OMA 8.1 Fuel policy Flashcards
What is the easyjet fuel policy ?
easyJet’s fuel policy is to carry the minimum amount of fuel necessary to safely and efficiently complete the flight while meeting regulatory requirements and maintaining operational flexibility.
- All extra shall be justified
- basic fuel planning should be the norm
- still allow sufficient margin for contingency
- captain remain responsible to adjust fuel as appropriate
easyJet accepts the risk of diversion that is associated with the application and adherence to this fuel policy. Costs associated with any potential diversions are outweighed by savings that this policy delivers.
Basic fuel planning, what is the minimum required fuel ?
- Taxi fuel
- Trip fuel
- contingency fuel
- alternate fuel
- additional fuel (if required)
- final reserve fuel
- extra fuel
What is the taxi fuel ?
Fuel expected to be used prior to take-off, including engine start, taxi and APU consumption. Maximum ramp weight may not be exceeded with taxi fuel on board.
What is the trip fuel ?
Fuel for take-off and climb to from departure aerodrome to cruise altitude taking into account the expected departure routing; and
Fuel for cruise including step climbs if any; and
Fuel for descent, taking into account the expected arrival procedure; and
Fuel for approach and landing at the destination aerodrome.
What is the contingency fuel ?
Contingency fuel is to cover for possible deviations between the planned and actual operating conditions such as unfavourable variations in cruise altitude or track, deviations from the forecast wind values or any other unforeseen adverse circumstances.
Contingency fuel may be used at any time after commencement of the flight i.e. after push-back or engine start.
If Statistical Contingency Fuel (SCF) data is available this will be indicated on the OFP and contingency fuel is the greater of:
95% coverage (CONT95), or 99% coverage (CONT99) for selected city pairs, based upon operational factors, and;
an amount to fly for 5 minutes at holding speed at 1500 ft above the destination aerodrome in standard conditions.
If SCF data is not available, this will be indicated on the OFP and contingency fuel is the greater of:
5% of the planned trip fuel, and;
an amount to fly for 5 minutes at holding speed at 1500 ft above the destination aerodrome in standard conditions.
OMA 8.1.7.5.5
What is the alternate fuel ?
Fuel to reach the alternate aerodrome, taking into account:
- fuel from missed approach MDA/DH at dest missed approach alt with complete missed approach
- from missed approach alt to climb and cruise, descent to alternate from enroute to arrival proc
- fuel for approach and landing to alternate
- if two alternate, fuel to reach the furthest
What is final reserve ?
Fuel to fly for 30 minutes at holding speed at 1500 ft above destination alternate aerodrome elevation in standard conditions, calculated with estimated weight on arrival at the alternate or the destination when no alternate is required.
What is the penalty of extra fuel carriage ?
The penalty for carriage of extra fuel is normally 3.0% of extra fuel per hour of flight (i.e. on a 2 hour sector up to 6% of the extra fuel uplifted will be burned off due to the increased aircraft weight.).
What is the specific gravity of the fuel JET A/A1 and oil ?
0,8, oil 0,88
