dc.description.abstractFuel burn is crucial to the efficiency of aircraft operation. Empirical analysis shows, that it takes on average ~ 0.2 kg fuel to transport 1 kg of weight over a distance of 1'000 km. It also takes an additional ~ 0.02 to 0.03 kg fuel per 1’000 km for every kg of weight added. This is known as the marginal fuel burn rate (MFB). The opposite is also true: a reduction in weight by one kg saves ~ 0.02 to 0.03 kg of fuel per 1’000 km or ~ 2 to 3 €cent respectively. To reduce the cost per available seat kilometre CASK of ~ 6 €cent by 1 ‰, the weight needs to be reduced by ~ 300 to 1'000 kg (structural or operational), depending on the aircraft type. The optimum range is between ~ 2'000 km and 5'000 km for A322, 7'000 km for A333 and 12'000 km for A388. For shorter or longer distances, operation is less efficient because of fuel burnt for climb and the trade-off between fuel, payload and distance due to limitations of aircraft structure.de_CH
