What is CAPC on Boeing 777? (Cabin Area Control Panel)

The Cabin Area Control Panel (CAPC) is a crucial component of the Boeing 777 aircraft, responsible for controlling and monitoring various cabin systems. It is a centralized control panel located in the flight deck that allows pilots to manage different functions related to the cabin environment, ensuring the safety and comfort of passengers throughout the flight.

The CAPC is essential for the smooth operation of the cabin systems, including lighting, temperature control, ventilation, and various audiovisual functions. It provides pilots with easy access to these critical functions, allowing them to make adjustments as required based on the flight conditions and passenger needs.

The Functions of the Cabin Area Control Panel

The Cabin Area Control Panel on the Boeing 777 is designed to offer pilots comprehensive control over the cabin environment. Let’s take a closer look at the key functions it provides:

1. Lighting Control

The CAPC enables pilots to control the lighting system in the cabin, including overhead lighting, reading lights, and signage illumination. They can adjust the intensity of the lights, set different lighting configurations for different flight phases, and override the automatic lighting system if necessary.

Proper lighting plays a significant role in enhancing passenger comfort and safety during the flight. It allows the crew to create a relaxing ambiance during nighttime flights or provide bright lighting for safety inspections and emergency situations.

2. Temperature Control

The CAPC also provides control over the temperature in different zones of the cabin. It allows pilots to adjust the heating and cooling systems, ensuring the cabin remains at a comfortable temperature throughout the flight. The temperature control feature helps prevent passenger discomfort due to extreme temperatures and contributes to a pleasant travel experience.

The Boeing 777 aircraft utilizes advanced air conditioning systems, and the CAPC acts as the interface for pilots to manage the temperature settings. This helps maintain a balanced temperature throughout the cabin, accounting for factors such as outside temperature, passenger load, and heat generated by aircraft systems.

3. Ventilation Control

Proper ventilation is crucial for maintaining a fresh and clean cabin environment. The Cabin Area Control Panel allows pilots to regulate the airflow and ventilation systems on the Boeing 777, ensuring a continuous supply of fresh air throughout the flight. The ventilation control feature helps remove odors, control humidity levels, and reduce the spread of airborne contaminants.

The CAPC enables pilots to adjust the airflow rate, direction, and temperature in various zones of the cabin, providing personalized comfort options for passengers. It also incorporates features such as HEPA filters to remove allergens and improve air quality.


The Cabin Area Control Panel (CAPC) is a critical component of the Boeing 777 aircraft, offering pilots centralized control over cabin systems such as lighting, temperature, and ventilation. It plays a crucial role in ensuring passenger comfort and safety throughout the flight.

By providing pilots with easy access to the various functions related to the cabin environment, the CAPC enables them to make necessary adjustments based on flight conditions and passenger needs. This ensures a pleasant travel experience and creates a comfortable ambiance for passengers.

As technology continues to advance, future aircraft may introduce even more sophisticated cabin area control panels, enhancing the overall passenger experience and further optimizing cabin operations.
