I just got to ask what that is.

The history of the re-release concept was when long range non-stop flights were first introduced it was a way to get around the international reserve fuel requirement for the whole route. In some cases if you carried the entire amount of fuel you would arrive with 2.5 hours of fuel which you don’t really need and would result in less payload being carried.

| Quoting thegman (Reply 5): Is this the same or not to ‘reserve fuel’? Because I feel like the number is very low. |
Flights are fueled for:
This is a very basic summary. Most airlines have a few other fuel categories. I should also add that there is nothing wrong with burning into your reserve fuel, but obviously it’s not ideal and shouldn’t be a regular occurrence.

ah.. Thank you. So it is a little bit like decision point procedures to isolated islands in principle or completely different?

In the EASA ATPL syllabus this is the idealized breakdown for a typical flight:
— Taxi fuel.
— Trip fuel. Take-off to destination.
— Contingency fuel. 5% of trip fuel or 5 minutes at holding speed 1500 feet above alternate airport, whichever is greater. For unexpected reroutings and such.
— Alternate fuel. From destination to alternate if you go to the alternate.
— Final Reserve. 30 minutes at holding speed 1500 feet above the alternate airport.
| Quoting tommy1808 (Reply 9): So it is a little bit like decision point procedures to isolated islands in principle or completely different? |
For isolated airports with no workable alternates, alternate and final reserve are replaced by a reserve calculated as 2 hour at cruising speed.
For long haul flights the rules change because carrying 5% contingency just isn’t reasonable. For example with alternates en route, contingency fuel can be decreased based on various parameters. Say you’re going from A to C and half way downroute there is viable alternate B. Contingency fuel can be calculated based on the trip fuel B-C instead of as in the normal rules A-C.
Description
As in many facets of aviation, Fuel Planning has a list of specific terms and definitions of its own. The following list identifies the most critical of these terms. Different terms or names for the same concept are often used interchangeably by different regulatory authorities or flight planning organizations. The most common of these variants preface the definitions that follow.
Definitions
Additional Fuel
Additional fuel is fuel which is added to comply with a specific regulatory or company requirement. Examples include ETOPS fuel, fuel required for a remote or island destination where no alternate is available and fuel required to satisfy an Minimum Equipment List (MEL) or Configuration Deviation List performance penalty.
Alternate Fuel
Alternate fuel is the amount of fuel required from the missed approach point at the destination aerodrome until landing at the alternate aerodrome. It takes into account the required fuel for:
When two alternates are required by the Authority, alternate fuel must be sufficient to proceed to the alternate which requires the greater amount of fuel.
Ballast Fuel
Ballast fuel is sometimes carried to maintain the aircraft centre of gravity within limits. In certain aeroplanes, a zero fuel weight above a defined threshold requires that a minimum amount of fuel be carried in the wings through all phases of flight to prevent excessive wing bending. In both cases, this fuel is considered ballast and, under anything other than emergency circumstances, is not to be burned during the flight.
Block Fuel / Ramp Fuel / Total Fuel On Board
Block fuel is the total fuel required for the flight and is the sum of the Taxi fuel, the Trip fuel, the Contingency fuel, the Alternate fuel, the Final Reserve fuel, the Additional fuel and any Extra fuel carried.
Contingency Fuel / Route Reserve
Contingency fuel is carried to account for additional enroute fuel consumption caused by wind, routing changes or ATM: ATM/CNS restrictions. According to ICAO Annex 6, the recommended minimum contingency fuel is the greater of 5% of the trip fuel or 5 minutes holding consumption at 1500′ above destination airfield elevation computed based on calculated arrival weight. However, some regulators have eliminated the minimum time requirement and some have increased the recommended time interval in their National Regulations. As well, some regulators allow contingency fuel reduction to 3% of trip fuel, or to specific time increments, with use of enroute alternates and conditional upon demonstrated performance criteria from the Operator. At least one authority allows, under very specific circumstances, for contingency fuel to be reduced to 0. In all cases, an Operator can direct that its crews carry contingency fuel in excess of that required by their National Aviation Authority (NAA).
Extra Fuel
Fuel added at the discretion of the Captain and/or the dispatcher
Final Reserve Fuel / Fixed Reserve Fuel / Holding Fuel
Final reserve fuel is the minimum fuel required to fly for 30 minutes at 1,500 feet above the alternate aerodrome or, if an alternate is not required, at the destination aerodrome at holding speed in ISA conditions. Some Regulating Authorities require sufficient fuel to hold for 45 minutes.
Minimum Brake Release Fuel
Minimum brake release fuel is that quantity of fuel which, at the commencement of the takeoff roll, complies with all regulatory requirements for the flight in question. This is the minimum legal fuel required for departure.
Reserve Fuel / Minimum Diversion Fuel
Reserve fuel is the sum of Alternate fuel plus Final Reserve fuel.
Taxi Fuel
Taxi fuel is the fuel used prior to takeoff and will normally include pre-start APU consumption, engine start and taxi fuel. Taxi fuel is usually a fixed quantity for an average taxi duration. However, local conditions at the departure aerodrome such as average taxi time, normal ground delays and any anticipated deicing delays should be taken into consideration and the taxi fuel adjusted accordingly.
Trip Fuel / Burn / Fuel to Destination
The Trip fuel is the required fuel quantity from brake release on takeoff at the departure aerodrome to the landing touchdown at the destination aerodrome. This quantity includes the fuel required for:
Trip fuel must be adjusted to account for any additional fuel that would be required for known ATS restrictions that would result in delayed climb to or early descent from planned cruising altitude.
