Takeoff 

Climb to cruise level 

Flight from the end of climb to the beginning of descent, including any step climb/descent 

Flight from the beginning of descent to the beginning of  approach, 

Approach 

Landing at the destination airport 

1.1.1.3. Contingency Fuel 

Contingency fuel is the greatest of two quantities: 

The fuel necessary to fly for 5 minutes at 1500 feet above the destination airport at holding speed in ISA conditions 

One of the following quantities: 

5% of trip fuel, 

With airworthiness approval, 3% of trip fuel with an available en route alternate airport*, 

With airworthiness approval, the necessary fuel to fly for 15 minutes at 1500 feet above the destination airport, at holding speed, in ISA conditions; the Operator must have a program to monitor fuel consumption on each individual route / aircraft combination and must use the program to statistically calculate contingency fuel 

The required fuel to fly for 20 minutes, based upon trip fuel consumption, provided the operator has a fuel consumption monitoring program for individual airplanes and uses the resulting data for fuel calculation. 

* Appendix 1 to AMC-OPS 1.255 explains how to reduce contingency fuel from 5% to 3%: 

“AMC-OPS 1.255 If an en-route alternate is available within a circle having a radius equal to 20% of the total flight plan distance, the centre of which lies on the planned route at a distance from the destination of 25% of the total flight plan distance, or at 20% of the total flight plan distance plus 50nm, whichever is greater” 

1.1.1.4. Alternate Fuel 

Alternate fuel takes into account the necessary fuel for: 

Missed approach at the destination airport 

Climb from the missed approach altitude to the cruise level 

Flight from the end of climb to the beginning of descent 

Flight from the beginning of descent to the beginning of the approach 

Approach 

Landing at the alternate airport 

When two alternate airports are required*, alternate fuel should be sufficient to proceed to the alternate which requires the greater amount of fuel. 

* Two alternate airports are required, when: “JAR-OPS 1.295 

(1) The appropriate weather reports or forecasts for the destination, or any combination thereof, indicate that during a period commencing 1 hour before and ending 1 hour after the estimated time of arrival, the weather conditions will be below the applicable planning minima; or 

(2) No meteorological information is available.” 

1.1.1.5. Final Reserve Fuel 

The final reserve fuel is the minimum fuel required to fly for 30 minutes at 1,500 feet above the alternate airport or destination airport, if an alternate is not required, at holding speed in ISA conditions. 

1.1.1.6. Additional Fuel 

“AMC OPS 1.255 

1.6 […] the minimum additional fuel which should permit: 

a. Holding for 15 minutes at 1500 ft (450 m) above aerodrome elevation in standard conditions, when a flight is operated under IFR without a destination alternate, in accordance with JAR-OPS 1.295; and 

b. Following the possible failure of a power unit or loss of pressurisation, based on the assumption that such a failure occurs at the most critical point along the route, the aeroplane to: 

i. Descend as necessary and proceed to an adequate aerodrome; and 

ii. Hold there for 15 minutes at 1500 ft (450 m) above aerodrome elevation in standard conditions; and 

iii. Make an approach and landing, except that additional fuel is only required, if the minimum amount of fuel calculated in accordance with sub-paragraphs 1.2 to 

1.5 above is not sufficient for such an event.” 

1.1.1.7. Extra Fuel Extra fuel is at the Captain’s discretion. 

1.1.2. Isolated Airport Procedure 

For such an airport, there is no destination alternate. The regulatory takeoff fuel quantity must include: 

Taxi fuel 

Trip fuel 

Contingency fuel, as calculated in the standard fuel policy 

Additional fuel: This quantity must be higher than the quantity necessary for a two hour flight at cruise rating above the destination airport; final reserve fuel is included in this amount 

Extra fuel, is at the Captain’s discretion. 

1.1.3. Unrequired Destination Alternate Airport 

An alternate airport is not required, when all of the following conditions are met:
