A. System FunctionThe ac electrical-load distribution system supplies the aircraft navigation systems from the two 26 V ac busbars on the avionics circuit-breaker panel. It also supplies the flight data system from the two 115 V ac busbars on the left circuit-breaker panel.
B. System ComponentsThe primary components of the system are the:
- Avionics circuit-breaker panel (Ref. Fig. 1 and Fig. 2)
- Left circuit-breaker panel (Ref. Fig. 1 Fig. 3)
- 26 V ac busbars
- 115 V ac busbars
C. System OperationThe aircraft inverters supply 26 V ac and 115 V ac to the system busbars. The system busbars supply the navigation systems and the flight data system with 26 V ac and 115 V ac through the circuit breakers.
