What You'll Learn
The Airbus A380's fuel capacity is 315,292 litres
The Airbus A380, also known as the Superjumbo, is the largest commercial aircraft currently in operation. It has a range of more than 8,000 miles, enabled by its 11 fuel tanks, which have a combined capacity of 315,292 litres (or 250 metric tons).
The fuel capacity of the A380 is distributed across its 11 tanks as follows: the two inner tanks hold more than 90,600 litres; the two mid-tanks hold around 72,000 litres; inner engine 2 and 3 feed tanks contain 28,130 litres each; the outer engine 1 and 4 feed tanks each hold 26,974 litres; and the two outer tanks each hold 9,524 litres. Additionally, the tail tank can hold up to 23,698 litres and can be adjusted in flight for trimming purposes.
To manage its fuel system, the A380 utilises a sophisticated fuel management system developed using Model-Based Design and MATLAB tools. This system handles fuelling and defuelling operations on the ground, as well as fuel flow to engines and between tanks during flight. By optimising the aircraft's centre of gravity and reducing wing bending, the fuel management system contributes to the A380's performance and efficiency.
The A380 has demonstrated its fuel efficiency, with Singapore Airlines reporting that it burned 20% less fuel per seat-mile than their 747-400 fleet. Emirates also noted that the A380 has better fuel economy at Mach 0.86 than at 0.83.

The A380 has 11 fuel tanks
The Airbus A380 is the largest commercial aircraft currently in operation and has a range of more than 8,000 miles. This range is made possible by the A380's 11 fuel tanks, which have a total capacity of 250 metric tons (320,000 liters).
The A380's fuel management system is a sophisticated piece of engineering that handles fueling and defueling operations on the ground, as well as fuel flow to engines and between tanks while airborne. This system can move fuel between tanks to optimize the aircraft's center of gravity, reduce wing bending, and maintain fuel temperature within an acceptable range.
The development of the A380's fuel management system involved the use of Model-Based Design, with tools like Simulink and Stateflow being used to model the system's control logic. This process allowed engineers to work independently on individual components, such as tanks, pumps, valves, and electrical components.
The A380's fuel efficiency has been a key focus for Airbus and its customers. For example, Singapore Airlines CEO Chew Choong Seng noted that the A380 burned 20% less fuel per seat-mile than their 747-400 fleet. Additionally, Emirates' Tim Clark highlighted the aircraft's improved fuel economy at higher speeds.
The A380's fuel efficiency and range capabilities have been further enhanced by Airbus' ongoing innovations. In 2010, Airbus announced a new A380 build standard with a strengthened airframe structure and increased wing twist, resulting in better payload/range performance and an extended range of 100 nautical miles.

The A380 has a range of over 8,000 miles
The Airbus A380 is the largest commercial aircraft currently in operation. It has a range of more than 8,000 miles, enabled by its 11 fuel tanks, which have a combined capacity of 250 metric tons (320,000 liters).
The A380's fuel management system is a key factor in achieving this impressive range. This system handles fueling and defueling operations on the ground, as well as fuel flow to engines and between tanks while airborne. By optimising the aircraft's center of gravity and reducing wing bending, the system ensures efficient fuel usage and extends the aircraft's range.
The development of the A380's fuel management system involved the use of Model-Based Design, with tools like MATLAB, Simulink, and Stateflow. This approach allowed Airbus engineers to model and simulate the control logic of the fuel management system, accelerating the development process. The model comprised 45 top-level charts, nearly 6000 states, and over 8700 transitions, defining various modes of operation on the ground and in flight.
The A380's range and fuel efficiency have been a key focus for Airbus. In 2010, the company announced a new build standard that included a strengthened airframe structure and an increase in wing twist, resulting in improved payload/range performance. Additionally, the A380's modern engines and aerodynamic improvements contribute to better fuel economy and lower noise levels compared to other aircraft.

The A380's fuel management system was developed using MATLAB and Simulink
The Airbus A380 is the largest commercial aircraft currently in operation and has a range of more than 8,000 miles. To enable such long non-stop flights, the A380's 11 fuel tanks have a capacity of 250 metric tons (320,000 liters). Another source, however, states that the hard-line A380-800 fuel-tank capacity is 315,292 liters.
The A380's fuel management system handles fueling and defueling operations on the ground, as well as fuel flow to engines and between tanks while airborne. The system can move fuel between tanks to optimize the aircraft's center of gravity, reduce wing bending, and keep fuel within an acceptable temperature range.
To develop the A380's fuel management system, Airbus engineers used Simulink and Stateflow to model the system's control logic, which comprises 45 top-level charts, almost 6000 states, and more than 8700 transitions. This model defines modes of operation on the ground and in flight. The functionality within each top-level mode is grouped into subcharts, enabling engineers to work independently on individual components in the hierarchy.
The team also developed a parameterized plant model of the tanks, pumps, valves, and electrical components using Simulink. Engineers can set parameter values to configure this model to represent fuel systems for any Airbus aircraft. A MATLAB-based user interface enables suppliers, airline customers, maintenance engineers, and other Airbus teams to visualize how the fuel management system works and interacts with other aircraft systems.
Using Model-Based Design, the team was able to validate requirements months earlier than was previously possible and simulate multiple simultaneous component failures. This gave them confidence that the control logic would be able to manage any failures in the system's 21 pumps, 43 valves, and other mechanical components.

The A380's fuel economy is better at Mach 0.86 than at 0.83
The Airbus A380 is the world's largest passenger airliner and was in production from 2005 until 2021. It is the only full-length double-decker jet airliner and has a range of more than 8,000 miles. To enable such long non-stop flights, the A380 has 11 fuel tanks with a total capacity of 250 metric tons (320,000 liters).
The A380's fuel efficiency can be attributed to several factors. Firstly, it burns 20% less fuel per seat-mile than the 747-400, its predecessor. Secondly, the A380 utilizes a sophisticated fuel management system that optimizes the aircraft's center of gravity and reduces wing bending. This system also ensures that the fuel remains within an acceptable temperature range. Additionally, the A380's airframe is made from composite materials, with 20% of its structure composed of carbon-fiber reinforced plastic, which reduces weight and improves fuel efficiency.
The A380's fuel economy and range can also be enhanced through operational strategies. For example, by flying in formation with another aircraft, taking advantage of wake updraft, the A380 can save up to 12% of its fuel. Additionally, flying at subsonic speeds instead of transonic speeds can result in significant fuel savings. According to a 2024 research project, a subsonic aircraft with turboprop propulsion would save 21% of fuel compared to a conventional design, while a 2014 analysis found that a slower aircraft flying at a 33% lower Mach number would have 36% less fuel consumption.
