and there were no relevant reported defects. It departed
with 79,000 kg of Jet A-1 fuel on board, and the planned
arrival fuel at London (Heathrow) was 6,900 kg.
My understanding is that the centre tank can hold 80,000 kg of fuel, and each wing tank can hold 29,000 kg.
Doesn't this suggest the aircraft could have completed this flight using just fuel from the centre tank!
Does anyone know how the fuel was distributed between these tanks?
