easyJet Fuel Policy (last updated: Feb 2013) Flashcards
What is easyJets’ 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.
What comprises Taxi Fuel? What can not be exceeded with taxi fuel on board?
Fuel expected to be used prior to take-off; including: -engine start, -taxi -APU consumption. Maximum ramp weight may not be exceeded with taxi fuel on board.
What five components comprise ‘Trip Fuel’?
Fuel for; - take-off - climb (taking into account the expected departure procedure) - cruise (including step climbs if any) - descent (expected STAR and instrument approach) - landing procedure at the destination runway.
In the basic fuel planning case, what is ‘Contingency Fuel’?
Contingency Fuel shall be the higher of: - 5% of the planned Trip Fuel or (in the event of in-flight replanning, 5% of the Trip Fuel for the remainder of the flight.) - Fuel to fly for 5 minutes at holding speed at 1500 ft above the destination aerodrome in standard conditions.
What is contingency fuel for?
Fuel to cover deviations from the planned operating conditions such as: - unfavourable variations in cruise altitude or track, - deviations from the forecast wind values, or - any other unforeseen adverse circumstances.
What is Alternate Fuel?
Fuel to reach the alternate aerodrome, taking into account:
Fuel from a missed approach from the applicable MDA/DH at the destination aerodrome to the missed approach altitude taking into account the complete missed approach procedure.
Fuel from the missed approach altitude to CLIMB,
CRUISE at LRC speed,
DESCENT to the alternate aerodrome from an en-route transition point using the expected arrival procedure.
Fuel for the approach and landing at alternate aerodrome.
When two destination alternates are required, alternate fuel should be sufficient for the alternate which requires the greater amount of fuel.
What is Final Reserve Fuel?
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 Extra Fuel? When is this carried?
Extra fuel is carried at the discretion of the Commander. It will be carried when there are sound operational or economic reasons for doing so. Flight crew will board Extra Fuel only if a strong possibility exists that it will be used. Extra Fuel should be considered in terms of endurance (time) and not quantity of fuel. If there is a likelihood of a diversion at the destination, then fuel should normally be carried to allow the Commercial Alternate to be reached with Normal Reserves.
What guidelines do easyJet suggest when considering the carriage of Extra Fuel?
Thunderstorms are forecast. Destination weather is forecast or reported to be at or near operational landing limits. An unscheduled runway closure, affecting the arrival rate, is likely because of: – Freezing precipitation (runway treatment) – Moderate to heavy intensity snowfall (snow removal). Crosswind/contaminated runway limitations (aircraft specific). ATC - Anticipated departure and arrival delays. Fuel for additional approaches at destination. Forecast icing conditions en-route.
What is the penalty for the carriage of Extra Fuel?
The penalty for carriage of extra fuel is normally:
3.0% of extra fuel per hour of flight
Example: On a 2 hour sector up to 6% of the extra fuel uplifted will be burned off due to the increased aircraft weight.
In the Alternates List on the LIDO OFP,
What does the ‘F’ or ‘C’ designator indicate?
F - Fuel Alternate
C - Commercial Alternate (numbered according to priority.)
OMB 5.2.8
When is a ‘Fuel Alternate’ used as the destination alternate?
Fuel alternates should only be chosen when;
the weather and operational conditions at the destination make a diversion unlikely (low risk)
When is a Commercial Alternate to be considered as the destination alternate?
What factors may lead you to use the Commercial Alternate?
Consider the risk of a diversion when considering the Commercial alternate.
i.e. Diversion is likely.
The following factors should be evaluated in order to determine if a diversion is considered likely:
- Thunderstorms are forecast at the destination aerodrome
- Weather conditions close to operational minima at the destination.
- Winds exceeding crosswind limits.
- FZRA / DZ and SN removal during winter operations.
Within basic fuel planning,
can you depart without selecting a suitable destination alternate?
No.
When can an IFR flight depart without selecting a useable destination alternate?
Either; Flight dispatched under the Alternative Flight Planning Procedures
i.e. must take ‘Additional Fuel’ of 15 mins at 1,500 feet in ISA conditions.
(Section 8.1.7.4.5, “No Destination Alternate Aerodrome Procedure”.)
- Flight time less than six hours
- Two separate runways are available and usable at the destination
- Wx +- 1 hour from ETA at the destination;
- ceiling at least 2,000 ft or ‘Circling Height +500 ft,’ whichever is greater
- VIS at least 5 km.
Or; The destination aerodrome is isolated.
