The Boeing 737 is a widely-used commercial aircraft known for its reliability, efficiency, and innovative features. One of the important systems on board the Boeing 737 is the Interconnect (INTC) system. In this article, we will explore what the Interconnect system is, its functions, and its significance in ensuring the safe operation of the aircraft.
The Interconnect system on the Boeing 737 is responsible for providing intercommunication and data exchange between various aircraft systems. It enables the seamless integration of different components, ensuring that they work together effectively. By establishing connections and facilitating communication, the Interconnect system plays a crucial role in the proper operation and monitoring of the aircraft systems.

The Functions of the Interconnect System
The Interconnect system performs several important functions on the Boeing 737. Let’s explore some of its key roles:
1. Communication and Data Exchange
The Interconnect system acts as a communication hub, allowing different systems on the Boeing 737 to exchange vital information. It connects essential components such as avionic systems, flight control systems, electrical systems, and more. This seamless exchange of data ensures that all systems are working in harmony and that the aircraft is operating optimally.
For example, the Interconnect system enables the Flight Management System (FMS) to communicate with the autopilot system, providing necessary guidance and control inputs during flight. It also allows the Engine Control system to communicate with the Fuel Control system, ensuring efficient engine performance and fuel consumption.
Furthermore, the Interconnect system plays a crucial role in facilitating communication between the aircraft systems and the ground-based maintenance systems. This enables real-time data monitoring, diagnostics, and troubleshooting, helping airlines and maintenance crews to quickly identify and address any issues that may arise.
2. Safety and Redundancy
Ensuring the safety of the aircraft and its occupants is a top priority in aviation. The Interconnect system on the Boeing 737 contributes to this by providing redundant paths for critical data and communication. This redundancy ensures that even if one path or system fails, there are alternative routes for the flow of information, reducing the risk of system failures or loss of critical functions.
For example, the Interconnect system ensures redundancy in the communication between the Flight Data Acquisition Unit (FDAU) and other systems. The FDAU collects essential flight data such as altitude, speed, and heading, and transmits it to various systems for monitoring and analysis. The Interconnect system ensures that this data is distributed to multiple systems simultaneously, guaranteeing its availability even if one path is compromised.
Additionally, the Interconnect system plays a vital role in the implementation of the Enhanced Ground Proximity Warning System (EGPWS). The EGPWS provides critical terrain and obstacle avoidance warnings to pilots. The Interconnect system ensures the flow of necessary data between the EGPWS system and other relevant systems, enhancing the aircraft’s safety and providing pilots with vital information to make informed decisions.
3. Integration of System Components
The Boeing 737 consists of numerous complex systems and components that must work together seamlessly for the aircraft to function properly. The Interconnect system acts as the glue that integrates and coordinates the operations of these diverse components.
For instance, the Interconnect system facilitates communication between the Flight Control System (FCS) and the Spoiler Control System (SCS). The FCS controls the aircraft’s primary flight control surfaces, while the SCS manages the deployment and retraction of the spoilers. The Interconnect system ensures that the two systems work harmoniously, providing precise control and stability during different flight phases.
The Interconnect system also facilitates the integration of the Onboard Maintenance System (OMS) with other aircraft systems. The OMS continuously monitors the health and status of various components, providing airlines and maintenance crews with valuable data for maintenance planning and troubleshooting. The Interconnect system enables the seamless exchange of data between the OMS and other systems, ensuring the accuracy and timeliness of maintenance-related information.
The Significance of the Interconnect System
The Interconnect system is a critical component of the Boeing 737 aircraft, playing a pivotal role in ensuring its safe and efficient operation. By facilitating communication, integrating systems, and providing redundancy, the Interconnect system enhances the reliability, performance, and safety of the aircraft.
With advancements in technology, the Interconnect system continues to evolve, adapting to new requirements and integrating innovative features. It remains an essential system in modern aviation, contributing to the success and reputation of the Boeing 737 as a reliable and trusted aircraft for airlines worldwide.
