Paragraph 6 Fuel UpliftI1

For flights with a fuel uplift, unless the subsequent flight has no uplift the aeroplane operator must use the following formula to compute fuel use according to the Fuel Uplift Method^f1—

$$F_N=U_N$$

where—

• F_N = Fuel used for the flight under consideration (i.e. flight _N) determined using fuel uplift (in tonnes); and

• U_N = Fuel uplift for the flight considered, measured in volume and multiplied with a density value (in tonnes)^f2.

For flight(s) without a fuel uplift (i.e. flight _N+1, …, flight _N+n), the aeroplane operator must use the following formula to allocate fuel use from the prior fuel uplift (i.e. from flight _N) proportionally to block hour—

$$F_N=U_N\ast \left[\frac{B{H}_N}{B{H}_N\pm B{H}_{N\pm 1}\pm \cdot \cdot \cdot \pm B{H}_{N\pm n}}\right]$$ $$F_{N\pm 1}=U_N\ast \left[\frac{B{H}_{N\pm 1}}{B{H}_N\pm B{H}_{N\pm 1}\pm \cdot \cdot \cdot \pm B{H}_{N\pm n}}\right]$$ $$F_{N\pm n}=U_N\ast \left[\frac{B{H}_{N\pm n}}{B{H}_N\pm B{H}_{N\pm 1}\pm \cdot \cdot \cdot \pm B{H}_{N\pm n}}\right]$$

where—

• F_N = Fuel used for the flight under consideration (i.e. flight _N) determined using fuel uplift (in tonnes);

• F_N+1 = Fuel used for the subsequent flight (i.e. flight _N+1) determined using fuel uplift (in tonnes);

• F_N+n = Fuel used for the follow-on flight (i.e. flight _N+n) determined using fuel uplift (in tonnes);

• U_N = Fuel uplift for the flight under consideration (i.e. flight _N) (in tonnes)^f3;

• BH_N = Block hour for the flight under consideration (i.e. flight _N) (in hours);

• BH_N+1 = Block hour for the subsequent flight (i.e. flight _N+1) (in hours); and

• BH_N+n = Block hour for the follow-on flight (i.e. flight _N+n) (in hours).
