Boeing 787 Common Core System
The Boeing 787 Common Core System (CCS) represents a major advancement in aviation information systems, integrating data across the entire aircraft. The Boeing 787 Dreamliner, with its CCS, marks a significant step forward, allowing seamless communication and optimized functionality. In this blog post, we explore the history of aviation information systems, leading up to the development of the Boeing 787 Common Core System and its impact on modern aviation.

The History of Information Systems in Aviation
The roots of aviation information systems date back to the early days of commercial flying when simple electromechanical indicators were the only means to provide basic flight information to pilots. As aircraft began to fly longer and higher, the need for more sophisticated data processing and management systems grew. The Flight Data Recorder (FDR), often referred to as the “black box,” was one of the first revolutionary data systems, allowing for post-flight analysis of an aircraft’s performance.
By the 1980s, advancements in digital avionics brought about a significant leap forward. Aircraft like the Boeing 757 and 767 introduced Electronic Flight Instrument Systems (EFIS), replacing traditional analog gauges with digital screens. This transition marked the beginning of more integrated systems that were capable of processing larger amounts of data and presenting it in a more comprehensible format to pilots.

The 1990s and early 2000s saw the birth of Glass Cockpits, which fully digitized all aircraft instruments and added powerful Flight Management Systems (FMS). These systems, paired with advanced Data Link Communication technologies such as ACARS (Aircraft Communications Addressing and Reporting System), allowed airlines to exchange information with their aircraft in real-time, leading to more efficient flight planning and maintenance.

The Common Core System (CCS) in the Boeing 787
The Boeing 787 Common Core System takes the concept of integrated information systems to a whole new level. The CCS acts as the central nervous system of the 787, designed to manage a wide range of aircraft functions, from monitoring maintenance needs to managing cabin systems. The CCS is a distributed computing environment, providing centralized data processing and networking capabilities that connect almost every major system on the aircraft.
Components of the CCS
The CCS consists of several key components that form a robust and reliable network within the aircraft. At its heart is the Core Network Cabinet, which houses a range of modules such as the Ethernet Gateway Module (EGM), Network Interface Module (NIM), and Controller Server Module (CSM). These modules work together to store and distribute software, manage data flows, and ensure system integrity.
- Ethernet Gateway Module (EGM): The EGM plays a critical role in maintaining network security and routing data between the aircraft’s internal systems and the outside world. It provides connections to both the Open Data Network (ODN) and the Isolated Data Network (IDN), ensuring the appropriate segregation of data based on its criticality.
- Network Interface Module (NIM): The NIM handles the distribution of power to other modules and provides a secure interface between different onboard networks. It also monitors the temperature and power conditions within the core network, ensuring that the system runs smoothly and safely.
- Controller Server Module (CSM): The CSM is responsible for data storage and application management within the core network. It provides key services such as onboard authentication, network management, and core network application services, which are vital for the operation of the 787’s onboard systems.
The CCS integrates multiple physical and logical networks, including the ODN and IDN. The ODN connects to non-critical systems such as the in-flight entertainment and cabin services, while the IDN links to flight-critical systems, ensuring that vital operations are secure and isolated from less critical functions.

Benefits of the Boeing 787 Common Core System
The Boeing 787 Common Core System offers numerous advantages, including:
- Enhanced Integration: The CCS connects virtually all onboard systems, from flight controls to cabin management, allowing seamless communication between components. This integration reduces the complexity of wiring and the number of standalone systems, resulting in a more reliable aircraft.
- Data-Driven Maintenance: The CCS is designed to work in tandem with the Central Maintenance Computing Function (CMCF). It continuously monitors the health of the aircraft and provides real-time data to maintenance crews, helping identify and resolve issues before they become serious. This proactive maintenance approach reduces downtime and improves operational efficiency.
- Network Security: The CCS features a layered security architecture, with both the Open Data Network and Isolated Data Network designed to ensure that sensitive flight systems are isolated from less critical systems. This segmentation helps protect the aircraft from potential cybersecurity threats.
The Future of Information Systems in Aviation

As the aviation industry continues to evolve, the role of information systems like the Boeing 787 Common Core System will only grow in importance. The integration of Artificial Intelligence (AI) and Machine Learning (ML) into future aircraft systems could enhance predictive maintenance and optimize operational efficiency even further. Additionally, the advent of 5G and satellite-based internet will likely improve real-time data exchange capabilities, enhancing both passenger experience and aircraft safety.
The Boeing 787’s Common Core System stands as a testament to how far information systems have come in aviation. From the humble beginnings of analog gauges to the highly integrated digital ecosystems of today, the evolution of these systems has fundamentally transformed the aviation landscape, making flying safer, more efficient, and more connected than ever before.
Conclusion
The Common Core System in the Boeing 787 represents the culmination of decades of innovation in aviation information systems. By providing a centralized, secure, and highly integrated data environment, the CCS not only enhances the operational capabilities of the aircraft but also sets the stage for future advancements in aviation technology. As we look to the future, systems like the CCS will continue to push the boundaries of what is possible, making air travel more reliable, efficient, and enjoyable for everyone.
