The rear cockpit avionics bus receives power through which component?

The rear cockpit avionics bus receives power primarily from the front cockpit avionics bus. This configuration allows for centralized power management, ensuring that both the front and rear cockpit can operate efficiently and share critical avionics systems. The front cockpit avionics bus acts as the primary source of power, routing electricity from the aircraft's main power system to both cockpit areas to facilitate the operation of instrumentation and systems.

This hierarchical power distribution is crucial for functionality, as it ensures that the avionics in both cockpits can be powered without the need for separate power sources for each cockpit, simplifying the design and enhancing reliability.
