Which statement about the integrated avionics system is FALSE?

• A. IAC1 supports the forward cockpit and acts as a backup for the rear cockpit for redundancy.
• B. IAC2 supports the rear cockpit and acts as a backup for the forward cockpit for redundancy.
• C. Except for the heads up display (HUD) in the forward cockpit, the integrated avionics system display configuration is identical for both forward and rear cockpits.
• D. IAC1 is the primary computer for both cockpits while IAC2 remains in standby.

Answer: (C)

The system uses two integrated avionics computers to provide redundancy between the forward and rear cockpits, with each cockpit receiving data and displays through the IACs but arranged to fit its crew role. The forward cockpit has a heads‑up display, which presents flight information in a way that the rear cockpit does not mirror. Because of this and because each cockpit’s displays are arranged to support its pilot’s tasks, the display setups are not simply identical mirrors with a single HUD added in front. In other words, even though both cockpits access the same avionics data, the way that data is presented and which screens are active or primary can differ between the forward and rear positions.

That’s why the statement about identical display configurations except for the HUD is not correct. The redundancy and cockpit-specific presentation mean the two sides are not just different by the HUD; their displays and control flows are configured to serve each crew’s needs.
