What is SYNC on Airbus A320? (Synchronize)

Synchronize, also known as SYNC, is an important feature on the Airbus A320 aircraft that ensures the coordination and alignment of various systems and components. This synchronization process plays a crucial role in maintaining the aircraft’s performance, efficiency, and safety.

In this article, we will delve deeper into the concept of synchronize on the Airbus A320, understanding its significance, and exploring how it functions within the aircraft’s operation.

Synchronization in the Airbus A320

The synchronize system on the Airbus A320 is primarily responsible for the coordination of engines, flight controls, and various other components to optimize the aircraft’s performance. It ensures that all the systems are working in harmony and are synchronized to operate efficiently.

One of the key areas where synchronization takes place is in engine operation. The A320 is typically equipped with two engines, and the synchronize system ensures that both engines are operating at the same thrust settings. This helps in reducing inconsistencies and improves fuel efficiency by ensuring balanced engine performance.

The synchronize system also plays a vital role in the synchronization of flight controls. In an aircraft like the A320, there are various control surfaces, such as ailerons, elevators, and rudders, that work together to maneuver the aircraft. The synchronize system ensures that the movements of these control surfaces are coordinated, allowing for smooth and precise control of the aircraft.

Moreover, the synchronization of various hydraulic systems, electrical systems, and other critical components is facilitated by the synchronize system. This ensures that all systems are functioning harmoniously, reducing the risk of malfunctions and enhancing the overall safety of the aircraft.

In summary, synchronization on the Airbus A320 is crucial for optimizing the aircraft’s performance, improving efficiency, and ensuring the safe operation of various systems and components.

The Functioning of Synchronization

The synchronization process on the Airbus A320 involves several interconnected systems and components working together to achieve a harmonious operation. Let’s explore how some of these systems function:

1. Engine Synchronization

The synchronize system in the A320 ensures that both engines have the same thrust settings and operate harmoniously. It achieves this through the Engine Electronic Control (EEC) system. The EEC receives input from various sensors and determines the desired thrust for each engine. It then sends signals to the engines’ Full Authority Digital Engine Controls (FADECs) to adjust the engine parameters accordingly.

Through this synchronized operation, both engines maintain the same thrust, helping to reduce vibrations and maintain a balance in engine performance. This not only contributes to a smoother flight experience but also optimizes fuel consumption.

2. Flight Control Synchronization

The synchronization of flight controls is integral to the safe and precise maneuvering of the Airbus A320. This coordination is achieved through the aircraft’s Fly-by-Wire (FBW) system, which replaces the traditional mechanical control systems with electronic signals.

The FBW system receives pilot input from the control columns and pedals and translates them into electronic signals. These signals are then transmitted to the Flight Control Computers (FCCs), which interpret and coordinate the movements of the control surfaces accordingly. The synchronize system ensures that these movements are synchronized, enabling the pilot to have smooth and precise control over the aircraft’s flight attitude.

3. System Synchronization

The synchronization of various systems within the Airbus A320 is crucial for the seamless operation of the aircraft. This includes systems such as hydraulics, electricals, avionics, and other critical components.

The synchronize system monitors and coordinates the functioning of these systems, ensuring that they work in harmony. By maintaining synchronization, potential issues and malfunctions are minimized, contributing to the overall safety and reliability of the aircraft.

It is worth noting that the synchronization process involves advanced technology and intricate monitoring systems to ensure effective coordination and precise operations.


Synchronize, or SYNC, plays a vital role in the functioning of the Airbus A320 aircraft. It coordinates engines, flight controls, and various systems to optimize performance, improve efficiency, and enhance safety. Engine synchronization, flight control synchronization, and system synchronization are some of the key areas where this coordination takes place.

The synchronize system ensures that both engines operate at the same thrust, facilitating a balanced engine performance and improving fuel efficiency. It also coordinates the movements of flight control surfaces, enabling smooth and precise aircraft control. Additionally, the synchronization of various systems and components minimizes malfunctions and enhances the overall safety and reliability of the aircraft.

The significance of synchronize on the Airbus A320 cannot be understated. It is a crucial element in the aircraft’s overall operation, contributing to its exceptional performance and reputation in the aviation industry.
