What is CSCP on Boeing 737? (- Cabin System Control Panel)

The Cabin System Control Panel (CSCP) is an integral part of the cockpit in a Boeing 737 aircraft. It plays a crucial role in monitoring and controlling various systems and functions related to the cabin. The CSCP provides the pilots with a centralized interface to manage the aircraft’s environmental and safety systems, ensuring a safe and comfortable flight experience for passengers.

The Functionality of the Cabin System Control Panel

The Cabin System Control Panel on the Boeing 737 consists of multiple switches and indicators, each serving a specific purpose. Let’s explore some of the key functionalities of the CSCP:

The Environmental Control System

One of the crucial functions of the CSCP is to control the aircraft’s Environmental Control System (ECS). The ECS is responsible for maintaining a comfortable cabin environment, including temperature, humidity, and air circulation. The CSCP allows the pilots to adjust the temperature settings, activate or deactivate the air conditioning and heating systems, and monitor the cabin pressurization status.

Additionally, the CSCP provides controls for the airflow and temperature circulation within the cabin. The pilots can control the airflow direction and intensity using the CSCP switches to ensure optimal comfort for passengers in different areas of the aircraft.

The Lighting System

The Cabin System Control Panel also includes controls for the lighting system inside the cabin. The lighting system plays a crucial role in creating a pleasant ambiance and providing appropriate illumination levels for different flight phases.

The CSCP allows the pilots to control the main cabin lights, such as the overhead panel, sidewall lights, and floor lighting. They can adjust the brightness levels and turn on or off specific light sources as per the requirements of the crew and passengers.

The Emergency System

In case of an emergency, the CSCP provides essential controls to ensure the safety of the passengers and crew. The panel includes switches for emergency lighting, which can be activated to illuminate the cabin during an evacuation, ensuring clear visibility of emergency exits and evacuation routes.

Moreover, the CSCP also integrates controls for the cabin interphone system, allowing the pilots to communicate with the flight attendants and coordinate emergency procedures effectively. This ensures a prompt and coordinated response in critical situations, prioritizing the safety and well-being of everyone on board.


The Cabin System Control Panel (CSCP) is a vital component of the cockpit in a Boeing 737 aircraft. It empowers the pilots with the ability to manage and monitor various cabin systems, including the environmental control, lighting, and emergency systems. By providing centralized control and monitoring capabilities, the CSCP ensures a safe and comfortable flight experience for passengers. It is a testament to the advanced technology and meticulous design that goes into making Boeing 737 one of the most reliable and trusted aircraft in the aviation industry.
