What is RMCP on Boeing 737? (Radio Management Control Panel)

The Radio Management Control Panel (RMCP) is a crucial component of the Boeing 737 aircraft’s avionics system. It is a device located in the cockpit that allows pilots to manage and control the communication and navigation systems of the aircraft. The RMCP provides a centralized interface for the pilot to interact with the various radios and navigation equipment on board, ensuring efficient and effective communication with air traffic control and other aircraft.

Boeing has continuously improved the RMCP over the years in response to advancements in technology and industry requirements. The latest versions of the Boeing 737 feature an advanced RMCP that integrates digital capabilities and enhanced functionality, providing pilots with more precise control and increased situational awareness.

Let’s delve deeper into the features and functions of the Radio Management Control Panel on the Boeing 737.

The Functions of the Radio Management Control Panel

The Radio Management Control Panel on the Boeing 737 serves several critical functions that contribute to the safe and efficient operation of the aircraft. These functions include:

1. Communication Control

The RMCP allows the pilot to control the communication radios of the Boeing 737. This includes the selection and tuning of radio frequencies, such as those used for air traffic control communications, weather briefings, and communication with other aircraft. The pilot can easily switch between different communication channels and adjust the volume levels to ensure clear and effective communication.

2. Navigation Control

The RMCP also provides navigation control capabilities for the Boeing 737. Pilots can use the panel to select and configure navigation systems, such as the Inertial Navigation System (INS) and Global Positioning System (GPS). They can input flight plans, adjust waypoints, and monitor the aircraft’s position and course on the navigation displays. The RMCP allows for precise navigation, enhancing the aircraft’s ability to follow predetermined routes and accurately reach its destination.

3. Mode Control

The Radio Management Control Panel also enables pilots to manage the different operating modes of the communication and navigation systems. It allows them to select the appropriate mode for different phases of flight, such as departure, enroute, and approach. By choosing the correct mode, pilots can ensure that the aircraft’s communication and navigation equipment is optimally configured to meet the specific requirements of each phase. This flexibility enhances operational efficiency and safety.

Design and Interface

Boeing has implemented a user-friendly design for the Radio Management Control Panel, featuring an intuitive interface that facilitates easy operation by the pilots. The panel is typically located in the center pedestal of the cockpit, within easy reach of the pilot and copilot.

The RMCP consists of a display screen and control knobs/buttons. The display screen presents important information, such as selected frequencies, navigation data, and system status. The control knobs and buttons allow pilots to interact with the panel, adjust settings, and make selections.

Integration with Flight Management System

The Radio Management Control Panel is closely integrated with the Flight Management System (FMS) on the Boeing 737. The FMS is responsible for managing and controlling the aircraft’s flight plan, autopilot functions, and performance calculations.

Through this integration, the RMCP can receive flight plan data from the FMS and automatically tune the communication and navigation radios to the relevant frequencies. This automation eliminates the need for manual tuning, reducing pilot workload and ensuring accurate frequency selection. The integration also allows the RMCP to display important flight plan information, such as waypoints and groundspeed.


The Radio Management Control Panel (RMCP) plays a vital role in the communication and navigation systems of the Boeing 737. It enables pilots to manage the radios, navigate the aircraft, and select the appropriate modes for different flight phases. The user-friendly design and integration with the Flight Management System make the RMCP an essential tool for pilots, enhancing operational efficiency and safety.

With continuous advancements in technology, Boeing has ensured that the RMCP keeps pace with industry requirements and provides pilots with the necessary tools to safely operate the Boeing 737. As aviation continues to evolve, the RMCP will undoubtedly continue to play a crucial role in the future of flight.
