Learn the Airbus A380 fuel capacity in litres and tonnes, where its 11 tanks sit, and how automatic engine feed, transfer and trim work.
The Airbus A380-800 can carry about 320,000 litres (roughly 84,500 US gallons) of jet fuel, equivalent to around 250–255 tonnes depending on fuel density. Its 11 tanks supply four dedicated engine-feed tanks, while automatic pumps and valves manage engine supply, centre of gravity, wing loading and the tail trim tank.
For this Aviation & Real-World Flying answer, we mean the production A380-800. The headline capacity is not necessarily the amount available for a particular flight: payload, take-off weight, reserves, fuel density and the aircraft's approved configuration all affect the actual uplift.
What is the Airbus A380's maximum fuel capacity?
The commonly quoted maximum Airbus A380 fuel capacity is approximately 320,000 litres. Detailed references may differ slightly because of rounding, aircraft standard and whether they report total or usable volume.
Airlines plan fuel by mass rather than volume. At a representative density of 0.79 kilograms per litre, 320,000 litres weighs about 252,800 kilograms; a different fuel temperature or batch density changes that mass. This is why entering 320,000 kilograms into a simulator field labelled litres produces a serious loading error.
Tank volume also should not be confused with fuel that can be delivered to the engines. Our explanation of usable, unusable and reserve fuel covers that distinction.
Where are the A380 fuel tanks?
The A380 distributes fuel between ten wing tanks and one trim tank in the horizontal stabiliser.
| Tank group | Number | Normal purpose |
|---|---|---|
| Outer, mid and inner tanks | Six | Bulk storage and scheduled transfer into the feed tanks |
| Engine-feed tanks | Four | One normal fuel source for each of the four engines |
| Trim tank | One | Centre-of-gravity control and additional storage in the tailplane |
Putting most of the fuel in the wings keeps it close to the engines and helps counter wing-bending loads in flight. We explain the structural reasoning in more detail in our guide to how wing tanks reduce loads and assist aircraft balance.
How does the A380 fuel system feed four engines?
In normal operation, each engine draws from its own feed tank while the automatic fuel-control system replenishes those feed tanks from the surrounding storage tanks.
- Refuel and measure. Pressure-refuelling equipment distributes the selected load between the tanks. Tank sensors and processing computers calculate fuel on board as a mass; our guide to fuel quantity sensing and cockpit indications explains the measurement principles.
- Transfer into the feed tanks. Transfer pumps and valves move fuel from the outer, mid and inner storage tanks according to programmed quantity, balance and structural-load schedules.
- Supply the engines. Electric pumps send fuel from each feed tank through its engine fuel line. Engine-mounted equipment then meters and pressurises it for combustion.
- Control lateral balance. The computers monitor left-to-right distribution and generate warnings or alter transfer logic when quantities diverge beyond permitted limits.
- Provide an alternate path. Crossfeed valves can connect feed lines so that an engine can receive fuel from another feed source when required by an abnormal or balancing procedure.
Crossfeed and transfer are not the same thing. Transfer physically moves fuel between tanks; crossfeed changes which feed tank or manifold supplies an engine. Confusing the two is a common cause of worsening imbalances in detailed A380 simulations.
What does the A380 trim tank do?
The trim tank moves the aircraft's centre of gravity within an efficient approved range rather than feeding an engine directly during normal operation.
When flight conditions permit, automatic transfers can move fuel aft during cruise. The resulting aft centre of gravity reduces the balancing force required from the tailplane and therefore reduces drag. Before descent and landing, the system transfers fuel forward again to satisfy landing centre-of-gravity limits.
The transfer sequence is not simply “empty the outer tanks first”. Fuel location also affects wing loads, so the computers consider flight phase, tank quantity and system status. A transfer fault may leave fuel trapped in a storage tank even though the total fuel-on-board indication still appears adequate.
What happens if a pump fails or the fuel becomes unbalanced?
The A380 has redundant pump and feed paths, but the response depends on which pump, valve, sensor or tank is affected.
- A single failed pump does not normally remove all pressure from that engine's feed tank because another pumping path is available.
- Crossfeed can provide an alternate engine supply when the relevant procedure calls for it.
- A transfer failure can leave usable-looking fuel outside the feed tanks, making individual tank quantities as important as the total.
- A suspected leak requires isolation and checklist action; opening every crossfeed valve can allow more fuel to reach the leaking side.
Crews follow the aircraft's ECAM actions and operating procedures rather than trying to balance every tank manually. In a simulator, leaving automatic transfer enabled is usually the correct choice unless the add-on's checklist directs otherwise.
Does an A380 take off with full fuel tanks?
No; an A380 normally carries the calculated block fuel for the route rather than filling every tank.
Block fuel includes taxi fuel, trip fuel, contingency allowances, alternate fuel, final reserve and any operational extra. Carrying unnecessary fuel increases take-off weight and fuel burn, while a high passenger or cargo load may prevent the aircraft from taking both maximum payload and maximum fuel without exceeding a structural weight limit.
Can the Airbus A380 dump fuel?
Yes, the A380 has a fuel-jettison system for reducing weight when circumstances permit, but jettison is not used during normal fuel balancing.
The crew selects the system and monitors the target weight, tank quantities and balance while fuel leaves through dedicated outlets. Simulator implementation varies; A380X users can follow our explanation of how fuel jettison and fuel-on-board monitoring are modelled.
Why might an A380 simulator show different fuel figures?
A simulator may simplify the A380's 11-tank architecture or calculate fuel from a different density than the figure used in a flight plan.
- Check whether the entry field expects kilograms, pounds, litres or US gallons.
- Use either the add-on's loading tool or the simulator's fuel menu, not both after the aircraft has initialised.
- Compare individual tank quantities when total fuel is high but an engine-feed warning appears.
- Do not manually fill the trim tank without a compatible loading calculation; an incorrect tail load can put the centre of gravity outside limits.
- Expect simplified aircraft to omit automatic trim transfer, realistic crossfeed logic or jettison even when the visual model is an A380.
