Which circuit control system is responsible for both the front and rear cockpit avionics?

The front and rear cockpit avionics in the T-6 aircraft are managed by the FWD AVI circuit breaker. This circuit breaker plays a crucial role in protecting and controlling the avionics systems for both cockpits. When the circuit breaker is engaged, it allows power to flow to the avionics, enabling instrumentation and communication systems essential for flight operations. Additionally, the circuit breaker serves as a safety measure, preventing electrical overloads by interrupting power if there is a fault.

Understanding the function of the FWD AVI circuit breaker is important for pilots and maintenance personnel, as it directly impacts the operational readiness and safety of the avionics systems used during flight training and missions. The other options relate to different electrical functions within the aircraft but do not specifically control the avionics systems for both cockpits.
