What is QT on Airbus A320? (Quart)

The Airbus A320 is a popular narrow-body aircraft commonly used for short to medium-haul flights. It is known for its efficiency, reliability, and advanced technology. One important aspect of the Airbus A320’s systems is the Quart (QT) system. In this article, we will explore what Quart is and how it contributes to the overall performance and safety of the aircraft.

The Role of Quart on Airbus A320

The Quart system on the Airbus A320 is an important component of the aircraft’s fuel management system. It is responsible for monitoring and controlling the distribution of fuel throughout the aircraft during all phases of flight. This system ensures that the engines receive an adequate and consistent supply of fuel, optimizing their performance and efficiency.

The Quart system consists of several components, including sensors, valves, and control units. These components work together to measure the fuel levels in the aircraft’s fuel tanks, monitor the fuel consumption of each engine, and regulate the fuel flow as required. The system also includes safety measures to prevent fuel imbalance, which could lead to stability issues during flight.

One of the key functions of the Quart system is to automatically transfer fuel between different tanks to maintain balance and optimize the aircraft’s center of gravity. This is especially important during maneuvers such as takeoff, landing, and banking turns. By continuously monitoring the fuel levels and adjusting fuel distribution, the Quart system contributes to the overall stability, performance, and safety of the Airbus A320.

How Quart Benefits Airbus A320 Pilots

The Quart system provides several benefits to Airbus A320 pilots, enhancing their ability to effectively manage fuel and ensure a smooth and efficient flight. Here are some of the advantages offered by the Quart system:

1. Optimal Fuel Efficiency: The Quart system ensures that the engines receive the right amount of fuel at all times, maximizing their efficiency and reducing fuel consumption. This results in cost savings for airlines and a reduced environmental impact.

2. Improved Safety: By maintaining fuel balance and preventing fuel imbalance, the Quart system helps enhance the aircraft’s stability and reduces the risk of accidents or incidents caused by fuel-related issues.

3. Enhanced Performance: The Quart system’s ability to manage fuel distribution and maintain balance contributes to the overall performance of the aircraft, ensuring smooth takeoffs, landings, and maneuvers.

4. Simplified Operations: The Quart system automates many of the fuel management tasks, reducing the workload of pilots and allowing them to focus on other critical aspects of flight.

Overall, the Quart system plays a crucial role in optimizing fuel efficiency, enhancing safety, and improving the overall performance of the Airbus A320.


The Quart system on the Airbus A320 is a vital component of the aircraft’s fuel management system. It ensures optimal fuel distribution, maintains balance, and contributes to the overall efficiency, safety, and performance of the aircraft. By automating fuel management tasks and providing pilots with accurate data, the Quart system enhances the overall flying experience and helps airlines operate more cost-effectively. Understanding the role of Quart on the Airbus A320 allows us to appreciate the advanced technology and intricate systems that make this aircraft a popular choice in the aviation industry.
