The Flight Control Data Concentrator, known as FCDC, is a crucial component of the Airbus A320 aircraft’s flight control system. It plays a central role in collecting and processing flight control data from various sensors and sources on the aircraft. This data is then used to provide inputs to the flight computers, enabling the aircraft’s flight control system to operate effectively and safely.
As an essential part of the flight control system, the FCDC is responsible for consolidating and distributing flight control data to the appropriate flight control computers and systems. It serves as a communication hub, gathering information from diverse sources and ensuring that it is available to the relevant systems for analysis and decision-making.
The FCDC is designed to handle a vast amount of data from various sensors and systems, including control surface sensors, air data sensors, and other flight control-related components. It continuously collects data from these sources and channels it to the flight control computers in real-time, enabling the aircraft’s control surfaces to respond accurately and promptly to pilot inputs. This capability is critical for the safe and efficient operation of the Airbus A320.

The Role of Flight Control Data Concentrator
The Flight Control Data Concentrator performs several vital functions within the flight control system of the Airbus A320. Let’s explore its main roles in more detail:
Data Consolidation
The FCDC acts as a data consolidator, collecting flight control data from various sources throughout the aircraft. This includes inputs from control surface sensors, such as the ailerons, elevators, and rudder, as well as data from air data sensors, such as angle of attack and airspeed sensors. By consolidating this data into a unified format, the FCDC ensures that all relevant flight control information is available to the flight control computers.
Through its data consolidation function, the FCDC helps to eliminate data redundancies and inconsistencies, ensuring that the flight control system operates with accurate and reliable information. This is crucial for maintaining optimal flight control and enhancing the overall safety of the aircraft.
Data Distribution
Once it consolidates the flight control data, the FCDC distributes it to the appropriate flight control computers and systems. This data distribution process involves transmitting the collected data in real-time, ensuring that the flight control computers receive the necessary inputs to make informed decisions.
The FCDC also performs data validation and filtering tasks to ensure that only accurate and relevant information is provided to the flight control computers. By verifying the integrity of the data and filtering out any erroneous or anomalous inputs, the FCDC enhances the reliability and accuracy of the flight control system.
Redundancy and Fault Tolerance
In order to ensure the highest level of safety and reliability, the Flight Control Data Concentrator employs redundancy and fault-tolerant design principles. The FCDC is equipped with multiple redundant channels and subsystems, allowing it to continue functioning even in the event of component failures or malfunctions.
Redundancy in the FCDC architecture enables it to seamlessly switch between different channels and subsystems, ensuring continuous data transmission even in the face of failures. This redundancy feature significantly enhances the overall reliability and fault tolerance of the flight control system, minimizing the risk of single-point failures.
Conclusion
The Flight Control Data Concentrator (FCDC) forms an integral part of the Airbus A320 aircraft’s flight control system. Its role in consolidating and distributing flight control data is crucial for the safe and efficient operation of the aircraft. By collecting data from various sensors and channels, the FCDC ensures that accurate and reliable information is available to the flight control computers, enabling them to make informed decisions.
The FCDC’s redundancy and fault-tolerant design enhance the overall reliability of the flight control system, minimizing the risk of failures. With its critical functions and capabilities, the Flight Control Data Concentrator contributes significantly to the overall safety and performance of the Airbus A320.
