What is MIDU on Boeing 737? (Multipurpose Interactive Display Unit)

The Multipurpose Interactive Display Unit (MIDU) on the Boeing 737 is a critical component of the aircraft’s cockpit. It serves as a multifunctional display system that provides pilots with essential information and facilitates their decision-making process during a flight. The MIDU integrates various systems and applications, allowing pilots to access important data related to flight controls, navigation, engine parameters, communication, and more.

As the name suggests, the MIDU is an interactive display unit, meaning that pilots can interact with it using touch or cursor control inputs. This interactive capability enhances the ease of use and efficiency of the system, enabling pilots to navigate through menus and information screens with ease. Furthermore, the MIDU’s high-resolution display offers clear and detailed graphics, ensuring that the information displayed is easily readable and comprehensible.

The MIDU is a crucial tool in modern aviation, providing pilots with a centralized location for accessing vital information that contributes to safe and efficient flight operations. Let’s dive deeper into the different functionalities and features of the MIDU on the Boeing 737 aircraft.

The Features of Multipurpose Interactive Display Unit

The Centralized Information Hub

One of the primary functions of the Multipurpose Interactive Display Unit is to serve as a centralized information hub for pilots. The MIDU displays a variety of critical data, including flight parameters, system status, weather conditions, and navigational information. The displayed information is presented in a clear and organized manner, ensuring that pilots can quickly access the details they need.

For example, the MIDU can provide pilots with real-time information about aircraft speed, altitude, and heading. It also presents critical engine parameters, such as fuel quantity, oil pressure, and temperature. This real-time data allows pilots to monitor the aircraft’s performance and make informed decisions during different phases of the flight.

Moreover, the MIDU integrates weather radar and satellite data, providing pilots with up-to-date weather information. This allows them to anticipate weather conditions along the planned route and make necessary adjustments, ensuring a safe and comfortable flight. Additionally, the MIDU displays navigational charts, including airport layouts, approach procedures, and airway information, enhancing pilots’ situational awareness and aiding in efficient navigation.

Overall, the MIDU’s centralized information hub plays a crucial role in providing pilots with the data they need to make timely and informed decisions, contributing to the safe and efficient operation of the Boeing 737.

Communication and System Control

Another significant feature of the Multipurpose Interactive Display Unit is its integration with communication and system control functions. The MIDU allows pilots to monitor and control various aircraft systems, including the communication and navigation systems, flight controls, and engine parameters.

With the MIDU, pilots can access and manage the aircraft’s communication systems, including radio frequencies, navigation aids, and transponder settings. The ability to control these systems from a single interface simplifies pilots’ tasks and reduces workload, allowing them to focus on flying the aircraft safely.

Furthermore, the MIDU provides pilots with access to the aircraft’s flight control systems. Pilots can monitor the status of flight control surfaces, such as ailerons, elevators, and rudder, ensuring their proper functioning. In the case of any abnormality, the MIDU alerts pilots, enabling them to take appropriate actions promptly.

Additionally, the MIDU offers control over engine parameters, allowing pilots to monitor engine performance and make necessary adjustments. The system displays crucial engine information, such as thrust, fuel flow, and temperatures, enabling pilots to detect any anomalies and take appropriate actions to maintain optimal engine operation.

With its communication and system control capabilities, the Multipurpose Interactive Display Unit enhances pilots’ situational awareness and enables efficient monitoring and management of crucial aircraft systems.

Enhanced Safety and Reduced Workload

The Multipurpose Interactive Display Unit significantly contributes to flight safety and workload reduction for pilots. By providing all the necessary information on a single display, the MIDU reduces the need for pilots to refer to multiple source documents or displays. This consolidation of information not only saves time but also helps maintain focus on flying the aircraft.

The intuitive and user-friendly interface of the MIDU enables pilots to access information quickly and efficiently. The touch or cursor control inputs allow for easy navigation through menus and screens, ensuring a seamless user experience. Moreover, the high-resolution display ensures that all information is presented clearly, minimizing the chances of misinterpretation or misunderstanding of critical data.

Furthermore, the MIDU features built-in alert and warning systems to improve safety. In the event of any abnormal conditions or malfunctions, the MIDU immediately alerts pilots, allowing them to take necessary action promptly. This proactive approach enhances safety and ensures that potential issues are addressed before they escalate.

Overall, the Multipurpose Interactive Display Unit plays a vital role in enhancing flight safety and reducing pilots’ workload. By providing a centralized location for accessing critical information and offering intuitive controls, the MIDU contributes to a safer and more efficient flight operation.


The Multipurpose Interactive Display Unit on the Boeing 737 is a valuable tool that provides pilots with essential information and facilitates efficient decision-making. Its centralized information hub, communication and system control capabilities, and contribution to safety and workload reduction make the MIDU an integral part of the aircraft’s cockpit.

As aviation technology continues to evolve, the importance of interactive display units like the MIDU is expected to grow. These advanced systems empower pilots with the information they need and streamline their tasks, ultimately ensuring safer and more efficient flights.
