The adjustment shall be based on the ratio between the typical in-use fuel consumption and the fuel consumption on the ageing cycle, but fuel consumption on the ageing cycle must not exceed typical in-use fuel consumption by more than 30 per cent.
L’ajustement doit s’appuyer sur le rapport entre la consommation habituelle normale de carburant en service et la consommation de carburant pendant le cycle de vieillissement, mais la seconde ne doit pas dépasser la première de plus de 30 %.
