  "heading": "Fuel Uplift",
  "text": "(1) 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—\nF N = U N where—\nFN = Fuel used for the flight under consideration (i.e. flight N) determined using fuel uplift (in tonnes); and\nUN = Fuel uplift for the flight considered, measured in volume and multiplied with a density value (in tonnes).\n(2) 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—\nF N = U N ∗[ B H N B H N ±B H N±1 ±⋅⋅⋅±B H N±n ] F N±1 = U N ∗[ B H N±1 B H N ±B H N±1 ±⋅⋅⋅±B H N±n ] F N±n = U N ∗[ B H N±n B H N ±B H N±1 ±⋅⋅⋅±B H N±n ] where—\nFN = Fuel used for the flight under consideration (i.e. flight N) determined using fuel uplift (in tonnes);\nFN+1 = Fuel used for the subsequent flight (i.e. flight N+1) determined using fuel uplift (in tonnes);\nFN+n = Fuel used for the follow-on flight (i.e. flight N+n) determined using fuel uplift (in tonnes);\nUN = Fuel uplift for the flight under consideration (i.e. flight N) (in tonnes);\nBHN = Block hour for the flight under consideration (i.e. flight N) (in hours);\nBHN+1 = Block hour for the subsequent flight (i.e. flight N+1) (in hours); and\nBHN+n = Block hour for the follow-on flight (i.e. flight N+n) (in hours).",
