NCO.OP.125 – Fuel, energy and oil supply — aeroplanes or helicopters

SI 2024 No. 1290

The pilot‑in‑command of an aircraft must:

1. ensure that the aircraft carries a sufficient quantity of fuel or energy and oil, taking into account the weather conditions, any element affecting the performance of the aircraft, any delays that are expected in flight and any contingencies that may reasonably be expected to affect the flight;

2. plan a quantity of fuel or energy to be protected as final reserve fuel or energy to ensure a safe landing, taking into account points (1) and (2), in that priority order, to determine the quantity of the final reserve fuel or energy:

   1. the severity of the hazard to persons or property that could result from an emergency landing after fuel or energy starvation;
   2. the likelihood of unexpected circumstances resulting in the final reserve fuel or energy may no longer be protected;

3. commence a flight only if the aircraft carries sufficient fuel or energy and oil:

   1. when no destination alternate aerodrome is required, to fly to the aerodrome or operating site of intended landing, plus the final reserve fuel or energy; or
   2. when a destination alternate aerodrome is required, to fly to the aerodrome or operating site of intended landing, and afterwards, to an alternate aerodrome, plus the final reserve fuel or energy.
