7.2 Aircraft Computer System (ACS) Interfaces

The ACS is responsible for the following fuel system functions:
1. Calculating and Monitoring Fuel Quantities
2. Monitoring and Controlling Fuel Balancing through Fuel Crossfeed
3. Monitoring Fuel Temperature and Pressure
4. Controlling Fuel Shutoff Valves and Electric Fuel Pumps
The ACS monitors inputs from various sensors throughout the fuel system and based
on these inputs determines the fuel system status and activates the electric fuel
pumps and fuel system valves automatically as necessary for normal operation.
Sensors and components on the right side of the fuel system reports directly to the
Right ACS, while sensors and components on the left side reports directly to the Left
ACS
The pilot has direct fuel system control inputs through the FUEL synoptic on the MFD
and can view system status as reported by the ACS from systems sensors, activate
the electric fuel pumps, or initiate manual fuel balancing.
Pilot inputs through the MFD are routed through the PFD to the ACSs which use
these commands to turn on and off applicable Electronic Circuit Breakers (ECBs).
The ECBs for the fuel system are located within the Aft Power Distribution Center in
Electronic Circuit Breaker Units (ECBUs) four and five.
