An operator must base the company fuel policy, including calculation of the amount of fuel to be on board for departure, on the planning criteria outlined in the following subparagraphs.
The usable fuel to be on board for departure must be the amount of:
• Taxi Fuel
• Trip Fuel
• Contingency Fuel
• Alternate Fuel
• Final Reserve Fuel
• Minimum Additional Fuel
• Extra Fuel
Taxi fuel shall not be less than the amount, expected to be used prior to take-off. Local conditions at the departure aerodrome and APU consumption shall be taken into account.
Trip fuel shall include Fuel:
• for take-off and climb from aerodrome elevation to initial cruising level/altitude, taking into account the expected departure routing,
• from top of climb to top of descent, including any step climb/descent,
• from top of descent to the point where the approach is initiated, taking into account the expected arrival procedure and
• for approach and landing at the destination aerodrome.
The fuel required to for unseen factors which could have influence on the fuel consumption to the destination aerodrome. Such as deviation of an individual ACFT from the expected consumption data, deviation from meteorological conditions and deviation from planned routings, cruising levels or cruising altitudes.
Alternate fuel shall include fuel for:
• a missed approach from the applicable Minimum Descent Altitude (MDA)/Decision Height (DH) at the Destination Aerodrome to missed approach altitude, taking into account the complete missed approach procedure,
• climb from missed approach altitude to cruising level/altitude, taking into account the expected departure routing,
• cruise from top of climb to top of descent, taking into account the expected routing,
• descent from top of descent to the point where the approach is initiated, taking into account the expected arrival procedure and
• executing an approach and landing at the destination alternate aerodrome.
Final Reserve Fuel
Final reserve fuel shall be enough fuel to fly for 30 MIN at holding speed at 1500ft (450m) above aerodrome elevation in standard conditions, calculated with the estimated mass on arrival at the destination alternate aerodrome or the destination aerodrome, when no destination alternate aerodrome is required.
Minimum Additional Fuel
The minimum additional fuel which shall permit the aircraft to descend as necessary and proceed to an adequate alternate aerodrome in the event of engine failure or loss of pressurization, whichever requires the greater amount of fuel based on the assumption that such a failure occurs at the most critical point along the route
a) hold there for 15 MIN at 1500ft (450m) above airport elevation in standard conditions; and make an approach and landing;
b) Holding for 15 MIN at 1500ft (450m) above destination airport elevation in standard conditions, when a flight is operated without a destination alternate aerodrome.
- Note: Additional fuel is only required, if the minimum amount of fuel calculated for
- • Trip fuel
- • Contingency fuel
- • Alternate fuel
- • Final reserve fuel
- is not sufficient for such an event.
Extra fuel is fuel which shall be on the discretion of the commander.
