What is XFR on Airbus A320? (Transfer)

The Airbus A320 is a popular narrow-body aircraft used by airlines around the world. It is known for its efficiency, reliability, and advanced technology. One important feature of the Airbus A320 is the Transfer system, also referred to as XFR. In this article, we will explore what Transfer on Airbus A320 is, how it works, and its significance in the aviation industry.

Understanding Transfer on Airbus A320

Transfer on Airbus A320, abbreviated as XFR, is a system that allows the transfer of various aircraft parameters between different electronic units on the aircraft. These parameters include flight control, navigation, engine data, and more. The Transfer system ensures the seamless exchange of critical information, contributing to the safe and efficient operation of the aircraft.

The Transfer system consists of multiple transfer modules located throughout the aircraft. These modules, also known as XFR modules, are responsible for receiving and transmitting data between the electronic units. They act as intermediaries, ensuring that the necessary information is available to the relevant systems and components.

With the Transfer system, the Airbus A320 benefits from a high level of redundancy and system integrity. The redundancy ensures that even if one transfer module fails, the system can still function properly with the remaining modules. This redundancy is crucial for maintaining safe operations throughout the flight, from takeoff to landing.

The Transfer system also plays a vital role in the Airbus A320’s fly-by-wire flight control system. Fly-by-wire is a technology that replaces conventional manual flight controls with electronic ones. With the Transfer system, the flight control units can exchange critical flight data, such as control input commands and sensor information, in real-time. This enables precise and responsive control of the aircraft, enhancing safety and efficiency.

The Significance of Transfer on Airbus A320

The Transfer system on the Airbus A320 is of great significance in the aviation industry for several reasons:

  • Enhanced Safety: The Transfer system provides redundancy and system integrity, ensuring that critical information reaches the necessary systems and components. This redundancy is essential for safe flight operations and enhances the overall safety of the aircraft.
  • Efficient Data Exchange: The Transfer system enables the seamless transfer of data between electronic units, allowing for efficient communication and coordination. This ensures that all systems have the necessary information to operate optimally, contributing to the smooth functioning of the aircraft.
  • Fly-by-Wire Technology: The Transfer system is a crucial component of the Airbus A320’s fly-by-wire flight control system. This advanced technology provides precise control and responsiveness, enhancing flight safety and pilot handling.

Overall, the Transfer system on the Airbus A320 is a fundamental element that facilitates the exchange of critical information between various electronic units. Its reliability, redundancy, and role in fly-by-wire technology make it an essential feature of this popular aircraft.


In conclusion, the Transfer system, also known as XFR, plays a crucial role in the Airbus A320 aircraft. It enables the seamless transfer of critical data between different electronic units, ensuring the safe and efficient operation of the aircraft. The redundancy, system integrity, and significance in fly-by-wire technology make the Transfer system an integral part of the Airbus A320’s advanced capabilities. Understanding and appreciating the importance of the Transfer system allows us to recognize the level of sophistication and innovation present in modern aircraft like the Airbus A320.
