Sorry to ask a slight side question 'The Lead Sparrow,' hope you don't mind. Do the fuel tankering charts take into account just the extra fuel burnt in transporting or do they take into account all the factors??
Quote the A320 FCOM: "The computed optimum takeoff weight is based on the additional fuel consumption needed for the transport of the extra (tankered) fuel and it is the weight at which optimum profit can be achieved."
Other factors obviously include extra brake/engine/tire wear and not just extra fuel burn. Any ideas?
