3.—(1) The aeroplane operator must use the following formula to compute fuel use according to Method A()—
where—
FN = Fuel used for the flight under consideration (i.e. flight N) determined using Method A (in tonnes);
TN = Amount of fuel contained in aeroplane tanks once fuel uplifts for the flight under consideration (i.e. flight N) are complete (in tonnes);
TN+1 = Amount of fuel contained in aeroplane tanks once fuel uplifts for the subsequent flight (i.e. flight N+1) are complete (in tonnes); and
UN+1 = Sum of fuel uplifts for the subsequent flight (i.e. flight N+1) measured in volume and multiplied with a density value (in tonnes)().
(2) The aeroplane operator performing on an ad-hoc basis flights attributed to another aeroplane operator must provide to the latter the fuel measurement values according to the Block-off/Block-on method.
(3) Where no fuel uplift for the flight or subsequent flight takes place, the amount of fuel contained in aeroplane tanks (TN or TN+1) must be determined at block-off for the flight or subsequent flight. In exceptional cases the variable TN+1 cannot be determined. This is the case when an aeroplane performs activities other than a flight, including undergoing major maintenance involving the emptying of the tanks, after the flight to be monitored. In such case the aeroplane operator may substitute the quantity “TN+1 + UN+1” with the amount of fuel remaining in tanks at the start of the subsequent activity of the aeroplane or fuel in tanks at Block-on, as recorded by technical logs.
