What You'll Learn
The Airbus A319's fuel burn rate is 733 US gallons/hour
The Airbus A319 is a fuel-efficient aircraft with a fuel burn rate of 733 US gallons per hour. This burn rate is relatively low compared to other aircraft in its class, such as the Boeing 777-200, which has a fuel burn rate of 2218 US gallons per hour. The A319's efficiency is due in part to its aerodynamic design and lightweight composite materials.
The A319's fuel efficiency has significant advantages for airlines and passengers alike. For airlines, the lower fuel burn rate translates to reduced operating costs. With less fuel consumed per hour, the A319 can fly longer distances without refuelling, making it a versatile option for various routes, including long-haul flights. This extended range capability can enhance an airline's operational flexibility and open up new route possibilities.
For passengers, the A319's fuel efficiency contributes to a more environmentally friendly travel option. By burning less fuel, the aircraft produces fewer carbon dioxide (CO2) emissions, reducing the carbon footprint associated with air travel. This aspect aligns with the aviation industry's growing focus on sustainability and its commitment to reducing its environmental impact.
Additionally, the A319's fuel efficiency can lead to more comfortable and convenient travel experiences. With efficient fuel usage, the aircraft can optimise its range and endurance, allowing for more direct routing and fewer refuelling stops. This not only saves time for passengers but also reduces the overall fuel consumption for a given journey, further contributing to the aircraft's environmental benefits.
While the A319's fuel burn rate of 733 US gallons per hour is impressive, it's important to note that fuel consumption can vary based on various factors. These factors include the aircraft's payload, cruising speed, altitude, and operational procedures. For example, flying at optimum altitudes and speeds can further enhance fuel efficiency, while additional fuel may be required for longer flights or when carrying heavier payloads.

The A319's maximum takeoff weight is 68,000 kg
The Airbus A319 is a member of the Airbus A320 family of short- to medium-range, narrow-body, commercial passenger twin-engine jet airliners manufactured by Airbus. The A319 carries 124 to 156 passengers and has a maximum range of 3,700 nautical miles (6,900 km; 4,300 mi).
The A319 is a shortened-fuselage variant of the Airbus A320 and entered service in April 1996 with Swissair, around two years after the stretched Airbus A321 and eight years after the original A320. The aircraft shares a common type rating with all other Airbus A320 family variants, allowing existing A320 family pilots to fly the aircraft without the need for further training. The A319's maximum takeoff weight (MTOW) is 68,000 kg (150,000 lb).
The A319 incorporates removable extra fuel tanks (up to six additional Centre Tanks) installed in the cargo compartment, and an increased service ceiling of 12,500 m (41,000 ft). The range with eight passengers' payload and auxiliary fuel tanks (ACTs) is up to 6,000 nautical miles (11,100 km). The aircraft can also be reconfigured as a standard A319 by removing its extra tanks and corporate cabin outfit, thus maximising its resale value.
The A319 promises fuel savings of up to 15%. The previous A319 generation was retroactively renamed the A319ceo (current engine option). As of May 2025, a total of 1,516 Airbus A319 aircraft have been delivered, of which 1,263 are in service. American Airlines is the largest operator, with 133 A319ceo in its fleet.

The A319 can carry 18,700 kg of fuel
The Airbus A319 is a member of the Airbus A320 family, which is known for delivering outstanding performance in high-altitude airports while lowering fuel burn and carbon dioxide emissions. The A319 can carry 18,700 kg of fuel, which is a significant amount that enables the aircraft to cover long distances.
The fuel economy of an aircraft is a measure of its transport energy efficiency. Several factors influence fuel efficiency, including aerodynamics, weight, engine brake-specific fuel consumption, and propulsive efficiency or thrust-specific fuel consumption. By improving these factors, aircraft manufacturers can reduce fuel burn and increase the range of their planes.
The range of an aircraft is also impacted by the weight of the fuel carried. For long-haul flights, additional fuel is required, which can lead to higher fuel consumption. In some cases, it may be more fuel-efficient to make a halfway stop to refuel, despite the energy losses during descent and climb. This strategy can be advantageous when compared to carrying the extra weight of fuel required for non-stop long-haul flights.
The Airbus A319's fuel capacity of 18,700 kg gives it a competitive range. This range, combined with its fuel efficiency, makes the A319 a versatile aircraft capable of serving various routes, including those with high-altitude airports. The A319's performance and efficiency contribute to its popularity among airlines and help optimize their operations.
Additionally, the A319's fuel capacity and range can be further enhanced through modifications. For example, the A319 CJ variant features additional centre tanks, increasing its range to 6,000 NM and its total fuel capacity to approximately 31,900 kg. These modifications provide greater flexibility for specific layouts and operational requirements, showcasing the adaptability of the A319 platform.
