If and when the Company is able to
- present aircraft that are perfectly aero-dynamic, have engines tuned to perfection and trimmed with load that's spot-on,
- guarantee that winds and levels will be as assumed by the flight plan,
it may be able to justifiably report on additional fuel carriage with some credibility. I think the data all too nebulous to be of any value, especially as the reasons for additional fuel carriage is unknown.
As an aside, I wonder if Marketing consider the cost of additional fuel burn when they wish to add some dazzle-dazzle, whizz bang stuff?
