What You'll Learn
Fuel burn rate: 2,537-2,625 kg/hr
The Airbus A320 is a fuel-efficient aircraft with a fuel burn rate of 2,537-2,625 kg/hr. This burn rate is significantly lower than that of older aircraft, thanks to improvements in engine efficiency and airframe design over the years.
The A320's fuel efficiency can be attributed to several factors. Firstly, Airbus has incorporated fuel-saving measures, such as continuous descent approaches and single-engine taxiing, which can significantly reduce fuel consumption and emissions. Additionally, the A320 may be equipped with wingtip devices, such as wingtip fences or Sharklet blended-winglets, which offer a 3.5% fuel burn reduction on flights over 2,800 km by improving the lift-to-drag ratio.
The specific fuel consumption of the A320 engine also contributes to its efficiency. The CFM56 engine, for example, has a fuel consumption of around 2,400-2,600 kg per hour. This engine is commonly used in the US-operated A320 CEO, and its efficient fuel burn contributes to the aircraft's overall performance.
It is worth noting that the fuel burn rate of the A320 can vary depending on various factors. For instance, the gross weight of the aircraft, the altitude, and the presence of winglets can all impact fuel consumption. Additionally, the A320neo, a newer version of the A320, has an even lower fuel burn rate of 2,005-2,063 kg/hr, demonstrating Airbus's ongoing commitment to improving fuel efficiency.
In comparison to other aircraft, the A320's fuel burn rate is quite competitive. For example, the Airbus A380, a larger aircraft, has a fuel burn rate of less than 3 L/100 km per passenger, while the Boeing 787 Dreamliner and Airbus A350 offer 20% improved fuel efficiency per passenger kilometer compared to previous-generation aircraft.

Sharklet blended-winglets: 3.5% fuel reduction
The Airbus A320's fuel consumption is estimated to be around 2400-2600 kg per hour. However, the actual burn rate is often lower than the estimated burn rate.
Airbus has opted to continue using a version of its Sharklets on its widebody aircraft, including the A350 and A330neo families. Sharklets are Airbus's marketing term for their specific winglet design, featuring smooth transitions between the wing and winglet surfaces. They are designed to reduce drag and improve fuel efficiency.
The integration of winglets with sustainable aviation technologies is crucial for achieving industry emissions reduction targets. While the exact fuel savings depend on sector length and operating conditions, Sharklets typically provide a fuel reduction of around 3.5% on long-haul flights exceeding 3,000 nautical miles. On shorter routes, the fuel savings are proportionally smaller, averaging around 1%.
For example, on medium-haul routes of around 1,000 nautical miles, winglets can save up to 4-5% in fuel consumption compared to non-winglet aircraft. These fuel savings have significant economic benefits, influencing airline fleet planning strategies and aircraft selection. Airlines operating longer sectors achieve faster payback periods, making Sharklets an attractive investment for airlines with long-haul operations.

CFM56-powered A320: 2,400-2,600 kg/hr
The CFM56 engine is available on all Airbus A320 variants. The CFM56-powered A320 has a fuel consumption rate of around 2,400-2,600 kg/hr. This figure is for total fuel burn and is not a cruise burn figure. The actual burn rate is often lower than 2,400 kg/h, which is the figure used for gross calculations.
The CFM56 engine was first introduced in 1982 when Delta Air Lines, United Airlines, and Flying Tigers chose it to re-engine their Douglas DC-8 aircraft. The CFM56 was later selected to re-engine the Boeing 737, and in 1987, it was chosen to replace the IAE V2500 engine for the A320. The CFM56 has lower fuel consumption than older engines for the 737 and has achieved strong sales.
As of July 2016, 9,860 CFM56-5 engines have been built for the Airbus A320ceo and A340-200/300. CFM International has delivered more than 31,000 engines overall, with 24,000 in service and 560 operators. The CFM56 is the most-used high-bypass turbofan, with over 800 million engine flight hours.
The Airbus A320 family is a series of narrow-body airliners that accommodate 150 to 186 passengers. The A320 has a maximum takeoff weight of 73,500 kg and a range of 5,740-6,940 kilometres. The A320neo, a re-engined version of the A320, entered service in 2016.

A320neo: 2,005-2,063 kg/hr
An Airbus A320neo burns 2,005-2,063 kg of fuel per hour. This is a more fuel-efficient model than the standard A320, which burns 2,537-2,625 kg/hr. The A320neo's fuel efficiency is due in part to its use of wingtip fences or Sharklet blended-winglets, which were introduced for the A320 model in 2009. These additions offer a 3.5% fuel burn reduction on flights over 2,800 km.
The A320neo's fuel efficiency is also a result of its lightweight composite materials. The weight of an aircraft is a crucial factor in fuel consumption, as heavier planes require more fuel to fly the same distance as lighter ones. This is why long-haul flights, which require carrying more fuel, tend to be less fuel-efficient.
The number of passengers on board can also impact fuel efficiency per person. For example, a plane flying with half its seats empty will be less fuel-efficient per person than a full flight.
It's worth noting that the A320neo's fuel burn rate may fluctuate depending on various factors such as altitude, speed, and payload weight. For instance, flying 600m below the optimum altitude can increase fuel consumption by 600 kg per hour.
Airbus has also proposed other measures to improve fuel efficiency, such as direct routing, which can save up to 190 kg of fuel per flight by reducing the distance travelled.

A321neo: 2,400 kg/hr
The Airbus A320 series of aircraft are some of the most popular in the world, with a range of different models serving a variety of functions. One of the most important considerations for any airline when choosing an aircraft is fuel efficiency, and the A320 family offers a range of options in this regard.
One of the most fuel-efficient variants of the A320 is the A321neo, which burns an average of 2,400 kg of fuel per hour. This is a significant improvement over the base A320 model, which burns around 2,537-2,625 kg of fuel per hour. The lower fuel burn of the A321neo is due in part to its more efficient engines, as well as aerodynamic improvements such as wingtip devices, which help to reduce drag and improve overall fuel efficiency.
The fuel efficiency of the A321neo is not just a result of its engines and aerodynamics, but also a number of other factors. For example, the A321neo's lightweight composite materials help to reduce its overall weight, leading to lower fuel consumption. In addition, Airbus has implemented a number of operational procedures that can further reduce fuel burn, such as direct routing, optimizing cruise speed, and reducing the amount of fuel carried on board.
Overall, the A321neo's fuel efficiency is a testament to Airbus's ongoing commitment to reducing fuel consumption and emissions. With each new generation of aircraft, Airbus has made significant strides in fuel efficiency, and the A321neo is a clear example of this progress. For airlines and passengers alike, the A321neo offers a more fuel-efficient option for medium-haul flights, helping to reduce the environmental impact of air travel.
